Problems solved by technology

[0004] In order to solve the problem that the hardness of the cone point of the existing thimble is insufficient, and it is easy to crack or crack due to the speed and pressure, the present invention proposes a thimble device with enhanced hardness of the cone point. The present invention mainly adopts PVD coating technology A coating layer is formed on the cone tip of the thimble device. Using the coating layer with high hardness, high wear resistance and high corrosion resistance, the hardness and wear resistance of the cone tip are greatly improved, and the existing thimble is effectively solved. Various technical problems caused by insufficient hardness of the cone tip

Abstract

The invention discloses a center device with a hardness-strengthened conical cusp. The center device is provided with a center handle and a center combined with the center handle. The center is provided with the conical cusp in a conical tip shape. The PVD film coating technology is adopted for depositing a thin film shaped coating film layer on the surface of the conical cusp; by means of the coating film layer with the high hardness, high abrasion resistance and high corrosion resistance, the hardness and the abrasion resistance of the conical cusp are greatly improved, the durable service life of the conical cusp is greatly prolonged, and the requirement of a tool machine for high-rotating-speed machining can be sufficiently met.

Description

technical field [0001] The invention relates to a thimble device applied to a machine tool such as a lathe or a grinder, in particular to a thimble device with an enhanced hardness of a tapered tip. Background technique [0002] The thimble (Lathecenter, also known as the top center, the top) is installed on the tailstock of machine tools such as lathes or grinders. The method of using the thimble against the top center hole at the end of the workpiece can strengthen the clamping of the workpiece Stability, improve the stability and precision of tool machining. Among them, thimbles are roughly divided into ordinary thimbles, thimbles for small parts, half-cut thimbles for cutting end faces, rotary thimbles for high-speed cutting, and umbrella-shaped thimbles for tubes or hollow cylinders according to their functional purposes. form, such as Figure 8 Shown is an existing half-broken fixed thimble 90, the thimble 90 includes a thimble taper shank 91 for inserting and install...
