SD series Tool System

SD series is designed with maximum performance, minimum floor space and easy to operation. Also available with live tooling, sub-spindle and C-axis to provide the mostly friendly working condition.

SD series is design with pneumatic system instead of hydraulic system to achieve our goal that with environment friendly, safety and easy to maintenance.

X and ZB axes, the guide ways is dovetail box way that made under heat treatment and super high precision grinding. And the slide ways are bonded with Turcite B to eliminate stick-slip, minimize wear and maintain long term accuracy.

Other axes are using high precision linear guide way. It provides high accuracy positioning no matter it is in high or low speed.

Contact surfaces of X and ZB slides, headstock and ball screw bearing housings with the machine bed are hand scraped to provide maximum assembly precision, structural rigidity, and load distribution.

For top component precision, YAMA SEIKI utilizes top-end measuring and balancing equipment such as; ZEISS 3D measuring system, BL high precision dynamic balancer and many more.

SW series Tool System

SW series offers more flexabile operations such as turning, milling, and cross drilling. From a different combination of power systems, main-spindle, sub-spindle, front-end tool, rear-end tool, C-axis and live tools which means the workpiece can be finished at one time and also allows two operations to be machined simultaneously.

*1 The uppper 3 positions are a fixed unit for milling and drilling and the buttom 2 positions allow variations to be fitted. ( For SW-20 / SW-32 )
    The uppper 2 positions are a fixed unit for milling and drilling and the buttom 2 positions allow variations to be fitted. ( For SW-42 )
*2 The buttom 2 positions can be increased up to 5 front-end and 2 rear-end live tools.
*3 Live tools are available.

Spindle Construction

Spindle can be exchange to be bush type or bushless type which is depend on different work requirements.

The bushless design which is suitable for machining cold forge bar and the remain bar can be less than 50 mm to save material cost.

The bush type can be rotate with high speed which can less surface damage and efficient increase working performance.

The Sub-spindle is with FANUC built-in motor and C-axis control, which can be simultaneous with main spindle perfectly to maximum machining accuracy.
( SW-32 only )

Sub-spindle applied 2 deep hole drill devices which can increase tool number and make tool selection more flexible. ( SW-32 only )

Based on different application, the side rotary toolholder can select different live tool attachment, such as for OD grooving, polygon machining or standard rotary toolholder.

All axes are using high accuracy linear guide way to ensure the most stabilize and provide ultra high performance in moving and positioning. Beside, guide way are pre-load to eliminate any backlash occurs during high speed moving.
