To be engaged in the person at machining industry for, repair grinding cutting tool is a technical ability that must want to master. No matter lathe jockey, milling machine jockey or bore benchwork, passivation can appear inevitably after cutting tool uses period of time, numerical control machining center also is such. To do not affect production, or changes new cutting tool, or must undertake grinding a knife. Produce cost to reduce for the enterprise, general meeting asks operator adroitness grinds a knife, talk about the method grinding a knife of numerical control milling cutter next!
The first pace, also be the most crucial make level area
When make level face, can do with a standard piece fiducial, cutting tool is ground in the blade on emery wheel hind, it is cutting tool on standard piece than be opposite the following, must planar make level, this is cutting tool whether the key that has ground, if pursue one:
When opening crossed slot, the edge of both sides leaves to go up in a line, groove leaves appreciably is a bit more greatly, better blade is ground from the back, if pursue 2:
When blade grinds point, the angle with arbor maintains emery wheel to arrive in 5 ° between 10 ° , if pursue 3:
When the horn after blade is ground, want to note the size of the horn after control, horn grinds blade of too much and easy collapse after, if pursue 4:
Grinding milling cutter basically is armrest feeling, practice more, skill comes from practice. If finished product pursues 5:
