Usach 150-T4

The USACH 150-T4 is a CNC multi spindle ID/OD grinding machine representing the latest technology in machine design and is a substantial technical leap forward in ID/OD grinding. This machine has the following technical features:

  • Machine bed designed for improved thermal stability
  • Stationary workhead and dresser = accuracy and rigidity
  • Oversized monorail guideway system
  • Digital AC servo motors and drives
  • High axes speed with highest accuracy
  • High precision Heidenhain linear scales with air purge system

Part Range

With its large 16” cross axis, the Usach 150-T4 is ideally suited to cover a wide range of parts. The loading and unloading of longer parts and the length adjustment of the workhead can easily be accommodated through the generous opening provided by the two front sliding doors.

  • 17 inch swing diameter
  • Clamping weight 1000 lbs
  • U to 17 inch part grind length
  • ID/OD in same set up

This machine has a heavily ribbed base to ensure the highest sturdiness and precision work over time and is completely enclosed with two sliding front doors and one removable side door and back door. The workhead is completely enclosed with high precision class 9 bearings. Mounting weight is 200lbs (90 kgs) maximum with programmable workhead speed up to 1,000 rpm.
The longitudinal slide (“Z” axis) is a monorail style linear guideway system with rollers, driven by Fanuc AC servo motor and ballscrew. Closed loop with pressurized linear scale feedback.

Maximum speed: 66 ft / minute (20 m / minute)
Maximum stroke: 19.70″ (500 mm)
Resolution: .000004″ (.0001 mm)

The cross slide (“X” axis) is a monorail style linear guideway system with rollers, accommodating the turret. Slide driven by Fanuc AC servo motor and ballscrew for part infeed, infeed of the grinding wheel dressing and for the automatic compensation of the wheel wear. Closed loop with pressurized linear scale feedback.

Maximum speed: 66 ft / minute (20 m / minute)
Maximum stroke: 15.75″ (400 mm)
Resolution: .000004″ (.0001 mm)
