GT Series

● GT Series is developed for aerospace, mold, and automotive parts machining. According to the machining requirements, 15,000/ 20,000/24,000 rpm spindle are both available for selection.

● Gantry type structure, the control of three linear axes, wihch are free from affect of workpiece weight, and the driven centers of three axes are all on these gravity center. It significantly improves dynamic stability.

● The optimized force route design on spindle saddle, it minimizes spindle overhang and improves the stability and rigidity during machining.

Driven at the center of gravity

● The driven centers of three axes are all on these gravity center. It dramatically improves dynamic stability.

● The shortest force route between Z-axis and X-axis to optimize the weight of structure and increase machining rigidity.

● An enclosed structure design enhances complete structure rigidity.

● The gravity center of Y-axis moving is in the center of complete saddle falls within the supporting range of sliding block, it avoids spindle overhang and improves dynamic stability.

Movable type stable Fixed type table

Fixed type table designX/Y/Z axis moving and table rotation are working individually to make sure machining is free from 3 axis inertia influences. Prefect servo driven design gives excellent machining stability. Comparing with table moving type, A/C axis are equiped in fixed position, A axis positioning accuracy can be free form vibration by feeding axis.

Operation

Well chip flowCentral chip flow design, chips can be carried out immeditely while machining. It prevents casting struccture from being affected by hot chips and main-tains machining accureacy.

Distance of tool changingThe excellent access for tool changing and checking.

Door opening widthWide door opening facilitates the operation and

maintenance.

The automatic open top telescopic cover of Y axis is convenient for lifting works.

Open top telescopic cover

Swivel-type operation panelThe swivel panel enables operator to operate and inspect easily during opera-tion.

Easy daily maintenanceThrough centralized mangment of air FIRL unit and lubricant pump, daily maintenance is made easily.

Accessory specifications

Short chips : The chip length is smaller than 60 mm or Ø40 mm (ball shape cutting).Long/Curl chips : Chip is longer than short chips mentioned above.

Chip conveyor (Opt.)

According to different materials and chip size, Tongtai provides various chip conveyors for the best chip disposal.

Linear scale (Std.)

With linear scales in X/Y/Z axis, that is able to compensate posi-tioning errors, repeatability errors, and ballscrew pitch errors caused by temperature. Positioning accureicy cmn be martained in ±5 µm. Further option for ±3 µm liner scale id also availabile.2 µm and 5 µm rotary scales is standard equiped in A and C axis to garantee rotary positioning accuracy.

Chip disposal (Std.)

Comprehensive bed flush make sure all chips flow out. Various type chip conreyors are available for different materials disposal.

● Built-in type temperature sensor detects the temperature of spindle bearing for protecting the bearing from overheating.

● By measuring temperature of the nearest point to bearings, compensation can be adjusted accordingly.

● Through thermal compensation, precision of each axis can be maintained below 20 µm.
