1. Function and feature description

1 Overall layout of the machine tool

TV-150 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, Z axes adopt Taiwan Shangyin/Yintai roller high-precision linear guides, instead of sliding with rolling, low friction loss, sensitive response, high positioning accuracy, integrated tool magazine support, XZ axis adopts six elongated sliders The design enhances the contact surface between the main shaft and the column casting, enhances the rigidity of the machine tool and the knob torque, the cutting feed rate is fast, the machining vibration is small, and there is no creep at low speed, 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 or Germany P4 precision level screw special bearings, symmetrical axial and radial preload to ensure the afternoon noise in high-speed continuous operation.

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 event of a power failure, the brake can automatically hold the motor tightly, so that it cannot rotate, which plays a role in safety protection.

3 spindle groups

※The spindle group is produced by Taiwan professional manufacturers, with high precision and high rigidity. The bearing adopts P4 grade spindle special bearing. After the whole set of spindles is assembled under constant temperature conditions, they all pass the dynamic balance correction and running-in test, which improves the service life and reliability of the whole set of spindles.

※The spindle can realize stepless speed regulation within its speed range. The spindle is controlled by the built-in encoder of the motor, which can realize the function of spindle orientation and rigid tapping.

※The main shaft is made of nickel-chromium-molybdenum alloy steel, and after heat treatment, it has a tensile strength of up to 90Kg/mm2. The spindle is equipped with two front bearings and two rear bearings. It ensures the rotation accuracy and rigidity of the spindle under high-speed operation.

※Using German/Japanese grade P4 precision bearings, it has the characteristics of slow temperature rise, small thermal deformation, high temperature resistance, and symmetrical axial and radial preload to ensure no noise under high-speed continuous operation.

4 Cutting cooling system

Equipped with a large-flow cooling pump and a large-capacity water tank to fully ensure circulating cooling, cooling pump power: 1.0Kw, flow: 60L/min.

The end face of the headstock is equipped with cooling nozzles, which can be either water-cooled or air-cooled, and can be switched at will. The cooling process can also be controlled by M code or control panel.

Equipped with a cleaning water gun to clean the machine.

5 Pneumatic system

The pneumatic triplet can filter impurities and moisture in the source, preventing impure gas from damaging and corroding machine tool components. The solenoid valve group is controlled by the PLC program to ensure that the spindle loosening, the spindle center blowing, the spindle clamping, and the spindle air cooling can be completed quickly and accurately.

Configure the cleaning air gun to clean the machine.

6 Machine tool protection

The machine tool adopts a fully enclosed protective room, which not only prevents the coolant from splashing, but also ensures safe operation and pleasant appearance. Each guide rail of the machine tool has a stainless steel telescopic protective cover to prevent cutting and coolant from entering the machine tool, causing the guide rail and ball screw to be worn and corroded.

7 Lubrication system

The guide rail and ball screw pair all adopt the central centralized thin oil automatic lubrication system. Each node is equipped with a volumetric oil separator, which regularly and quantitatively injects oil into each lubricating part to ensure uniform lubrication of each sliding surface, effectively reducing frictional resistance and improving The movement accuracy ensures the service life of the ball screw pair and the guide rail.

8 chip removal system

The iron filings generated during the machining process fall directly onto the guard room, and the protective internal inclined surface structure makes the iron filings fall into the chip flute smoothly, and then the iron filings are sent to the chip conveyor behind the machine tool by flushing water, which greatly reduces labor amount of labor.
