The new SF Series Bridge mills features: (3) new Y axis options, 47”, 63” and 78”, with an X axis selection from 80” to 162” and Z axis
of 31.5” This new narrower Y axis machine has roller linear ways on X
and Y axis for faster feed rates and rapid traverse but still maintains
a very rigid Z axis with box way construction. The spindle speeds are
offered at 6,000 RPM with 35 HP and a 2 speed headstock, 10,000 RPM
with a direct drive spindle that is directly coupled to the spindle
motor for added rigidity and excellent acceleration and deceleration
rates. There is also a 20,000 RPM direct drive spindle for the mold and
Series machines come with 40 ATC and a fast cam-type ATC (3 sec
tool to tool), Full CTS (300 PSI), Spindle chiller and ball screw
support systems on machines 160” (4 Meters).
years of robust and accurate machining, SF bridge mills also sport
heavy duty casting, large sized supporting columns and cross beam, step
square beam and saddle. The table is ground for superior accuracy and
longevity. The Z axis has self-aligning twin hydraulic counter balance
system that ensures high speed movement without excessive loads on the
axis and motor.
Standard Features: Fanuc
18i MB, 6,000 rpm 2 step gear spindle, spindle and gear box cooling,
40 tool ATC, independent lube in X / Y / Z, full splash guard, air
blast through spindle, flood coolant. Options:
8K, 10K, 20K spindles, CTS of 300 to 1,000 PSI, 60 tool ATC, linear
scales, 200/300/400 mm column extension, full enclosure splash guard
with top cover, spindle probes and tool measuring probes.
SF series machines, with typical VW products features of rigid structure and high precision, are designed with direct-driven X-Y transmission device and torque enlarger unit on X-axis, increase the X-Y moving accuracy and offer the combination control of speed and precision.
Twin Hydraulic cylinders plus pressured nitrogen accumulator balancing design provides smooth & accurate feeding performance. Z-axis can reach 0.5G acceleration and keep a holding position at power failure.
Heavy duty roller ways on X-Y axis contain the advantages of low friction and high stiffness.
High stiffness light-weight table design, ensures high acceleration/deceleration when loading.
Y-axis upper roller way is positioned on the top of beam at max. span design offers strong supporting.
Torque enlarger unit on X-axis increases the transmission torque and ensures the transmission accuracy.
