Cavalry C9350/C9350C Professional Brake Center Lathe Machine

The Cavalry C9350/C9350C Professional Brake Center Lathe Machine embodies a specialized engineering approach that recognizes the distinct machining requirements of discs versus drums. Cavalry designed this machine with differentiated feed rate control strategies for each component type—discs benefit from fast and slow speed options, while drums utilize infinitely variable feed adjustment. This distinction acknowledges that rotors and drums present different cutting challenges based on their geometry, material characteristics, and functional requirements.

Three spindle speeds—70, 88, and 118 RPM—give operators broad flexibility for matching cutting parameters to specific workpieces. The lower speed range suits larger diameter components and rough cutting operations where material removal takes priority. Mid-range speeds work well for general-purpose machining across typical automotive components. Higher speeds deliver the surface quality needed for finish passes, particularly on smaller diameter workpieces where cutting speed translates directly to surface finish quality. Having three speeds rather than the conventional two-speed configuration provides greater optimization capability across diverse job requirements.

The feed system features separate calibration for rotor and drum work, reflecting the different material removal requirements of these component types. Rotor feed rates adjust from 0.002" to 0.012" (0.06-0.3mm/r), while drum feed rates range from 0.002" to 0.026" (0.06-0.66mm/r). This separation recognizes that drums typically benefit from more aggressive feed rates due to their geometry and material characteristics, while rotors often require finer feeds to achieve the surface finish standards expected in modern brake service.

The twin cutter system machines both sides of a disc simultaneously, reducing processing time and ensuring consistent surface finish across both faces. The quick changeover between disc and drum configurations minimizes setup time when switching between job types. Triangle cutting blades with positive rake geometry provide six cutting edges per blade—three usable on each side—delivering approximately 80-100 disc repairs per blade set. This translates to lower tooling costs over time compared to blades with fewer cutting edges or shorter service life.

The C9350/C9350C accommodates a practical range of workpieces common in automotive and light truck brake service. Rotor capacity spans 7" to 15" (180-381mm) with maximum thickness of 1.875" (48mm). Drum capacity reaches 17.7" (450mm) diameter with 6.875" (175mm) depth, and flywheel capacity matches the drum range. The spindle supports workpieces up to 150lbs (68kg), handling most passenger vehicle and light commercial components. The machine dimensions measure 1010x950x1150mm with gross weight of 260kg, providing substantial stability during operation.

Product highlights

Differentiated Feed Rate Control for Discs and Drums
The C9350/C9350C features specialized feed rate control that recognizes the distinct machining requirements of discs versus drums. Rotor feed rates adjust from 0.002" to 0.012" (0.06-0.3mm/r) with fast and slow speed options, while drum feed rates range from 0.002" to 0.026" (0.06-0.66mm/r) with infinitely variable adjustment. This separation allows technicians to optimize cutting parameters for each component type, improving both efficiency and surface quality.

Three Spindle Speed Options
Unlike brake lathes offering only two speeds, the C9350/C9350C provides three distinct spindle speeds: 70, 88, and 118 RPM. This expanded range allows technicians to select cutting speeds that match specific workpiece materials and conditions. The three-speed configuration gives operators more control over the machining process across different component sizes and material hardness levels, supporting both rough cutting and precision finishing work.

High-Precision Twin Cutter System
The twin cutter arrangement machines both sides of a disc simultaneously, cutting processing time and ensuring consistent surface finish across both faces. The quick changeover between disc and drum configurations minimizes downtime between different job types. Triangle cutting blades with positive rake geometry provide six cutting edges per blade, delivering approximately 80-100 disc repairs per blade set and reducing tooling costs.

Versatile Workpiece Capacity
With rotor diameter capacity reaching 15" (381mm) and drum capacity at 17.7" (450mm), the C9350/C9350C handles a broad range of passenger vehicles and light trucks. The 6.875" (175mm) drum depth accommodates deeper drums found on various applications. The 150lb (68kg) spindle weight capacity provides support for heavier components, ensuring stable operation across the full range of workpiece sizes.

Quick Changeover Configuration
The C9350/C9350C includes a quick changeover system between disc and drum setups, reducing the time required to switch between different job types. This feature is particularly valuable in busy service environments where technicians frequently alternate between rotor and drum work. The adapter system simplifies mounting and reduces setup complexity.

Long-Life Carbide Cutting Blades
Triangle cutting blades with positive rake angle design provide six cutting edges per blade—three on each side. Each blade set delivers approximately 80-100 disc repairs, representing significant cost savings compared to blades with shorter service life. The positive rake geometry contributes to efficient cutting action and reduced cutting forces, extending both tool and machine life.

Multi-Voltage Power Configuration
The motor operates on 110V, 220V, or 380V power supplies at 50Hz or 60Hz, offering flexibility for workshops with different electrical service configurations. This multi-voltage capability makes the C9350/C9350C suitable for facilities across various regions with different electrical standards.

Compact Footprint with Stable Construction
Weighing 260kg with dimensions of 1010x950x1150mm, the C9350/C9350C provides the mass needed for vibration damping while maintaining a practical footprint for workshops with limited floor space. The cast iron construction contributes to stability during cutting operations, ensuring consistent results across repeated use.
