Problems solved by technology
[0003] This type of collet is generally used in the processing of precision instrument and instrument parts. The diameter of the processed parts is 0.5mm-2.5mm, the diameter deviation of the processed parts is ±0.003mm, the surface roughness of the inner hole of the collet is Ra0.1, and the working surface is rough. Degree Ra0.2; At present, the existing problem is that there is direct contact between the workpiece and the chuck, and there will be friction between the two, which is easy to wear, which will eventually cause poor concentricity between the workpiece and the chuck shaft hole, and the accuracy of the processed workpiece Lowering and chuck wear causing scrap

Embodiment Construction
[0026] Chuck processing method of the present invention, comprises the following steps:
[0027] The first step is blanking to obtain the workpiece blank;
[0028] The second step is to heat-treat the blank and anneal to obtain a rough blank with a hardness not greater than 197HB;
[0029] The third step is to turn the annealed blank, remove most of the machining allowance, and obtain the chuck of the required size;
[0030] The fourth step is to inspect the size and roughness of each part of the chuck after turning, and enter the next process if it meets the requirements;
[0031] The fifth step is to weld the cemented carbide sleeve to the front end of the inner hole of the chuck blank by brazing;
[0032] The sixth step is to heat-treat and anneal the chuck blank welded with the cemented carbide sleeve, and the hardness of the annealed blank is controlled at 197HB to 200HB;
[0033] The seventh step is to check whether the chuck after heat treatment is cracked, desoldere...

Abstract
The invention relates to the field of machining, in particular to a chuck machining method. The method comprises the following steps: feeding materials; performing heat treatment of blanks; turning annealed blanks; checking the sizes and roughness of all parts of turned chucks; brazing hard alloy sleeves; performing heat treatment of the chucks welded with the hard alloy sleeves; detecting whether the phenomena of cracking, unsoldering and obvious amesiality exist in the chucks subjected to heat treatment; ,milling grooves in the head parts of qualified chuck blanks welded with the hard alloy sleeves in a radial direction; checking whether the sizes of the milled chucks meet the requirement; performing heat treatment of the chuck again; grinding inner holes of the chucks; and further grinding the peripheral surfaces of the chucks. The method is simple in machining process, facilitates manufacturing, can ensure the machining quality and dimensional precision of workpieces, prolongs the service lives of products and improves the production efficiency.
Description
technical field [0001] The invention relates to the field of mechanical processing, in particular to a chuck processing method. Background technique [0002] Under the action of cutting force, the slender precision instrument workpiece is prone to large bending deformation, which will affect the machining accuracy. In order to reduce the force deformation of such slender workpieces during the cutting process, a fixed chuck is installed in the middle of the bed of the machine tool or in front of the headstock. The chuck plays the role of supporting the slender workpiece and can be used to directly The cutting force during processing is due to the rotation of the workpiece during processing, so there should be a certain gap between the workpiece and the inner hole of the chuck; when the gap between the chuck and the workpiece is too large, it will affect the accuracy of the workpiece. When the gap between the chuck and the workpiece is too small, the surface finish and precis...
