Alloyed steel work-piece tapping oil and production method

Abstract

The invention discloses a tapping oil for alloy steel workpiece that reduces cutting temperature and force for tapping to maximum limit, improves process efficiency of tapping and cutting, ensures precision and surface quality of the workpiece and prolongs life of cutting tool for tapping, reduces cost, satisfies requirements of environmental protection, and method for making the same. Weight percentage of the raw material is 5# high speed oil 38%-42%, 20# machine oil 18%-22%, vulcanized oleic acid 9-13%, paraffinum chloride 18-22%, sulfur phosphorus butanol-octanol zinc salt (T-202) 1-3%, 2,6-Di-tert-butyl-4-methylphenol 0.5-1.5%, lead naphthenate 4-6%, sodium petroleum sulfonate 0.5-1.5%, 2-methyl-3(2H)-Isothiazolone 0.1-0.2%. The production process is synthesis with stirring under condition of normal temperature - high temperature - normal temperature.

Description

Technical field: [0001] The invention relates to a tapping fluid for metal tapping, in particular to a tapping fluid that can minimize the tapping cutting temperature and cutting force, improve the tapping cutting efficiency, ensure the accuracy and surface quality of the workpiece, and can extend the tapping Alloy steel workpiece tapping oil and production method that can reduce the service life of cutting tools, reduce costs, and meet environmental protection requirements. Background technique: [0002] Metal tapping is the use of special tools to cut the metal blank under the condition of the power provided by the machine tool to obtain the internal and external threaded workpieces that meet the requirements of the shape, size, accuracy and surface quality. It is the most common in metal cutting processing. A process with a wide range of applications. During the tapping process, the tapping cutting layer is squeezed by the rake face of the tool to produce plastic deformation d...

AI Technical Summary

Problems solved by technology

Due to the lack of lubricity and insufficient cooling of the tapping oil used for the manufacture of alloy steel (42CrMn, 20CrMnSi, 25CrMnSi, 30CrMnSi, 30CrMnSiA, 40CrMnMo, 30CrMnTi, etc.) for large nuts, the following phenomena will occur during the production process :

[0003] 1. Collapse and tooth loss at the screw crest and thread part;

[0004] 2. The thread surface is rough and the finish is low;

[0005] 3. The cutting edge of the tapping tool is easy to hit the knife, and the service life is short
