Cylindrical Grinder

OCD-45150 / 45220 / 45300 / 45400

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.


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.


Oversized gear shaft / Oversized printing shaft / Rolling shaft
Oversized motor shaft / Rubber rolling shaft / Oversized roller etc.


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.
