Problems solved by technology
There may be asymmetry in the sharpening and use of each edge of the multi-edge tool, and only a single edge will participate in the work during the work process, which will cause great wear and tear on the tool and low work efficiency and poor quality. This asymmetric angle cannot be calculated when this kind of tool is sharpened in a general machine tool, and it cannot be automatically compensated.
The cutting edge is uneven, and due to the uneven force during work, it will cause vibration during processing, which will easily lead to overheating, annealing and chipping of the cutting edge, which will affect the quality of the tool and workpiece, aggravate the wear of the tool, and affect the service life of the tool.

Embodiment Construction
[0022] The present invention will be described in further detail below in conjunction with the embodiments and with reference to the accompanying drawings.
[0023] The method of sharpening the asymmetrical multi-edged drill adopts the following steps:
[0024] (1) Put the double-edged asymmetric drill 6 to be sharpened into the drill clamp on the drill holder 8 and clamp it. After the oil cylinder 801 installed on the drill holder 8 is stretched out, the adjustment nut 802 is fine-tuned to make the detection device 7 The measuring head 701 contacts the back of the drill bit 6;
[0025] (2) The drill bit 6 rotates under the drive of the drill bit holder 8 motor. When the measuring head 701 just falls into the groove of the drill bit 6, the signal detection part 704 inputs the signal into the industrial computer 9, and the industrial computer 9 calculates the rotation axis of the drill bit 6. The current coordinate, and store the current coordinate value;
[0026] (3) Then th...

The invention discloses an asymmetric multi-cutting-edge cutter sharpening method for automatically positioning, detecting and compensating the sharpening of an asymmetric multi-cutting-edge cutter, and a numerically controlled sharpener for sharpening the asymmetric multi-cutting-edge cutter. A probe of a detecting device is used for detecting positions of the cutting edges of the asymmetric multi-cutting-edge cutter, an industrial personal computer is used for calculation to match a sharpening model which is saved in the industrial personal computer and capable of performing best compensation for the cutting edges, and the numerically controlled sharpener controlled by the industrial personal computer is used for sharpening, so the respective main cutting edges of the sharpened asymmetric multi-cutting-edge cutter are in the same height; therefore, the invention can sharpen the multi-cutting-edge cutter of which the main cutting edges are in the same height, and has the advantages of prolonging the service life of the cutter and improving the quality of processed workpieces.
Description
technical field [0001] The present invention relates to a sharpening method for asymmetrical multi-edged knives, in particular to a method for sharpening asymmetrical multi-edged knives with automatic positioning, automatic detection and automatic compensation. CNC grinding machine for cutting tools. Background technique [0002] The quality of tool sharpening directly affects the quality and efficiency of processing. There may be asymmetry in the sharpening and use of each edge of the multi-edge tool, and only a single edge will participate in the work during the work process, which will cause great wear and tear on the tool and low work efficiency and poor quality. When this kind of tool is sharpened in a general machine tool, the asymmetric angle cannot be calculated, let alone automatically compensated. The cutting edge is uneven, and due to the uneven force during work, it will cause vibration during processing, which will easily lead to overheating, annealing and chi...
