Before grinding milling cutter, the grinding wheel needs to be inspected. If the grinding wheel is beating, the cylinder is irregular, the round Angle is too large, etc., Then we have to fix it. The grinding wheel corrector (diamond dresser, tooth plate dresser, etc.) can be used to trim the cylinder of grinding wheel, and the grinding wheel can be used to repair the grinding wheel. If the side plane of the grinding wheel is not flat, you can change the grinding wheel. 

 

Grinding technology of end face milling cutter:

1. No matter how many edges of the end milling cutter, first of all, the blade face is perpendicular to the axis, which is the key to ensure that the highest point of the blade can be in the same plane.

2. The technology of vertical milling cutter with cross cutting slot.

If the front of four vertical milling cutter blade end face no circular groove, it need to use wheel rounded corners along the direction of the spiral groove of the milling cutter to restart the cross slot, depth of about 1 ~ 2 mm (too deep cleft, light is not easy to grind out after vice Angle). When opening the groove, pay attention to the side of the grinding wheel not to touch the other edge of the blade. (note: this cross groove has the effect of cutting, if not open, then the Angle of the center is increased).

3. Grinding Technology of End Face Cutting Edge of End Milling Cutter

① When we respectively grinding each blade, we should be based on each blade tip, to keep the tip. We should grind anterior horn (no collapse edge can not grind), Angle, deputy after (if it is a large amount of cutting which need better strength, we suggested that grinding the part which is in front of the knife to increasing wedge blade) and blade Angle.

② the angle of choice is the rear angle of 6 ° ~ 8 °, (vice angle 30 ° ~ 45 °) blade angle of 1 ° ~ 3 °. The choice of the rear Angle is to change according to the hardness of the workpiece, the hardness is high, the angle can be smaller; The Angle selection principle of blade Angle is that the four blades must be recessed in the middle, and The flatter Angle, the better accuracy of the roughness. In this case, the depth of processing depth, for example, more than 2mm (but should be in the license range), the roughness accuracy will be better, because the whole cutting blade is involved in the cutting results.

 

③When the blade is finished, stand up this milling cutter. If the axis is vertical, All the edges of the blade can be flattened, The Angle of the blade can be evenly distributed, so that it can meet the requirements.

 

4. Sharpening technology of milling cutter’s main edge. If the main edge of themilling cutter is worn, We will grind the grinding wheel along the spiral line. It is different for beginner. However, after grinding, the taper is usually followed, and the smaller the taper shows the higher the level of operation.
