Super Finishing Services
Tri-Gon Precision offers a variety of super finishing and microfinishing services for machined parts. Our state of the art equipment produces finishes of 1 (mirror finish) to 32 microinches. This can be accomplished using various techniques. Microfinishing processes allow us to create the ideal surface finish for your machined part. In addition, close tolerance surface finishing can remove defects, improve geometry and efficiency, as well as reduce friction and noise. It can be done with any machining and grinding process. With the addition of honing, tumbling and lapping, achieving the desired surface finish for your machined part is possible with Tri-Gon.
The honing process offers low capital equipment cost, high metal removal rates and extreme accuracy. It can also be used on a variety of materials. Honing is an abrasive machining process that improves ID finish using mandrel and lubricants with specific properties to finish to precise dimensions. Finishing cylinders is a very common application for the honing process.
Mixing parts with specific media for tumbling and vibrating to accomplish desired microfinish. Could be tumbled with ceramic balls or cones, rough/hard granular material or softer media. Tumble finishing is ideal for smoothing and polishing a rough surface on small parts. Also known as vibratory deburring, this process is used to clean, deburr, descale, burnish, polish, brighten or prepare parts for further finishing.
Used on the surface of parts to improve the finish. Using Arizona stone, diamond stone and others, lapping can be used to create a particular surface roughness. In addition, this process can create very accurate surfaces, usually flat. Lapping works by rubbing two surfaces together with an abrasive between them until the desired finish is achieved.
Super finishing services allow for EXTREME finishing of parts to exact RMS callout. When you talk mirrors and microinches, the finishes are 1 RMS.
