How about our DMU400 Five-axis Simultaneous Machining Center ?
The DMU400 five-axis simultaneous machining center adopts a cantilever structure and is equipped with the DD drive cradle-type rotary worktable independently developed by AFMING.
It has excellent rigidity, fast response, and stable accuracy, and can easily handle the efficient processing of small precision parts such as medical equipment and new energy sources.
DMU400 Five-axis Machining Center Advantages：
1, The three axes are cantilever structures
The DMU400 five-axis linkage machining center adopts a reinforced cantilever structure. And the X/Y/Z axes are placed on the upper part of the bed. In addition, the basket turntable rotates around the Y-axis as the B-axis and around the Z-axis as the C-axis.
- + X/Y/Z axes are all driven by high-response nut rotating ball screws, which effectively prevents thermal extension of the screws and ensures accuracy and stability.
- + The cradle-type rotary table is designed and manufactured by our company. The B/C axes are all driven by DD motor direct drive, with oil cooling circulation as standard. The brakes use high-pressure oil to drive large-size disc brakes, with high precision and long life.
- + X/Y/Z axes all use high-rigidity 35-type P-level roller guides to reduce friction and improve accuracy.
- + X/Y/Z axes all use ball screws with a diameter of 40mm, a lead of 20mm, and a rapid movement speed of 40m/min.
Acceleration 1G.
- + The Z-axis adopts high-precision, high-speed air pressure counterweight, which responds efficiently, effectively eliminates the influence of gravity, reduces the thermal elongation of the screw rod, and effectively improves the service life and accuracy of rolling parts.
2, High rigidity electric spindle
the 5 axis machining center is equipped with 20000 rpm electric spindle HSKA68、BBT40. Hence it fully considers special processing conditions such as various parts processing and mold processing, and provides customers with customized spindle solutions to expand the processing range. Improve processing efficiency.
- + Permanent magnet synchronous double coil spindle technology saves more than 12% of energy.
- + More stable axial dimensions.
- + HSK- A63 shaft end interface, high precision, high rigidity, high speed.

| 20/25 kW | Power (S1/S6-40%) |
| 48/60 N.m | Output torque(S1/S6-40%) |
3, Finite element analysis and dynamics optimization are used to greatly improve the performance of the entire machine.
- + Dynamic optimization through FEA, effectively improve the anti-vibration of the whole machine.
- +Accurately calculate the optimal dynamic rigidity under actual working conditions.
- +Improve the natural frequency and cutoff frequency of the feed drive system, effectively reduce the positioning time and the lag of the feed system to achieve high response dynamic performance and high- speed machining profile accuracy.
