Precision Cut-off Wheel without Reinforcing Mesh

Precision cut-off wheels are resin-bonded wheels designed for accurate, burr-free cutting of thin-walled sections, tubes and small-diameter metal workpieces. Their fiberglass-mesh-free structure provides efficient cutting and clean edges for precision applications in automotive, aerospace and general metal fabrication. High sharpness and reduced material loss make them suitable for high-quality cut-off operations.

Key Features

High Precision

Engineered for straight, smooth cuts with minimal burr formation, ensuring excellent surface quality and dimensional accuracy.

Mesh-free Design

Eliminates fiberglass mesh, allowing for narrower kerf width, reduced power consumption, and cleaner cutting action.

High Sharpness and Long Service Life

Optimized abrasive grain and bond formulation deliver fast cutting speed while maintaining consistent performance throughout the wheel's service life.

Our Advantages

1. Exceptional cutting accuracy with minimal burrs and heat generation protects workpiece integrity.

2. Mesh-free construction enables thinner wheels (1.2 mm), reducing material waste and energy consumption.

3. Stable, reliable performance across a wide range of ferrous and non-ferrous metals.

4. Low noise and vibration improve operator comfort and safety.

Applications

1. Precision cutting of stainless steel tubes, pipes and thin sheets.

2. Cutting carbon steel, aluminum, copper and non-ferrous metal sections.

Suitable for automotive parts, aerospace components and general fabrication workshops.

Product Applications and Cutting Performance

The 255 x 1.2 x 31.75 mm SA80 precision cut-off wheel uses SA special alumina abrasive, a resin bond and an ultra-thin, mesh-free design with a thickness of 1.2 mm. Optimized for precision component cutting, it provides the following performance:

High precision and low material loss: the ultra-thin wheel produces a narrow kerf, reducing waste when cutting valuable metals such as special steels and alloy tool steels while maintaining dimensional accuracy. The thin design also enables lighter, smoother cutting, minimizing the heat-affected zone, burrs and burns.

Smooth, clean cut surface: on dedicated precision cutting machines, the wheel runs stably at high speed and produces flat, smooth cut faces that often need no secondary finishing and are suitable for direct precision assembly.

Sharpness and durability: the SA80 abrasive formulation balances sharpness and service life, efficiently cutting heat-treated steels such as hardened steel and bearing steel while maintaining consistent performance.

Typical Applications and Examples

This wheel is particularly suitable for precision components requiring high dimensional accuracy and excellent cut-face quality. Typical applications include:

1. Automotive precision components: cutting engine parts, transmission components and sensor brackets. Manufacturers such as Shanghai Hino Motors, Toyota Motor Corporation and Mitsubishi Motors frequently use this type of wheel for efficient, low-damage cutting of small alloy steel and tool steel parts, supporting the precision and reliability needed for subsequent assembly.

2. Mold and tool manufacturing: cutting high-hardness alloy tool steels, including SKD and SKS grades, for drills, taps, ejector pins, mold inserts and punches. It is also used to cut test bars or section hardened steel samples for metallurgical analysis.

3. Metallurgical material analysis: laboratory metallographic sectioning extracts small specimens from larger workpieces with minimal deformation, preserving the original microstructure and metallurgical phases.

4. General mechanical components: high-volume precision cutting of shafts, pins, springs and irregular sections with consistent dimensions across production batches.

Applicable Materials

With its SA abrasive and 80-grit specification, this wheel is primarily suitable for:

Hardened steel, bearing steel and high-speed steel (SKH)

Alloy tool steels (SKS, SKD)

General carbon steel and spring steel

Special steels

Use dedicated precision cutting equipment and strictly observe the maximum safe operating speed marked on the wheel, typically approximately 3,420 m/min, for optimal performance and safe operation.
