1、General layout of the machine tools

The CMC500F five-sided machining center adopts a five-sided frame layout, an integrated design of the column and the bed. The ram moves up and down along the sliding seat (Z direction), the sliding seat moves longitudinally along the sliding plate (Y direction), and the sliding plate moves horizontally along the column (X It is a structure in which the turntable tilts and rotates along the Y axis (B axis), and the turntable surface moves 360° along the Z axis (C axis). The bed, column, sliding seat, sliding plate, sliding plate and other large parts are all made of high-strength Meehanite castings. These large parts are optimized and designed with 3D computer software. The ribs are arranged reasonably and have a complete heat treatment process to eliminate residual stress. Ensure that the whole machine has sufficient strength, rigidity and high stability.

2、SYSTEM

The CNC system is equipped with FANUC 0I MF (1 type) system and supporting drivers, with complete functions and easy operation; standard communication interface, UF socket and related software, with DNC online processing function.

3、Drag system

X, Y, and Z axis guide pairs adopt 35mm ultra-wide roller linear guides from Taiwan Shangyin, with low dynamic and static friction, low abrasion, high positioning accuracy, high sensitivity, low high-speed vibration, long service life, interchangeability, and servo drive performance Excellent, improve the accuracy and precision stability of the machine tool. The X, Y, and Z axis servo motors are directly connected to the Taiwan Shangyin high-precision ball screw through flexible couplings, reducing intermediate links, realizing backlash-free transmission, flexible feeding, accurate positioning, and high transmission accuracy. The Z-axis servo motor has an automatic brake function. In the event of a power failure, the automatic brake can hold the motor shaft tightly to prevent it from rotating, which plays a role of safety protection.

The B and C axis servo motors are driven by high-precision timing belts, which reduces the transmission error, realizes high-precision transmission, accurate positioning and high transmission accuracy.

4、Spindle

The spindle group adopts Taiwan’s 12000rpm direct-connected spindle, which has high precision and high rigidity. The bearing adopts the special NSK bearing for the P4 spindle. After the whole spindle is assembled under the constant temperature condition, it has passed the dynamic balance correction and running-in test, which improves the service life and reliability of the whole spindle. It is equipped with a high-precision oil cooler to cool the electric spindle unit, and it can realize stepless speed regulation within its speed range. The spindle is controlled by the built-in encoder of the motor, which can realize spindle orientation and rigid tapping functions.

5、Turntable group

The turntable group adopts high-precision needle roller bearings. After the complete set of turntables are also assembled under constant temperature conditions, they have passed the dynamic balance correction and running-in test, which improves the service life and reliability of the complete set of turntables. The B-axis is driven by a ball screw and the rotation range is from -5° to +110°; the C-axis is driven by a worm gear and the rotation range is 360°. The diameter of the turntable surface is φ630X500, and the maximum load-bearing capacity is 200Kg, which can complete the five-sided processing of larger and complex parts.

6、Tool magazine

It adopts Taiwan disc type 24 tool magazine, which is installed on the side of the column. The cutter head is driven and positioned by the roller cam mechanism during tool change. After the spindle reaches the tool change position, the robot tool changer (ATC) completes the tool return and feed. , ATC is a gear hobbing cam mechanism, which can run at high speed without noise after preloading, making the tool change process fast and accurate.

7、Cutting and cooling system

Equipped with a large-flow cooling pump and a large-capacity water tank to fully ensure circulating cooling. Cooling pump power: 828W, 66.7L/min large-flow cooling pump, high enough to provide cooling. The end face of the spindle box is equipped with cooling nozzles, which can be water-cooled or air-cooled, and can be switched at will. Equipped with a cleaning air gun to clean the machine tool.

8、pneumatic system

The pneumatic two-piece can filter impurities and moisture in the air source, and prevent impure gas from damaging and corroding machine tool parts. The solenoid valve group is controlled by the PLC program to ensure that the spindle tool release, spindle center blowing, spindle tool clamping and other actions can be completed quickly and accurately.

9、Machine tool protection

The machine tool adopts a protective room that meets safety standards, 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 protective cover to prevent chips and coolant from entering the inside of the machine tool, and to protect the guide rail and ball screw from wear and corrosion.

10、Lubrication system

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

11、Chip removal system

The iron filings produced during the processing process directly fall onto the protective room. The internal slope structure of the protection makes the iron filings smoothly slide down into the chain plate type chip conveyor, and then are transported to the chip collecting trolley through the chain plate.
