High Speed Turning Centers

Packed with industry leading technology and top quality components, the YAMA SEIKI GLS series turning centers combine power, strength, and speed to bring you The Ultimate Machining Power®. These high speed machines will easily accomplish the demanding turning applications of today and tomorrow. Furthermore, with available live tooling, C-axis, and Y-axis capabilities; milling, turning applications may be completed in one single machine.

30˚ slant-bed design provides smooth chip disposal and easier operator access.

Stainless steel way covers and special steel wipers molded with industrial strength rubber are used for durability.

ully enclosed splashguards keep chips and coolant contained for a safe clean working environment.

The auto lubrication system delivers metered amounts of lubrication to the slide ways, ball screws, and vital components. Distribution is automatically shut off during idling to prevent waste.

( Opt ; For Y models )

Y-axis models perform virtually the same way as machining centers equipped with 4th-axis rotary tables, but with the benefit of built-in turning capability. The X, Y, Z axes are like that of a machining center, while the C-axis acts as the 4-axis. This configuration replaces a turning center and machining center equipped with 4th-axis with one machine, thus, saving money, time, floor space, manpower and fixture costs, while reducing accuracy lost by eliminating the part from being moved to another machine.

( Opt ; For M models )

Live tooling and C-axis control capabilities on the GLS 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.

Maximum Strength Construction

Built to withstand years and years of rigorous high production turning, the heavily ribbed, one-piece, thermally balanced bed and casting parts are of “Meehanite” casting. The 30 degrees true slant bed design further provides superior support for the headstock, turret, and tailstock, thus, creating the rigidity needed for long-term high precision turning and efficient chip removal.

Major structural components have been combined into one solid platform. The low center of gravity 30° 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 30% when compared to conventional designs. The GLS series is capable of performing heavy-duty turning and maintain long-term high-precision accuracy. More rigidity also means extended tool life.

Ultimate Turning Power

The heavy-duty headstock is of one-piece casting reinforced with heat dispensing fins.

Standard rigid tapping feature provides high-speed precision tapping without the use of floating tap holders. Set-up is easier and depth of thread more accurate, permitting maximum productivity for tapping operations.

The precision direct belt drive system provides greater spindle control, flexibility and serviceability. Pulley ratios fine tune the motor’s maximum RPM to match the spindle’s maximum RPM, which result in full output at the lowest RPM possible. Thus, utilizing the full potential of the spindle motor for maximum cutting power.

P4 grade ( Class 7 ) super-high precision bearings are directly assembled for maximum level of support and precision. Bearing configuration is designed for heavy-duty cutting with ultra-smooth performance and long term durability with a higher level of accuracy.

GLS-150 models are available with built-in spindle motors, which eliminate traditional belts and pulleys. This advance system provides faster spindle response, reduce vibration and power lose, which translate to faster cycle times, higher accuracy, and lower maintenance costs.

Advanced Turret Technology

A high-speed servo motor indexing system provides the 10 or 12-station turret with a 0.2 sec. indexing time. Large diameter high precision curvic couplings and hydraulic clamping is used to enhance tool indexing accuracy and turret disk rigidity.

The standard 10-staion turret clears 8" diameter work holding devices without interference while the 12-station turret clears 6” diameter devices.

The standard hydraulic tailstock uses live centers to provide support for long work pieces. Quill pressure is adjustable and movement is programmable.

The optional servo driven tailstock uses a servo motor and ball screw to position the tailstock and generate pressure to support the work piece. Pressure against a work piece is adjustable by increasing or decreasing the load of the servo motor, which can be programmed to provide variable and precise pressure during the machining process. This type of tailstock can also be used to drill the work piece during the OD turning process.

Multi-tasking Live Tooling Turrets ( For M Modle )

Live tooling and C-axis control capabilities on the GLS 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 6 stations available for live tooling.

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.

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, 2.75” =±1.37”( 70 mm=±35mm ), 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. Guide ways widely spaced for maximum strength.

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