Sub-spindle supports precise rear-side machining in a single setup.
One-piece 30° slant bed provides high rigidity and excellent chip evacuation.

Product Introduction

One-Piece Casting Bed

One-piece 30-degree slant bed made out of gray cast iron, which has superb vibration absorption characteristics, provides rigid foundation for all machine components.
Such design endures long-term machining accuracy and consistency.

Main Spindle

Double row cylindrical roller bearings in the front and back, coupled with angular thrust bearing, ensure high rigidity for heavy cutting and excellent surface finishes.

Sub Spindle (SY Models)

The sub-spindle with full C-axis control enables precise machining on the rear side of the workpiece. Its powerful built-in motor with an oil cooling system delivers fast acceleration, high torque and exceptional precision.

12-Station Turret

The 12-station turret with 24 index positions (half-indexing) offers increased tool capacity. The turret design incorporates a 245 mm large-diameter Curvic coupling, delivering powerful clamping force of 83.8 kN (18,839 lbf) to ensure high rigidity and enhanced cutting performance.

Tailstock (Y Models)

Programmable tailstock body & quill make easier to adjust tailstock position and minimize setup time. MT#5 built-in live center tailstock provided as standard, ensures superior machining rigidity.
