Machine configuration to achieve high efficiency grinding

High efficiency grinding

NC high-speed oscillation

To enhance grinding removal efficiency, and to achieve high efficiency grinding

This guideway with minimal following error and high rigidity enables high-speed oscillation.

Hi-G control (Standard)

● Oscillation frequency: up to 585 times/min

● Rapid traverse 30 m/min (Z-axis)

20 m/min (X-axis)

● 0.1 µm control

● Dn value: 1,600,000 (maximum)

● Oil air lubrication

Restraining 5-surface hydrostatic guideway system (Z-axis)

● High rigidity 300 N/µm● Maintenance free Non-contact● No backlash Minimal following error

The internal grinding spindle with high-speed,high rigidity enables powerful grinding.

During positioning, this function controls the acceleration/

deceleration speed in accordance with the speed-torque

characteristics of the BL motor, resulting in high-speeds and highly

stable positioning.

Accordingly, this Hi-G control function reduces positioning

time and greatly reduces non-cutting time.

Non-grinding time reduction

● Low-height design makes for more clearance from the ceiling of your factory

● On-machine type makes relocation easy

Non-grinding time reduced by high-speed loader

High-speed loader (Optional)

High-speed loader at a rapid traverse of 180 m/min

Abundant variety of Ioader patterns that facilitate automation

● A fixed headstock configuration enables to allow dressing during loading.

This function significantly reduces the cycle time.

Larger space for workpiece Ioading/unloading

● This machine configuration with a larger X-axis travel allows the wheel to retract farther when

loading/unloading the workpiece, resulting in greater safety.

OSP-U20G

Absolute position feedbackOkuma's absolute position feedback system saves your current position when power failures or inadvertent operator errors occur, making zero point recovery restarts unnecessary. That's why Okuma's OSP CNCs have been keeping customers happy for over 30 years.

Improved ease of use● Flat panel● Simplified setting of workpiece and diagram zero points

“Machine & Control” mechatronicsOSP was originally developed by Okuma. Okuma offers a truly integrated single source mechanical and electrical entity because Okuma totally controls the manufacture from design to inspection.

Reliable and variable software

Help function

Okuma has developed their systems with next-generation flash memory for the most reliable CNCs available. Use our NC controllers for cutting-edge functions and performance.

■Far less trouble-shooting downtimeAs soon as an alarm is indicated, the NC has the printer print out a hard copy of the information needed to trouble-shoot the problem. You can fax the copy right to the service center and spare yourself the usual long and involved phone calls.

■Provides “real-time” results informationThe CNC compiles actual production data as it happens and outputs it to the screen. ● Operators can use the data

make to improvements● Accurate up-to-date

information at your fingertips

● The end-user, armed with a PC, can manage things right on the spot in the way he or she wished.

■Reduced setup change timeBy streamlining the file operation order, input/output of part programs takes far less time. End-users can use a conventional PC to display their own operation procedure up on the NC screen.

Standard

An assistant for key operations

When you cannot find specified G code/M code etc. in machining programs, one touch on 'Help' key enables you to see the content of each code on NC display, efficiently assisting you in machining operations. When an alarm is activated, the 'Help' key will display the content of alarm on NC display, assisting the operator in troubleshooting.

Energy-saving functions● Saves energy with power-saving timer ● Display screen off, mist collector stopped, in-machine lighting off ● Energy-saving LED lighting in machine
