YCM L Series turning centers have a robust one-piece base casting to help distribute cutting forces, reduce vibration, and structural deformation. Multiple configurations available, from 2-axis to multi-axis turning, static to live-tool turrets, programmable tailstock to sub spindle making the L Series an excellent choice for middle to upper range components.
Robust One-Piece Base Structure
One-piece 45°slant bed design made from high quality cast-
iron helps with distribution of cutting forces throughout the
machine bed providing better absorption of vibration and
reduced structural deformation, while also enhancing chips
and coolant flow.
Spindle Benefits
The turning center is equipped with up to 25 hp (18.5 kW)
spindle with rotation of up to 4,500 rpm. It includes an 8” chuck,
ø2.04” (ø52 mm) hole through draw tube and expanded travel
of Z-axis that means a spacious working area is provided for
large workpiece up to ø15.74” x 23.62” (ø400*600 mm).
BMT55 Turret with Live Tooling
The BMT55 turret ensures a fast and stable rotation of up to
6,000 rpm and outputs 5.0 hp (3.7 kW). The 12-station servo-
driven turret provides high reliability and reduces tool change
time. Next tool index is 0.4 sec. and 180° index is 1.5 sec.
Tailstock
This fully programmable MT5 tailstock has 3.93” (140 mm) of
quill stroke with a quill diameter of 3.34” (85 mm) and a stroke
of 23.62” (600 mm) allowing long shaft work to be performed
on this versatile machine
