Introduction of 5 axis Horizontal Machine Center HMU-140P
HMU-140P adopts the horizontal moving column structure, carrying the gear transmission turntable with high rigidity and big torque and the single pendulum milling head, which is independently developed by AFMING. The whole machine frame is rigid and sensitive, easy to deal with all kinds of material parts of high-efficiency, high-precision processing requirements. The 5 axis Horizontal Machine Center HMU-140P can realized the heavy cutting vertical and horizontal conversion of five-axis simultaneously processing.
Why Choose the Our 5 axis Horizontal Machine Center?
1, Adopting a Moving Column Structure
- HMU140P horizontal five axis simultaneous machining center adopts a dynamic column structure, and the high rigidity mechanical linkage swing headswings along the X-axis to form the A-axis. The turntable rotates around the Y-axis to form the B-axis.
- The three axes are all high-precision ball screw + roller guide structures. The Y-axis counterweight is a high- precision hydraulic balance system with excellent response performance.
- Each linear axis is equipped with a HEIDENHAIN linear grating. The feed system is good, eliminating the problem of rapid wear of the Y-axis screw caused by gravity. During the system design, by increasing the natural frequency of the mechanical feed system, the cutoff frequency of the entire electromechanical drive system is increased and the lag of the mechanical feed system is reduced, which greatly increases the position loop gain KV value,effectively shortening the positioning time, minimizing and improving Contour accuracy during surface machining. The Y- xis is directly connected to the roller screw and motor. The Z/X axis is driven by a motor synchronous belt connected to a ball screw.
2, GTRT gear driven turntable swing angle milling head technology
The HMU-140P turntable adopts patented mechanical transmission GTRT technology, which achieves stronger torque output, higher rigidity stability, and better rotation accuracy than conventional turntable drives.
The A/B axis is a high-rigidity gear anti-backlash transmission, and the slewing bearing is a YRT combined roller bearing. The mechanical transmission has transmission stiffness that is unmatched by the torque motor-driven turntable. It is the best choice for processing difficult to-cut materials such as aerospace titanium alloys and high temperature alloys. The brake is a large-sized disc brake driven by high-pressure oil, which eliminates the axis deflection defect of ordinary surround brakes. It is equipped with high-precision Heidenhain linear grating as standard.

5, Using finite element analysis and dynamic optimization, greatly improves the performance of the entire machine
During design, FEA is used for dynamic optimization to achieve the optimal matching of overall structural quality, stiffness, and damping, thereby reducing the cross dynamic flexibility between the tool tip and the workpiece, improving the regenerative vibration limit during rough machining, increasing the cutting amount of rough machining, and achieving efficient cutting. At the same time, due to the reduced relative amplitude between the tool tip and the workpiece, the surface smoothness during machining is improved, the vibration speed of the tool tip is reduced, and tool wear is minimized.
The design of 5 axis horizontal machine center HMU-140P adopts finite element analysis and dynamic optimization to greatly enhance the static and dynamic characteristics of each component of the machine tool, ensuring the overall rigidity/stability and dynamic performance.
- + Whole machine FEA
- + Accurately calculate the optimal dynamic rigidity under actual working conditions
- + Improve the natural frequency and stop frequency of the feed drive system, effectively reduce positioning time and feed system lag, and achieve high response dynamic performance and high-speed machining contour accuracy
