OPTIMAL STRUCTURE DESIGN

Equipped with rotary table.
  • The major structural parts are manufactured form high quality Meehanite cast iron (GB 300), tempered for stress relief with hardness over 190HB.
  • The structural parts are tempered for stress relief that ensures deformation-free performance year after year.
  • X, Y, Z axis are mounted with roller type linear ways, exhibiting extra high rigidity and loading capacity.
  • Oversized column structure dramatically increases machining stability.
  • Fixed column construction.
ROTARY TABLE
  • HIGH ACCURACY The rotary table employs three-piece teeth plate for high accuracy indexing.
  • HEAVY-CUTTING RESISTANCE The three-piece teeth plate combined with hydraulic locking mechanism allows full teeth engagement. This results in higher rigidity and increased heavy cutting capacity.
COOLING THROUGH SPINDLE (OPTIONAL)

Coolant circulates through spindle offer a direct cooling effect on tools, removing heat that occurs during machining. Combines with filter tank system (optional).

TWO SCREW TYPE CHIP CONVEYORS ON BASE

There are two screw type chip conveyors provided at right and left side of the base. During cutting, the chips are delivered through these chip conveyors for exhausting chips outside of the machine.

CHAIN TYPE CONVEYOR (OPTIONAL)

The chip conveyor is available to be mounted at the backside of the machine. It removes chips efficiently.

40 TOOLS CHAIN TYPE MAGAZINE (STANDARD)
  • The magazine is driven by a precision cam, featuring fast and accurate tool positioning.
  • Tool selection is bi-directional and random for fast tool change.
  • The magazine accepts ISO40 tool shank.
  • The magazine is separately mounted from the cutting area combined with a protection door to protect tools from contamination from chips or coolant.
HYDRAULIC BALANCE SYSTEM

The Y-axis movement is counter-balanced through a hydraulic cylinder. An accumulator is equipped in the hydraulic circuit. This counter-balance system will reduce spindle head vibration to a minimum, while significantly improving machining accuracy.

DUAL PITCH WORM / WORM GEAR SET

The transmission mechanism employs high efficiency " Dual Pitch Worm / Worm Gear Set " for increasing teeth engagement percentage. This outstanding feature offers increased efficiency and wear-resistant capability.

HOLLOW BALL SCREW WITH COOLING SYSTEM
  • Three axes are transmitted through class C3 high precision high speed, no-noise ball screws.
  • Ø36mm, ball screws are pretensioned and preloaded to minimize deformation.
  • A laser unit is applied to calibrate the machine accuracy to ensure machining accuracy.
  • Coolant through ball screws on X, Y, Z axis minimizes thermal deformation and backlash, while ensuring smooth motion during rapid traverse.
