Method for leading titanium alloy grinding wheel base body to keep dynamic balance in high-speed rotation

Abstract

The invention relates to a method for leading a titanium alloy grinding wheel base body to keep dynamic balance in high-speed rotation. The grinding wheel base body is made of titanium alloy, a circle of grooves A are arranged on the cylindrical surface which is close to the circumference and at one end of the base body shaped as a plane, the base body is divided into two parts of a wheel hub and a wheel rim, the end face of the wheel rim is lower than that of the wheel hub, the bottom surface of a concave station is provided with a groove B to lead the lower surface of the wheel rub to be higher than the bottom surface of the groove B, the cylindrical surface of the wheel hub is evenly provided with at least two through holes around an axial hole, the center of each through hole is positioned on one circumference; the base body meets the following form and position tolerance requirement: the parallelism of the upper surface of the wheel hub and the upper surface of the wheel rim is 0.02mm, the parallelism of the lower surface of the wheel hub and the lower surface of the wheel rim is 0.02, the perpendicularity of the axial hole relative to the upper surface of the wheel hub is 0.003mm, the planeness of the supper surface of the wheel hub is 0.005mm, and the perpendicularity of the lower surface of the wheel hub to the axial hole is 0.005mm. The grinding wheel base body has good static and dynamic equilibrium and small vibration.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to a method for maintaining a dynamic balance of a titanium alloy grinding wheel base during high-speed rotation. Background technique [0002] The superhard material grinding wheel is a kind of grinding tool with a large amount of use and a wide range of applications. When used, it rotates at a high speed and can be used for rough grinding and semi-finishing of the outer circle, inner circle, plane and various shapes of metal or non-metal workpieces. Grinding and fine grinding as well as grooving and cutting off, etc. The superhard material grinding wheel is a circular bonded abrasive tool with a through hole in the center made of diamond, cubic boron nitride abrasives and binder resin, etc. after vacuum, spraying and sintering. The superhard material grinding wheel needs to be matched and installed with the corresponding chuck before use. The chuck is...
