In the field of high-end precision manufacturing, the dual requirements of "micron-level accuracy" and "long-term stability" have always been the core yardstick for measuring the technical strength of processing equipment.

At present, in the processing demands of domestic precision molds, small aerospace components and other fields, approximately 60% of high-precision processes still rely on imported vertical machining centers. The core bottleneck lies in:

Traditional equipment is hard to balance "high-rigidity cutting" and "low thermal deformation". During continuous processing for more than 12 hours, the precision deviation often exceeds 0.01mm. Moreover, the cost of a single imported device exceeds 8 million yuan, and the technical service response cycle is as long as 72 hours.

Hanmo Industry has been deeply engaged in the field of precision processing equipment, solving industry pain points through structured technological innovation. Its core product, DMC-650, has achieved breakthroughs in dimensions such as rigid design, thermal control accuracy, and dynamic response, redefining the technical benchmark for domestic high-end vertical machining centers.

I. Structural Rigidity: Design Innovation from "passive seismic resistance" to "active deformation resistance"

In precision machining, the rigidity of the equipment structure directly determines the accuracy stability during heavy cutting.

Hanmo adopts a box-type portal frame integrated structure. Through FEM finite element analysis to optimize the layout of the stiffening plates, the overall rigidity of the machine is increased by 45% compared to the traditional design. In the 7.5mm depth face milling test of S45C steel, the vibration amplitude of the spindle is controlled within 0.002mm, and the surface roughness is stable at Ra1.6. It is 30% better than the industry average.

Its short spindle extension design further reduces the machining sag:

The distance between the main shaft and the sliding surface has been shortened to 520mm, and it is compatible with 45 # roller type linear guides (with rigidity increased by 145% and thrust increased by 190%).

Achieve positioning accuracy of 0.001mm within a 650mm stroke

It is perfectly adapted to the high-speed milling requirements of precision mold cavities (such as P20 steel 420×360×60mm molds).

Ii. Thermal Control System: A closed-loop technology that locks "temperature fluctuations" at the micrometer level

Thermal deformation is the "invisible killer" of precision machining.

Hanmo innovatively adopts a full-domain oil cooling closed-loop system. Through rapid oil temperature control (with an accuracy of ±0.1℃) and internal circulation cooling of the spindle head, the temperature rise of the entire machine during continuous processing is compressed to within 0.5℃. Actual measurements show that

Under the working condition where the ambient temperature fluctuates by ±5℃,

The equipment continuously processes aluminum alloy 7075-T6 parts (φ100×55mm) for 24 hours, with a shape and position tolerance deviation of only 0.003mm, which is 75% higher than that of traditional equipment (deviation 0.012mm).

Meanwhile, the spindle adopts a direct-coupled design and an oil-gas lubrication system. The thermal equilibrium time at 15,000 RPM is shortened to 15 minutes, and the thermal deformation is controlled at 0.001mm/100mm, solving the industry problem of "precision drift" during high-speed cutting.

Iii. Dynamic Accuracy: Full-chain Optimization from "Path Error" to "Surface Quality"

In complex curved surface processing, the smoothness of the tool path directly affects the surface quality.

Hanmo equipment is equipped with Fine Surface Control (FSS) and Smooth Tolerance Control (STC) systems. Through 1-micron increment instructions and path error compensation algorithms, the step difference in surface processing is controlled within 0.5 microns.

In the processing of aerospace pneumatic components (stainless steel 150×150×25mm), it only takes 20 hours to complete the process that would take 30 hours with traditional equipment, and the surface roughness reaches Ra0.8.

Its cam-type automatic tool changing system with a capacity of 24 tools has a stable tool changing time of 1.8 seconds. Combined with the rigid tapping function (M30 thread processing accuracy IT6 grade), it achieves seamless connection from milling to tapping, and the efficiency of multi-process compound processing is increased by 40%.

Iv. Industry Value: A Domestic Breakthrough from "Equipment Substitution" to "Standard Output"

Hanmo's technological breakthroughs are rewriting the cost and efficiency rules of precision manufacturing:

Its equipment procurement cost is 40% lower than that of imported equipment, and the technical response cycle is shortened to 24 hours. It has been serving leading domestic mold enterprises and aerospace supporting manufacturers.

In a certain precision gear mold processing project for new energy vehicles, Hanmo Equipment compressed the processing cycle of a single set of molds from 15 days to 7 days, and increased the qualification rate from 82% to 99.5%, directly boosting the customer's mass production efficiency by 50%.

This practice of "defining reliability based on technical parameters" not only broke the foreign monopoly in the field of precision processing equipment, but also established domestic technical standards through over 120 core patents, providing an "independent and controllable" underlying support for China's precision manufacturing industry.

Today, as precision manufacturing advances towards the "sub-micron level", Hanmo Industry has demonstrated through structured innovation that domestic high-end processing equipment has the technical strength to move from "catching up" to "keeping pace". Every 0.001mm breakthrough in precision is a solid footprint for China's manufacturing industry as it moves towards becoming a "smart manufacturing power".
