Pride Air Bearing Grinders For Ultimate Accuracy

Experience the ultra precision of the Pride grinder’s air bearing grinding and positioning accuracy – achieving 15 millionths (.38µm) TIR with a micro finish.

Pride Engineering air bearing die grinders are your best chance to hold the tightest tolerances and high quality finishes for peak tooling performance. The air bearing work head and wheel head spindles solidly mounted together on a floating granite surface plate will always provide the truest roundness and finest surface finish possible.

Closer Tolerances. Better Surface Finish.
Simply put, no mechanical bearing can ever achieve the roundness or surface finish that is possible with the Pride Air Bearing Grinder. Pride Grinders grind any ceramic, carbide or hardened tool steel die with internal or external diameters, tapers, and radii within .000015" (.38µm) TIR while holding a surface finish of A or better without any polishing.

• Linear Slides for X, Y and Z axis are fitted with absolute scales providing closed-loop feedback resulting in a .00001” (.25µm) diameter accuracy.
• Granite Surface Plate Mounting
• Solid rigidity provides precision and prevents chatter that degrades the surface finish. The Model 30 achieves unbeatable rigidity by mounting the rotary and both spindles on a single 4 in. (100 mm) thick granite surface plate.
• Air Suspended Mount
• The granite surface plate that holds the rotary and the two air spindles is suspended on air to isolate the work from high and low frequency vibrations of any origin.
• Digital linear actuator utilizes a planetary roller screw for the spindle in-feed.
• Direct drive rotary operates with smoothness for increased accuracy and less maintenance

Direct Drive Rotary

• The frameless torque motor is smooth and accurate to .00008" (2µm) roundness. No gears, no joints and no chains increase speed and require less maintenance.
• Rotary axis rotation of -10° to +95° will repeat to ±2.5 arc seconds.
• No Chatter -
