G-Force Wheels

For Round Cutting Tools on CNC Equipment

Univel G-Force patented superabrasive wheels with grain-locking mechanism and a self-dressing wear-resistant bond yield a higher level of grinding performance.

Univel G-Force superabrasive wheels have been field proven to reduce total grinding cost up to 30% over the current high-performance wheels through reduced cycle times and wheel-dressing requirements. All Univel G-Force wheels are made to order and are custom engineered for specific applications, materials and machines.

Features & Benefits Specifications Photos Other

Superabrasive strongly held via patented bonding technology
Bond is optimized for wear resistance
Self-dressing characteristics maintain a consistently sharp grinding surface
Wheel profile can be regenerated in the machine by utilizing a MaxTORQ-BPR dressing system (see form #7880)
High metal-removal rates generating dramatically reduced cycle times especially on carbides and steels (Rc>40)
Extended wheel life through much lower reconditioning needs
Low power requirements and cool grinding eliminate burning and burrs in sensitive applications
Reduced residual stress after grinding
Consistent grinding performance throughout the life of the wheel
Longest life and form retention

High-performance Univel G-Force Wheels from Saint-Gobain Abrasives generate greater metal removal rates and dramatically reduce cycle times on carbide and steel round tools.

WORCESTER, Mass., July 11, 2006 -- Univel G-Force patented hybrid polyimide superabrasive grinding wheels yield a higher level of grinding productivity, consistent grinding performance throughout the life of the wheel and reduced residual stress after grinding, due to a grain-locking mechanism and a self-dressing wear-resistant bond.

Univel G-Force superabrasive wheels have been field-proven to reduce total grinding by 30 percent or more over the current generation of high-performance diamond wheels by reducing cycle times and wheel dressing requirements.

Univel G-Force wheels require less reconditioning than current generation superabrasive products and wheel profiles can be regenerated on the machine by using a 12,000 rpm MaxTORQ-BPR dressing system from the Wheel Dress division of Saint-Gobain Abrasives. The innovative bond structure of Univel G-Force wheels eliminates the need for stick dressing or dressing with a diamond roll after being profiled.

In a production application on 6mm Ø X 2-flute high-performance tungsten carbide drills, G-Force wheels were used to grind flutes @ .079-inch depth in one pass at 12 IPM on an 11 Hp grinder. Parts per wheel doubled, cycle time was cut by one-third and cost per part was reduced by 31 percent. In this application, no stick dressing was required and the wheel profile was regenerated on the machine with a MaxTORQ- BPR device. On a ¾-inch Ø X 4-flute, 1.5-inch flute length, 30-degree end mill, G-Force wheels ground flutes to .135-inch depth in one pass at 6 IPM and 3000 SFPM (15 MPS). Parts per wheel increased 2.5 times, cycle time was cut by 30 percent and cost per part was reduced by 32 percent.

All Univel G-Force wheel packs are made to order and are custom-engineered for specific applications, materials and machines.
