Fine Grinding Wheels / Superabrasive wheels
- Faster Material Removal Rates
- Finer Finishes
- Better Flatness Control
- More Consistent Process Control
- Very Competitive Pricing
Lapmaster International's full line of super-abrasive (CBN or Diamond) fine grinding wheels easily adapt to all brands of fine grinding machines and many types of conventional single and double side lapping systems. The fine grinding process produces flat lapping quality on a variety of materials without the expense and “mess” associated with lapping. Fine grinding using Lapmaster supplied fine grinding wheels produces material removal rates are up to 20 times faster than lapping. Our special vitrified and resin bonds combined with our use of the highest quality most closely graded super abrasive powders means consistent quality for all parts ground on Lapmaster supplied fine grinding wheels. Vitrified wheels are supplied with configurations comprised of round, square or hexagonal pellets applied to steel backup wheels.
Pellet type wheels are available with spaces (grooves) between the pellets or with the inter-pellet spaces filled to provide a smooth surface. Segmented wheels which appear as a solid grinding surface are also available. Grinding surface pattern, abrasive particle size, bond and thickness of grinding media are all customized for your specific application. Vitrified bonds are the longest lasting and easiest to control for flatness. Our resin bond wheels are provided with a solid segmented grinding surface. This surface can be either serrated or plain depending on the application. Resin wheels are suited for applications where minimal material removal and fine surface finish are required. A variety of wheel diameters are available to suit your single side or double side fine grinding needs. Lapmaster fine grinding technicians are available to determine wheel specifications best suited for your specific application(s).
Work holder Discs and Pads – Single Sided Machines
Work holder Discs are used to separate fragile workpieces during lapping and polishing operations to prevent damage. They are also used when work pieces do not lend themselves to batch loading. The discs are made of a laminated phenolic and are available from 1/32" to 1" thick and in diameters of 4-3/16" through 35-3/4". Pads are available in sponge rubber or felt material and are used to compensate for minimal height differential in the parts being lapped.
Dual Face Machine Work Carriers
Lapmaster offers work carriers for virtually any dual faced machine currently on the market. Stock materials include spring steel (strongest, most durable; for thin, precision components), steel with molded plastic inserts (for use in lapping and polishing silicon wafers and other sensitive electronic materials), G-10 (fiberglass reinforced, non corroding and non-water absorbing - ideal for thicker parts), PVC (for use with relatively thick parts), lexan (for scratch-free fine polishing applications), vinyl (most economical for short runs), and phenolic (resin-laminated cloth, for use with oil-based slurries). Workholes can be custom cut to suit any part geometry.
