General
The Okuma GA-36FII CNC O.D. Grinding Machine can perform the following grinding applications.
• Center work and optional chuck work operations.
• Straight plunge, multi-plunge, cylindrical traverse, face plunge and tapered traverse grinding operations.
• Taper, arc and complicated form grinding.
The GA-36FII is controlled by the Okuma OSP control and is capable of simultaneous two-axis control. This model is extremely flexible in handling a wide variety of workpiece shapes in a simple data setting. Addition of automation accessories will make sure that the Okuma GA-36FII CNC O.D. Grinder is an excellent part of the most up to date Flexible Manufacturing System.
Accuracy Assurance
• The bed is designed to be thermally symmetric. In addition, coolant is directly disposed of from the grinding point to the rear of the machine using a duct to minimize thermal displacement of the machine.
• Decreased friction on the table and wheelhead guide ways ensures accurate infeed of sub microns. Furthermore, brushless AC servo motors developed on the basis of OKUMA's sophisticated CNC technology have a precision of 0.1 micron least command increment at a feedrate of 16 m/min. (52.5 ft/min.). Incorporation of this high technology results in high accuracy profile dressing and profile grinding.
• Wheelhead, table feed and the endwise face locator positioning is performed by entering the corresponding program data.
Wheel Spindle
The wheel spindle is rigidly supported by an Okuma hydrodynamic bearing (also called a non-concentric sliding bearing) on both the wheel side and wheel pulley side of the spindle. Wedge-shaped oil films give rigid support for the spindle for true-center rotation with a minimum of axis displacement.
The high load carrying capacity with excellent vibration dampening characteristics of the Okuma wheel spindle permits faster and heavier stock removal and shorter spark out times.
Temperature rise of the wheel spindle is maintained at "room temperature + 6.5ºC" through a variety of improvements. Furthermore, it is designed to minimize the displacement of the spindle center due to thermal deformation.

Axis Servo Drives
• Both X and Z axes are driven by the ultra-precise ball screws and pre-loaded.
• Ball screw nuts, center mounted between the ways for optimum drive conditions.
• The 40mm (1.57 in.) X-axis ball screw is implemented along a Turcite flat and V way.
• The 45mm (1.77 in.) Z-axis ball screw is implemented along a Turcite flat and V way.
