Woodworking cutting tool machining method

Abstract

The invention discloses a woodworking cutting tool machining method and belongs to the cutting tool machining filed. The woodworking cutting tool machining method comprises the following steps of (1) bar sawing; (2) lathing; (3) milling; (3) drilling; (5) tapping; (6) burr sweeping; (7) ultrasonic cleaning; (8) blade welding; (9) sand blasting; (10) handle grinding through centreless grinding; (11) finish lathing bearing position; (12) ultrasonic cleaning; (13) cutting edge grinding; (14) ultrasonic cleaning; (15) bearing placing. The woodworking cutting tool machining method which aims at providing a cutting tool which is stable in quality, safe in utilization is applied to non-metallic machining.

Description

technical field [0001] The invention relates to a processing method of a cutting tool, and more specifically, relates to a processing method of a woodworking cutting tool. Background technique [0002] Traditional woodworking knives are usually installed in industrial gong beds, computer engraving machines, portable gong machines and other equipment. The power of the equipment is usually 1.0KW-5.5KW, and the speed range is between 6000 rpm and 20000 rpm. To process logs, man-made panels, plexiglass and other furniture and home decoration wire and other non-metallic materials. In the processing of traditional woodworking tools, there is no strict control over the processing methods of each step and process, and there are many problems in some important steps and processes. Specifically: [0003] First, when traditional woodworking knives process the knife body, in order to reduce the amount of machining residue, two processing methods, precision casting or precision forging...

AI Technical Summary

Problems solved by technology

[0004] (1) During precision forging or precision casting, shrinkage cavities, uneven structure, dark cracks, poor dynamic balance and many other defects often occur at the joint between the clamping handle and the diameter. If some qualified manufacturers will Do a dynamic balance test, and the tool with a dynamic balance defect is often found to use fillers to make up for the balance defect of the cutter body, but this method of filler will affect the chip removal effect of the tool, and the appearance quality will also be damaged

(2) When the tool is running at a high speed, it is easy to cause the tool body to fly off and cause work-related accidents, which poses a great safety hazard

[0005] Second, when the blade is welded, it is easy to affect the quality of the tool due to the lack of strict process control in the following processes:

[0006] (1) After the blade is cleaned, the water is not dried within a certain period of time, so that the combination of water, oxygen and cobalt in the alloy will affect the internal quality of the blade

(2) Repeated heating of the welding surface will cause the blade to crack

(3) After the blade is welded, if the cooling temperature of the cutter body is uneven, the blade will affect the welding quality due to the difference in shrinkage coefficient between the matrix and the blade material

[0007] Third, when grinding the cutting edge, it is easy to affect the quality of the tool due to the lack of strict process control in the following processes:

[0008] (1) The accuracy of the grinding chuck and the selection of the grinding wheel are not suitable, resulting in the grinding accuracy not meeting the product requirements

(2) Because some tools have a shear angle and are a gyroscopic body, ordinary tool grinders cannot achieve the equal relief angle of the tool body, so that the cutting force and chip removal of the tool edge are uneven, and the service life of the tool is shortened

(3) The processing speed control of each process is inaccurate when sharpening the edge, resulting in cracks and burns on the blade surface, resulting in a low pass rate of the blade
