The video features Hengga Intelligent's CMFK-DM500 Brake Disc Double-face Grinding Machine in full operation on automotive brake discs. Captured in real production conditions, the footage focuses solely on the machining process—rough and fine turning followed by dual-face grinding—without revealing the internal mechanisms, highlighting the smooth and stable motion during both precision and high-efficiency work.

The Brake Disc Double-face Grinding Machine uses a dual-channel, dual-column independent feed structure, allowing simultaneous processing of both brake disc surfaces. This configuration combines precision turning and patterned grinding in one cycle, reducing overall machining time by approximately 50% while improving parallelism between disc faces. It is ideal for standard discs and newer materials such as carbon-ceramic and aluminum-based brake discs, meeting the growing demand for high-performance automotive braking components.

A high-speed motor ensures excellent results in both low- and high-speed cutting for light or heavy loads. The X and Z feed axes feature premium linear guide designs that deliver rapid movement, high precision, and low wear. Heavy-load type slide tables paired with high-rigidity linear rails allow the Brake Disc Double-face Grinding Machine to perform strong cuts and maintain accuracy during extended runs. Servo motor-driven feed shafts mounted on linear bearings reduce power consumption while keeping structural stiffness up to demanding production standards.

The machine operates with the reliable KND dual-channel CNC system, enabling simultaneous control of turning and grinding heads. For grinding operations, the main spindle adopts AC variable-frequency stepless speed control, giving operators flexibility to match different grinding processes and materials. The ergonomic sealed sheet-metal enclosure is designed for operator comfort, environmental protection, and reduced particle spread, keeping the work area clean by preventing chips and debris from escaping.

Adjustments and transport are made easier by spiral leveling wedge pads and leg-type base supports. This design simplifies machine leveling and relocation, making production setup faster and more practical. The Brake Disc Double-face Grinding Machine can be deployed as a standalone system for mass production or integrated into automated lines with other equipment, enabling manufacturers to tailor workflows based on variety and volume requirements.

Beyond brake discs, the Brake Disc Double-face Grinding Machine is suitable for producing wheel drums, brake drums, engine end covers, flywheels, flanges, and other disk-type components. Its robust construction, high-rigidity columns, and optimized feed mechanism allow it to adapt to the dimensional and finish requirements of diverse parts while maintaining operational efficiency.

As captured in the video, the transition from precision turning to dual-face grinding is seamless, with both grinding wheels moving in opposing directions to achieve uniform surface quality on both sides of the brake disc. This not only enhances braking performance by improving contact consistency but also extends component lifespan by maintaining tighter tolerances and smoother finishes. Operators benefit from the stable feed motion, reduced vibration, and predictable output characteristics, reinforcing the machine's performance in mass production environments.

With its blend of high rigidity, accurate dual-face processing, and operator-centered protective design, Hengga Intelligent's CMFK-DM500 Brake Disc Double-face Grinding Machine demonstrates how well-engineered machinery can shorten production cycles, improve parallel accuracy, and deliver superior disc surface finish—all while meeting safety and environmental standards essential for today's automotive manufacturing.
