The high-precision and stable performance of the HMV-860/860A/1060 series vertical machining centers from Hanmo Industry stems from the synergy of their structured design optimization and core technical parameters.

Through Y-shaped symmetrical structure, finite element analysis optimized castings and split feed systems, this series has achieved micron-level precision control in heavy cutting scenarios, providing quantifiable processing solutions for the high-end manufacturing field.

I. Structural Design: Technical Realization of Rigidity and Thermal Stability

1. Optimization of infrastructure

The series adopts a symmetrical design of box-type columns and bases, reinforced with cross rib plates. After finite element analysis verification, the structural rigidity is increased by more than 40% compared with the traditional design. All major castings are made of high-quality cast iron and undergo overall aging treatment to eliminate internal stress, ensuring dimensional stability during long-term processing.

2. Feed guidance system

The X, Y and Z axes adopt a split ball screw layout to shorten the length of the transmission chain and reduce vibration. The guide rail adopts roller-type linear guide rails (X and Y axes are optional), and stable clamping is achieved through bolt pre-tightening, avoiding the friction force fluctuation problem of the traditional conical strip design.

3. Thermal deformation control

The spindle penetration cooling device (excluding the tool) and the heat exchanger form a closed-loop temperature control system, keeping the temperature rise of the spindle within 3℃ during continuous processing. The symmetrical column design compresses the accuracy deviation caused by environmental temperature fluctuations to 0.002mm/m through a uniform heat dissipation path.

Ii. Spindle and Tool System: Parameter Support for Efficient Cutting

1. Spindle performance

It is equipped with an 8000rpm belt-driven spindle as standard, with an output torque of 47.7N · m, which can meet the requirements of 7.5mm depth face milling of S45C steel, and the chip discharge rate reaches 367cc/min.

Optional 12,000-24,000 RPM direct drive/built-in spindle, suitable for high-speed processing of light metals such as aluminum alloy, with the maximum chip removal rate of the end mill reaching up to 1206cc/min.

2. Automatic tool changing device

It adopts a cam-type tool magazine design, with a capacity of 24/30 tools, supporting random tool selection, and the tool change time is ≤1.5 seconds. The maximum diameter of the cutting tool can reach 150mm (when the adjacent tool position is empty), and the weight limit is 7kg, which is suitable for multi-process compound processing requirements.

Iii. Precision Control: Quantitative Verification from Parameters to scenarios

1. Dynamic accuracy guarantee

Equipped with Fine Surface Control (FSS) and Smooth Tolerance Control (STC) functions, through 1-micron increment instructions and path error compensation algorithms, the surface roughness of curved surface processing is stabilized below Ra1.6, and the processing time is shortened by 15%.

2. Typical application data

Aerospace parts (alloy 7075-T6, 430×430×80mm) : After 8 hours of continuous processing, the form and position tolerance is ≤0.01mm;

· Precision mold (P20 steel, 420×360×60mm) : Completed in 7 hours, with the cavity size accuracy controlled within ±0.005mm.

The HMV series has established a technical benchmark for precision machining through the in-depth integration of structured design and parameter optimization. Its application performance in fields such as aerospace and mold manufacturing has confirmed the technological accumulation of Hanmo Industry in the field of vertical machining centers.
