Double Column Machining Center

Double Column Machining Center:
DV14 series Double Column Machining Center that fully combines heavy cutting and high-speed machining capabilities in one. The DV14 series is a profitable performer, especially excellent for precision machining for extra heavy parts. To ensure maximum stability when handling heavy parts machining, the five major structural parts of the machine are manufactured from high-quality Meehanite cast iron and ductile iron. The specially designed machine structure enables the machine to keep at the best accuracy condition after years of operation. With the roller-type linear guideways on the X, Y, and Z axis, the machine fully exhibits its heavy loading resistance and outstanding features.

To meet the high-speed, high-precision machining requirement, the DV14 series employs a direct-drive high-speed spindle. This combines with a high/low-speed gearbox for transmission with a wide speed range. It makes the machine ideal for high-speed machining. In addition, the gearbox also provides high torque output, permitting the machine to perform heavy cutting with ease. The spindle head on the DV14 series is designed with an advanced automatic compensation balancing system combined with the use of an accumulator to control the hydraulic cylinder, allowing the spindle to move smoothly and steadily at all times.

Features

ROLLER TYPE LINEAR WAYS ON THREE AXES
  • All major structural parts are manufactured from high quality cast iron with tempering tread to relieve stress, ensuring maximum material stability without deformation.
  • Box type structural parts are rib reinforced to increase structural strength and rigidity.
  • Extra heavy base complete support of table and resists heavy load without deformation.
  •   X, Y, Z axis are mounted with roller type linear ways combined with extra wide between ways for added stability.

RIGID SPINDLE HEAD
  • The spindle head is a box-type construction that increases stability when performing heavy loading.
  • The linear ways on Z axis are specially designed with side layout to upgrade rigidity of the spindle head.

GEAR BOX
  • This spindle running is transmitted through a gear box, making the machine excellent for heavy cutting applications.
  • Wide spindle speed range from 10 to 6,000 rpm permit the machine to perform heavy cutting and fine finishing.
  • All gears and bearings in the gear box are oil-bath lubricated.

32 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 ISO 50 tool shank.
  • The magazine is separately mounted from the cutting area combined with a protection door to prevent tools contamination from chips or coolant.

CHOICE OF VARIOUS MILLING HEADS

THESE MILLING HEADS ARE OPTIONAL

PNEUMATIC BALANCE ON Z-AXIS

The Z-axis movement is counter-balanced through a pneumatic counter-balance system. An accumulator is equipped in the air circuit, ensuring fast and stable movement of Z-axis.

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 augers to a chip conveyor for exhausting chips outside the machine.
