How to maintenance and proper use of Cast iron surface plates?
Many factors, for example, temperature, humidity, vibration, etc., will affect the flatness precision of the Cast iron surface plates in some extent, so it’s very important to control the environmental aspects. But in order to get the higher precision in the daily using, you should pay more attention to the maintenance and proper use. The improper use will lead to an error measuring result. The insufficient maintenance will lower the surface precision. Even worse, the quality of the inspected products will be affected accordingly. Thus, we need to follow the below items when using and maintaining the Cast iron surface plates.
1) Before the inspection, to be sure the surface precision is in the acceptable range. And check the surface of the cast iron surface plate to see whether there is any corrosion, abrasion, scratch, dusty, and the like. It’s very important of using the soft cloth or dust-free paper to wipe the surface. One more, the surface plate should be placed in proper position, overlap each other is not allowed.
2) When measuring, the cast iron surface plate should be properly contacted with the workpiece. Protect the cast iron surface; do not use your hands to touch the measuring surface. In the process of measuring, the force must be proper, too large will lead to an error measuring result, and the cast iron surface will be damaged also. Measuring the special shaped workpieces is allowed, but you need to follow the relevant steps.
3) After finishing your inspection, the first step you should to do is cleaning the surface plate; then coating it with anti-rust oil, placing it into the cabinet. Dismantling, debugging, revising and assembly should be carried out by the professional staff. Check the performance of the stored cast iron surface plate and verify whether the surface plate is qualified, make the record accordingly.
