High accuracy!

Perpendicular type spindle head stock

concept

A wide range output spindle motor provides increased torque

at lower spindle speeds.

For machine slides, fast-response AC servo motors provide

quick acceleration and fast rapid traverse feed rates. The

absolute positioning pulse coder eliminates the necessity for

constant zero return procedures.

Massive Spindle Headstock for Con-tinuous Heavy Duty Cutting

In addition to unrestricted machining possibilities that are

performed easily, independent two-path control provides the

capabilities of two machines in one.

Simple, accurate work piece transfer is performed through

direct chucking: the right spindle slides coaxially to the fixed

left spindle assuring precise exchange of parts while both

spindles run simultaneously.

Due to the low center of gravity, the bed restrains vibration

which affects the machining accuracy, and improves the

rigidity of the machine.

Simultaneous Machining Can Be Per-formed with Ease

WT-300

Super high rigid slideSuper high rigid slide

2 way slide structure is adopted on the bed. The upper slide is horisontal, and the lower is 45 degree slant.

Because of well balanced structure, cross sectional surface area become larger, and stability, also become much better. Therefore super high

rigid structure base is achieved.

High rigidity

High productivity

Shorter idle time is achieved with faster rapid traverse rates of

16 m/min (630 ipm) for the X-axis and 27 m/min (1063 ipm)

for the Z-axis.

The Y-axis that has a stroke of +/-60 mm (+/-2.36"), allows

machining of accurate keyways, drilling off-center holes, face

milling, chamfering and circular threading(op.).

High Speed Z-Axis Rapid Traverse 27m/min (1575 ipm)

Up to 24 tools per turret are available, which permits process-

ing of the most complex parts.

The 24-station bi-directional turret features high speed

indexing. (0.2 sec to adjacent tool) It adopts servo motor

positioning and the shorter path selection function to ensure

precise indexing in the shortest time.

■ C/Y-axis milling ■ OD/edge face drilling

■ Outline ■ Pocketing

Turning Complex machiningSimultaneous machining of turning and milling is possible to XZC/

XYC axes. Also, complex drilling to edge face/OD, Outlining and

pocketting are possible.

■ Rough machining (OD/ID/edge face) ■ Pocketing

■ Copying lathe ■ Outline ■ Grooving ■ Threading

■ Cutting off ■ Drilling (fixed cycle) ■ bar feeding

Mult-tasking complex machiningSimultaneous turning/milling definition to Multi-turret, Multi-

spindle is possible.

The backside operation after the part transference to the sub-spindle,

simultaneous machining with the upper and lower turrets and wait-

ing are utilizable in the simulation function. The solid simulation

is available just after defining, so it is possible to check the machine

operation and make the best machining path.

With 2-D data for 2-spindle machine, the vertural tool is loaded.

Then, it does rough machining, finish machining, grooving, thread-

ing, and pocketing.

These functions here are to minimize unavailability of the machine. They are upgraded maintenance

facility to avoid damaging the machine.

without Excess load detection

Cutting insert and its sole plate will be broken, and the

turning tool holder is moved off by the shock of crash.

Cutting insert and its sole plate stay the same, and the

turning tool holder is a little bit slipped even if the tool is

hit by crash.

This feature minimizes the damage to machine in case of crash caused

by mistake in operation or programming. It works by detecting excessive

load immediately (within 8/1000 sec.) and tracking back. This function is

effective at all times for all slides (X, Z, Y, C and B-axis), differently from

load monitoring function which is effective only for selected tools.

Setting values necessary for carrying out the measuring cycle can be independently set for

both O.D. and I.D. measuring operations.

This allows for the optimum values in the required measuring cycle to be set.

No tool interference in compact tool holder design.

The new HAN-BEI-Mill is introduced for complex machining series.

It has measurement software for 3-dimensions: cross, straight, and angular milling.

Measured data is automatically input in the NC.

HAN-BEI In-process Measuring system

This is to facilitate tool setting more quickly and precisely. By touching the tool to one of

four sensors depending on its direction, tool offset amount is set into memory automati-

cally.

Work piece zero position can be set by touching one tool onto the face of a part.
