Plasma Cutting Table: Considerations for Smooth Motion

A plasma cutting table and system are very popular because of their ability to produce cuts that consistent and quality without causing damage or warping around the material. However, the quality of its cutting torch is as good as all the other supporting components.

A plasma cutter mainly relies on smooth motion in order to cut properly. Any form of hiccup in the movement that is caused by debris or vibration can throw a cut off. As a result, it causes the business to have interruption in their processes and incur costs. This is why as much as possible, errors should be avoided. One best way to do this is to select a plasma cutter that comes with a high-quality hardware to provide the needed smooth motion. There are several components to be considered to achieve this smooth motion such as the following.

 

Type and Quality of Bearings

The use of bearings in a plasma cutting system is to let the gantry to smoothly move in the X, Y, and Z directions. Any disturbances and vibrations will be prevented with smooth motions and this will ensure that the motion in cutting will stay consistent.

The bearings you choose can make a huge different on the overall operation of the device. Top models are likely to choose grooved bearings that run on an interior rail. Such type of bearings is very useful as they can help sweep debris and dust off the machine automatically, thus negating the need for cleaning. This makes the cutter suitable for dusty environments.

 

Rail Quality

Translating the instructions from your computer to mechanical movements depends on how accurate the construction of the system is. The overhead gantry and rails should be perfectly straight so they provide a reliable and real-world representation of the coordinate system of the computer design. In the event that the tracks are off even by just a fraction degree, the plasma cutter would not accurately recreate the design.

Rails that are high-quality should be made from a single piece of an extruded material. Its trueness could be checked with the use of a laser guide or some other implements. High quality ones would allow the gantry to freely move along the length of the table, thus allowing sharp cutting motion.

 

Gearing System

A plasma cutting table uses gearing mechanisms that convert energy from a motor into useful motion for the gantry. With this, the action of the torch head becomes dependent on the quality of the gearing system. The majority of the systems on plasma cutters uses a combination of metal gear rings and steel-reinforced plastic drive belts.

 

Feedback System

A motor on each axis controls the movement of the cutting torch. The motors along with feedback devices provide the computer with information on far the cutting head need to move. The lower latencies help the cutting table to offer a smooth and fast motion, especially when making cuts in different dimensions or cutting tight corners.
