Aggressive Grinding's ID Cell consists of 3 CNC Overbeck, 5 manual/conventional grinders and 1 CNC Tru-Tech I.D. grinder. Our ID department has the capacity to grind diameters from 1/16" (.062) to 15" (15.000) in diameter with an accuracy of .0002. Other capabilities include grinding angles, compound angles, counterbores, and radius all with a low RMS finish. Oil is used in this equipment instead of coolant to provide a superior product. Greater accuracy is achieved with our honing equipment.
O.D. & Threading Department
Aggressive Grinding has extensive OD and Thread grinding capabilities to service your needs from basic performs to intricate forms. Our 29 CNC O.D. grinders include:
4 Rollomatics
4 CNC Okumas
2 Ex-Cello Thread Grinders
7 Kellenbergers
13 OD Tru-Techs
3 3-Axis Tru-Techs
We have 13 CNC Tru-Tech precision O.D. grinders that allow us to grind any profile faster and more accurately than an average conventional machine. We are able to generate multiple OD’s, angles, and radius in one set-up that would take several operations on a manual machine.
The three Tru-Tech 3-Axis CNC Precision grinders have multiple plunge, OD, ID and contour grinding capabilities. These machines allow for faster set-ups and hold tighter tolerances.
With 4 Rollomatic CNC Grinders we are able to manufacture endmills, punches, tapered tools, high performance drills, step tools, reamers and taps. The machines offer roughing and finish grinding in one operation on complex shapes and extreme diameter/length ratios.
In addition, our four Okuma CNC grinders support OD finishing in a high volume, automated production environment by completing multiple operations using the same machine.
Our seven Kellenberger Universal grinders have the capability of grinding multiple operations without unchucking the part; including OD, ID and face grinding. This is achieved due to the two OD and one ID wheels mounted within the machine.
An additional 6 Conventional O.D. grinders of the same manufacturer and matching tooling are used for larger diameters and roughing.
Our CNC Kellenbergers and two manual thread grinders give us the thread grinding capability to produce a variety of threaded solid carbide wear parts.
