Roller Shaft Industry
Roller shafts cover conveyor rollers, coating rollers, calender rollers, guide rollers, rubber roller cores and metallurgical rollers. They are mainly made of carbon steel, alloy steel and stainless steel. Some rollers are treated with chrome plating, thermal spraying or rubber cladding, widely used in paper making, film, lithium battery, textile, metallurgy and conveying equipment.
After forging, turning and welding, roller shafts have tool marks, roundness errors, weld beads and oxide scale. Surface irregularities will cause uneven film stretching, inconsistent coating thickness and scratches on web materials. Machining must ensure cylindricity and surface roughness to meet base requirements before chrome plating, spraying or rubber wrapping.
Lean Abrasives’s diamond grinding wheels are used for cylindrical grinding of roller surfaces and precision finishing of journals and positioning shoulders, stabilizing dimensional tolerance and roundness while avoiding grinding burn, suitable for finishing high-hardness alloy steel rollers.
Our high-precision sanding belts are suitable for outer circle grinding, weld blending and surface roughening of roller blanks. Coarse grit removes stock and weld beads rapidly, and fine grit refines the surface step by step to form qualified anchor profile for plating and spraying. Flap wheels, sanding discs and abrasive discs handle deburring and trimming on end faces, shaft shoulders and keyways.
Polishing wheels are adopted for mirror and matte precision polishing to meet high-cleanliness requirements of coating rollers and film guide rollers. Non-woven polishing brushes and nylon roller brushes gently clean roller surfaces and remove fine oxide and debris without scratching the substrate.
