Description

Technical Field

[0001] The utility model relates to a milling cutter free-space-avoiding grinding machine. Background Art

[0002] Currently, tool manufacturers sell standard cutting tools. However, in some parts processing, the blade length of standard cutting tools cannot meet the actual processing requirements. A black mark appears when machining sidewall features. This problem occurs because the machining depth of the sidewall is greater than the length of the standard milling cutter blade, causing friction between the tool shank and the sidewall. Customizing cutting tools is time-consuming, labor-intensive, and expensive. Generally, operators use ordinary tool sharpeners to grind a clearance gap between the blade and the tool shank to solve the problem of sharpening the tool shank. During sharpening, the operator needs to manually measure the depth and width of the clearance gap multiple times, and then decide whether to continue sharpening based on the measurement results. The sharpening efficiency is very low, and it is necessary to solve this problem. Utility Model Content
