Superfinishing is a machining process that increases part life, reduces wear, achieves tighter tolerances, strengthens load-bearing surfaces, improves sealing performance, and eliminates machine break-in periods. Originally developed by the automotive industry in the 1930s and still used there extensively, superfinishing is now employed in applications as varied as the production of small medical components like hip implants and the creation of aerospace turbine parts.
No heat; no thermal damage!
Utilizing a rotating workpiece finished with a moderately soft polishing stone, it is commonly employed on steel parts, but also works with more exotic materials like ceramics, plastics, or titanium. Since it doesn’t heat the workpiece, it can remove heat-damaged surfaces caused by prior grinding and lathe turning operations, thus enhancing component life; it’s one reason today’s auto engines last so much longer than those in the past.
Alternative Surface Grinding (ASG) offers superior superfinishing services integrated with our microfinishing capabilities that include double disc grinding, hyprolapping and light band microfinishing.
ASG is the tight tolerance king
We specialize in microfinishing small parts to extremely tight tolerances. Our double-disc grinding capabilities, offered on both horizontal and vertical spindle grinders, can hold tolerances as tight as 0.0006” and flatness within 0.0003.” We can handle volumes ranging from 250 to a million pieces or more. Likewise, our hyprolapping technology, which can grind two sides of a flat part simultaneously, is ideal for processing thin parts without deforming them. Hyprolapping can hold tolerances of 0.0002” and flatness within 0.00005”.
ASG has experience working with a broad array of sectors and industries, including aerospace, agricultural equipment, automotive, and transportation. In addition to precision grinding and finishing, our capabilities include de-burring, tumbling, heat-treating, shot-peening, surface coating and non-destructive testing.
