GV-500M - High Speed Vertical Turning Center

High Speed Vertical Turning Center

Packed with the latest machine tools technology and high precision turning capabilities, the YAMA SEIKI GV-500 series high speed vertical CNC turning center combines a high rigidity structure and precision linear guideways with a servo indexing turret and powerful spindle ( max. torque up to 883 Nm ). These series features a compact machine size with heavy duty turning capabilities. In addition to the GV-500 series, the GV-500X series twin spindles & turrets equipped with loading & unloading systems can complete disk-shape work pieces that need multi-processing in one single setup which saves a great amount of time and increases production efficiency to meet your needs of today and tomorrow.

Fully enclosed splashguard keep chips and coolant contained for a safe clean working environment.

The low center of gravity design with 90 degree rotatable control panel provides easy access to load & unload parts and a user friendly operating interface.

Super compact machine size ( 3.3 m² ) equipped with rear discharge chip conveyor increases factory space usage while providing you with a convenient conveyor system planning.

High Rigidy Structure

By using Finite Element Methods ( FEM ), optimal reinforced ribbings are directly casted into the one-piece bed and column structure. Mechanical rigidity has been increased by 30% when compared to conventional designs. The GV-500 series is capable of performing heavy-duty turning and maintain long-term high-precision accuracy. More rigidity also means extended tool life.

Built to withstand years and years of rigorous high production turning, the heavily ribbed, one-piece thermally balanced bed and column are of “ Meehanite ” casing.

The Japanese high precision linear guideways provide maximum precision, rapid movement and low-wear advantages.

The servo motor of each axis feed system uses FANUC αi series components to ensure peak machining performance and accuracy.

The auto lubrication system uses an pressure relief lubrication device and copper oil pipe, providing slide ways, ball screws and other major components abundant lubricant.

Extra wide slant surface chip disposal design allows easy chip removal, preventing the heat from influencing machining accuracy.

Contact surfaces of all slides, spindle, turret, and ball screws bearing housings with the machine bed and column are precision hand scraped to provide maximum assembly accuracy, structural rigidity, and load distribution.

Ultimate Turning Power

The wide-range FANUC αP30 / 6000i motor driven spindle system can generate twice the torque output of standard motors.

Optional German made oil bath gear box is also available, providing maximum torque of 1,821 Nm.

Advanced Turret Technology

The super heavy-duty servo indexing turret features the latest non-lifting turret disk technology, achieving 0.2 second indexing for adjacent stations and 0.5 second for stations at the opposite end of the disk.

The Japanese super high precision curvic couplings accurately position the turret disk and 3,620 kg ( 7,240 lb ) of clamping force ensures abundant turret rigidity for all cutting conditions.

The curvic couplings features auto-centering, auto-cleaning and a large size tooth flank which are superior to traditional curvic couplings and are greatly used in our products.

Live tooling turret and C-axis control capabilities on the GV-500 series allows the machine to perform multi-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.

Each station of the live tooling turret can be equipped with live tooling ( live tooling tools rotate in working position only ) and features a non-lifting turret disk.

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

Dual-Face Turning Holder

The YAMA SEIKI dual-face turning holder allows both sides of a work piece to be machined at the same time while ensuring parallel precision of the surface, which is applicable for disk brakes or automotive related components.

The cutting time is 50% shorter than when using regular tools.

The servo motor driven dual face tool holder provides more flexibility to various working conditions, overcoming hydraulic driven disadvantages, thus, saving tool adjustment time and increasing production efficiency.

Twin Spindles & Turrets Vertical Turning Center

The twin spindles & turrets vertical turning center is based on a “ combining two operating process into one ” concept. Therefore, the 1st spindle and 2nd spindle can work independently on two different work pieces or work on the 1st and 2nd process of one work piece, efficiently lowering the demand on manpower and increasing factory space usage.

The GV-500X series can be equipped with optional load & unloading systems and work piece flipping device are also available. From bar feeding, processing, flipping, processing and discharging, can all be completed at once which saves manually flipping time and reduces setting error and increases production efficiency.

Work piece flipping device : Max. work piece diameter Ø 430 mm, Max. work piece weight 40 Kg

The GV-500X series combines two work process into one to reduce operating time ( when working on two machines ) and increase production efficiency.

When the detection gate on the bar feeding conveyor detects a work piece passing through, it will close immediately to prevent another work piece from entering the back rail, providing high reliability and safety.

The flipping device uses a pneumatic clamping and hydraulic rotating mechanic design which features high speed and heavy duty advantages.

The 3-jaw clamping device on the turret uses triangulation support to ensure the work piece to accurately adjust to the center of the spindle while ensuring turning accuracy.
