I. functions and features description

1 overall layout of machine tool

Vertical machining centers vertical frame layout, bed, table, slides, columns, spindle box, large parts are made of high strength resin alloy inoculation HT300 Meehanite, two aged to eliminate stress. The large pro/e and Ansys is used to optimize the design, improve cargo and machine stiffness and stability, suppress the machine deformation of the cutting force and vibration.

2 machine tool Guide

Machining center guide with multiple aging and depth of not less than 3mm Super Audio hardening process, imports by rail grinder for precision grinding. Rail contact surface with artificial high precision lapping and shovels spent and attached to imported PTFE-b, good shock absorption, remain permanently stable precision.

3 motor systems

X, y, and z-axis guide of linear rolling Guide, dynamic and static friction small, high sensitivity, high speed vibration, without crawling at low speed, high precision, servo-driven performance, improve the accuracy and stability of machine tools.

X, y, z axis servo motors through elastic coupling with high-precision ball screw directly, reduce intermediate links, free space transmission, flexible, accurate, high drive precision.

Z axis servo motor with auto brake function, in the case of power outages that can automatically brake to hold the motor shaft so that it can't move, play a role in security. Spindle box adopts the nitrogen balance, lift running smooth, reverse-sensitive response, no impact, reduce servo response lag, can greatly improve the precision of the workpiece surface and surface roughness

4 spindle unit

Spindle unit using Taiwan brand products, with high precision and high rigidity. Bearings with P4 spindle bearings, spindle packages in the condition of constant temperature after Assembly is complete, by balancing and running tests, improving the reliability of the entire service life of the spindle and.

Spindle speed range can realize stepless speed spindle with built-in encoder motor control, spindle orientation and rigid tapping capability can be achieved.

5-tool library

Disc cutter, mounted on the column side tool changer cutter driven by roller cam and when positioning spindle reach tool change position, by machine tool changer (ATC) also send knives and knife, ATC for roller gear cam, after preloading high-speed noise-free operation, makes the tool changing process fast and accurate.

6 cooling system

Equipped with a high-flow cooling pumps and bulk tank, fully guaranteed circulation cooling, headstock face equipped with cooling nozzles can be either water-cooled or air-cooled, and freely switch cooling process can be controlled through the m-code or control panel. Configure clean air guns, used to clean the machine.

7 pneumatic systems

Pneumatic FRL to filter impurities and moisture in the air to prevent pure gases for damage and corrosion of machine parts. Electromagnetic valves by PLC program control, ensure the spindle knife, spindle air, shaft tool holder, spindle air cooling and other actions can be completed quickly and accurately.

8 machine tool protection

Machine safety standards of protection, both to prevent coolant splash, and to ensure safe operation and pleasant appearance. Press the guide have a protective cover to prevent chips, cooling liquid into the machine tool, guides and ball screw from wear and corrosion.

9 lubrication system

Guides, ball screws automatic centralized oil lubrication is used, each node features quantity oil separators, and timing to the lubrication oil to ensure uniform lubrication sliding surface, effectively reducing the frictional resistance, improves the precision of movement and guarantee the service life of the ball screw and guide.

10-chip system

Iron produced in the process falls directly on the protection, protective inner bevel design allows very smooth sliding with iron filings to flutes, then screw chip conveyor to transport iron into the scrap car, simple, practical and economical.
