Tongtai DC-350 is especially designed for differential case machining. For ensuring excellent machining accuracy, the workpiece only needs one-time clamping and all machining tasks are able to be finished in one single machine .Furthermore, through the collaboration of two spindles and two tool magazines, it dramatically saves the machining time.

Most of the aerospace parts have feature of large size, complex shape , hard to cut and high precision . We work with different manufacturer to develop the specific Equipment subject to aerospace industries including 5 Axis Vertical & Horizontal Machining Centre , Gantry Type Machining Centre , Vertical Machining Centre , Vertical Turning Lathes & High precision Grinding Machines for Engine parts , aircraft body, die mold & fixtures.

Tongtai is 50 yrs old company from Taiwan.

Tongtai Machine & Tool Co., Ltd.(4526. TW) is a machine manufacturer with the biggest scale among TTGroup’s members, and also is the listed company with the highest revenue among Taiwan’s machinery manufacturing groups.

Wide Range of Vertical Machining Centre , Horizontal Machining Centre , Turning Center, 5-Axis Machining Centre and SPM for the Automobile Industries .

High rigidity structure & Wide span column with the best force flow route ensures the machine rigidity.

Through finite element analysis (FEA), the static, mold and optimization analyses of structure were processed for ensuring high dynamic rigidity and stability.

Tongtai self-made built-in spindle (optional) ‧Maximum spindle speed 20,000rpm ‧Oil-air lubricated bearings and the floating sleeve on rear-end bearing are able to reduce thermal generation and avoid thermal expansion that affects machining accuracy and bearing life.

Ball Valve Size : Ф2 Inches – 64 Inches .

SMG spherical milling machine is a ball grinder. T shape back seat, C shape column with good tensile strength and rigidity. Recommended for ball valve industry.

The rotary table is seated on the sliding carrier and the ball on the rotary table, the grinding tools are installed in the spindle. Both tool and the ball rotate when grinding.

Work piece to be mounted vertically on the worktable to avoid deformation and protect bearings .
