Thermo-Friendly Concept – You don’t have to worry about temperature differences
Automatic thermal deformation compensation system that allows dimensional stability regardless of ambient temperature variations due to both the coolant and other external factors. Improves the precision and quality of surfaces processed by both turning and milling. The machine does not require a pre-heating program at the beginning of the work program.
For superb accuracies in “normal” manufacturing environments
The machining accuracy of the workpiece changes significantly due to the ambient temperatures around the machine, the heat generated by the machine and the heat generated by the machining. The Thermo-Friendly concept is the unique concept of “accepting” these temperature changes, so that high accuracy can be obtained in normal factory environments, without special measures by operators.
Simplified machine construction
Machine design that equalizes ambient temperature
“Manageable deformation”—structural designing for controlled machine expansion/contraction (predictable directions), with heat transmitted evenly.
Thermally symmetric structure
The key to manageable deformation control
Box-build structure
Simple two-column box structure to ensure minimal thermal deformation.
Thermally balanced structure
The location of the front cover and the rear control cabinet allows uniform heat transfer.
Thermal deformation compensation for Machining Center / MB-46VA
Thermal deformation compensation for Lathe / LB3000EXII
Box slant bed
Okuma’s unique box slant beds manage thermal deformation. Thermal deformation is suppressed by eliminating heat sources from machine structures
Thermo Active Stabilizer – TAS-S
Thermal deformation of the spindle changes greatly both when the spindle is turning and when it is stopped, affecting machining accuracy.
TAS-S considers not only spindle temperature information but also spindle rotation, spindle speed changes, and spindle stoppage. Thermal deformation of the spindle is accurately controlled even when spindle speed changes frequently.
Thermo Active Stabilizer – TAS-C
When machining under changing ambient temperatures, machining dimensional changes are affected by expanding/contracting machine components as well as workpiece position with respect to the table in machining centers and workpiece size in lathes.
TAS-C, based on machine thermal characteristics, with appropriately placed temperature sensors and feed axis position data, will predict and accurately control thermal deformation in machine construction when ambient temperatures change.
Benefits
Fewer tool compensation checks
“Superb dimensional stability” means fewer compensation checks are required after the initial morning setup, regardless of shop temperature changes or afternoon/evening stoppages.
Dimensional accuracy improved with high-volume machining
By combining thermal deformation control with machining position, workpiece dimensional accuracy is improved even when a large number of workpieces are loaded.
