CUMl’S Camshaft wheels offer good form holding, free cutting ability while maintaining the stringent geometrical and surface finish requirement to maintain consistent and tight surface finish tolerances. CUMl‘s versatile camshaft wheels can grind materials like forged steel and chilled cast iron with highest amount of stock removal without thermal damage on the cam flank. CUMI also offers single wheel for both roughing and finishing operations

Product Description

CUMI Camshaft Grinding Wheels are engineered to deliver precise cylindrical grinding for Auto & Auto-Ancillary engine components, ensuring consistent camshaft performance, durability, and smooth rotation. Designed for OEM-level production, these vitrified-bond wheels help automotive suppliers achieve tight tolerance control across cam lobes, flanks, and journals during high-speed grinding processes.

To simplify wheel selection, CUMI provides a Good – Better – Best pairing chart for materials such as Case Hardened Steel, Nodular Iron, and Chilled Cast Iron—helping grinding engineers pick the right hardness grade to optimize cost-per-component, dressing interval, and form retention.

Feature → Advantage → Benefits

Sharp & Friable Aluminium Oxide Grains → self-sharpen during grinding → high stock removal without burning the cam flank
Vitrified Bond System → maintains wheel structure under pressure → avoids premature breakdown and extends wheel life
Uniform Density & Hardness Across Diameter → ensures balanced rotation → prevents chatter marks, taper errors, and surface vibration
Single Wheel for Roughing & Finishing → eliminates multi-wheel setup → reduces cycle time and boosts production output
Stable Form & Dimensional Accuracy → holds shape on long production runs → ensures reliable cam profile performance inside engine assemblies

Ideal for cylindrical grinding machines running large batches of camshafts in automotive engine manufacturing and regrinding operations.

FAQs

01.

Which industry commonly uses this wheel This wheel is primarily used in the Auto & Auto-Ancillary sector, especially camshaft component manufacturing plants and regrinding centers.

02.

Can one wheel perform roughing and finishing? Yes — CUMI provides a dual-purpose wheel that performs both stages without requiring a changeover.

03.

Which materials can it grind effectively? It supports forged steel and chilled cast iron without thermal distortion or cam flank burn.

04.

How does it support tight tolerance grinding? The vitrified Krystal bond and uniform density ensure stable form retention, minimizing deviation on cam lobes and journals.

05.

How does this improve production cost per component? Its high stock removal rate and long wheel life reduce dressing frequency and increase parts produced per wheel.
