When it comes to CNC machining, every shop needs to apply the right principles during the production process so that the parts get machined to the best shape and size to meet the tolerances. It can be easy to mark out centimetres or even millimetres. However, many times, the tolerance for CNC machined parts are less than 0.001 of an inch. When these measurements are so small, you should have the right tools and know how to use them properly. The tools that a shop uses for CNC metal machining might vary depending on the quantity of work done, but the right tools can determine the shop’s overall capabilities.
This item is a flat surface that the machine can use for Y-axis, or vertical, measurements. They are useful only if they have the right calibration and keep their shape properly. Since they have a low level of expansion with temperature changes and a smooth surface, many surface plates are of granite.
This tool can measure your parts to make sure that they meet the specific tolerance. The “no-go” part of the tool measures one part of the tolerance range, and the “go” is for the other. For example, if you have a plug gauge, the “go” end fits in a hole and the other end does not.
These can range quite a bit in their sophistication, shape, and size. No matter what type you have, they use the same principle to measure. They allow the opposing tips to rest at the end and beginning of a distance you are measuring. One example of this is the common protractor, which measures degrees.
In the 1600s, Vernier callipers were first perfected, and they are a flat bar with two opposing, sliding tips. The distance between the tips can accurately get measured with a graded scale.
This tool for CNC machining in Toronto uses a calibrated screw attached to a scale that can move as you turn the screw counterclockwise or clockwise. Many of these tools function and look like callipers do, but you can get these in many different shapes.
