Grind Tables


ABTech’s motorized wet grind tables are ideal for use in light grinding applications giving our customers the flexibility to turn their conventional surface grinding machine into a radial face grinder.

Heavy Duty Tables


ABTech’s heavy duty rotary table, model HDRT800/1070 being tested for radial accuracy with precision master test ball and ABTech’s MicroForm roundness gage software. Radial & axial accuracies less than 10 microinches on HDRT’s.

Reliable.
Maintenance Free.

Designed and manufactured in-house to extremely tight geometric tolerances, air bearings have no mechanical contacting parts to wear or create drag. This allows for decades of reliable maintenance-free motion.

We understand metrology needs often require operating in harsher environments. We use the most durable hardened 440C stainless-steel in our air bearings. This affords forgiveness from minor accidental touch downs that may result from low air pressure, excessive loading, or operator error

Accurate, Repeatable, Smooth Motion

Manufactured with tight geometric tolerances, our standard air bearings deliver radial and axial error motion of <2.0µ” (50.0 nanometers) and angular errors (coning) 1.0µ” (25.0 nanometers /25mm).

Superior Durability

Metrology is no longer relegated to QC labs. To maximize productivity, we know many applications require integrating measurement devices within the production and assembly processes. This means being exposed to harsher environments.

Benefits

Our “Pride in Precision” philosophy means providing you with the precise solution needed. We don’t believe selling our customers more, or less, than what their application calls for. Each air bearing is uniquely adapted to our customer.
