is a leading manufacturer of Resin Bond Diamond and CBN Blades that are vital to a wide variety of industries including precision machining, tool & die, ceramics, electronics and photonics.
The 1A8 Thinwheel is used for high precision slot grinding, slicing and dicing, and some fine cut-off operations. The blade is available in Diamond or CBN and is used in single, as well as gang wheel applications, on standard surface grinders, creep feed grinders, OD grinders, machining centers, and specialized dicing machines. Thinwheels are available in standard diameters of 3", 4", 5", 6", 7", 8" and 10" with thickness ranging from .004" to .250", in increments of .001" or fraction thereof, and holding a thickness tolerance of +/-.0001. The 1A8 Thinwheel is designed to be used in conjunction with specific Diacut type 1A8 Flanges. The flanges are available in varying diameters, which allows for the appropriate amount of wheel exposure (maximum wheel exposure should not exceed 15 x the thickness of the wheel) and for down flanging as the wheel wears. The standard hole size on the 1A8 Flange is 1 1/4", but special hole sizes are available upon request.
1A1R (Cutoff) Wheel
Diacut's standard Cut-off Wheel. This wheel is used on cut-off machines, surface grinders, OD grinders, and machining centers. The Cut-off Wheel is available in diameters of 3", 4", 5", 6", 7", 8", 10" and 12" and in various thicknesses. A steel core, with a tapered diamond or CBN section which assures free cutting, is used on all Diacut Cut-off Wheels. The use of a Diacut 1A1 Type flange is recommended for rigidity and longer wheel life. This flange is available from 3" to 8" in diameter, in increments of 1/2". The standard hole size for the 1A1 Type flange is 1 1/4". However, if a smaller hole is size is required, the Diacut Type 1A1 Hole Reduction Flange is available.
1A1R Special Wheel
The 1A1R Special combines a steel core with the 1/4" diamond or CBN section. The result is a highly rigid wheel primarily used for deeper cutting applications, which require additional wheel exposure. This wheel is used on standard surface grinders, OD grinders and machining centers. The 1A1R Special is available in 4", 5", 6", 7" and 8" diameters. The thickness ranges from .032" to .375" in increments of .001". The use of a Diacut 1A1 Type flange is recommended for rigidity and longer wheel life. This flange is available from 3" to 7" in diameter, in increments of 1/2". The standard hole size on the 1A1 Type Flange is 1 1/4". However, if a smaller hole is required, the Diacut 1A1 hole reduction flange is available.
1A1 Precision Wheel
The 1A1 Precision Wheel is primarily used for precision slot grinding in thickness over .050", where a thickness tolerance of +0/-.0005" is sufficient. The 1A1 Precision wheel is available in diameters of 4", 5", and 6", with a 1/4" diamond or CBN depth and an abrasive core. The Diamond or CBN section is flush with the abrasive core, or upon request, is available with a 1/4" wide, approximately .005" deep relief. The thickness of the 1A1 Precision Wheel ranges from .020" to .250", in increments of .001" or fraction thereof. The use of a Diacut 1A1 Type support flange is required for stability and safety. The 1A1 flange is available from 3" to 5 1/2" diameters, in increments of 1/2". If a smaller hole size is required, the Diacut 1A1 Hole Reduction Flange is available.
Thinwheel and Reusable Mandrel
Diacut ThinwheelsTM used in conjunction with a mandrel are used to grind OD and ID slots on surface grinding machines using a collet adapter, ID grinders, jig grinders, and high speed grinding attachments on lathes and milling machines. The standard shank diameter for the mandrels are 6mm (50mm long), 10mm (75mm long), 1/4" (2" long) or 3/8" (3" long). They have a mounted back flange and a removable front flange, which are available in various diameters to allow for the appropriate amount of wheel exposure. The mandrel allows you to hold Diacut's Thinwheel, manufactured in solid diamond or CBN, in thickness from .004" to .250" in increments of .001" or fraction thereof. The Thinwheel is available in diameters of 1", 1 1/4", 1 1/2", and 2".

Satellite WheelTM System
GRINDING THIN SLOTS WITH LARGER DIAMETER WHEELS
Until now, the dressing and sizing of conventional grinding wheels, as well as the grinding process, was very time consuming. The largest diameter available was 10" and all grinding wheels had a continuous, uninterrupted superabrasive section on the periphery. The result: The conventional wheel produces inexact slots.
Resolving the problems mentioned above was the motivation for developing the new SATELLITE WHEEL AND FLANGE SYSTEM. This new method of slot grinding was previously unavailable on the market, but offers considerable advantages compared to the conventional grinding process: Improvement of the general operation, cut quality and cost savings.
The Satellite Wheel concept allows for the grinding of various slot widths using the same flange. The ideal wheel diameter is 10" to 20". However, other sizes may be produced upon request. The new technology can be applied to all grinding machines for hard, brittle materials. Additionally, this technology distinguishes itself with a considerably improved cooling characteristic, as well as greater stability of slot shape and improved overall cut quality.
This new system allows the customer to grind thin slots, approximately 0.010" and wider, by placing three-inch diameter diamond or CBN wheels between the front and back flanges. The Satellite system is very economical, while still achieving the highest quality cuts from a wheel with a diameter of 10" or larger.
The back flange allows for the attachment of six to eight small "satellite" wheels, which are placed along the O.D. of the flange. The Diacut satellite wheels project approx. 0.250" the flange. However, the amount of exposure can be adjusted to accommodate specific applications. The center bore is adjusted to match the spindle on any grinding machine.
The front flange is responsible for holding the satellite wheels in place, while providing pressure and stability for the cut. Both flanges together are constructed to guarantee a concentric running of the wheel, both peripherally and axially.
Satellite Wheel Rotation Principle
As the diamond or CBN Section protruding from the flanges wears, the wheels can be rotated up to six times (depending on the cut depth) by separating the two flanges. This "rotation principle" saves costs and allows for high versatility.
