The main cutting edge of an end mill is on a cylindrical surface, and the cutting edge on the end surface is a secondary cutting edge. An end mill without a center edge cannot feed along the axial direction of the milling cutter. End mills are currently widely used In various departments such as automobile manufacturing, logistics, molds, and machinery. Next, I will give you an in-depth introduction to how to grind end mills? Basic knowledge, classification and precautions for use.
How to sharpen an end mill
1. Integral alloy woodworking end mill end edge grinding:
Use the original tool post R8 chuck to clamp the shank of the milling cutter, rotate the end mill grinding attachment by 90° horizontally, pull out the limit screw, and turn the tool post to the 360-degree rotary tool post to be able to grind the end edge position. Then according to the degree of the angle of the end cutting edge, pay attention to the feed method when grinding the relief angle of the end edge. After grinding, use the tool holder indexing device to rotate 45 degrees (4 edges) or 90 degrees (2 Edge) sharpen another tooth;
2. Integral alloy woodworking end mill side edge grinding:
Replace the original tool post table with a milling cutter sharpening accessory table, insert the R8 elastic sleeve into the tapered hole of the milling cutter accessory table, insert an end mill with a suitable diameter and size into the R8 sleeve and place it Fixed, so the end mill will no longer rotate, adjust the end mill tool to be higher than the center of the grinding wheel, and rotate the 0-40 degree tool holder worktable according to the degree of the side edge of the milling cutter to make the end mill attachment The worktable adjusts the appropriate sharpening angle, and fixes the groove needle with the guide adjustable bracket on the end mill sharpening attachment to close the spiral groove of the side edge of the end mill for guiding and guiding, and then directly rotate freely from the front to the back. Guide guide) Push the front and back twitch grinding method of the handle part to sharpen the spiral edge of the back angle of the milling cutter. After the main relief angle is ground, the auxiliary relief angle is ground, and the fixed groove needle of the guide adjustable bracket is inserted into the second inclination In the spiral groove, then grind like the first inclination.
