OCD
Heavy Duty
CNC Series
1500 / 2200 mm
3000 / 4000 mm
Distance between centers
Ø450 mm
Swivel over table
Ø420 mm
Max. external grinding dia.
INTRODUCTION
The external wheel is able to do formed O.D. grinding at once, in order to manage the total verticality and better the grinding efficiency.
APPLICATION:
Oversized gear shaft / Oversized printing shaft / Rolling shaft
Oversized motor shaft / Rubber rolling shaft / Oversized roller etc.
FEATURES
High Rigidity
Re-emforced structure, low gravity and high rigidity machine base, made of Meehanite cast iron through annealing and aging teatment, incorporated into a no-deformation and precise machine body.
Longitudinal and traverse sliding tables, with enlarged overall stride and rail way width, precision scrapping made on both horizontal and vertical sides, coupling with hydrostatic structure, light and steady movement of sliding table, repeated precision reaching up to µ level.
Increasing overall loading capacity of workhead
Workhead is driven by servo motor, providing step-less variable speed change. Supported by precision bevel bearing, attains vibration free transmission ability.
Direct drive hydraulic tailstock with micro adjustment
Tailstock equipped with hydraulic and stopper for easy operation, horizontal air bearing designed for easy displacement, reducing friction and increasing longevity.
