As a high-precision machine tool equipment, CNC vertical lathe's processing accuracy and stability are crucial to industrial manufacturing. In the maintenance and upkeep of CNC vertical lathes, scraping and grinding is a very important task. So, why do scraping? What is scraping?

First, let’s take a look at scraping. Scratching is a processing method that uses manual or mechanical methods to make two contact surfaces smoother and more detailed to improve their matching accuracy and friction reduction. In CNC vertical lathes, scraping is mainly used on the mating surfaces of shafts and holes, such as spindle journals, spindle box holes, etc.

Why scrape? Mainly because during long-term use of CNC vertical lathes, the contact surfaces of each component will become uneven due to wear, fatigue and other reasons, which will lead to a decrease in movement accuracy and affect the stability of the equipment. By scraping and grinding, we can repair the damage to these contact surfaces and improve their matching accuracy and movement accuracy, thereby restoring the equipment to its original performance.

The principle of scraping is mainly based on the adjustment of surface micro-geometry. Through fine scraping, we can remove high spots and bumps on the surface, making the contact surface smoother. At the same time, the cold work hardened layer produced during the scraping and grinding process can improve the hardness and wear resistance of the surface, further enhancing the durability of the equipment.

In general, scraping and grinding are an indispensable part of CNC vertical lathe maintenance. Regular scraping and grinding can ensure the stability and accuracy of the equipment and extend the service life of the equipment. For operators, understanding the principles and necessity of scraping will help them better maintain and use CNC vertical lathes and ensure efficient and stable production.
