Guaranteed pitch of 100mm up to 3μ! High precision machining.

Guaranteed pitch of 100mm up to 3μ! High precision machining.

Of course, it's important that the machinery is properly maintained, and various factors such as attaching the workpiece without distortion are also crucial!

In our processing, we can guarantee a pitch of 100mm within 3μ. In recent years, there has been an increase in machine tools that have temperature control measures. This includes features like thermal friendliness and axis cooling. We also use such machines, and they do indeed provide a certain level of effectiveness. They are well-designed machines. However, even with such good machines, achieving a precision of within 3μ in normal environments is difficult. At our company, we ensure stable precision by placing these machines in a temperature-controlled room (23±1°C). To guarantee this level of precision, we have installed 3D measuring instruments, image measuring instruments, and cross-sectional shape measuring instruments within the temperature-controlled room, allowing us to measure without leaving the room. *For more details, please refer to the related links or feel free to contact us.*
