Most ground parts are turned first. The CNC turning centre lets a workshop make shafts, pins, flanges and bushes on the same supplier's equipment before they go to the cylindrical or surface grinder.
The Prayosha CNC turning centre is built on a fabricated slant-bed structure. On a slant bed, chips fall away from the cutting zone and the operator can reach the chuck easily. The machine has a 2000 RPM, 10 HP spindle, a six-station turret for 25 × 25 mm tools, an 8-inch manual chuck, a manual tailstock and Mitsubishi CNC.

Finish the turned parts on the hydraulic cylindrical grinding machine.
Frequently asked questions
What is the maximum turning length?
300 mm.
Which CNC control is used?
Mitsubishi.
What is the positioning accuracy?
± 0.025 mm, as specified for this model.
Is lubrication automatic?
Yes. A centralised lubrication system supplies oil to the axes, and the spindle is grease lubricated.
