Features：
● Genuine CNC piston lathe for camless oval turning.
● Economical horizontal slant bed type.
● Piston diameter range 50-200 mm.
● 2.2 mm ovality amount.
● Double screen.
● Both X and Z axes adopt precision linear guides from HIWIN/PMI.
● Both X and Z axes adopt precision ball screws from HIWIN/PMI with precision NSK ball screw bearings.
● 5.5/7.5 kW high-power and high-torque main motor.
● The precision of All our lathes is measured and compensated by RENISHAW laser interferometer, to make sure both positioning precision and repositioning precision are excellent.
● Fanuc 0i-TF CNC system + piston curved surface control software.
