Brother’s CNC Tapping Centers are introduced.
|
A CNC Tapping Center is a numerically controlled machine tool used for machining
parts in every industrial field, featuring high speed, high accuracy, and high productivity.
Development of Tapping Centers has enabled milling and fine boring in addition to
tapping, achieving high productivity, improved machining capabilities, and greater
reliability that shatter conventional common sense.
|
Approach to development
|
Brother is a leading manufacturer of CNC Tapping Centers or #30 spindle machines.
We began creating machines from the viewpoint of on-site users.
We have systematically accumulated experience and machining expertise over forty
years so that we are able to put our advanced mechatronics technology into practical
use at the maximum level.Combining these hardware and software assets, Brother’s
CNC Tapping Centers have steadily been producing successful results all over the
world.
Brother always looks to the future to expand new possibilities and continue development.

Machines exported all over the world (as of March 2006)

Growth of CNC Tapping Centers
|
Since beginning production in 1985, we have achieved a considerable sales rate:
10,000 machines were sold in the ten years since the release.Sales then reached
20,000 after a further six years, and then reached 30,000 in only another four years.
We began to develop the innovative idea “Use #30 spindle machines for machining
possible by them” in 1998. “Creation of #30 culture” originated from Brother’s Tapping
Centers.
The accumulated production quantity reached 30,000 in 2005. The latest products,
such as motorcycles, automobiles, and IT equipment have been born from Brother’s
Tapping Centers playing an important role in production sites all over the world.

Advantages of #30 spindle machines
|
High-performance #30 spindle machines are fully capable of machining medium sized
parts although these were generally machined by larger machining centers.
They are also capable of drilling and milling, in addition to tapping.
Replacing conventional large machines with #30 spindle machines can reduce footprint,
power consumption, machining time, and emission of CO2.
* Machining conditions for example of advantages:
M6P1.0, depth of 12 mm, 40 holes, and spindle speed of 2,000 min-1

Features of CNC Tapping Centers
Equipped with originally developed NC
Brother’s Tapping Centers are equipped with an originally developed NC. Electro-mechanical
integrated development has achieved an ideal NC control that maximizes the features
of the machine.
High-speed and high-accuracy synchronous tapping
Equipped with our original “complete synchronous feed mechanism” (one pitch per
spindle rotation), high-speed and accurate tapping, from large to small diameter,
is possible and the required tap depth can be obtained.
M24 tapping has achieved peripheral velocity of 377 m per minute (world’s fastest).
A quick return function (10 times faster than when cutting) is also provided, leading
to reduction of tapping time and accuracy improvement.

of operation
High-speed spindle
An AC servomotor is used for the spindle to achieve dramatically quick response
and high accuracy. Startup time taken until the maximum speed is reached is reduced,
improving parts machining productivity.
High-speed ATC reduces tool change time
Brother’s original mechanism and NC technology have achieved high-speed ATC, reducing
non-cutting time considerably.
