Description

Technical Field

[0001] The utility model relates to the technical field of milling cutter processing, in particular to an auxiliary heating device. Background Art

[0002] A milling cutter is a rotating tool with one or more teeth used for milling. When working, each tooth cuts off the excess of the workpiece intermittently in sequence. When optimizing the milling effect, the blade of the milling cutter is another important factor. If more than one blade participates in cutting at any time, it is an advantage, but too many blades participate in cutting at the same time is a disadvantage. During cutting, each cutting edge cannot cut at the same time. The required power is related to the number of cutting edges participating in cutting. In terms of the chip formation process, cutting edge load and processing results, the position of the milling cutter relative to the workpiece plays an important role. Milling cutters are mainly used to process planes, steps, grooves, forming surfaces and cut off workpieces on milling machines. Diamond coating is a thin film grown on the surface at a suitable temperature. The hot wire heating method has a certain temperature gradient. Therefore, when the coating position is long, it is necessary to control the temperature of the required coating position by lifting the workbench. In the prior art, for a milling cutter with a longer coating position, the coating will be uneven due to the uneven temperature between the upper and lower parts, resulting in a taper phenomenon, and the time required for coating will also be increased. Therefore, an auxiliary heating device is proposed to solve the above-mentioned problem. Utility Model Content
