Howann C9365 Heavy-Duty Brake Disc Lathe with 650 mm Drum Capacity, 480 kg Cast Body, and Dual Electric Power Feed

Engineered by Howann, the C9365 Heavy-Duty Commercial Brake Drum & Disc Resurfacing Lathe provides an industrial-grade machining station built specifically for high-volume commercial truck repair centers, municipal transit bus depots, and heavy transport fleet workshops. Designed to withstand the extreme mechanical forces generated when turning heavy-cast commercial brake components, this machine restores original flat parallel tolerances across warped truck brake drums and high-tonnage ventilated rotors, permanently resolving severe brake shudder, glazing, and uneven pad friction.

Constructed on a heavy-gauge 480 kg shock-dampening cast iron frame, the Howann C9365 eliminates harmonic chatter during heavy material removal passes. Featuring a 3-speed gear transmission (30, 49, and 88 r/min) driven by a 1.1 kW high-torque electric motor, the lathe combines an extended 256 mm tool carriage stroke with dual independent electric power feeds. This motorized feed mechanism allows infinitely variable travel speeds in either axis direction, delivering mirror-smooth micro-inch finishes across both inner drum walls and dual rotor friction faces concurrently.

• 650 mm Extra-Large Drum & 480 mm Disc Clearance: Massive working window easily accommodates wide rear brake drums and large-diameter rotors from heavy commercial trucks, trailers, and coaches.
• 480 kg Ultra-Rigid Cast Body: Heavy industrial chassis absorbs cutting resonance, protecting carbide tool bits and eliminating chatter marks on hard carbon alloy rotors.
• Dual Independent Electric Power Feed: Motorized feed drives offer infinitely variable tool travel speed in both longitudinal and transverse axes for superior surface roughness control.
• Extended 256 mm Tool Carriage Stroke: Long carriage travel allows complete single-pass machining on deep commercial drums and extra-wide hub assemblies without re-clamping.
• Simultaneous Dual-Face Disc Skimming: Twin tool post turns both sides of a brake rotor concurrently, ensuring absolute parallel alignment and halving labor times.

• Workpiece Mounting & Centering: Secure the commercial brake drum or rotor onto the heavy spindle arbor using specialized heavy-truck centering cones and locking collars.
• Speed Selection & Tool Positioning: Select optimal spindle torque speed (30, 49, or 88 rpm) and position tool bits against the friction surfaces.
• Engage Dual Electric Power Feed: Activate the 1.1 kW spindle drive and dial in the electric feed velocity for smooth, hands-free cross-feed machining.
• Quality Inspection & Dismounting: Measure finished surface parallelism and surface micro-finish tolerances with micrometer gauges, then unload the component.

• Heavy Commercial Fleet Depots: In-house reconditioning of heavy truck, semi-trailer, and intercity bus brake drums and rotors up to 650 mm.
• Municipal Transit & Emergency Vehicle Maintenance: High-precision brake servicing for public city buses, fire trucks, and municipal utility fleets.
• Commercial Trailer Repair Centers: Specialty machining of heavy trailer brake drums and hub-integrated rotor assemblies.
• Brake Component Remanufacturing Outlets: Reconditioning worn OEM commercial brake components back to factory operational specs.

• Commercial Heavy Truck Adapter Kits: Expanded hub adapter rings and large centering cones tailored for European, American, and Asian heavy commercial vehicles.
• Multi-Voltage Power Supply Setup: Factory pre-wired for 220V, 380V, 415V, or 440V (50/60 Hz) regional industrial power grids.
• Heavy-Duty Carbide Cutter Tip Upgrades: Premium multi-edge indexable tungsten carbide insert packages for tough high-carbon alloy drums.
