MACHINE FEATURES

ISO 9001 Quality Assurance.
Class 7 Bearing for spindle run out less than 0.00015".
Spindle Motors are 220V, 10HP (M218), 15HP (M320, M422 & M526), 20HP (M632).
Electronic Vari Speed Spindle Motor with Encoder.
Hardened & Ground Table / Center T-Slot (Ground for Quick Setting).
Meehanite Casting to provide maximum rigidity and stability.
Square Slide Ways on X, Y & Z-axis.
The axis motors are Directly Coupled to the ballscrews (except M632). It reduces backlash and ensures long lasting accuracy.
X, Y & Z-axis Metal Telescoping Way Covers.
4 Box Ways design on Y-axis for long-term reliability.
Super Wide Saddle to ensure accuracy movement.
All axes have high precision, Class C3, pre-tension Ballscrew to ensure high accuracy.
Hardened & Ground X, Y & Z-axis Way with Turcite B coating to eliminate stick-slip.
ATC Umbrella Type Tool Changer or Arm Type Tool Changer.
The tool change time is only 3 sec. (tool to tool).
CAT 40 or BT 40 Spindle Taper on M218, M320, M422 & M526. CAT 50 or BT 50 on M632.
High precision spindle is supported by three sets of high precision P4 class angular bearing and to assemble W/- four pieces of clamping collet.
The spindle is driven by high torque and lower noisy 8YU belt.
Automatic Flood (M8) Coolant System or Mist Coolant (M7). Specify at time of order.
Laser Compensation to ensure high accuracy +/- 0.0004" position 0.0002" repeatability.
Finite Element Analysis (FEA).
Machine made in Taiwan.
