At present, we have the following requirements for the processing equipment used for ultra-precision machining

(1) high precision. This includes a high static precision and dynamic accuracy, the main performance indicators have geometric accuracy, positioning

Precision and repeat positioning accuracy, resolution, etc., such as the spindle rotation accuracy, rail movement accuracy, indexing accuracy;

(2) high stiffness. Including high static stiffness and dynamic stiffness, in addition to their own stiffness, but also should pay attention to contact stiffness to

And by the workpiece, machine tools, knives, fixtures consisting of the process system stiffness.

(3) high stability. Equipment in the transport, storage, the use of the provisions of the working environment should be long

To maintain accuracy, anti-interference, stable work. Equipment should have good wear resistance, vibration resistance and so on.

(4) high automation. In order to ensure the quality of processing, reduce the impact of human factors, processing equipment and more use of CNC system

System to achieve automation.

Multi-scale, multi-level, complex system integration of the structural design: to ensure that ultra-precision indicators.

STFF is a precision machining enterprise in China,had extensive quality assurance department equipped with CMM machine, CNC gear tester, spectrographic, metallographic and magnaflux equipment. All design and production of tools dies and molds are done in house. We use the latest technology such as CAD/CAM to assist in the design and manufacturing process.
