The CMFK-DM500 double-face grinding machine for brake discs is specially designed for the integrated turning and grinding processes of brake discs. This machine enables a single clamping of semi-finished brake disc blanks to complete the fine turning of both brake surfaces. Concurrently, it performs the double-face grinding process, effectively preventing errors caused by repeated loading and unloading. This significantly reduces labor costs and boosts production efficiency.
The machine features a portal column design, a vertical workpiece spindle, double tool holders, and a vertical grinding spindle, allowing seamless integration with upstream and downstream processes. It supports automated loading and unloading via robotic units or can be manually operated. This equipment is an optimal solution for the automotive brake disc processing industry, particularly for batch production of small to medium-sized brake disc hub parts with diameters ranging from 100 to 450mm.
Main Features of CMFK-DM500 Brake Disc Double-Face Grinding Machine
1. The CMFK series brake disc grinding machine’s lathe bed is constructed with a thermally symmetrical box-type reinforced cast iron structure made from HT300 gray cast iron, minimizing thermal deformation while providing robust support for heavy cutting operations.
2. The workpiece spindle unit boasts a high-stiffness bearing support structure, ensuring excellent rigidity and high rotational accuracy. The entire spindle system features a long lifespan, low temperature rise, good accuracy retention, and ease of maintenance.
3. The machine employs a double-column double-feed structure, with each column equipped with X, Z, and Y feed axes. The use of long heavy-duty roller sliders guarantees the equipment’s rigidity and operational stability.
4. The twin Z-axes are designed with a vertical column structure, and the numerical control system operates independently through a dual-channel mode.
5. The grinding head assembly utilizes a dual-surface grinding mode for the brake disc, featuring a torque self-sensing function that automatically adjusts the feed speed based on the workpiece’s remaining material, ensuring processing efficiency and stability.
6. The internal structure features vertical and steep-sloped chip removal designs, with the entire interior lined with stainless steel chip guide plates. This design reduces thermal deformation caused by localized heating from chip accumulation, ensuring the continuous processing accuracy of the brake disc grinding machine.
The CMFK-DM500 CNC vertical grinding machine excels in integrating with automatic production lines for product processing. It features automatic clamping for precise finishing of double brake surfaces and disk surface grinding.
This machine adopts a double-column double-feed structure, with the numerical control system operating autonomously through a dual-channel mode. Each column is equipped with X, Z, and Y feed axes, and the grinding head assembly employs a dual-surface grinding mode. The torque sensing function allows the system to automatically adjust the feed speed according to the workpiece’s remaining material, ensuring both processing efficiency and accuracy.
