CTB Serie – CNC 5 Axis

Five-Axis Machining Center

The V5-630B five-axis machining center adopts a stable C-shaped structure, the column is fixed on the bed, the slide plate moves laterally along the column (X direction), the slide seat moves longitudinally (Y direction), and the headstock moves vertically along the slide seat ( Z direction). The worktable adopts the self-developed direct-drive single-arm cradle structure, and various performance indicators have reached the international advanced level.

CNC Controller: Siemens 840D

Feeding system

The X, Y, Z axes adopt ultra-high rigidity, high-precision roller linear guides and high-performance ball screws, with low dynamic and static friction, high sensitivity, low high-speed vibration, low-speed creep-free, high positioning accuracy, and excellent servo drive performance.

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

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

Electric spindle

The motorized spindle adopts the self-developed HSKT63 motorized spindle with built-in end tooth plate, which can realize the compound function of turning and milling. The end is equipped with a ring spray joint to cool the tool. Stepless speed regulation, built-in high-precision encoder, can achieve directional accurate stop and rigid tapping.

Turntable

The self-developed direct-drive cradle turntable is equipped with a high-precision absolute encoder and is cooled by a water cooler at a constant temperature. It has the advantages of high rigidity, high precision, and high dynamic response. The worktable adopts 8-< 14mm radial T-slots, the maximum load is 500kg (horizontal), 300kg (vertical), and the maximum workpiece diameter is ￠650.

Tool magazine

The tool magazine adopts HSKA63 manipulator disc type tool magazine, which can accommodate 24 tools

Fully closed loop feedback system

X, Y, Z linear axes are equipped with Renishaw absolute value grating scales; B and C rotary tables are equipped with HEIDENHAIN RCN2000 series absolute value angle encoders to realize full closed-loop feedback of 5 feed axes, guaranteed high precision and high precision retention.

Cooling and pneumatic system

Equipped with large flow cooling pump and water tank to provide sufficient cooling for tools and workpieces. The headstock end face is equipped with cooling nozzles, which are controlled by M code or control panel.

Equipped with a water cooler for constant temperature cooling, to ensure that the electric spindle and the direct drive turntable are in good working condition and can run efficiently for a long time.

The pneumatic system uses pneumatic components to filter, and realizes the functions of cleaning and blowing the taper hole of the spindle, air-sealing protection of the spindle bearing, turning over the tool holder of the tool magazine, and blowing the grating ruler.

Centralized lubrication system

The slide block of the guide rail and the nut of the ball screw are all lubricated with thin grease, and the lubrication is provided regularly and quantitatively to ensure the accuracy and stability of the ball screw and the guide rail.

Oil-air lubrication system

The electric spindle is equipped with imported oil and gas lubricating device, which can fully lubricate and cool the spindle. The sensor can provide abnormal lubrication alarm, which can effectively ensure that the spindle can work stably at high speed for a long time.

Workpiece measuring system

The machine is equipped with Renishaw OMP40 optical probe, used in conjunction with the OMI-2 receiver, which has strong resistance to light interference, false triggering and impact, and the measurement one-way repeatability is less than or equal to 1um (480mm/min measurement speed, using 50mm measurement needle), the applicable operating temperature is 5°C to 55°C.

Tool measuring system

The machine is equipped with Renishaw’s TS27R tool measuring system, which enables breakage detection of various tools and rapid measurement of tool length and diameter.

Five-axis precision calibration function

The machine is equipped with Renishaw’s AxiSet Check-Up Rotary Axis Line Checker kit, paired with the OMP40 workpiece measurement system, enabling machine users to quickly and accurately check the condition of rotary axes and identify problems caused by changes in temperature and humidity, machine collisions or wear and tear problems, can quickly adjust and locate performance checks, benchmark and monitor how complex machines change over time.

Machine protection

The machine adopts an integral protective cover that meets safety standards to prevent splashing of coolant and chips, ensuring safe operation and a pleasant appearance. The X-direction of the machine is equipped with an armored protective cover, which can effectively protect the guide rail and ball screw.
