Product Description

Precision processing technology system

Sanluo Precision Factory has a well-developed precision NC machining technology system. The turning accuracy is IT6, the roundness is 0.002mm, and the coaxiality is 0.005mm. The milling accuracy is IT7 level, the flatness is 0.01mm, and the positional accuracy is 0.015mm. The grinding accuracy is IT5 level, the cylindricality is 0.001mm, and the surface roughness is Ra0.2μm. Through the combination of precision turning, precision milling, precision grinding, and precision boring processes, micro-metric processing accuracy is achieved. In terms of temperature control environment guarantee, there is a constant temperature workshop, with the temperature controlled at 20±0.5℃ and the humidity controlled at 50±5%RH. The foundation of the machine tools is treated with vibration isolation to reduce external vibrations. Before processing the workpieces and tools, they are pre-set at a constant temperature to eliminate the influence of temperature differences. Thus, the precision processing accuracy is not affected by the environment, and the batch production is also consistent.

Error compensation technology

As a professional precision CNC machining manufacturer, Sanluo Precision Company adopts online measurement technology in precision nc machining. The machine tools are equipped with laser probes and trigger probes. During the machining process, the dimensions of the workpiece can be measured in real time, and the compensation for tool wear and thermal deformation can be automatically carried out based on the measurement results. The company has mastered many error compensation technologies. Through the compensation of machine tool geometric errors, systematic errors such as the straightness of the guide rails and the vibration of the spindle are eliminated. Thermal error compensation is adopted, and the thermal deformation is corrected in real time using the data from temperature sensors. The company has provided tens of thousands of customized NC machining services for precision industries such as optics, medicine, and metrology, with a qualification rate of precision above 99.5%.
