Information

HRC70 carbide end mill manufacturers tell you that carbide end mills refer to milling cutters made of cemented carbide. To understand cemented carbide milling cutters, you must first know what cemented carbide is. Cemented carbide is mainly composed of carbide (WC, TiC) micron powder of high-hardness refractory metal, with cobalt (Co) or nickel (Ni) as the main component. , Molybdenum (Mo) as a binder, powder metallurgy products sintered in a vacuum furnace or hydrogen reduction furnace.

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. The HRC70 carbide end mill manufacturer tells you that the milling cutter will bite the workpiece and cut off the last chips when it starts cutting.
The second is up milling, the rotation direction of the milling cutter and the cutting feed direction are opposite, the HRC70 carbide end mill manufacturer tells you that the milling cutter must slip on the workpiece for a period of time before starting to cut, starting with the cutting thickness of zero, The cutting thickness reaches the maximum at the end of cutting.
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. The manufacturer of HRC70 carbide end mill tells you that because the cutting effect of down milling is the best, down milling is usually the first choice. Only when there is a thread clearance problem on the machine tool or there is a problem that cannot be solved by down milling, up milling is considered.
The HRC70 carbide end mill manufacturer tells you that every time the carbide end mill 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. 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. When the tool is placed directly on the cutting center, it is very easy to produce burrs. The HRC70 carbide end mill manufacturer tells you that the direction of the radial cutting force will change continuously when 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 milling cutter slightly Off-center, the direction of the cutting force will no longer fluctuate and the milling cutter will receive a preload.
