BTH-130.R24

Experience with over 8,000 machines with continual technical improvements, the “BTH-130.R24, H-Cube” has been developed to provide horizontal boring operational ability with machining center productivity and flexibility

Main features

Floor space saving

Efficient 7m by 7m (23ft by 23ft) “Square floor space”

Easy chip disposal

High-level side discharge hinge-type chip conveyor.

Protective covers

Operator protection from chip and coolant with easy access

Workability

Ease of operation with manual pendant box and environmental platform

Operation capability

Enhanced functions and options from TOSNUC 999

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

3-step (low, middle and high) spindle drive system provides wide speed range, high rigidity and high torque. Therefore, lots of demands in machining such as in facing, boring, drilling and tapping will be effectively performed with high accuracy and high productivity.

Minimal thermal displacement of spindle head

Use of an oil jacket and constant lubrication air mist volume for stabilized high accuracy cutting operations.
・Spindle bearings constant mist lubrication

Hardened and ground spindle

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.

Step-type column guideways

Extra wide guideways that withstand the cutting force moment for assuring powerful machining with virtually no thermal displacement.

Spindle construction designed for deep hole boring

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.

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.

Long nose type spindle head (option)

A long spindle head nose allows easy access to the workpiece, assuring stabilized accuracy even during heavy-duty machining operations.
(The spindle extension is 700 mm (27.3 in) same as standard.)

Note : Detailed of option specifications to be decided at a separate meeting.

Example of machining data, material : AISI 1055 (Carbon steel)

High speed precision machining is achieved through the use of a new B-axis drive mechanism (pat. pending).

B-axis positioning time : 15sec (0°～90°)
The revolutionary type of clamp is standard with a highly rigid double pinion-type drive system and rotary scale for stabilized precision table indexing.

Set-up compensation function (option) eliminates manual workpiece centering!

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.

Efficient NC rotary milling (option)

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 programing by the cylindrical interpolation function.

TOSNUC999 (Triple nine) permits quick switching between manual, MDI and Automatic operation modes.

Customizing keys

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.

Full screen program editing function helps create an NC program easily.

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.

Pendant operation box

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.
