What knives need resharpening?
Most of the tools can be regrinded, and the subsequent tool regrinding is taken into account in the production design; of course, on this basis, the overall cost and benefit should also be considered in the tool regrinding; relatively speaking, for most Tools with relatively high cost can be scrapped directly and give up grinding, because the added value itself is not high; for some forming tools, because the size will be too small after grinding, it will affect the use, so grinding cannot be done; when some When standard-diameter taps, milling cutters, and drills need to be repaired, when the overall cost is relatively high, it is necessary to consider tool grinding to reduce production costs and reduce resource consumption. Low-carbon green behavior.
What are the main aspects of tool grinding?
After cutting off the blunt willing edge line, grind a new edge on a relatively complete substrate; for hole processing drilling tools, it is necessary to comprehensively consider the damage of the guide part before grinding; when The cutting edge can be directly ground after normal and uniform wear; and when the edge chipping is relatively not very serious, the worn part or chipping part can be cut off by wire cutting before grinding;
Can a tool be re-coated after regrinding?
After tool grinding, the flank face (and rake face) will be ground to produce a good new edge; select the appropriate front and rear angles and edge treatment; according to customer requirements, you can choose whether to need coating according to the accuracy requirements of the tool after rework .
