Milling Machine Types and Uses

Posted on by

Milling machines are used mainly for shaping and cutting solid materials such as metal, wood, plastics or even brass. These machines differ from a lathe in that the tool head itself rotates at high speed whereas with a lathe the part itself that is being worked on rotates. This sort of machinery varies greatly in terms of cost and in the specifications of the machine. Hobby machines will obviously be a lot more cost effective than their industrial counterparts.

 

So we will be a taking a look at some of the milling machine features and some of the important things to consider when looking to buy a machine for home or industrial use.

 

Types of Milling Machine

 

Found more often than any is the column type of machine. It has a few basic parts and is pretty simple. Materials can be drilled by means of the vertically suspended cutting device.

 

The turret mill is a more versatile option than the column machine. It is capable of producing many types of products as the spindle can be aligned in many different positions.

 

The C-frame is more usual to be found in an industrial workplace. It is tremendously powerful to cope with larger milling jobs.

 

Horizontal and Vertical Mills

 

These two types of machine are fairly similar, the main difference is the vertical machine’s spindle has a vertical orientation as the name suggests. It’s good for plunge drilling and cutting.

 

A horizontal mill has the cutter or cutters located on an arbor. This type of machine is good for heavy cutting like slots and groves for instance.

 

Digitally Controlled

 

The CNC (computer numerical control) machine or sometimes referred to as machining center is a highly accurate form of milling. The machine is set up usually via computer aided design technology. This sort of control allows the part to be engineered to a high level of complexity such as engraved elements and relief. The precision achieved is unsurpassed and with little operator input needed following the set up phase and the production of the test piece it’s also cost effective.

 

Important Considerations for Purchase

 

It will depend an enormous amount on what the machine is required to do of course. So it’s important to look at the complexity of the work to be done and consider the number of axis variants required. The power of the machine will also be important as will the speed that it operates at. As some milling machines will come with various attachments others will require these at additional cost. The overall cost may be important and some really good used milling machines can be found online if needed.

 

So I have taken a look at some of the milling machine types and their uses along with what sort of things to look out for when considering the right one to get.

About CNC Lathe

Posted on by

A CNC lathe is a machine that can spins material to do a variety of operations like sanding, drilling, cutting or sanding. Usually a lathe is used for more intricate cuts and Today, they replace the older multispindle lathes because they are easier to set up and operate.

 

A CNC lathe will use carbide tooling and is designed using a CAM process which creates a file that can be uploaded to the machine at a later time. The reason these are so popular is because you can set the machine once to do several pieces and it will continue to do them until you have programmed it to stop.

 

Each CNC lathe has a computer control that allows the machine to be controlled electronically, and this program can be modified to do a variety of things. When an operator runs a CNC lathe they have to have a lot of skill to understand the programs and how the programs to do the work.

 

You can work with wood when you use a CNC wood lathe or various metals depending on the project you are doing. The wood lathe can be used for wood but also for brass and Aluminum. There are also metalworking CNC lathes or milling machines that cut metal. You can do tapered work with these, drill holes, and create screw threads and more with these lathes.

 

Some CNC lathes are portable and others are stationary. In many shops for people who do woodwork for a hobby you would find a lathe because it is capable of making a lot of different designs and intricate cuts for things like stair railings, trellis’ or table legs.

 

The point of using a CNC lathe is to make a piece of material that is symmetrical and beautiful. This is done by placing the material in a machine and allowing that piece to be spun until it reaches the specification that was programmed into the computer. The cutting tools then move around it on the Z and X axis to cut away the material that isn’t needed to make the piece.

 

The process that the CNC lathe does is called turning and it can do a variety of shapes when it goes through the full process. Many machines are used to create a plain surface to make contour shapes, to taper the ends of some pieces and it makes threaded surfaces. You can also turn metal so that you can create rods bushes, pulleys or other shapes that are needed. In some industries they use a CNC lathe to fabricate parts that may have a cross section that is to move in a circular motion.

 

Any material can be used as long as it will hold up during the turning process while the software program is continuing its revolutions.

 

CNC lathes are best used when you want to turn out several pieces of the same size and shape and where you don’t want a lot of decoration. They do have their limitations but for the most part you can create nice pieces with this type of machine.

Mill+Drill=Milling Drilling Machine

Posted on by

The milling drilling machine is an alternative to a milling machine. These combine a belt driven drill press with the dual coordinate abilities of the milling machine’s table for flexibility and efficiency.

The following discussion guides on advantages of drilling machines and milling machines:

 

Drilling machines are fixed style drills that can either be mounted on a stand or bolted to the floor or workbench. The speed can be changed on these machines by manually moving a belt across a pulley arrangement.

 

Drilling machines can offer its users many advantages. Firstly, the lever gives the operator a considerable mechanical advantage. As it is fixed to a table, this allows a vice or clamp to be used to position and secure the work piece making the operation much more precise. In addition to this, the angle of the spindle is fixed relative to the table, allowing holes to be drilled accurately and repetitively.

 

Most modern machines are technically automated with the use of computer numerical control (CNC) technology. Because of this they can be programmed to produce precise results, continuously. In particular, CNC drilling machines are useful for pattern hole drilling, small hole drilling and angled holes. Drilling machines are frequently used for random workshop tasks such as sanding, honing or polishing, and a variety of other rotating accessories in the chuck.

 

Milling machines differ to drilling machines in a variety of ways. These machines are used for reshaping metal and other solid materials. Milling machines come in two varieties, either horizontal or vertical. This refers to the position of the cutting tool spindle. Unlike drilling where the piece is stationary and the drill moves vertically onto the material, milling also involves movement of the work piece against the rotating cutter.

 

In a similar way to drilling machines, milling machines may be manually operated, mechanically automated, or digitally automated CNC. Milling machines can be used to carry out a number of tasks. Some of these are quite complex, for example, drilling, die sinking, rebating, routing, etc.

 

As with drilling machines, many modern milling machines are controlled by a computer. This provides them with more flexibility. When this is combined with the appropriate accessories; conical tools or a ball nose cutter, it can dramatically improve its precision with no impact on speed, providing a cost-efficient alternative to most flat-surface hand-engraving work.

 

Previously, these types of machines were very expensive to buy and operate but with the drop in the price of computer technology it has made them much more affordable and accessible. This has allowed more businesses to take advantage of this technology, improving competition in the industry.

 

Rong Fu is a manufacturer of milling drilling machines in Taiwan. The milling drilling machines are an alternative to a milling machine. These combine a belt driven drill press with the dual coordinate abilities of the milling machine’s table for flexibility and efficiency. A locking collet prevents the cutting tool from falling away from the spindle when lateral forces are experienced against the bit.

 

The Rong Fu Milling Drilling Machines combine the advantage of space-saving versatility with features you’ve come to expect. All milling drilling machines are manufactured to meet the highest level of customer requirements. Welcome to visit Rong Fu’s website to get more information about milling drilling machines!

Something Must Know Before Working With an LED Manufacturer

Posted on by

Any project, large or small, can benefit from the experience and knowledge of a professional. LED lighting is no exception. Whether you work in health care, industrial, commercial or an educational or government setting, or you just want to brighten up your home with fresh, clean energy – getting to know the right LED manufacturer can make a serious difference in the way you view your “space” as well as how much money and energy you can save.

 

Perhaps the most important benefit of switching to LED technology is the inherent advantages you’ll see immediately from making the change. LED bulbs burn cleaner and last longer – up to 50,000 hours without ever burning out. Even after such prolonged use, they still give off up to 70% of their original light. Compare that to a burst from a burnt out incandescent light or a flickering fluorescent light and you’ll see that using LED lights can considerably free up your time and costs that you’d ordinarily have to spend on maintenance.

 

The right LED manufacturers will also work with you to help you find the right LED bulbs and products for your needs. Whether you’re looking to install solar LED lamps or you’d like to experiment with LED light colors in your home or office, a reputable LED supplier can assist you in making the right decisions. Depending on where you live, you may even qualify for funding or incentives to help you purchase LED technology for use in your project. Government and statewide programs are available to help ease the financial and engineering issues that go along with making the transition to new lighting technology.

 

But the benefits you’ll see as a result of moving toward LED lighting produced by a reputable LED manufacturer far outweigh the costs. In addition to using 90% of their energy to provide light (and only 10% for heat), LED bulbs are cost efficient energy savers. Many people report that using LED technology has resulted in up to a 50% savings or more in their monthly energy bill. This, combined with less maintenance and higher safety (LED lights contain no hazardous chemicals or metals) showcases that new advances in technology truly are worth the change. If decreasing energy use is high on your list of must-haves, you’ll be glad to know that many LED products include programmable dimming or time-related switches which minimize wasteful use and make sure the lights last even longer.

 

Be sure when working with an LED manufacturer to ask to see their portfolio of projects and the costs and savings associated with them. Good LED suppliers will be able to showcase examples where their products have been used in the home and office areas as well as in hospitals, schools, retail and other locations. By working with a reputable LED manufacturer who carries only fully certified products that meet or exceed lighting and energy savings standards, you’ll find that you’re taking a significant step toward helping create a cleaner, greener environment with energy that’s low-maintenance and money saving while adding beauty to any room or area.

Purpose and Features of PVC Valves

Posted on by

Over the decades, polyvinyl chloride (PVC) valves have penetrated both commercial and domestic domains. PVC valves made with suitable additives provide the desired physical and chemical compatibility. Although they have limited use in high temperature applications, advances in PVC technology have enabled manufacturing of the valves with reasonable tolerance to medium range temperatures. In a similarity with their metal counterparts, plastic valves are machined using similar CNC machining centers and lathes, however the parts of the PVC valves are joined using threaded joints or cement or fastened using fasteners. They can be installed with very little additional help from wrenches.

 

Purpose of PVC valves:

 

One of the most common reasons for the failure of conventional metal-based valves is corrosion. Corrosion affects industries such as chemical processing, nuclear power generation, onshore and offshore oil and gas, underground pipeline, water treatment, sewage handling and treatment, highway maintenance, aviation, and metalwork. Moreover, options for a corrective action or a preventive action are limited. Pervasive nature of corrosion in certain industries made them look for alternative options such as PVC valves as they were virtually unaffected by corrosive atmosphere. Furthermore, smooth surfaces are resistant to scaling and allow better flow rates, while external surfaces require no additional coating to protect the shell from environmental damage. PVC valve avert any organic growth, making it suitable for ultra-pure applications such as semiconductor fabrication and manufacturing of polymers. Servicing of the plastic valves is relatively easier since no special tools or tackles are required to disassemble the valves and allows on-site servicing requiring minimal downtime. These features made it desirable in some industries.

 

Features of PVC valves:

 

As discussed earlier, PVC valves offer non-corrosive, non-contaminating, and smooth surface for process fluids. Apart from these properties, they are lighter in weight than metal valves of similar sizes. The PVC valves offer resistance to acid along with corrosion and they repel any formation of scale on the surface because of their smoothness. In comparison with metal valves, integration with plastic pipes and fixtures are easier with PVC valves. According to the life cycle assessment of PVC commissioned by the European Commission, the average lifecycle of PVC water pipes range anywhere between 40 and 80 years and thereby a conservative estimate of the PVC valves’ life cycle is close to 10-20 years. This compares favorably to other alternatives because of their use of lesser non-renewable resources i.e. 57% of PVC is derived from salt and the remaining 43% is obtained from oil/gas. Most of the PVC valves can handle pressure of up to 150 lbs./sq.in, which is lower for most piping sizes in the schedule 80 threaded piping system. Due to presence of more than fifty percent chlorine in the PVC, PVC valves are fire-resistant. Even when the valves are burned, they emit hydrogen chloride gas that prevents oxygen from reaching the surface and thereby prevents faster reaction. The valves offer excellent chemical compatibility with salts, alkalis, oxidizing agents, and acids. In addition, they offer reasonable compatibility with organic solvents. Since PVC has easy processing characteristics, the desired specification for the valves can be achieved. PVC valves are relatively more cost effective than metal valves due low weight and lower price of base material. These valves are also highly resistant to ultra violet rays, which makes them suitable for UV sensitive applications such as photographic material. Their no-reaction characteristic with most organic and non-organic material makes them suitable for handling medical and bodily fluids.

 

Conclusion:

 

The PVC valves have penetrated both the domestic and commercial market due to their performance characteristics and advantages they offer over the valves made out of other materials.
