PETER WOLTERS AC 400 double-side batch processing machine has been designed for high-precision series processing work pieces. Due to its modular construction, AC 400 can be used as a fine grinding, lapping, honing, deburring, and polishing machine.

Like all machines of the AC microLine ® series, AC 400 is based on tried and tested core components such as high-precision, pneumatic pressure system, non-contact micro measuring controller, powerful drive technology, and the PLC control. Software has been developed by PETER WOLTERS which makes it possible to intuitively operate the machine entirely by menus. The upper wheel moves approx. 500 mm upwards. This and the design of the entire machine base allow comfortable access from three sides to the process area.
