The vertical machining center is mainly used to process parts with high precision, many processes and complex shapes such as plates, discs, shells, molds, etc. It can continuously complete milling, drilling, expanding, boring and tapping in one clamping. And two-dimensional three-dimensional curved surface, accurate processing of inclined plane, the processing can be programmed, and the production cycle is shortened, so that users can obtain good economic benefits.

1. Function and feature description

1 Overall layout of the machine tool

TV-106 vertical machining center adopts a vertical frame layout, the column is fixed on the machine body, the headstock moves up and down along the column (Z direction) / the carriage moves longitudinally along the bed (Y direction) / the worktable moves laterally along the carriage (X-direction) structure.

The bed, worktable, sliding seat, column, spindle box and other large parts are made of high-strength cast iron material, and the shape is resin sand process, and the stress is relieved by two aging treatments. These large parts are optimized by Pro/E and Ansys to improve the rigidity and stability of the large parts and the whole machine, and effectively suppress the deformation and vibration of the machine tool caused by cutting force.

The machine body adopts Meehan sodium cast iron structure and rigid box structure design, with high rigidity and high stability.

2 Drag system

X, Y, and Z axes adopt Taiwan's high-precision, heavy-duty linear guides, which use rolling instead of sliding, with low friction loss, sensitive response, and high positioning accuracy. X/Z axes are designed with roller/ball extended six-slider , Enhance the contact surface between the main shaft and the column casting, enhance the rigidity of the machine tool and the knob torque, the cutting feed rate is fast, the machining vibration is small, the low speed has no crawling, and the precision and stability of the machine tool are improved. Higher surface quality of the workpiece can be obtained, and higher machining accuracy can be obtained due to good heat dissipation conditions and less thermal deformation of the workpiece.

Using Japan's P4 precision grade screw special bearings, symmetrical axial and radial preload ensure high-speed continuous operation afternoon noise.

The three-axis adopts Taiwan C3-grade precision ball screw with preload at the end, which ensures excellent transmission accuracy and positioning accuracy.

X, Y, Z three-axis servo motors are directly connected with high-precision ball screws through elastic coupling joints, reducing intermediate links, realizing gap-free transmission, flexible feeding, accurate positioning, and high transmission precision.

The Z-axis servo motor has an automatic brake function. In the case of a power failure, the brake can automatically hold the motor tightly, but it cannot rotate, which plays a role in safety protection...
