High-precision jig grinding machine JJG-540 CM CNC

The jig grinding machine is the top choice for processing high-precision flat surfaces, irregular shapes, and round holes. The jig grinder is very similar to a jig borer, in that the table positioning and spindles are very accurate (far more than a manual milling machine or lathe).It is almost used by tool and die makers in the creation of jigs or mating holes.

Thank you for your strong support and trust in Chien Wei for many years. If you purchase PH10 3D CNC CMM of any configurations from today, you will be given the automatic styli changer and styli module provided by RENISHAW free of charge, which will help you greatly improve the measuring accuracy of CMM and prolong its service life and will not bring you any additional costs.

"Changer" Example "Changer" Promotional kits are shown below. Please note that the ACR3 offer is a "half price" not free of charge. As previously mentioned we can create additional offer kits where the monetary value is similar but these must be agreed in advance with CMM Marketing who will also allocate a kit part number.
