New development of the "T-11JAG-3S" internal
grinding machine for fully automatic combined machining
-Two new products to be exhibited at
the 23rd Japan International Machine Tool Fair -
Toyo Advanced Technologies Co., Ltd. (Head Office: Minami-ku, Hiroshima; President: Kenichi Yamamoto) will be exhibiting a total of three models at the 23rd Japan International Machine Tool Fair to be held at Tokyo Big Sight from November 1st to November 8th. These are two new products, the "T-11JAG-3S" internal grinding machine and the "T-182PG" vertical profile grinding machine, and the "T-182S" centerless vertical internal grinding machine which will be displayed for the first time at an exhibition in Japan.
The newly developed "T-11JAG-3S" is based on the "T-11JA"-
a high performance, general-use internal grinding machine with broad
market appeal. The T-11JAG-3S is equipped with a gantry loader, work
inverter, and a turret (divider) which was developed independently
by Toyo and can be equipped with four high-frequency wheelheads.
(The exhibited machine has specifications with three wheelheads.)
This machine is a combined machining unit which grinds multiple faces
(such as internal faces and both end faces) with high-precision,
using special purpose grinding wheels. It can operate in fully automatic,
unmanned, continuous mode.
The other new product, the "T-182PG" was
developed as a profile grinder for machining non-round parts such
as cams. The unit is equipped with special-purpose wheelheads for
rough grinding and finish grinding, and has greatly improved machining
efficiency compared to conventional profile grinders. High-precision
grinding with a profile precision of ±5μm is achieved using
a built-in servomotor for the work spindle and CNC employs the highly
functional, interactive "TOYOMATIC-4000" which
has an established reputation in internal grinding machines.
For
both models, we expect to begin taking orders in earnest after the
Japan International Machine Tool Fair in November.

At this Japan International Machine Tool Fair, Toyo's theme will
be "Open the Grinding Future." In addition to the exhibited
machines, our exhibit will introduce the overall concept of our vertical
internal grinding machine series -- as one example of a future product
line which pursues the possibilities of internal grinding machines.
Toyo's vertical internal grinding machine series, which first went
on sale last year, already ranges from the compact chuck type "T-181C" to
the mid-size centerless type "T-182S" and the large-size
chuck type "T-183C". At the Fair, we also plan to disclose
information on a large-size centerless type internal grinding machine
which is expected to go on sale next spring, and three ultra-large
vertical internal grinding machines which are currently under development
(max. work outer diameter 2.5 m).

[Overview of exhibited machines]
< New product > "T-11JAG-3S" internal grinding machine
The "T-11JAG-3S" is based on the "T-11JA" - a high
performance, general-use model with broad market appeal - and is
a fully automatic, combined grinding machine, which finishes multiple
faces with high precision.
A gantry loader and work inverter are provided as standard
equipment to enable one machine to handle work requiring machining
from two directions, such as both ends. This enables an automatic
cycle where the work is inverted, front to back, and achieves fully automatic,
unmanned continuous operation. This greatly improves productivity.
Toyo has independently developed a special purpose turret which enables
mounting of multiple wheelheads. The "T-11JAG-3S" has three
high-frequency wheelheads mounted on a turret divided into 90 sections.
(A maximum of four wheelheads can be mounted on the turret.) High-precision
is achieved by machining each of the multiples faces (internal
faces, taper faces, end faces etc.) with the optimal combination
of wheelhead and grinding wheel. An NC work spindle swivel mechanism
is available as an option, and this enables taper grinding with
even higher precision.
<New
product> "T-182PG" vertical profile grinding machine
The "T-182PG" is a vertical profile grinding machine
for high-precision, high-efficiency grinding of non-round parts,
and is equipped with two high-output, high-rigidity wheelheads.
The "T-182PG" is equipped with a high-output, high-rigidity
wheelhead for rough grinding, and a high-speed, high-rigidity
wheelhead for finish grinding. The different special-purpose
grinding wheels are combined to achieve high-efficiency machining
in rough grinding, and high-precision machining in finish grinding.
Response has been enhanced by using a built-in servomotor for the
C-axis (which is the work spindle), and profile precision has been
increased by employing direct control of the C-axis, and high-level
synchronous control with the X-axis which is both the cross-slide
axis and forming axis. Precision stability has been improved by
equipping the X-axis with a linear scale, and employing features
such as a column cooling system and a dual-head structure. With
these features, the system achieves high-precision machining with
a profile precision of ±5μm.
"TOYOMATIC-4000" - the established choice
for CNC internal grinding machines - is used here for
the first time in a vertical profile grinding machine.
A new function for simulating X-axis movement has been
newly added, and the system can even handle external
grinding of non-round shapes.

<New
product> "T-182S" vertical centerless internal grinding machine
The "T-182S", whose beautiful design and vertical centerless functionality won acclaim at the Chicago Show held in September of this year, will also be exhibited at the Japan International Machine Tool Fair.
The "T-182S" is Japan's first vertical centerless internal grinding machine, and is a machine suitable for machining of mid-size bearings with outer diameters up to 240 mm. Machine width is less than half that of conventional horizontal internal grinding machines, so production lines can be shortened.
