With PrecisionAccuracy

Parts machined with higher quality

The “Thermo-friendly” concept enables remarkable machining accuracy through original structural design and thermal deformation control technology. If frees you from troublesome dimensional compensation and warm-up. Exhibits excellent dimensional stability even during consecutive operation over long periods and environmental temperature change in the plant.

Eliminate waste with the Thermo-Friendly Concept

In addition to maintaining high dimensional accuracy when room temperature changes, Okuma’s Thermo-Friendly Concept provides high dimensional accuracy during machine startup and machining restart.To stabilize thermal deformation, warming-up time is shortened and the burden of dimensional correction during machining restart is reduced.

This controls the feedrate to provide machining suitable for corner shapes and circular shapes of machining parts, with the aim of ensuring high-accuracy machining and reducing cycle time.

This function is indispensable for die/mold machining. It is greatly effective in reducing cycle time and improving quality. Moreover, with the addition of AbsoScale (Optional), it can achieve further improvement.

� Hi-Cut Pro function (standard)

A worldwide first, Super-NURBS is a high-speed NC function with specially developed speed control functions for processingcurved surfaces. Super-NURBS gives you high-speed, high-accuracy and high-quality machining for any shape, ranging from machine parts to complex curves.

� Super-NURBS (Optional)

� Before � Super-NURBS

Shaping feedrates much faster

Much faster acceleration

Super-NURBS takes the machining program's command path and calculates a path that provides smoother tool movement and has less impact on the machine.

Machining along this smoother path means that acceleration and deceleration of the tool movement can be controlled, and greatly reduces the shock and oscillation on the machine and drive unit during high-speed feeding.

This improved speed control results in more efficient machining at the machine's maximum speed.

Communication

Getting the best from human operators and advanced machine tools

Human-machineinteraction

Satisfaction from complete control of a machine tool

� Setup operations

� Trial/continuous cuts� Programming � Tool preparations

As a “machine & control” builder, Okuma makes further strides in machine tool manufacturing with

this superb control featuring "Easy Operation." Okuma took a close look at the way machinists

actually operate machine tools, to help them create smoother and more effective ways of producing

parts. Novice operators as well as professional machinists get complete control—and satisfaction.

Moreover, what you want to see and do conveniently come together in a “single-mode operation.”

First, select one of three operation screens. Then simply touch the screen or press a function key to

see and do your job.

With spreadsheet simplicity —tool offsets, tilt, shape, life, etc—all the tool data required to cut a part can be registered here.Since the registered tool data is also used by Okuma auto programming (Advanced One-Touch IGF) and a collision check function (Collision Avoidance System), this screen will complete the entire registering process.

The touch sensor screen pops up from the tool registration screen. Tool compensation values are set while looking at a guidance message.

Okuma Control OSP-P300M

Easy tool registration

Interactive operations for machining centers

Machining processes can be newly added or revised on the Machining Order Table. Each process can be set freely with tool units, and know-how can be input with the edit function with a high degree of freedom. The recommended value is automatically set when new additions are made.

Can be operated directly from Machining Order Table.When a problem is detected it can be quickly corrected and checked, speeding up first part machining.

� Finding the best cutting conditions quicklySensors built in to the machine detect and analyze machining chatter. Machining Navi then navigates to the effective measures in a wide range of spindle speeds, from low to high.

Machining Navi M-i (Optional)

Cutting condition search for milling

� Adjust cutting conditions while monitoring the dataBased on the chatter noise captured by the microphone, Machining Navi displays a number of optimal spindle speed possibilities on the screen. The operator can change to the indicated spindle speed with a single touch and immediately confirm the result.
