Thermo-Friendly Concept

“Working with temperature changes”

Okuma’s Thermo-Friendly Concept is a structurally designed, thermal deformation control technology that provides astonishing cutting accuracy. It frees the operator from troublesome machine warm-ups and offsets.
During long production runs with changing shop temperatures, the required part dimensions remain stable.

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.

TAS-C: Thermo Active Stabilizer- Construction (TAS-C)

“Proactively” keeps the machine [construction] in optimum, stable condition during shop environment temperature change- resulting in superb (stable) machining accuracies.

TAS-S: Thermo Active Stabilizer- Spindle (TAS-S)

Accurate compensation during spindle start/stops, and speed changes.

Cutting condition search function for turning

Machining Navi L-g (guided, harmonic spindle speed control )

Varying the spindle speed in accordance with the best amplitude and period makes it possible to suppress chatter during turning operations. Tool life can be extended and machining time reduced with use of the optimum cutting conditions, producing significant effects in drilling/boring bar, threading, and grooving applications.

Cutting condition search in threading

Machining Navi T-g

When chatter occurs in threading, general methods to resolve the problem have been to either lower cutting conditions at the expense of productivity, or to use special chatter-resistant tools at some cost. Machining Navi T-g (threading) provides optimum control, increasing or decreasing spindle speed on each pass to inhibit the periodic vibrations that are a cause of chatter.

Machining Navi M-g (Optional)

Push cutting conditions higher to increase profit
Machining Navi instantly determines the optimal cutting conditions for highly efficient machining.

Spindle speed and chatter are linked in a periodic manner, manifesting as alternating ranges with and without chatter.
This means that there will be cases in which chatter cannot be suppressed with a reduction in spindle speed, and other cases where increasing the spindle speed will eliminate the chatter.
Machining Navi navigates the extremely difficult process of finding the optimal spindle speed value by analyzing chatter and instantly determining (powerful computing) the best spindle speed.

Cutting conditions can be changed while looking at analysis results
Based 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.
