Technical support method for CNC lathe
CNC
lathe method: When grinding the front cutting edge, put the chuck
fixing set into the static grinding seat, gently push the bottom
grinding wheel, put it into the bottom, rotate it to the right until it
is silent, then return to the center, take out the steering 180° , grind the other side in the same way until it is silent. When
the front cutting edge is molded, the chuck fixing device group takes
up and down the action, and the positioning pin on the grinding seat is
fixed at the center of the corner line of the set with the chuck.
CNC lathes and drill sharpening tips. CNC lathe bit sharpening method: When grinding the cutting edge, put the chuck fixing set into the static grinding seat, gently push the bottom grinding wheel, put it into the bottom, rotate it to the right until it is silent, then return to the center and take it out. Turn 180° and grind the other side in the same way until it is silent. When the front cutting edge is molded, the chuck fixing device group takes up and down the action, and the positioning pin on the grinding seat is fixed at the center of the corner line of the set with the chuck.
CNC lathes commonly used standard twist drills only sharpen two main flank faces and dressing chisel edges, large table CNC lathes, but after sharpening, the apex angle, the horizontal blade bevel angle and the length of the two main cuttings are equal, and the left and right contours are equal. After grinding the chisel edge, the cutting process is light and the chip removal is normal, which is indeed difficult. First of all, we must help students build confidence and confidence to determine motivation. After mastering the methods and techniques, it is also difficult to sharpen a qualified standard twist drill.
Secondly, it is necessary to clearly tell them that they are less likely to grind, blindly sharpen, and more and more blindly 500 tons of CNC lathes, grinding a long bit, and still do not know. Less grinding, more analysis, more understanding, theory will slowly guide practice. Less grinding, that is, no need to wear less, not grinding. This can save blind grinding and waste, and you can also study how to grind.
More to see, is to read the knowledge, diagrams in the book, to see the teacher's sharpening action, CNC lathe to see the well-qualified standard twist drill, see all kinds of sharp-cut twist drill. Looking at it with meditation, it is very important to look at it with your heart. They have a basic understanding of the "good" and "bad" twists. "Less grinding" is first of all "not grinding", and getting the drill bit in a hurry is a blind grinding.
The relative position of the CNC lathe before sharpening, the two should be balanced, and do not neglect to set the bevel for the flat edge, or ignore the flat edge in order to set the axis. These errors are often caused in practice. At this point, the drill bit is ready to contact the grinding wheel when the position is correct. The CNC lathe bit can gently touch the grinding wheel to perform a smaller amount of sharpening. When sharpening, observe the uniformity of the spark. Adjust the pressure in time and pay attention to the bit. Cooling, when re-starting the sharpening after cooling, continue to lay the position of the first and second mouth, which is often difficult to master at the beginning of the school, often involuntarily change the correctness of its position.
