|commutator cutting machine r680c/e|
major technical parameters:
turning precision: axiality: ≦0.005mm, inter-piece jump: 0.002mm, surface roughness: ≦ra0.4.
o.d. of rotor: φ20～φ60mm.
length of rotor shaft: 220mm.
diameter of rotor shaft: φ7～φ14mm.
o.d. of commutator: φ18～φ40mm.
cutting length: 40mm
