High Rigidity Structural Design

  • One piece T-type base structure with rib construction for unprecedented rigidity.
  • Dual-wall column design for enhancing rigidity and durability.
  • Adopted FEM analysis for lightweight design to improve G value that can prolong ballscrew life and reduce energy consumption.

Stepped Design on X-axis

  • Two X-axis guideways are positioned at different height to increase stable and reliable rapid axial movement.
  • Compact column design is able to achieve higher acceleration and performance.

All Roller Type Guideways

  • XYZ axes are equipped with roller guideways to increase rigidity and accuracy.
  • High dynamic AC servo driven pre-tensioned ball screws, delivering high control qualities.

Powerful IDD Spindle

  • The standard IDD spindle design, easy for maintenance 15,000 rpm max. spindle speed with 37 kW output delivers 244 Nm torque.
  • The powerful spindle utilizes high precision ceramic ball bearings.
  • The spindle oil cooling system effectively minimizes thermal deformation.

High Performance Built-in Motorized Spindle (opt.)

  • The max. spindle speed reaches up to 20,000 rpm with 22.5 kW output delivers 61 Nm torque.
  • Micro oil-air lubrication for angular ceramic ball bearings prolongs spindle life.
  • Circulated oil jacket cooling system minimize thermal deformation, ensuring high accuracy.
  • Easy spindle unit replacement reduces maintenance time.

Optimized Spindle Design

  • Coolant through spindle system: 20 bar (std.) / 70 bar (opt.).
  • Spindle air seal protected.
  • Labyrinth protection design.

BBT40 Dual-Contact Spindle Taper

  • Equipped with BBT dual-contact to improve cutting capacity and accuracy, also enhance spindle and tool life.

Reliable Automatic Tool Change

  • It takes 2 seconds to complete one cycle of tool to tool change.
  • ATC speed is programmable in high & low speed.
  • Servo motor driven tool magazine.
  • 60T for disc type tool magazine (std.).
  • 120T for chain type (opt.).

Automatic Pallet Change

  • 11-second pallet change servo motor driven.
  • Maximum table rotation speed: 22.2 rpm/min

Dependable Pallet Indexing System

  • Flange contact taper cone with excellent clamping power and high pallet-positioning precision.

High Efficiency Six Pallets System for Flexible Production Needs (opt.)
