HRC70 Solid carbide Endmills manufacturers tell you that every time the carbide milling cutter insert enters the cutting, the cutting edge is subjected to an impact load. The magnitude of the load depends on the cross section of the chip, the workpiece material and the type of cutting.

The feed direction of the carbide milling cutter relative to the workpiece and the rotation direction of the milling cutter are mainly divided into two milling methods:
1. Climb milling, the rotation direction of the milling cutter and the feed direction of the cutting are the same. When the cutting starts, the milling cutter bites the workpiece and cuts off the last chips.
2. Up milling, the rotation direction of the milling cutter and the cutting feed direction are opposite. The HRC70 Solid carbide Endmills manufacturer tells you that the milling cutter must slip on the workpiece for a period of time before starting to cut, starting from the cutting thickness of zero, to cutting At the end the cutting thickness reaches the maximum.
Carbide milling and down milling are not:
During down milling, the cutting force presses the workpiece toward the table, and in up milling, the cutting force makes the workpiece leave the table. HRC70 Solid carbide Endmills manufacturers tell you that because the cutting effect of down milling is the best, down milling is usually the first choice. Only when the machine tool has thread clearance problems or problems that cannot be solved by down milling, then up milling is considered.
Ideally, the diameter of the milling cutter should be larger than the width of the workpiece, and the axis of the milling cutter should always be slightly away from the centerline of the workpiece. HRC70 Solid carbide Endmills manufacturers tell you that when the tool is placed directly on the cutting center, it is easy to produce burrs. The direction of the radial cutting force will constantly change as the cutting edge enters and exits the cut, the machine spindle may vibrate and be damaged, the insert may chip and the machined surface will be very rough, the carbide milling cutter is slightly off center, the cutting force direction will be No more fluctuations, the milling cutter will receive a preload.
