The video highlights the CMFK-DM500 Brake Disc Double-face Grinding Machine working on automotive brake discs in real production conditions. Filmed with emphasis on the machining cycle, it captures rough and fine turning followed by simultaneous dual-face grinding — without exposing the internal structure — showing stable motion, smooth transitions, and consistent finish quality.

Built for brake disc precision and heavy-duty loads, the Brake Disc Double-face Grinding Machine uses a dual-channel, dual-column independent feed design. This arrangement enables turning and patterned dual-face grinding in one setup, reducing total machining time by around 50% while improving parallel accuracy between disc surfaces. It is suitable for traditional steel discs as well as carbon-ceramic and aluminum-based brake discs, meeting the needs of modern automotive braking systems.

The X-axis uses a positioning moving-column structure optimized to reduce thermal distortion and absorb vibration, ensuring the Brake Disc Double-face Grinding Machine maintains accuracy even under high-speed or high-load operation. The vertical guideway layout features columns, base, and slide made from high-grade grey cast iron, with guide surfaces quenched by high-frequency treatment and coated with wear-resistant polymer. This combination ensures stable long-term accuracy and smooth feed movements.

For maximum precision, the spindle assembly employs imported P4-grade bearings with symmetrical axial and radial preloading, delivering quiet operation at high speed and consistent rotation accuracy during continuous cycles. The X, Y, and Z axes adopt a gantry-column wide-span structure, fitted with large heavy-load, high-precision linear guides and oversized long-nut ball screws. This configuration reduces transmission deformation, strengthens support rigidity, and allows rapid, powerful cutting and grinding in one machine.

The Brake Disc Double-face Grinding Machine uses diamond grinding wheels on upper and lower spindles, each powered by adjustable variable-frequency motors. This setup offers flexible speed control for various grinding processes, enabling precise surface finish adjustments and uniform grinding pressure across both disc faces. Optional CNC servo slotting tools can automatically control insert thickness and compensate for upper-lower face flatness, providing additional versatility for specialized disc designs.

Integrated CNC control features a Chinese-language LCD servo system with tool compensation, manual/automatic reference return, and real-time diagnostics. Operators benefit from a compact, fully enclosed protective design — a machine-electric-hydraulic integrated module with attractive appearance and ergonomic control layout. The sealed enclosure prevents debris from escaping, keeping the work area cleaner and improving safety.

Suitable for automotive, machinery, motor manufacturing, and gear industries, the Brake Disc Double-face Grinding Machine handles long-term, high-load precision machining of discs and gear-like parts. It can support small- to medium-batch multi-variety production or join automated lines for high-volume manufacturing. The combination of optimized structure, precision spindle, and diamond wheel grinding ensures consistent parallelism, surface smoothness, and dimensional accuracy — all essential for brake disc performance and longevity.

In the video, viewers can see seamless coordination between turning and dual-face grinding operations, with the grinding wheels moving in opposite directions to achieve uniformly smooth disc faces. The process enhances brake performance by ensuring flat, parallel contact surfaces and improves production efficiency through reduced cycle time. With high rigidity, precision control, and environmental protection, Hengga Intelligent's CMFK-DM500 Brake Disc Double-face Grinding Machine offers manufacturers a powerful, adaptable solution for brake disc machining in demanding industrial environments.
