The CMFK-DM500 Double-face grinding machine for brake discs is specifically developed for the integrated turning and grinding of brake discs. The semi-finished brake disc blank can be clamped once to complete the fine turning process of the double brake surfaces. At the same time, the double-face grinding process of the brake disc is carried out to avoid errors caused by repeated loading and unloading, which significantly reduces labor and enhances production efficiency.

CMFK-DM500 Brake Disc Double-face Grinding Machine

The equipment features a portal column design, vertical workpiece spindle, double tool holder, and vertical grinding spindle, which can be integrated with preceding and subsequent processes. It can be automated for loading and unloading by a robotic unit, or done manually. It is an optimal choice for the automotive brake disc processing industry, particularly for the batch production of small to medium-sized brake disc hub parts with diameters ranging from 100 to 450mm.
