YAMA SEIKI

Powerful Live Tooling Turrets ( For M Modle )

Eliminates manpower and cycle time

Live tooling and C-axis control capabilities on the GS-200 series allows the machine to perform multiple tasks on a work piece, such as turning, milling, drilling and tapping. This eliminates manpower and cycle time, while reducing accuracy lost, which will occur if the part is moved from machine to machine.

The 12-station YAMA SEIKI live tooling turret offers 12 stations available for live tooling ( live tooling tools rotate in working position only ) and features a non-lifting turret disk.

Utilizes advance servo indexing technology

YAMA SEIKI’s live tooling turret utilizes advance servo indexing technology to achieve 0.2 second indexing times for adjacent stations and 0.5 second for stations at the opposite end of the disk.

With the latest technology, live tooling is driven by an AC servo motor to provide ample power, in the form of torque. Now, even the toughest of jobs may be tackled without a sweat.

Ultimate C-axis Spindle

The most rigid and powerful type of C-axis

The Cf-axis and disk brake system available on the GS-200 series provides the most rigid and powerful type of C-axis on the market today. In Cf-axis mode, a servo motor is engaged and drives the rotation of the spindle; engagement time is approximately 1 second.

Working with the live tooling turret, the Cf-axis and disk brake system enables the machine to perform multiple tasks, such as drilling, tapping, and milling operations, including cylindrical and polar coordinate interpolations ( resembling a 4th-axis rotary table on a machining center ).

With the FANUC servo motor generating an ultra high resolution of 120 million pulses per spindle rotation and 240 Nm ( 176 ft-lb ) of torque ( cont. ), machined surface finishes are much superior than Cs-axis (driven by spindle motor) equipped machines. Plus, dynamic accuracy is within ±0.02° even under heavy cutting loads.

Y-axis Machining Capability ( For Y Modle )

Y-axis control further enhances multi-tasking live tooling capabilities and improves various machining precision. High precision grooving and X-axis off-center drilling are enabled.
With an abundant amount of Y-axis travel, 120 mm= + 65 mm / -55 mm ( 4.72” = + 2.56” / - 2.16" ), a wide variety of parts may be efficiently machined.

On Y-axis equipped machines, the turret is mounted on a secondary 30 degrees wedge saddle on top of the X-axis slide. Both X & Y axes have extra wide hardened and ground box ways, which are directly formed onto the saddles during the casting process. They are precision machined and widely spaced for maximum strength.

Grooving with Y-axis control produces grooves with higher accuracy.

Back-end Machining Capability ( For S Modle )

A 6” chuck size sub-spindle driven by a powerful 11 kW (15 HP, Peak) built-in type FANUC motor (Integrated Motor) for back-end machining is available on the GS-200 series.
The sub-spindle travels on the B-axis, which has extra wide hardened and ground box ways. The box ways are directly formed onto the machine bed during the casting process. They are precision machined and widely spaced for maximum strength.
Automatic part transfer of work piece from main spindle to sub-spindle saves manpower and cycle time, while reducing accuracy lost, which will occur if manually handling the part from machine to machine.
With Ø 38 mm ( 1.50" ) bar capacity, the sub-spindle configuration is also ideal for machining long work pieces such as small diameter shafts. Both ends of the work piece can be supported by the main and sub spindles, allowing the middle section(s) to be accurately machined.
