C.R. Onsrud
STANDARD Features include:
Touch
Screen
Touch Screen, open architecture, Windowstm interface option, works
seamlessly with ALL major CAD/CAM or “cabinet software”
that generates standard machine ‘G’-code.
“RISC”
Processor
All C.R. Onsrud CNC Routers are offered as standard with our 6-axis
high speed “RISC” processor, digital machine controls.
Our standard control has a remote hand-pad with “Graphics”
display that controls all machine functions from any position
around the machine that the “umbilical” will reach!
Wireless solutions are also available!
12-Position
Rotary Tool Changer
Standard 12-position rotary tool changer offers the ultimate in
tooling flexibility. The tool carousel is always accessible to
the operator to check or change tools while your router continues
to make money. With our high traverse speeds we can return the
spindle to the tool carousel in less time than the spindle rotation
can be stopped. Therefore there is no advantage in carrying the
tool carousel around with the spindle.
Shielded
Cables
Onsrud uses only the highest-quality shielded electrical cables,
designed for the constant flexing of cable-carriers, providing
many years of trouble-free, continuous, multi-shift production.
Virtually all components are user-changeable with quick disconnects.
Massive
Cast Iron Construction
Cast iron is more expensive to buy and machine, but it provides
up to ten times the damping capacity of steel. That’s why
Onsrud uses cast iron for all major components that support the
cutting spindle. Our castings are internally reinforced with heavy
ribs to resist flex and damp vibrations, and every one is thoroughly
inspected prior to machining to ensure it is free of flaws.
Wide-Stance
one-piece Base
Our base is machined in one piece (after being stress relieved)
to insure machined-in accuracy.
Get out your
tape measure and check the distance between leveling bolts. Measure
the width of the column and the depth of the saddle. Now look
inside the castings for the heavy-duty, anti-flex, vibration-absorbing
ribs that Onsrud adds. Now go measure the competition – and
you’ll find they just don’t measure up to an Onsrud.
Fast,
Reliable Electronic Tool Changer
Our unique tool changer allows the operator to inspect or even
change any of the tools in the 12-position tool carousel while
the machine continues to cut your material. Some of our competition
will tell you it is faster to carry the weight and mass of the
tool carousel with the spindle. Not so. With our faster acceleration
and deceleration we can move the spindle back to our outboard
tool carousel in less time than you can stop the spindle rotation!
Our competitor’s machines, which carry the tool carousel
with the spindle, only prevent your operator from checking tools
without stopping production, and increase your maintenance costs
by subjecting the tool changer mechanism to the harsh environment
inside the cutting envelope. With minimal moving parts, the umbrella-style
tool changer offers smooth, reliable action and long life. This
feature is not found on competing products.
Efficient
Design
When you look at the Onsrud router, you’ll find more uncluttered
room than any machine in its class. There’s plenty of room
for chips, with no hidden pockets or loose cables for them to
build up in. The optional chip conveyor conveniently discharges
them from the side of the machine.
Vibration
absorbing, non-conductive, phenolic machine tables or more traditional
aluminum tables are available on all models.
High-Speed
Brushless Motors
Brushless motors are superior to brush motors in three distinct
ways. First, standard brush motors are limited in voltage and
current values because of commutator limits. The brushless motor
can utilize twice the voltage and current, which means higher
speeds, faster acceleration and greater power.
Second, brush motors generate brush dust, which can lead to internal
shorts and accelerated brush wear. They also require periodic
maintenance to clean and replace the brushes. Our brushless motors
have no such problems.
Finally, on a brush motor, the armature, which contains the heat-producing
windings, dissipates heat very slowly through the thick, permanent-magnet
outer shell, dramatically shortening motor life. As a result,
current potential must be limited to prevent burnout. With brushless
motors, the heat-producing windings are attached to the outer
shell of the motor, allowing heat to dissipate directly to the
surrounding air, resulting in a higher duty rating from a more
compact housing.
Double-Anchored
Ballscrews
Onsrud uses only premium-quality STAR ballscrews. Our ballscrews
are anchored at both ends and inspected for 100% parallelism to
the axis guides. Pre-loaded ball nuts are used to eliminate backlash.
Hardened-Steel
Bearing Packs
Onsrud uses THK hardened-steel bearing packs rolling on hardened-steel
profile ways for each axis of every router. Built using the same
precision grinding technology utilized in bearing manufacturing,
these bearing packs feature zero clearance and full load-carrying
capacity in all directions. They consume less power, do not require
any adjustment and are proven to outperform sliding box ways for
accuracy and speed. Profile Ways are used by every “high-end”
machine tool builder today.
High-Capacity
Cartridge Spindle
The advanced, four-bearing spindle design used for our HSK-63-F
taper spindles provides high radial thrust capability, yet generates
minimal heat. We accomplish this by finishing the front and rear
bores of the housing and grinding the OD of the spindle in one
operation. This guarantees perfect alignment between bores and
ODs, thus reducing bearing heat.
Additionally,
the two forward 50 mm angular contact bearings are separated by
a 10 mm spacer to enhance radial stability – enabling heavy
cuts. To ensure long life, the spindle is pressurized with air
to prevent contamination.
Powerful
12 to 40 Horsepower Spindle Drives
These top of the line drives allow you to push the spindle to
150 percent of the motor’s continuous horsepower for a full
minute. That’s more performance headroom than any other drive
on the market.
Although
our premium components are more expensive than our competitors’,
the use of premium componentry is the only way to achieve the
high accuracy and long life that our customers demand.
