YAMA SEIKI

Advanced Turret Technology

Standard Turret

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

Live tooling turret and C-axis control capabilities on the GV-780 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.
