Work holding is a critical part of manufacturing. Being able to hold the piece in place for concise process can be challenging without the right equipment. This is why most people and businesses are looking to magnetic chucks to solve the problem. There are quite a number of different options that are available in the market and you need to make sure that you have the right one. Here are the five most common and what you can do with them.
- Permanent Rotary magnetic chucks
If you have worked with rectangular chucks, these have the same functionality. They are built with poles that run off to the edge and the top plates are built out of brazing magnetic steel and non-magnetic stainless steel. In cases where the permanent rotary magnetic chucks have to be used in high torque demanding applications, screws or dowel pins can help for better support. There are accessories like the auxiliary plate that makes this magnetic chuck usable for other applications like lathe cutting or grinding.
- Rectangular magnetic chucks
These have two main assignments in the production line; holding capability and providing high performance work. They work in the same way that circular magnetic chucks work and feature brass and steel top plates for better coolant resistance. To enhance work holding and easy release, the rectangular magnetic chucks feature ceramic magnetic chucks.
They come in two different sizes each of them best suited for different applications. The fine pole chuck is best for thin workpieces and the standard pole is ideal for thicker workpieces.
- Pole Chucks
There are two types of pole chucks. There is the longitudinal pole chuck that has the poles running the length of the chuck from one end to the next. The top plates on these chucks are furnace brazed which makes the nonmagnetic and magnetic steel one water tight unit.
On the other hand there is the transverse pole chuck. In this case the poles run across the chuck from side to side. The spacing of the poles varies from one chuck to the next. The smaller the space the lesser the chuck and the reverse is correct for the bigger chucks.
- Electro permanent magnetic chucks
With all the benefits that permanent magnetic chucks have to offer, these types of chucks also bring with them the benefits that are attached to any electro-magnet. They consist of an electronic on and off switch which helps to minimize the build-up of heat and distortion of parts. They also have an increment variable hold and a demagnetization cycle. These are best used for grinding large or small work pieces and can also be used for medium and light duty milling.
Picking the right magnetic chuck is essential. Each of them is built to take on certain challenges and excel. Depending on the size of the workpiece that you will be handling and the process that you would like to complete, it is important that you ensure that you have the best chuck for the job for the best results. It is also important to note that with the right pairing, each of them will have unique benefits and the ultimate goal of a safer environment for you.
