one. Function and feature description
1 Overall layout of machine tools
The VMC 855 vertical machining center adopts a vertical frame layout. The column is fixed on the bed. The spindle box moves up and down along the column (Z direction), the slide moves longitudinally along the bed ( Y direction) , and the workbench moves laterally along the slide (Z direction) . X-direction) structure.
Large parts such as the bed, worktable, slide, column, spindle box, etc. are all made of high-strength cast iron materials, and are shaped using resin sand technology, and are treated twice with aging treatment to eliminate stress. These large parts are designed using SW and Ansys optimization to improve the stiffness and stability of the large parts and the entire machine, effectively suppressing the deformation and vibration of the machine tool caused by cutting forces.
2Drag system
The X, Y, and Z axes adopt roller linear guides (for gantry machining centers), which have small dynamic and static friction, high sensitivity, small vibration at high speeds, no creeping at low speeds, high positioning accuracy, and excellent servo drive performance, which improves the accuracy and precision of machine tools. stability.
X, Y, Z axis servo motors are directly connected to high-precision ball screws through elastic couplings, reducing intermediate links and achieving gapless transmission, with flexible feeding, accurate positioning, and high transmission precision.
The Z-axis servo motor has an automatic brake function. In the event of a power outage, the brake can automatically hold the motor shaft tightly so that it cannot rotate, which plays a role in safety protection.
3 spindle group
The spindle group is produced by professional manufacturers in Taiwan and has high precision and high rigidity. The bearings adopt P4 grade special bearings for spindles . After the entire set of spindles is assembled under constant temperature conditions, they pass dynamic balance correction and running-in tests, which improves the service life and reliability of the entire set of spindles .
The spindle can achieve stepless speed regulation within its speed range. The spindle is controlled by a built-in encoder in the motor, which can realize spindle orientation and rigid tapping functions.
4 tool magazine
A disc-type tool magazine is used, which is installed on the side of the column. When changing tools, the cutter head is pushed left and right by the cylinder. The cylinder is equipped with a proximity switch to ensure the accurate tool changing position. After the cutter head reaches the tool changing position, the spindle moves up and down to realize tool return and grabbing. Knife, the tool changing process is simple and reliable.
5 cutting cooling system
Equipped with a large-flow cooling pump and a large-capacity water tank to fully ensure circulating cooling. Cooling pump power: 0.4Kw, pressure: 1.2bar.
The end face of the spindle box is equipped with a cooling nozzle, which can be water-cooled or air-cooled, and can be switched at will. The cooling process can be controlled through M code or control panel.
Equipped with a cleaning air gun for cleaning machine tools.
6Pneumatic system
The pneumatic triplex can filter impurities and moisture in the air source to prevent impure gas from damaging and corroding machine tool components. The solenoid valve group is controlled by the PLC program to ensure that spindle tool unclamping, spindle center air blowing, spindle tool clamping, spindle air cooling and other actions can be completed quickly and accurately.
7Machine tool protection
The machine tool adopts a protective room that meets safety standards, which not only prevents coolant from splashing, but also ensures safe operation and a pleasant appearance. Each guide rail of the machine tool has a protective cover to prevent chips and coolant from entering the machine tool and protect the guide rails and ball screws from wear and corrosion.
8 Lubrication system
The guide rails and ball screw pairs are all lubricated by centralized automatic thin oil. Each node is equipped with a quantitative oil separator, which regularly and quantitatively injects oil into each lubricating part to ensure that each sliding surface is evenly lubricated, effectively reducing friction resistance and improving movement. The accuracy ensures the service life of the ball screw pair and guide rail.
