Maximum Performance Turning Center

With Leading technologies and the highest quality components, the GS-6000 series ultra high performance turning center combined super high power output, high rigidity construction, large diameter servo driven turret and YAMA SEIKI 35 years experiences. It provides big working range and super heavy cutting capability. Additional, live tooling turret and C-axis are available to allow GS-6000 series can turning, milling, drilling and tapping. Thus, done in once can be achieved. Furthermore, the excellent machine performance and durable components can meet today and tomorrow's most demanding turning application.

The first thing you’ll notice inside the door of the GS-6000 series is the massive turret, which boasts a turret disk over 28 inches in diameter. Blazing fast indexing times of 0.5 seconds from station to station and 1.5 second for stations at 180 degrees are achieved with servo indexing technology.

Under the covers, you'll find a 45 degrees true slant bed with super wide box ways, and an enormous 2-speed head stock driven by a 60 HP ( Peak ) FANUC motor.

Combined Industrial design, the perfect fully enclosed protection covers can isolates cutting chip and coolant inside the machine.

Positioning of the programmable base tailstock has been simplified through use of custom software interface. The Z-axis carriage automatically locks on to the base of the tailstock and drags it to the desired position.

The built-in bearings quill provide greater rigidity for heavyloads. The extension and retraction of the quill is programmable and thrust pressure adjustable.

Super Heavy-duty Construction

Major structural components have been combined into one solid platform. The low center of gravity 45° slant bed design provides the most rigid foundation possible for the headstock, turret, and tailstock.

By using Finite Element Methods ( FEM ), optimal reinforce ribbings are directly cast into the one-piece bed structure. Mechanical rigidity has been increased by more than 40% when compared to conventional designs. The GS-6000 series is capable of performing super heavy-duty turning and maintain long-term super high-precision accuracy. More rigidity also means extended tool life.

Built to endure years and years of rigorous high production turning, the heavily ribbed, one-piece thermally balanced bed and casting components are of FC35-Meehanite casting ( industry standard is FC25 ~ 30 ). FC35 grade cast iron is capable of withstanding much greater stress without deforming and provides maximum vibration damping, which result in a machine that will outlast and outperform the competition.

Extra wide hardened and ground box ways with C3 class ball screws.

2-speed super heavy duty gear head.

High efficiently oil mist system.

Ultimate Turning Power

With over 2,048 Nm of torque available on the low speed of the 2-speed gear head, turning tough material with big diameter is now a simple task.

Working with the living 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.

ZF Gear Box ( Optional )

GS-6000 series standard with 2-step gear box and an optional oil bath German made ZF gear box is also available. Both can provide tremendous of low-end torque to handle heavy material removal on large diameter parts.

Advanced Turret Technology

17.7" ( 450 mm ) diameter super high precision CURVIC couplings accurately position the turret disk ( ± 2 sec. of arc ) and 26,400 lb ( 12,000 kg ) of clamping force ensures abundant turret rigidity for all cutting conditions.

The 12-station heavy duty servo indexing turret achieves 0.5 second indexing times for adjacent stations and 1.5 second times for stations at the opposite end of the disk turret. Index movements are continues, without pauses, and is capable of turning 15" diameter work pieces without interference when using boring tools.

Live tooling and C-axis control capabilities on the GS-6000 series allows the machine to perform multiple tasks on a work piece, such as turning, milling, drilling, and tapping. It eliminates manpower and cycle time, while reducing accuracy lost, which will occur if the part is moved from machine to machine.
