Massive, rigid 30゜Slant Bed Construction

Rigid Machine Structure
● The 30゜slant bed is one-piece manufactured from high quality Meehanite cast iron, tempered and stress relieved. This results in maximum stability of structural material and deformation-free performance for years.
● The structure is analyzed by 3D Finite Element Analysis to achieve superior rigidity.
● Extra wide box ways on X, Z-axis are excellent for heavy cutting. The box way surfaces are hardened and precision ground, then coated with TURCITE-B. These box ways provide outstanding wear resistance and make the machine ideal for heavy cutting.


Hydraulic Turret
● The hydraulic turret is driven by hydraulic indexing motor, which is combined with the use of high precision clutch for positioning. This design provides fast and accurate tool change.
Gear Box (opt.)  
● The rigid gearbox body combined with Japan imported gear, that are manufactured from Cr-Mo alloy steel, precision ground and carburization treated, These excellent gears provide high efficiency, low thermal growth and low noise transmission features.
Rigid Spindle Headstock  
● The massive spindle stock construction assures outstanding stability when performing heavy cutting.
High Precision spindle
● The spindle runs in roller bearing and high precision angular contact ball bearings, providing superior axial and radial loading capability under heavy cutting conditions.
Hydraulic 3-jaw Chuck  
● The hydraulic 3-jaw chuck is standard equipment.
● 3-jaw chuck diameter varies with the machine model 10"/12"/15" to choose from.
● Afoot switch is provided for controlling chuck clamping and unclamping, providing added convenience and efficiency.
Hydraulic Tailstock  
● The tailstock quill movement is actuated by hydraulic system for convenient work piece clamping.
Programmable Tailstock (opt.)  
● The tailstock quill movement can be controlled by programs to save manual operation and time, while upgrading efficiency of operation.
