Brake Disc Custom CNC lathe Machine

The machine body is integrally cast from high-strength HT300 cast iron and undergoes natural aging followed by secondary stress-relief treatment to minimize residual internal stresses and reduce the risk of deformation or loss of accuracy during long-term continuous machining. The machine uses a vertical turning structure, which is well suited to brake disc machining. The workpiece is positioned vertically and naturally rests against the fixture locating surface under its own weight, helping to reduce deformation caused by uneven clamping forces. This structure helps maintain key brake disc quality requirements, including parallelism between the two faces, end-face runout, and thickness variation, while reducing the risk of braking vibration and abnormal noise after installation.

The core transmission and feed system uses a heavy-duty spindle unit with high-precision matched bearings and a constant-temperature lubrication system. This design helps control temperature rise and maintain stable spindle operation under high loads, allowing the machine to handle the heavy cutting loads associated with brake disc roughing over extended periods. The X- and Z-axis feed systems feature widened guideways combined with precision preloaded ball screws, providing responsive feed movement, high positioning accuracy, and good repeatability. This allows the machine to perform stable, high-precision turning of brake discs ranging from small automotive components to larger discs used in construction machinery. The fully enclosed machine structure provides protection against coolant and metal chips, helping maintain stable operation in demanding workshop environments.

The Brake Disc Custom CNC lathe Machine can complete multiple machining operations in a single clamping setup, reducing the need for repeated re-clamping and re-alignment. A single machine can perform a range of brake disc machining operations, including end-face turning, external and internal cylindrical turning, boring, chamfering, filleting, grooving, and surface finishing. This helps reduce cycle time, manual intervention, and positioning errors caused by repeated clamping. For customized, irregularly shaped, and non-standard-sized workpieces, the CNC system supports flexible programming, parameter storage, and program reuse for batch production, simplifying setup for different workpiece specifications. The machine can be configured with either a horizontal eight-station turret or a vertical turret according to the required machining processes and production capacity.

The machine features a large-angle inclined chip-removal structure with an enlarged chip discharge area, allowing chips generated during turning to fall away from the machining zone and reducing the risk of accumulation and blockage. An automatic chip conveyor can be added for continuous chip removal. The standard 20-inch waterproof hydraulic chuck provides uniform and adjustable clamping force, allowing workpieces to be securely held without unnecessarily damaging their surfaces. It can accommodate brake discs with different thicknesses and outer diameters, supporting quick workpiece setup. The electrical system uses Schneider Electric components, with an organized cabinet layout and appropriate protection measures to support reliable operation and reduce the risk of electrical faults.

Our company has more than ten years of experience in CNC machine tool manufacturing. We operate our own foundry, precision assembly facility, and testing laboratory, allowing us to independently handle key processes including machine bed casting, spindle assembly, and precision calibration. By maintaining control over critical manufacturing stages and reducing reliance on outsourced semi-finished components, we ensure consistent equipment quality and reliability.
