A CNC Vertical Precision Milling Machine

Abstract

The invention relates to the technical field of mechanical processing equipment, and discloses a numerically controlled vertical precision milling machine, which includes a transmission base, a shaft sleeve is fixedly sleeved in the middle of the transmission base, and a special-shaped groove is opened in the middle of the shaft sleeve, and the special-shaped The slot is clamped with a fastening block, and the bottom end of the shaft sleeve is threadedly connected with a limit nut and the position of the fastening block is clamped by tightening the limit nut. The CNC vertical precision milling machine rotates the rotating shaft to drive the adjustment of the front and back sides of the electromagnetic strip, which can generate suction and repulsion with the permanent magnet. The repulsive force generated between them, and the repulsive force between the two can be controlled by adjusting the current of the electromagnetic strip electric control system, and an additional up and down impact force is provided while rotating and cutting. Compared with traditional milling, which uses layers from top to bottom Go to the way of milling the workpiece (refer to Figure 6) to increase the cutting rate.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a numerically controlled vertical precision milling machine. Background technique [0002] CNC milling machine is a machine tool that integrates a digital control system on an ordinary milling machine and can perform milling processing more accurately under the control of program codes. There are various forms of CNC milling machines. There are many similarities. The machine tool is composed of six main parts, namely the bed part, the milling mechanism part, the table part, the infeed part, the lifting table part, the cooling and lubrication part, from the requirements of the development of manufacturing technology, with the With the emergence of new materials and new processes, as well as market competition's requirements for low cost, metal cutting is developing towards higher and higher cutting speed and precision, which requires the cutting speed of CN...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, whether the top or the side of the workpiece is processed, layer-by-layer milling is adopted. The same groove needs to be milled several times or even more than ten times to achieve the desired effect, which affects the processing efficiency. At the same time, from top to bottom When milling, it is easy to form material extrusion and cause the problem of milling cutter breakage
