In auto component manufacturing—from camshafts and gears to brackets and engine parts – precision, durability, and finish are essential. CUMI’s auto/ auto ancillary abrasive solutions for auto ancillary are engineered for their exacting requirements, offering reliable grinding, sanding, and finishing across automotive-grade materials.
Whether you’re machining crankshafts, deburring engine housings, or polishing braking components, our abrasives keep operations smooth, reliable, and production-ready.
Accurate shaping and dimensioning of critical engine and transmission components like shafts, gears, and valve seats.
Product Options:
Surface smoothing of die-cast or machined parts—crucial for fit, finish, and paint adhesion.
Product Options:
Final polishing of accessories, fasteners, and trim pieces for smooth aesthetics and consistent coating base.
Product Options:
Abrasive tailored to your machine type, component material, and finish requirement.
Advanced grain technology stays sharp longer—reducing wheel replacements and keeping production flowing.
Tight tolerances are maintained even under high-volume grinding of engine and transmission components.
Proven performance across two-wheeler, four-wheeler, and commercial vehicle part manufacturers.
Wheels that aren't balanced or shaped properly can fail prematurely in high-speed automation.
Use precision-balanced CUMI grinding wheels designed for high-speed grinding lines. Periodic recalibration and tool-change automation support stable performance over time.
Embedded metal particles or lubricant oils can clog the wheel, reducing grinding effectiveness.
Clean parts before grinding, choose open-structure wheels, and perform regular dressing. Ensure coolant is filtered and no debris accumulates on the wheel surface.
Poor wheel balance, worn flanges, or machine misalignment, wrong wheel grade selection can lead to chatter marks or vibration.
Always dynamically balance the grinding wheel, ensure proper flange torque, and maintain machinery alignment. Replace bearings and check runout periodically.
Use highly stable ceramic grain bonded wheels that deliver flatness control and minimal glazing—even on hard alloy materials.
Poor bonding, vibration from worn spindles, or excessive side loading can cause premature wheel breakdown.
Select high-strength ceramic or aluminum oxide-grain wheels engineered for structural stability. Maintain machine alignment, secure mounting hardware, and avoid applying side force during grinding.
