What factors affect the service life of cutting and polishing wheels?
Jul 17,2026
1. Materials and specifications of the consumables themselves
Abrasive type
White corundum and brown corundum have good toughness, are suitable for ordinary carbon steel, and wear slowly; single crystal corundum has higher wear resistance; green silicon carbide is hard and easy to wear when polishing stainless steel; inferior recycled abrasive particles are easy to fall off, and the service life is directly halved.
Bond strength
The resin bond has poor adhesion and the ratio is reduced, resulting in a large amount of sand loss during polishing; high-quality resin is firmly bonded, the abrasive is not easy to fall off, and the use time is extended.
Thickness, density and particle size
Thin cutting blades and low-density impellers wear faster; coarse-grained ones are suitable for rough grinding and consume quickly, while fine-grained polishing losses are gentler.
2. Adapting equipment parameters
Speed matching
If the equipment speed exceeds the rated maximum speed of the cutting and polishing wheel, centrifugal force will continue to destroy the bond, and the abrasive will fall off quickly or even collapse. If the speed is low, the cutting resistance will increase, and local overheating will accelerate loss.
Equipment vibration and concentricity
The spindle is deformed, the fixture is eccentric, the machine ages and vibrates greatly, the cutting and polishing wheel is unevenly stressed, and one side wears rapidly, greatly shortening the service life.
3. Operation and usage habits (biggest impact)
pressure
Heavy pressure and sharp pressure for grinding/cutting will cause local high temperatures, burn out the resin bonding layer, and cause the abrasive grains to fall off in pieces; light pressure and uniform feed can significantly extend the service life.
grinding angle
Inclined single-sided grinding, long-term single-point grinding, localized concentrated stress, rapid thinning of one side of the grinding wheel and scrapping; maintaining vertical and uniform fit to the workpiece for more balanced loss.
Duration of continuous operation
There is no heat dissipation during long-term continuous processing, and the high temperature softens the binder and intensifies sand loss; intermittent processing and natural cooling can delay the loss.
4. Processing workpiece material
High-hardness workpieces: stainless steel, quenched steel, hard castings, the abrasive cutting load is large, and the wear rate is much faster than ordinary carbon steel.
Workpieces with impurities: Workpieces with welding slag, rust, casting burrs, and hard oxide scale will scratch the grinding wheel violently and accelerate wear.
Thin and soft profiles: ordinary pipes and mild steel, with low cutting resistance and longer service life of the cutting and polishing wheel.
5. Storage and early loss
The environment is damp: If the resin cutting and polishing wheel encounters water or moisture, the bonding agent will fail and sand will easily fall off the machine.
Bumping and squeezing: Invisible cracks may occur when stored, stacked, or dropped, and parts may break rapidly during use.
Storage aging: The resin sheet has a shelf life. If stored for more than 1 year, the bonding performance will decline and the durability will decrease.
