BTD-110H.R13/R16

A newly developed spindle for optimum high speeds, assurance of high accuracy and heavy duty machining.

Spindle-torque diagram

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)

Spindle normal direction control ((spring necked turning)) (option)

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.

Spindle head

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

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.

Supporting both USB flash drive and compact flash (CF)

TOSNUC 999 is standard equipped with USB port and CF card slot in response to capacity enlargement of NC programs.

• Multi-window triple display
  The display of TOSNUC 999 can be divided into three separate screens where simultaneous display of two different programs and offset data necessary for machining is possible. Also, data entry and editing can be done separately on each screen.
• Multi-editing function
  A new program can be easily created by referring to and utilizing a previously made program on the multi-window display.

Visual program check function (option)

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.

Triple teaching function for simultaneous machining and NC programming (option)

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.

• Manual teaching function
  All machining data such as tool path, spindle speed and feedrate as obtained in the manual mode are stored automatically as an NC program.
• MDI teaching function
  When machining processes are executed one by one consecutively in the MDI mode, all such data are stored automatically as an NC program.
• Auto teaching function
  In the AUTO or DNC mode, any data which has been modified can be fed back to the memory automatically.

Various functions shown above significantly improve operability

• Manual alignment (centering) function
  The touch sensor or master tool comes into contact with the measured surface of a workpiece according to the interactive screen, inner and outer diameters and angle of inclination of the specific workpiece that automatically calculates set-up.

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.
