What is a Turret Type CNC Lathe?

Posted on by

Read this article to know more about a unique type of lathe machine which can be used for mass production either using modern CNC technology or older mechanical system controls.

 

Introduction

We have been talking quite a lot about various types of machines used in industry in general as well as those used specifically in manufacturing technology including lathe machines. In this article we will focus on a particular type of lathe namely the turret type CNC lathe and learn about its working and uses it can be put to.

 

What is a Turret Type CNC Lathe?

As we learnt earlier, a lathe can be used for various purposes including woodcutting, metal-cutting, watch-making and what not. The basic purpose of all these machines is to minimize human labour involved in the process and make it as much automated and refined as possible. Lathes which are used for metal cutting in industrial processes are normally required to produce products on a mass scale.

 

A single product requires several machining operations which in turn would require several different kinds of tools to carry out these operations. If an operator were to manually adjust each tool after every single operation, this would certainly consume a lot of time and unnecessary efforts.

 

Keeping the above limitations in mind the engineers came up with the idea of a typical lathe machine where everything could be fitted and configured in one go literally speaking. Such a metal working lathe which has got a turret and can perform several functions in an automated fashion is known as a turret lathe.

 

How does it function?

It is all very well to say that the processes are automated but how do we go about achieving the same? Well the answer varies depending on the nature of lathe we are talking about. For example modern CNC lathes use servo-mechanisms to control and time all these processes while in the older versions mechanical arrangements such as stop limits etc. are used to achieve the same goal.

 

About the turret

If you are aware of gun related terminology you surely would know that a turret refers to a sort of arrangement which his used to hold several weapons which can fire the particular shot depending on exact requirement. The turret of the lathe is a similar platform in the form of a tool holder, which holds various tools which can be used by appropriate rotation depending on the requirement of the work piece in a specific order which is preset using whichever method is used to control the automation.

Plastic Badge Holders – How to Choose the Best Style for Your Needs

Posted on by

When considering the size, you want to make sure the holder is not too bulky for continuous wear. If a larger holder is needed for brochures, leaflets and things of that nature, consider partnering it with a lanyard so it can be worn around the neck preventing the holder from weighing down the event goers clothing. If the plastic badge holder is to be worn daily, you will likely not want to go any larger than 3″x4″ for ease of movement. Many business card size holders are available which is a great size for wearing on a daily basis.

 

Plastic Badge holders also come in a variety of thicknesses of vinyl. 10 gauges is a common thickness that you will find in most badge holder styles. This thickness is suitable for limited or occasional use. 10 gauge holders should hold up well for the duration of an event or meeting. If you are looking for a holder to be used daily or that will experience harsher wear and tear, consider a heavy duty style with a thickness of 30 gauge or higher. You may also consider acetate material or rigid holders for high use environments.

 

When choosing your fastener type, you will need to consider your employees and/or guests. Keep in mind what will be most comfortable and practical for the use of the holders. A standard pin is common and generally is the least expensive option. Pins are secure to the clothing, however, they can sometimes cause damage with pin holes or possible ripping if the holder is caught on something. Bulldog clips are another option. Clips are a great alternative to prevent damage to clothing, but you do need to ensure uniforms will have an appropriate place for attachment such as a pocket or collar.

 

You can also find badge holder styles referred to as “combo” which include both a clip and a pin. This gives your event goer an option to choose which fastener they prefer to wear. A most popular option is to attach the badge holders to the end of a lanyard. Lanyards are worn around the neck eliminating the attachment of the holder itself to the clothing. Lanyards are generally offered with key ring, bulldog clip, or swivel hook fasteners. Most badge holders come with either an oval slot and/ or a circle in the top for fastener attachment. Bulldog clips work perfectly with most oval slots while swivel hooks are a better option for circle holes. Key rings can be used for either style, however, they are a bit more time consuming to attach. You can also find badge holders that have an elastic style lanyard already attached to the lanyard on each end. These are an easy and convenient option because there is no need for assembly.

 

Many plastic badge holders are offered blank without customization which are great for a quick turnaround and are certainly more cost effective. Customization is often offered on a variety of sizes. You may want to consider customizing with text and color for easier identification at your trade show, meeting, or even your workplace. “Exhibitor” and “Attendee” are popular titles that are used for customization of your plastic badge holder. You may also choose to include your company name and/ or logo. Choosing to add customization adds a special touch and importance to your badge holders while also making your guests more easily recognizable.

Plastic Recycling Process and Plastic Recycling Machinery

Posted on by

Thermal depolymerization, polymer plastic. The use of the plastic is increasing now a day like water is coming in the plastic bottle and the colas are also coming in the plastic bottles. Both of the different types of drink use in a huge amount by the people and it is not only using in some countries but the usage of the plastic bottle is in huge amount in each and every country. After drinking the material from the bottle most the people throw it in the bin as they consider the empty plastic bottle as the waste.

 

The recycling of every type of the plastic is necessary because the plastic which is empty and which has no use in the world and pollute the environment in one and the other way. If the empty plastic bottle will not recycled and it if burn then by the plastic the carbon will evolved in the air which pollute the environment and is also dangerous for the human being living near the area in which this type of activity is going on. The plastic recycling can save the environment and it also effect on the consumption and making the new plastics.

 

It is also not necessarily important that if the bottle of the plastic is recycled then after the process the recycled plastic will not use in making the same type of the commodity again. Once the plastic is recycled the is melted it can be used in making the different commodities like the plastic of the pet bottle is recycled then the chair of the plastic can be made through that re cycled plastic. Recycling is important because it also affect the cleanliness of the city. Especially the recycling of the pet plastic bottle is more important as the pet bottles after consumed is throw in the waste and is seen in the third world countries that the bottle made of the plastic can be found on the ground.

 

One of the challenge faced in recycling of the plastic is that as compare to the glass the recycling of the plastic need long process and so it require the time and the plastic recycling machinery rather that it is the fact that after the recycling of the plastic it is more useful than the glass or any other thing with which the same things can made. The structure of the plastic bottles are very intense type of the structure as it is made up of the polymer plastic so that the heating is not enough to melt the plastic it need more process than simple heating the bottle in the machine like one again the example of the glass is consider.

 

As there are many type of the plastic so that before the plastic goes in the recycling it should be categories. The plastic is categories on the level of the polymer used in making the plastic. The process in recycling is monomer recycling then thermal depolymerization and last step is heat compression.

DC Electrical Motors for Cars

Posted on by

Electric cars are rechargeable vehicles powered by electric motors. Electric motors for cars convert electrical energy into mechanical energy. Controllers regulate and control power received from rechargeable batteries to run the motors. The motors could be AC or DC motors. DC motors for electric cars could be further classified as permanent magnet, brushless, and shunt, series and separately excited. The DC uses electricity and a magnetic field to produce torque, which rotates the motor. The simplest DC electrical motor comprises of two magnets of opposite polarity and an electric coil forming an electromagnet. The properties of attraction and repulsion are used by the DC electrical motor to convert electricity into motion — opposing electromagnetic forces of magnets generate torque causing the DC motor to turn. Characteristics desirable of electric motors for cars include peak power, ruggedness, high torque-to-inertia, high peak torque, high speed, low noise, minimal maintenance and ease of use. Current generation electric motors are combined with inverters and controllers for a wide range of torque.

 

The abundance of series DC motor has allowed it to be tested on a variety of vehicles. The Series DC are robust and long-lasting, and the power density provides the best value for money. The torque curve suits a variety of traction applications. However, it is not as efficient as the AC Induction motor. The commutator brushes wear out and maintenance activities are required periodically. It is also not suitable for regenerative braking, that allow vehicles capture kinetic energy to recharge batteries.

 

DC motors are simpler and cost less, and have been widely used in demonstration electric vehicles. Brushless DC has no commutators, and is more powerful and efficient than commutator motors. Such DC motors, however, require more sophisticated controllers. Brushless DC in electric cars can give efficiencies up to 90%, and no servicing is required for up to hundred thousand kilometers. Experts at Floyd Associates (2012) argue that electric cars with DC Brushless motors can achieve the highest speed but slowest acceleration; AC Induction can achieve the fastest acceleration with average top speed; Permanent Magnet motors can achieve top speed and average acceleration; and Switched Reluctance motors provide the most cost-effective solution.

How to Succeed with Smart EDM Operation

Posted on by

The benefits of EDM have become clear to many mold manufacturers throughout the past several years. It allows for the super-precise machining of delicate, complex parts and hard-to-machine materials, and eliminates downstream operations such as polishing and deburring. Still, some moldmakers may not be getting the most from their EDMs. Several factors can contribute to the success of EDM or be detrimental to the process.

 

Choosing the Right Machine

First and foremost, machine selection is a huge part of operational efficiency in EDM. Depending on the application, moldmakers can choose from wire, drilling, sinker or some combination of the three.

 

  • Wire EDM:

Choose a machine with the latest cost-saving features. For example, some machines have an operational mode that minimizes wire consumption by slowing down the wire feed. The right wire EDM can also help manufacturers save on energy and consumables, with features that control and optimize dielectric fluid volume and pressure, pump and filter operation, and resin consumption.

 

  • Drilling EDM:

Moldmakers should look for machines that combat hole tapering—otherwise known as bullet nosing. To avoid this common problem, machines must not only use high-quality electrodes, but also feature a power supply with a low unload voltage—ideally less than 35 volts. This maintains a high speed, but reduces wear and tear on electrodes. The right type of dielectric fluid can also combat bullet nosing. Try tap water with the appropriate additives instead of de-ionized water.

 

These are ideal for cavity and rib machining, and as with wire EDM, selecting the correct machine is the key to productivity. Features such as c-axis, lateral servo, high-speed jump and state-of-the-art power-supply technology can reduce electrode wear and improve productivity. CNC sinkers with high-speed spindles can also perform the same job as an EDM drilling machine, but at a much smaller hole diameter and with more precision.

 

When it comes to purchasing any type of EDM, remember to consider its control technology. Many machines now have sophisticated software that incorporates 3-D modeling, which can significantly improve ease-of-use and operator efficiency.

 

Maintaining EDM Performance

Proper preventative maintenance is crucial in keeping EDM machines running as efficiently and economically as possible. Operators need to check and maintain consumables—such as power feeders, filters and resin—regularly to prevent unstable, inaccurate machining.

 

Cleanliness can also affect an EDM’s performance. Contaminants such as sludge, dirt and spray from dielectric fluid as well as burrs can compromise filter life, cause corrosion and reduce overall accuracy. Check and clean the worktable, lower arm and head, seal plate, conductivity sensor, fan cooler, filter pump and auto-threader to maintain peak performance. Also be sure to keep the machine well lubricated.

 

Check the power feed and ground cables regularly. Problems with them are the number-one cause of speed loss in EDM machines. The wire transport system, rollers, bearings and flush cups are other elements of the machine that are often the culprit of faulty performance.

 

Summary

With the pressures to compete on a bigger and more global scale, moldmakers have been forced to do more with less. Increasing productivity while lowering costs is a goal on every mold manufacturer’s list. Fortunately, the opportunities to succeed and grow with new EDM technologies—and several tried-and-true best practices—have never been greater.
