Powerful-Hydraulic RADIAL Drilling Machine
Powerful-Hydraulic RADIAL Drilling Machine
WJR-1612DH

DESCRIPTION OF SPINDLE (Humanism front control)

The machine is designed to enhance productivity and safety by allocating handwheel,switches etc.in front of operator.The spindle adopts hydraulic pre-setting system for 12 section speed ,plus 12 step feeding functions in order to each wide range machining capacity.The spindle activating and stopping is controlled by multi-disk clutch,ensuring smooth and powerful repeated clockwise and counter-clockwise operation.
The spindle is made of chrome molybdenum steel and safety clutch is being used in the machine to prevent any damage during overloaded operations.

FEATURES

‧    Automatic feeding.
‧    Speed presetting system.
‧    Hydraulic automatic tool release device.
‧    Overload safety &protection apparatus.
‧    Humanism front control designed.
‧    The gear box adopts hydraulic control system.
‧    The spindle,radial arm, and  column can be tightened hydraulically.
‧    The spindle will be dry run when centering.
‧    High precision and heavy duty.

OTHER

DRY RUN
When centering the work-piece or release the drill,press dry run button for the hydraulic driver and makes the dry run easily.
SPEED CAN BE PRESET
The machine can preset the rpm of the next operation during machining. Then, just turn around the handle, required speed will effect automatically
TOOL SHANK RELEASE
Tool shank can be easily and quickly released simply by pushing a button; safe and efficient release increases working efficiency and will never damage the spindle or decrease bearing accuracy.
HYDRAULIC CLAMPING SYSTEM
The machine adopts hydraulic clamping system to control clamping & release of spindle unit and column continuously or separately, as is most plus for boring operation.
GEAR BOX
Apart from the chrome molybdenum alloy material applied to the gears,the gears were processed through cementing hardening and precision gringind to increase gear strength,durability and reliability.
HEAVY DUTY AND HIGH RIGIDITY
The machine is made of meehanite casting and is constructed with rib strips for extra rigidity and ensure heavy duty machining.
