Precision CNC Machining for Large Heavy Industry Robot Components

Precision Tolerance Control Advantage

The full range of machining accuracy is stably locked at ‌±0.02mm‌, which meets the strict matching requirements of heavy-duty industrial robot joints and high-precision transmission seats.
The constant-temperature workshop environment control eliminates the thermal deformation of large metal parts caused by temperature differences, ensuring the tolerance consistency of batch products.
The CMM full-dimensional inspection process issues a complete inspection report after each large workpiece is machined, achieving zero outflow of non-conforming products.

Full-Material Adaptation Machining Advantage

It covers the full-range material machining of aluminum alloy, structural steel, stainless steel, titanium alloy and high-strength engineering plastics, no external outsourcing is required.
For the high-hardness alloy steel commonly used in heavy-duty robots, customized exclusive tool cutting parameters are adopted, and the machined surface roughness can reach Ra0.8.
Stress relief pretreatment is carried out in advance for special materials, so that large parts have no subsequent deformation risk, and the service life is extended by 30%.

Full-Process Service Supporting Advantage

From single prototype to thousand-piece mass production, the same process standard runs through the whole process, and there is no quality difference between small-batch trial production and large-scale mass production.
Free DFM manufacturability optimization suggestions are provided, and cost-reducing and efficiency-improving implementation plans are given for the structural design of large parts.
Quick quotation response within 24 hours, conventional large workpieces are delivered within 15 days, and urgent orders can start the exclusive capacity channel for priority scheduling.
