Problems solved by technology

[0006] The purpose of this invention is to make up for the above shortcomings. We use the method of combining electroplated diamond taps and ultrasonic rotary processing to process hard and brittle materials, and effectively solve the problem of ultrasonic forming processing due to serious tool loss and uneven suspended abrasives in the processing gap. According to the characteristics of ultrasonic vibration, referring to the structure and working principle of the current machine tool, design the spindle of the ultrasonic rotary machining machine tool to complete the drilling and tapping of ceramic materials

Abstract

The invention relates to a design of a main shaft of a rotary ultrasonic machine, in particular to an efficient device formed by combining an ultrasonic machine tool and a general machine tool. The efficient device can finish the drilling and tapping of ceramic materials. According to the characteristics of ultrasonic vibration, the main shaft of the rotary ultrasonic machine is designed referring to the structure and working principle of the existing machine tool, and the working principle and rotary ultrasonic drilling material removing principle of the rotary ultrasonic machine are analyzed to enable the rotary ultrasonic machine to finish the drilling and tapping of ceramic materials. Ultrasonic waves are applied to a wire saw, and materials are removed by the instantaneous impact of abrasive materials, so that the surface quality of the workpiece cut by the wire saw is superior to that of the workpiece cut by a common wire saw.

Description

technical field [0001] The invention relates to a main shaft of an ultrasonic machine tool in mechanical processing equipment, in particular to a high-efficiency equipment that combines ultrasonic and ordinary machine tool processing, and can complete drilling and tapping of ceramic materials. Background technique [0002] Tapping is an internal thread processing method widely used in cutting machining, especially for small-diameter internal threads, tapping is almost the only feasible processing method. Although the ordinary tapping method can meet the production requirements in most cases, because the tapping process itself is a semi-closed multi-blade cutting process, compared with other processing methods such as turning, the cutting conditions are harsh, and the processing of small and medium-diameter internal threads And when tapping on difficult-to-machine materials, there are common problems such as large tapping torque, low thread processing accuracy, fast wear and ...
