Structure: The base, column and headstock
are heavy duty Romi castings. They are well ribbed for
strength and vibration dampening. Both the column and tables
are supported by the monobloc base. The castings are poured
in our own foundry to DIN 1691 standards. Our foundry is
ISO 9002 certified and has been since 1994. The base casting
is designed so that chips will flow away from the work
area.
Headstock: The headstock casting is designed to provide
minimal deformation under load and ambient thermal variations
using finite element analysis. The spindle motor is isolated
form the headstock casting using thermal insulation. The
motor fan directs exhaust air upward away from the headstock.
The headstock casting has a wide stance across the linear
guide ways and a long contact area to minimize deflection.
The spindle housing part of the headstock casting has an
air space around the spindle housing to dissipate heat.
An ambient temperature increase of 40 degrees results in
a Y axis angular displacement of less than .0018”.
The headstock casting is so rigid that there is no need
to build in sag or torsion in the casting as many competitors
do. Since there is no counterbalance the Z axis thrust
is augmented by the weight of the headstock.
Spindle: Romi spindles are assembled in Romi’s ultra
clean room which has less than 5 microns of dust per cubic
meter. Romi uses three angular contact precision ball bearings
around the tool taper and a roller bearing at the upper
spindle area. The 10,000 RPM spindle uses ceramic ball
bearings to minimize heat, provide higher continuous RPM
and greater load capacity.
Guide ways: Preloaded linear guide ways are used on all
axes. X and Y axes guide ways are protected by sliding
steel guards.
Tool changer: The umbrella changer holds 22 tools and
uses plastic tool grippers. The grippers are inexpensive,
easy to replace and softer than any tool holder to prevent
damage and wear to the holders. The grippers reduce the
weight in the umbrella allowing you to use heavier tools.
Double proximity switches are used to insure positive location
of the tool disc.
Ball Screws: Ball screws are manufactured and ground by
Romi where complete control over the accuracy and quality
is insured. We are not dependent on commercially available
products. The double ball nuts are large in width and diameter.
The double nut design provides positive location by mating
with both flanks of the screw at all times. This design
also minimizes heat distortion. Thermal gauging or temperature
reduction systems are not required.
Lubrication: Automatic lubrication is standard. The lubrication
reservoir is in plain sight and is easy to refill, but
it is protected from accidental damage. The reservoir has
1/2 gallon capacity.
Guarding: Romi uses 10 gauge, powder coated steel for
all external guarding. The door is easy to open and close
gliding on multiple rollers. The double overlapping seal
ensures that coolant remains in the cutting area, not on
your floor. A large safety window in the door and large
side windows allow the operator to monitor machine operations.
Steel guards direct chips to the sides of the work area
where they are collected in easy to clean chutes. A sealed
work light is located in the work area.
