Okuma’s new GA26W high speed, compact grinder is now equipped with the intelligent OSP-P300G CNC. Okuma’s open architecture OSP-P control runs on a Windows-based platform and fully integrates the machine, motors, drives and encoders, allowing for enhanced machine performance and true customization to suit particular machining needs. The Easy Operation control and touch screen increase efficiency by letting users easily and quickly toggle between machine operations, programming and wheel preparation screens.
The innovative wheelhead traverse structure gives this CNC grinder a solid, compact footprint that saves valuable floor space while the user-friendly design allows various workpieces to be loaded effortlessly for easy automation in high production environments. The extremely rigid foundation paired with Okuma’s hydrodynamic wheel spindle allows for heavy-duty grinding.
The GA26W is equipped with standard chatter control function that automatically adjusts wheel speed for accurate, stable machining. The powerful 7.5kW (15kW-optional) grinding wheel spindle is ideal for grinding mass produced parts with precision.
Key features and benefits of the GA26W:
- OSP-P300G control
- IGAP+ conversational programming
- Large 610mm (24”) grinding wheel
- Tailstock quill stroke 50 mm
- Wheel spindle motor: 7.5 kW (10 hp) [15 kW(20hp) option]
- High feed rates X-axis ø30 m/min; Z-axis: 20 m/min
- Enhanced rigidity for powerful grinding
Related Glossary Terms
Condition of vibration involving the machine, workpiece and cutting tool. Once this condition arises, it is often self-sustaining until the problem is corrected. Chatter can be identified when lines or grooves appear at regular intervals in the workpiece. These lines or grooves are caused by the teeth of the cutter as they vibrate in and out of the workpiece and their spacing depends on the frequency of vibration.
- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
- conversational programming
Method for using plain English to produce G-code file without knowing G-code in order to program CNC machines.
Rate of change of position of the tool as a whole, relative to the workpiece while cutting.
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
- grinding wheel
Wheel formed from abrasive material mixed in a suitable matrix. Takes a variety of shapes but falls into two basic categories: one that cuts on its periphery, as in reciprocating grinding, and one that cuts on its side or face, as in tool and cutter grinding.
