A closed-loop control system for the X, Y, Z and B axes with standard 1μm linear scales and rotary scale provides
Use of an oil jacket and constant lubrication air mist volume for stabilized high accuracy cutting operations. Spindle bearings constant mist lubrication
Manual operations relating to machine movements are separate from the NC operation unit and centrally arranged on the pendant operation box. Manual machining operations can be performed smoothly
High-Performance CNC controller
A newly developed spindle for optimum high speeds, assurance of high accuracy and heavy duty machining.
Use of an oil jacket and constant lubrication air mist volume for stabilized high accuracy cutting operations.
・Spindle bearings constant mist lubrication
In addition air-oil mist over-sized spindle bearing, the entire unit is nitrided, hardened and precision ground to assure accuracy over the life of the machine.
Extra wide guideways that withstand the cutting force moment for assuring powerful machining with virtually no thermal displacement.
Spindle designed with extremely rigid, long-span type bearings and an automatic spindle end clamp for increased cutting force and positioning not found on other machining centers.
This new clamping mechanism greatly increases the cutting force. Additionally, the spindle can be NC positioned at any location over its entire extension.
BTD-110 standard type spindle thermal displacement after 7 hours of continuous no-load operation in a temperature controlled room at 1000 min-1.
X-axis direction : -1 μm (-0.04 μin)
Y-axis direction : -14μm (-0.55 μin)
Z-axis direction : 23μm (0.91 μin)
Composite machining of any shape such as cutoff and hale type finishing on an arc or along a straight line on any plane is possible with this C axis spindle control. Simpletype programs and tooling available for the machining of complex seal surfaces on the slots of such workpieces as vacuum devices.
A long spindle head nose allows easy access to the workpiece, assuring stabilized accuracy even during heavy-duty machining operations.
(The spindle extension is 500 mm (19.7 in) same as standard.)
Note : Detailed of option specifications to be decided at a separate meeting
All major components are made of topgrade casting in a design based on fundamental machine tool building concepts. These slideways are also hardened and ground.
Improved access of the machine to the workpiece by employing a nose type spindle head construction which also assures stability during heavy-duty cutting operations.
Rigidity is a must for the bed supporting the entire machine. Sturdy and 4-way guideway construction of the bed assures high accuracy, rigid support.
The saddle is structurally designed and built to assure maximum straightness and paral-lelism of crosswise and longitudinal move-ments of the table.
B-axis positioning time: 14 sec. (0°～90°indexing), 37 sec. (0°～360°indexing)
The revolutionary type of clamp is standard with a highly rigid double pinion-type drive system and rotary scale for stabilized precision table indexing.
After placing workpiece on a suitable location on the table surface, workpiece paralleling is simply completed by the automatic measuring and recording of workpiece position dimensions which is then used to precision index the table. Table will then be precision indexed to bring it in parallel with the X axis.
Cylindrical and end surfaces can be machined continuously by the B-axis continuous indexing function, eliminating the need for an optional independent-type NC rotary table. Cylindrical surface machining is easily programmed in the manual programming by the cylindrical interpolation function
TOSNUC999(Triple nine) permits quick switching between manual, MDI and Automatic operation modes.
1.Memorize a series of input operations beforehand in one of the special keys and press these keys to execute operations continuously.
2.Memorize a combination of NC standard displays such as main, sub and window displays in one of the special keys. By pressing these keys it displays the combination memorized.
TOSNUC 999 is standard equipped with USB port and CF card slot in response to capacity enlargement of NC programs.
During programmed operation (i.e., background operation), an NC tape image of another program can be checked graphically. After program check, relevant tool path is drawn.
TOSNUC 999 stores in its memory all data created by the operator as NC programs. Programming is very easy by combining these programs, using various teaching functions.
Very useful device for managing long programs.
Manual operations relating to machine movements are separated from the NC operation unit and centrally arranged on the pendant operation box. Thus, combined NC and manual machining operations can be performed smoothly.
