HRC70 Solid carbide Endmills manufacturers tell you that the feed direction of the carbide milling cutter relative to the workpiece and the rotation direction of the milling cutter mainly include the following two milling methods:

The first is down 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 chip.
The second is up-cut milling. The rotation direction of the milling cutter is opposite to the feeding direction of the cutting. The milling cutter must slip on the workpiece for a period before starting to cut, starting with the cutting thickness of zero, and reaching the cutting thickness at the end of the cutting. maximum.
During climb milling, the cutting force presses the workpiece toward the table, while 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.
Every time the carbide milling insert enters the cut, the cutting edge is subjected to an impact load, which depends on the cross section of the chip, the workpiece material and the type of cutting. HRC70 Solid carbide Endmills manufacturers tell you that under ideal conditions, 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. When the tool is placed directly on the cutting center, it is very easy to produce burrs. HRC70 Solid carbide Endmills manufacturers tell you that the direction of the radial cutting force will constantly change as the cutting edge enters and exits the cut, the machine tool spindle may vibrate and be damaged, the insert may chip and the machined surface will be very rough, the carbide end mill slightly Off-center, the direction of the cutting force will no longer fluctuate and the milling cutter will receive a preload.
