T8445A Professional Dual-Feed SUV & Heavy-Duty Brake Drum and Disc Turning Machine
Engineered by Howann, the upgraded T8445A Dual-Feed Heavy-Duty Brake Drum & Disc Turning Machine delivers a specialized high-efficiency resurfacing solution tailored for modern automotive workshops, SUV service centers, and commercial 4x4 repair facilities. Specially optimized to handle large-diameter ventilated rotors and deep brake drums, this machine restores original micro-inch surface flatness to completely eliminate brake shudder, pedal pulsation, and noisy pad friction.
Constructed with a heavy-gauge vibration-dampening cast iron chassis weighing 260 kg, the Howann T8445A easily supports heavy workpieces up to 200 kg with machining diameters up to 450 mm. Featuring a dual-rate mechanical feed gear (0.16 mm/r for fine finishing and 0.30 mm/r for rapid roughing), 3-speed spindle rotation (30, 54, and 80 rpm), and a 4-station tool post, technicians can perform simultaneous dual-sided rotor cutting with maximum speed and dimensional precision.
Dual-Feed System (0.16 & 0.30 mm/r): Selectable dual feed rate lets operators run rapid rough cuts at 0.30 mm/r and switch instantly to 0.16 mm/r for mirror-smooth final finishing.
Upgraded SUV & 4x4 Capacity: Expanded 450 mm clearance easily accommodates thick, wide-diameter rotors from full-size SUVs, pickup trucks, and off-road vehicles.
Simultaneous Dual-Face Machining: Twin carbide cutters turn both sides of a brake rotor concurrently, ensuring perfect parallelism and cutting service time in half.
Rigid 4-Station Turret Tool Post: Heavy-duty tool holder allows fast switching between disc cutter heads and internal drum boring bars without tool disassembly.
3-Speed Torque Gearbox (30/54/80 RPM): Mechanical gear selection delivers optimal cutting torque across varying rotor alloys and hardness levels.
Machine Workflow & Operation
Arbor & Centering Setup: Mount the SUV brake disc or drum onto the rigid horizontal arbor using precision centering cones and lock rings.
Tool & Feed Rate Selection: Align the twin tool post cutters and select either roughing feed (0.30 mm/r) or finishing feed (0.16 mm/r).
Engage Automatic Power Feed: Activate the main motor and engage automatic traverse travel for hands-free, high-precision surface machining.
Inspection & Final Removal: Disengage feed upon pass completion, verify surface finish tolerances with micrometer gauges, and unload the component.
Primary Industrial Applications
SUV & Off-Road Fleet Services: Specialized reconditioning of heavy-duty vented rotors and drums for 4x4 vehicles, SUVs, and light pickup trucks.
Automotive Dealership Service Bays: High-volume disc skimming during routine brake pad replacement for passenger cars and crossovers.
Commercial Fleet Maintenance: In-house servicing of light commercial delivery vans, utility trucks, and municipal vehicle brake systems.
Brake Rebuilding Workshops: Professional reconditioning facilities refurbishing worn OEM brake drums and aftermarket rotors.
Optional Customizations & Upgrades
Motor Power Customization: Available in 1.1 kW or upgraded 1.5 kW electric motor configurations to suit high-duty shop demands.
Global Electrical Setup: Factory wired for 220V 50Hz/60Hz single-phase or 380V three-phase regional power grids.
Specialized Adapter Packs: Expanded hub adapter cone kits covering European, American, and Asian light commercial trucks.
