Description

Technical Field

[0001] This invention relates to the field of metal cutting machine tool technology, and in particular to a roll grinding debugging system and debugging method. Background Technology

[0002] Rolls are shaft-type parts. Currently, the grinding of rolls in the industry generally adopts MDI (manual data input) single-stage grinding, which has a low degree of automation, long auxiliary time, and requires repeated tool setting, manual grinding wheel repair, manual program modification, and manual input of various parameters. During the grinding process, the operator needs to measure the dimensions of the machined part multiple times and manually input the degree compensation and feed rate. The process is cumbersome, the processing is discontinuous, and a lot of time is wasted. The level of automation in the grinding process is low, and continuous processing of all steps has not been achieved. Continuous operation of the grinding process urgently needs to be improved.

[0003] By designing a roll grinding and adjustment system, the number of tool setting and parameter input steps can be reduced, enabling automatic tool setting and automatic grinding wheel dressing. This reduces manual operation during the grinding process and improves the level of continuous and automated grinding. Simultaneously, automation can avoid unsafe factors during grinding wheel setting, improving operational safety, reducing human contact with the rolls and cutting fluid, and improving the working environment for grinding operators. Summary of the Invention
