Embodiment Construction

[0013] A production process of a rotary top material, which specifically includes the following process:

[0014] Fix the shaft diameter part of the cemented carbide tip, and process it according to the structure size of the movable tip. When machining the shaft diameter assembled with the bearing, it must be ensured that the tip is concentric with the shaft diameter. After the cemented carbide tip is installed, put it into the tailstock of the machine tool, check the tip runout with a magnetic force meter, and use it only after it is qualified.

Abstract

A production process of a live centre material is characterized by comprising the following technological processes that a shaft diameter part of a hard alloy fixed centre is machined according to the structure and dimension of a live centre, and when the shaft diameter assembled with a bearing is machined, concentricity between the centre and the shaft diameter must be guaranteed. After the hard alloy fixed centre is installed, the hard alloy centre is placed into a tailstock of a machine tool, jittering of the centre is checked by means of a magnetic meter, and the centre can be used after the centre is qualified. The hard alloy material is high in rigidity and resistant to abrasion, abrasion to the live centre hardly exists in use, quality of component machining is good and stable, and meanwhile production cost and expenses can be greatly reduced.

Description

technical field [0001] The invention relates to a production process of a rotary top material. Background technique [0002] The material of the rotary top is generally made of alloy tool steel, the disadvantage is that [0003] 1. The surface hardness of the top is low, and it is easy to wear after frequent use. [0004] 2. Affect the quality of machined parts. [0005] 3. Spare parts and repair costs are high. SUMMARY OF THE INVENTION [0006] The purpose of the present invention is to overcome the above-mentioned deficiencies of existing materials, and provide a hard alloy material tip. [0007] Adopt technical solutions [0008] A production process of a rotary top material is characterized in that it includes the following process: the shaft diameter part of the fixed center of the cemented carbide is processed according to the structure and size of the movable center, and when processing the shaft diameter of the bearing assembly, it is necessary to ensure that t...
