What Is a CNC Punch Press?

Punch Presses are generally used in the Sheet metal industry; however they may be employed in other types of industry where the process of punching out shapes of different materials is required.

 

The punch press is used for cutting and forming material into various shapes and sizes and is a type of machine press. These presses may be very large CNC operated machines which hold large complex die sets, or they may be small manually operated machines which only hold one simple die.

 

Die sets usually consist of ‘female’ dies and ‘male’ punches, and when pressed together with the desired material placed between them, may form a hole or even deform the material (workpiece) into the desired shape of form. The punch is fixed to the end of a ram which moves up and down during the punching process in a vertically linear motion, and the dies and punches are removable to enable different shapes and holes to be formed into the workpiece.

 

There are mainly two types of common machines and these are generally large frame metal pieces of equipment. These are C type frames and portal type frames. On the C type frame there is a hydraulic ram set at the top part which allows the punching process to be carried out. On the portal type frame, the ram is cantered within the frame to prevent frame distortion and deflection.

 

Punch press machines all have a bed or table with rollers or brushes incorporated into them to enable the workpiece or the sheet of metal to travel with low friction. Brushes are mainly employed when minimal scratching or similar marks are not desirable, and the brushes provide a suitable finish to the material. Brushed aluminum or highly polished steels are an example of this process.

 

Punch presses are machines used for processing sheets of material, usually sheet metal, and they perform the operation of forming or stamping the sheet material at specified areas. Many of these machines will have a system by which they are controlled, and CNC operations allow for automatic modes determined by a pre-built program.

 

A punch press is characterized by some basic parameters and these will include:

 

  • Type of tool shop

 

  • Tool shop capacity

 

  • Size of working area

 

  • The working force (20 tons for example)

 

There are different types of CNC punch presses and they include the hydraulic punch press, the mechanical punch press and the flywheel driven press. Punch presses are often referred to by their tonnage, and the sizing tooling needed for a specific task is a straight forward process as the tonnage required to form and cut most materials is well known.

The Different Types of Wall Mount That Will Suit Your Needs

Wall mount is the more convenient way to display LCD and Plasma television sets. Having your TV mounting on the wall will give you a lot of free space. It is also advantageous if you have a small space to work on. Mounting a flat screen LCD monitor is as simple as hanging a picture frame with the use of a mount. Before going out the buy a mount for your television set, it is best to educate yourself with what is available in the market right now. There are actually three types of wall mounts to choose from.

 

  1. Low-profile TV Wall Mount:

This is usually the cheapest and easiest to install. The only disadvantage of buying this kind of mount is that you can longer adjust the TV set once it has been mounted. This type is also called flat or flush mounts.

 

  1. Titling Wall Mount:

From the name itself, this mount has a mechanism that will allow you to tilt your TV vertically for a more ideal viewing. This is also an affordable choice and is not that difficult to install. This is ideal if you will be mounting a television high on the wall.

 

  1. Full-motion Mount:

This is also known as also known as articulating mounts or cantilever mounts. Full motion wall mounts are the best solution if you want to be able to adjust your TV in all directions. You have the option to adjust the TV set in all angles as well as move it away from the wall for better TV viewing. This is most expensive among the three types of mounts. Installing a full-motion wall mount may also be a challenge because of its moving parts. You want to get some help installing this type of mount.

 

Wall mount is made from heavy duty materials allowing it to carry the weight of the TV monitor. When buying a flat screen LCD or plasma TV, it is advisable to check with the retailer the best mount to use for your purchase. LCD Wall mounts can be adjusted and also come in different sizes. There are some TV sets that actually have a specific wall mount suited for the brand. You may also ask them if they will handle the mounting of the new TV that you purchased. This will make the job faster and easier if a professional can do it for you.

What Is a Swiss Lathe?

A Swiss lathe is a style of lathe in which the collet, or holding mechanism, is recessed behind a guide bushing. Swiss lathes are also being known as Swiss turning centers, Swiss automatic lathes or Swiss screw machines. A Swiss lathe is different from a traditional lathe in that the collet, which holds the bar stock, is not directly exposed to the tooling and bed of the lathe. This type of configuration allows this machine tool certain benefits over a traditional type of lathe.

 

The Swiss lathe’s advantages over a traditional lathe is largely because it uses a guide bushing. The purpose of the guide bushing is to provide additional support to the stock material as the part is being turned or machined. The guide bushing fits closely, but not tightly, around the bar stock material. Supporting the bar stock material, a guide bushing functions in a similar manner as a steady rest would on the carriage of a traditional lathe.

 

Swiss-style lathes generally hold better tolerances on parts because the turning operations are performed within close proximity to this guide bushing. The guide bushing provides rigidity to the turned part because only a minimal amount of stock is exposed after leaving the bushing until the turning tools are engaged. With the rigidity that the guide bushing imparts on the stock, these machines are particularly well adapted for holding tight tolerances. Another payoff is the Swiss style lathe’s ability to turn small-diameter parts or parts with large length-to-diameter ratios. Tool chatter typically is minimized because of the tool/guide bushing juxtaposition.

 

There are two types of Swiss lathe machine tools. Mechanical lathes use cams, gearing systems and mechanical linkages to move the headstock and manipulate the collet and tooling. These types of machines have been replaced in many places by computer numerical control (CNC) Swiss lathes.

 

A CNC Swiss lathe will utilize many computer-controlled components. A great number of these components can be adjusted while the machine is in operation. The advantage of a CNC Swiss lathe is that the precision of a traditional machine is maintained while the functionality of the machine is increased with the addition of a computer and its controlled components.

 

Modern types of CNC Swiss lathes might include multiple axis and live secondary tooling, moving tail stocks or secondary spindles. Depending on the desired part configuration, some Swiss lathes have the capability of turning and machining parts complete. This eliminates the need for secondary operations.

 

A disadvantage with all Swiss lathes is the bar stock remnants. These generally are longer than those found on a traditional type of lathe and generally would be considered scrap. Long remnants are the result of the configuration of the collet and guide bushing in this machine.

Chest Waders – Advice on Picking Your Next Set

Having a good pair of chest waders out in the swamps can make the difference between a great trip and a miserable trip. Anyone who has pulled on a pair of bad waders knows that miserable feeling you get when you feel water trickling in, or the nasty chill of cold water in a fast-moving river. When you are looking for a pair of chest waders you are going to want to match the wader to the most common activity.

 

You have essentially two choices in wader style. Stockingfoot and Boot Foot. A stocking foot chest wader is like a pair of kids pajamas. They are completely waterproof, but the feet are like stockings. You need to purchase a pair of separate boots to protect the stocking feet. Boot foot chest waders are just like they sound a pair of waders with a built-in boot. The main problem with boot foot waders is that they can be a bit heavier and clumsier when working through water with a muck bottom. The other issue we have noticed with boot foot waders is that they tend to begin leaking where the top of the boot meets the leg of the wader.

 

When looking for wading boots to go over a pair of stocking-foot waders, order one size larger than your shoe size. When considering the soles on the boots, consider that cleated soles are durable general purpose soles. They are good on wet banks, mud and snow, but not so safe on rocks underwater. Felt soles are excellent on bare rocks and concrete and under water, but very slippery on wet grass, snow, and slimy surfaces. Felt plus a cleated heel can be a pretty good compromise.

 

As far as we are concerned, there are only two materials to consider when buying a set of chest waders. Breathable Membranes and Neoprene. Breathable have advanced nicely since they were introduced a few years ago. They are well suited for warm weather fishing, and great if you plan to do a ton of walking in them. They can be very expensive, but prices have been coming down.

 

Neoprene is by far the best material for cold conditions. We use neoprene for all of our waterfowl hunting and early spring fishing. Neoprene chest waders can be susceptible to punctures, so you need to be very careful in them. Repair kits are available for neoprene waders and you would be wise to keep a kit on-hand when out in the field.

The Growth of UAVs and the Risks It Poses to the Public

Unmanned Aerial Vehicles (UAVs) are being used for a number of civilian and commercial purposes, from photography and videography, survey and mapping, inspections, transport to network swarming where they work together to complete a task. This article discusses some of UAV’s current commercial applications and the risk that the growth of UAVs poses on the public.

 

Agriculture and Wildlife

 

UAVs can be used to monitor many aspects of agriculture. Apart from offering an aerial inspection of the crops, they can help in inspecting soil erosion and other parameters that are hard to observe from the ground. In addition to agriculture, they can prove to be quite helpful in forestry too. They can take photos of the forests as well as the wildlife present in them to keep a steady count of the animals living in there. Moreover, they can be used to assist in putting out forest fires that may erupt from time to time.

 

Security and Law Enforcement

 

The borders as well as internal security can be very well taken care of with unmanned aerial vehicle technology. They can also play a crucial role in law enforcement too. They can be used for assisting the police in catching criminals and collecting evidence, search and rescues, surveillance and more.

 

Commercial Sector

 

UAVs may replace manned vehicles in the commercial field as some services have little need for human involvement, including transporting commodities from one place to another with ease.

 

Despite all of the promise that UAVs have shown, the commercial use of these aerial vehicles is still in its initial developmental phase. You may not see transport activities being carried out with the help of UAVs in the near future because of the risks they pose.

 

Safety Risks Related to UAV Transport

 

It is the duty of the national airspace authority to make sure that the airspace remains safe. However, unmanned aerial vehicle transport poses a great threat to airspace safety as it is extremely hard to control the drone’s flight pattern especially when it is flying into an area where various airplanes carrying passengers and goods are present. The following are some of the safety risks that may arise because of UAV transportation.

 

Air Collisions

 

The risks of air collisions increase when an airborne vehicle is not operated by a sensible and trained pilot. So, when we are talking about a UAV which isn’t controlled by any pilot, the chances of a collision happening in the air multiply greatly. While the pilot of a manned aircraft can detect the presence of vehicles flying in their vicinity and take evasive action quickly, a drone cannot make that call unless it is directed to do so from the ground. Thus, UAVs are more likely to get involved in an air collision than piloted aircraft. Unless this safety issue is resolved, the future of UAV transport looks questionable.

 

Ground Collisions

 

It is not only the collision of the UAV with other aircraft in the air that may cause great damage. They can collide with objects on the ground too, causing damage to both people and their properties. There is always a possibility of the UAV going berserk due to loss of signal from the operator or some technical fault in the system. This will pose a risk of the UAV falling from the air and crashing in a populated area. This may lead to the debris entering the houses or people getting killed as a result of the direct impact.

 

System Reliability

 

When it comes to relying on the devices and gadgets solely based on technology there is always an apprehension because of the history of failures that one has seen through the years. UAVs controlled from the ground that are operated using human intelligence can be manipulated as the on-ground pilot take decisions based on the situation. However, such systems too have been seen to crash and become the major cause of loss of lives during transport. The most common reason for accidents of this sort has been failure of various parts and machinery of the aircraft. So, when it comes to leaving decision making to machines that only operate as per pre-fed instructions, the risk of accidents increases many folds. It will take a lot of research and analysis to produce a system that is reliable in future. However, as of now the use of UAVs is still under observation and it will take many more years for them to share the airspace with manned aircraft.

 

Insurance Issues

 

Getting insurance is also an important issue as people find it extremely hard to get their UAVs insured. The main problem cited by many insurance providers is the susceptibility of the system to failure. In addition to this, the safety issues related to the UAVs is another concern why insurance companies are reluctant to insure these aerial vehicles.

 

Privacy and Security Issues

 

Privacy is a major concern associated with drone use as no one wants UAVs peeping into their homes while flying past them. Moreover, the UAVs themselves are not very safe and can be hacked any time. If a drone is hacked by terrorists then they can use it for their ulterior motives, risking the life of millions.

 

So, because of all of these issues and concerns, governments all over the world are reluctant to go forward with unmanned aerial vehicle transport for now.

The Advantages of Using an Adjustable Seatpost with Your Cycle

One of the most highly demanded and a favored product by cyclists around the world is the adjustable bicycle seatpost. In the past, cyclists relied on fixed seatposts, where the height of the seat could only be increased or decreased by adjusting the seatpost clamp through the manual operation of wrenches. But, the use of it has brought a sort of revolution in the world of cycling. Only a simple push of a remote button switch mounted around the handle that is connected by a wire enable riders to increase or decrease the height of the seat, even while riding. Also known as a dropper seatpost, the innovative product is steadily winning the hearts of cycling enthusiasts.

 

Easy to Fit in Your Cycle

 

Riders do not need to buy a new special model of cycle so as to put a new adjustable seatpost. Manufacturers commonly produce adjustable seatposts in the BMX industry standard outer diameter of 27.2mm, making it usable across several varieties of bicycles. Adjustable seatpost with outer diameters of 30.4mm, 30.9mm and 31.6mm are also widely available in the markets.

 

Unparalleled Comfort

 

Different seating positions are required for easy maneuvering of the cycles across different terrains. All cyclists must have experienced that the position which would seem to be absolutely comfortable on a straight road could be really be hard around difficult uphill or downhill terrain. But being able to control the size of the seat with an adjustable seatpost, offers riders the flexibility to comfortably navigate across different terrains.

 

Higher Efficiency and Stability While Riding

 

When the adjustable seatpost is up, pedaling becomes more efficient as cyclists can use the whole range of motion of their leg muscles. When the trail points downhill, dropping the seat allow cyclists to lower their center of gravity, in turn providing more riding stability. Thus, the rider has the freedom to choose the best seating position, based on their need to either ride faster or roll comfortably. All ‘Tour de France’ riders use adjustable seatpost with their cycles because of this very reason.

 

Different Variations Available in the Market

 

Several manufacturers currently produce different variants of adjustable bicycle seatposts based on different technologies. The most advanced as well as costly versions are operated by hydraulics. Similarly, there are also seatposts that are operated by air pressure. But the most commonly available ones are spring based variations. Hydraulics and air pressure operated seatposts require higher maintenance and are vulnerable to leaks, while spring operated versions often last longer and are easier plus cheaper to maintain.

 

Buy the Adjustable Bicycle Seatpost That Gives You the Best Value

 

Whether you are an urban rider or an adventurous mountain bike rider, seek the dropper seatpost that provides you the best value. Choose a product that is comfortable to use but isn’t too expensive to buy and maintain either. Spring operated versions could be one of the better choices. However, in case of heavy duty mountain bike riding getting a hydraulic version can be worth it as well.

What Are the Different Types of Metal-working Machinery?

Metal-working machinery includes a wide variety of equipment used to cut and shape metal. These machines offer an alternative to shaping these metals by hand, resulting in greater precision and higher production levels. They can be found in many metalworking shops, manufacturing and industrial facilities throughout the world, as well as in the homes of hobbyists. Metalworking machines come in many forms, including lathes, milling machines, and planers. This equipment also includes basic tools used to modify the surface or finish of metal, including grinders, polishing equipment, and embossing machines.

 

Lathes are one of the most widely used types of metal-working machinery. These devices rotate a metal object around a spindle. As it rotates, tools and cutting bits shape or cut the metal into the desired form. These machines can range from small desk-top units to large floor models. While some may be manually operated, most rely on computer programming using computer numerical control (CNC) software.

 

The milling machine can be thought of as a more advanced version of the lathe. This metal-working machinery holds an object in place as the worktable moves around it. Unlike the lathe, milling machines can modify metal across three dimensions, not just two. Micro milling machines can even be used to cut and shape items that are invisible to the naked eye. Like a lathe, milling equipment generally relies on CNC software for precise control and programming.

 

A metal planer can be used to cut or shave metal in a single linear direction. These machines hold the metal object stationary, and then run a cutting blade across the surface to smooth or flatten the material. Planers can also be used to cut slots or other shapes into the face of a product.

 

Metal-working machines can also include equipment used to bend and shape sheet metal. For example, a metal brake creates folds or bends in sheets of steel and other metals. Similar machines are used to stamp or emboss patterns into metal, or to roll it flat. These machines can be either manually operated or controlled using a CNC system depending on where they are used.

 

Extruding and casting equipment are other types of metal-working machinery. In casting, workers make a mold of an object and use it to shape molten metal. Extrusion involves forcing hot metal through a die. The shape of the die determines the shape and profile of the final product.

 

SEHO provides much different second hand metal-working machinery such as CNC grinding machinery etc. machine tools. If you are interested in learning more information about used machinery, welcome to visit our website and feel free to contact with SEHO Industry Co., Ltd.

Glass Fibers and Fiberglass Fabrics Information

Glass fibers and fiberglass fabric consist of bulk, chopped fibers or continuous strands of glass. Glass fibers and fiberglass fabric is used in reinforcing plastics and composites as well as other specialized electrical and thermal applications. Fiberglass cloth is frequently used to reinforce other plastic materials. Glass fiber reinforced plastic (GRP) or glass fiber reinforced epoxy (GRE) are commonly called fiberglass.

 

The glass fiber used to create fiberglass material is made by extruding very thin strands of silica-based monofilament. Glass is a unique amorphous solid, meaning it doesn’t have an underlying crystalline structure in the solid state, but rather behaves like a very viscous liquid. Glass fiber lends itself to woven fabric because the thin fibers can easily bend. Fabric made of glass fibers has high tensile strength, dimensional stability, high heat and fire resistance, as well as resistance to many chemical compounds. Fiberglass fabric is also used to dissipate heat, and has electrical properties that make it useful in electronic components.

 

Applications

Glass fibers and fiberglass fabrics are commonly used in composite construction, including materials used in boat building. Light weight fiberglass cloth is used with a resin to produce a waterproof surface. Heavier woven fiberglass fabric can be used for greater strength and rigidity.

 

Glass fibers and fiberglass fabrics are also used to create combination or specialty fabrics. Glass fibers and fiberglass fabric may be combined with carbon fiber or aramid fibers to make laminates and moldable fabrics for canoes, kayaks, and other high strength, low weight applications.

 

Standards

Glass fibers and fiberglass fabrics must adhere to certain standards and specifications to ensure proper design and functionality.

 

Delphi DX300340 – This specification covers the properties of a Polyamide 6, 40% glass filled, impact resistance modified injection molding grade used for the manufacture of parts that require high stiffness and toughness under extreme conditions (Example: airbag containers).

 

GMW15890 – This specification covers the properties of polypropylene reinforced with long glass fibers. It covers injection molding types for manufacturing of technical parts requiring high structural stiffness.

 

JIS C 6832 – This standard specifies the dimensions, transmission requirements, mechanical requirements, environmental requirements and the test methods of silica glass multimode optical fibers using silica glass as a core and a cladding.

 

Taiwan Electric Insulator Co. Ltd. is a world leading manufacturer of fiberglass fabrics and composite materials, with the technology, knowledge and ability to produce the highest grade composite material to specific customers’ needs and requirements.
