STEPPED RIGID BEAM
The beam slideways are designed with a combination of horizontal
and vertical slideways which provides higher rigidity of 25% than
that of conventional slideways design with two slideways in parallel.
The upper and lower slideways are stepping structure with 300 mm.
position difference. The outstanding slideway design effectively
reduces torque created by the spindle stock and cutting force, while
assuring greater cutting force.
SUPERIOR LINEAR GUIDE WAYS
- X, Y axis employs advanced, low friction heavy duty type linear
motion guides with several slide blocks for uniform loading, no
deformation, high speed travel, high positioning accuracy and
maximum durability. The square guideways on Z-axis provides outstanding
anti-vibration performance.
- X-axis on DM25 and DM30 series machines is equipped with 3 linear
motion guides for uniform support. It eliminates deformation or
displacement problems due to uneven workpiece positioning or unblanced
loading.
DOUBLE CYLINDER COUNTER-BALANCING
SYSTEM
The specially-designed double cylinder counter-balancing system
for the spindle stock assures maximum movement smoothness on Z-axis.
HIGH PRECISION
Pretensioned class C3 precision ball screws on 3 axes upgrade rigidity
of servo system, eliminate displacement problems due to thermal
expansion, while ensuring machine accuracy at all times. Sealed
bearings combined with oil seals to fully avoid dust and coolant
ensures long service life and accuracy.
TWO-STEP GEAR VARIABLE SPINDLE SPEEDS
The spindle is driven by a high torque powerful servomotor and power
transmitted by the German ZF 2-step gearbox . The high/low speed
range makes the machine ideal for high torque, heavy duty machining
at low speed and high precision machining at high speed.
AUTOMATIC LUBRICATION SYSTEM
The machine employs a high pressure forced lubrication system in
conjunction with a volumetric oil distributor. When full pressure
is reached, all positions are lubricated properly. A feedback system
equipped on the oil tube detects if oil delivery pressure is affected
by jamming or leaking. This assures proper lubricaion on all positions.
Lubrication oil on three axes can be collected individually to avoid
mixing with cutting fluid. It not only extends cutting fluid life,
but also meets environmental protection requirements.
OIL COOLING SYSTEM
The adjustable cooling system provides cooling for spindle oil and
circulation oil in ZF 2-step gearbox. The outstanding cooling system
effectively reduces gear temprerature, ensures gearbox and spindle
service life and long term accuracy.
COOLANT NOZZLE ANGLE ADJUSTMENT
The coolant nozzle angle is conveniently adjusted on the control
panel to suit various tool diameters and lengths. This function
provides a superior cooling effect and extends cutter life.
MACHINING VERSATILITY
The machine is available to equip with manual 90° angular head,
extension head and universal head for flexible machining requirements.
