Product Description
Maximize Shop Efficiency with Howann C9350: Dual-Motor Independent-Feed Brake Drum & Disc Resurfacing Workstation
Engineered by Howann, the C9350 Dual-Motor Brake Drum & Disc Resurfacing Workstation delivers a heavy-duty, versatile machining platform designed for busy auto repair centers, commercial fleet bays, and brake reconditioning specialists. By separating the spindle torque drive from the feeding mechanism, this advanced machine eliminates feed hesitation and gear-driven chatter marks, restoring original OEM micro-inch finishes across grooved rotors and worn drums in a single efficient setup.
Built upon a massive 330 kg vibration-absorbing cast-iron base, the Howann C9350 handles heavy brake components without structural deflection. The machine combines a 3-speed belt transmission system (70, 80, and 118 rpm) for maximum cutting torque on tough carbon alloys with an independent DC-powered infinitely variable feed system (0-0.4 mm/r). This dual-motor setup allows operators to fine-tune rotation speed and travel speed independently, eliminating Disc Thickness Variation (DTV) and high-speed brake pedal pulsation.

Core Features & Engineering Highlights
- Dual Independent Motor Drive: Separate drives for spindle rotation and axis traverse eliminate transmission lag and mechanical resonance during heavy roughing passes.
- Infinitely Variable DC Feed (0 -0.4 mm/r): Electronic DC governor permits operators to fine-tune the cutting feed speed on the fly to suit specific rotor material hardness.
- Heavy-Duty 450 mm Drum Clearance: Generous working window easily accommodates wide-diameter commercial delivery van and light truck rear brake drums up to 160 mm deep.
- 3-Speed Torque Adjustment (70/80/118 RPM): Belt-pulley gear setup ensures high low-speed torque for large drums and high cutting velocity for small-diameter rotors.
- 330 kg Vibration-Dampening Cast Body: Industrial cast iron chassis absorbs mechanical chatter, protecting carbide cutter tips and producing micro-smooth finishes.
Machine Workflow & Operation
- Arbor Mounting & Centering: Lock the brake drum or rotor onto the rigid main spindle arbor using precision ground centering cones, dampening bands, and quick-lock nuts.
- Spindle Speed & Feed Tuning: Select the belt speed setting (70, 80, or 118 rpm) and dial the DC feed knob to the desired cross-travel feed rate.
- Engage Dual-Motor Cutting: Start the 0.75 kW main spindle motor and activate the independent DC feed for smooth, hands-free automated machining.
- Inspection & Unloading: Measure parallel flatness and surface finish micro-inch tolerances with micrometer gauges, then dismount the refinished component.
Primary Industrial Applications
- Medium & Heavy Auto Repair Depots: High-precision rotor and drum reconditioning for light commercial trucks, SUVs, and passenger cars.
- Commercial Fleet Maintenance Depots: In-house brake servicing for delivery vans, municipal utility trucks, and emergency transport fleets.
- Brake System Remanufacturing Workshops: Industrial reconditioning centers refurbishing worn OEM brake drums and aftermarket rotors back to factory specs.
- 4S Dealership Service Bays: Premium solution for diagnosing and resolving customer brake pedal shudder and thermal glazing complaints.
Optional Customizations & Accessories
- Commercial Truck Adapter Packs: Expanded hub adapter rings and large centering cones for light commercial trucks and European vans.
- Multi-Voltage Power Supply Setup: Factory pre-wired for 110V/220V single-phase or 380V three-phase regional electrical grids.
- Anti-Vibration Silencer Belts: Heavy rubber dampening belts and spring silencer bands for high-resonance thin-web rotors.
Frequently Asked Questions (FAQ)
Q1: How does the dual-motor design on the Howann C9350 improve cutting results?
By using an independent DC motor for feed traverse, cutting movement remains entirely isolated from spindle load fluctuations, eliminating feed hesitation chatter marks on the friction surface.
Q2: Can the Howann C9350 process large commercial vehicle brake drums?
Yes. The C9350 accommodates brake drums up to 450 mm in diameter and 160 mm in depth, making it ideal for SUVs, pickup trucks, and light commercial vans.
Q3: What after-sales warranty and international safety standards are included?
Howann C9350 equipment complies with international CE safety standards and includes a 1-year comprehensive factory warranty, video outgoing inspection reports, and full remote technical guidance.
