Centerless Grinder
TG 12x3 /TG-12x4 Series
CG 12x3
TG-12x3 and TG-12x4 series can be
equipped as an infeed or thrufeed
machine, or a combination of both.
The TG-12x3 has a 12 inch (304mm)
diameter and a 3 inch wide (76mm)
grinding wheel, and the
TG-12x4 has a 12 inch (304mm)
diameter and a 4 inch wide (100mm)
grinding wheel. Both models have
single point diamond dressing
capabilities and the ability to hold
micron tolerances.
Royal Master’s Crush Grinders are
manufactured in both 3 and 4 inch
wide (76mm and 101mm) wheel
faces with crush capabilities up to
three inch (76mm) profile lengths
on both models. Our crush grinders
have additional versatility with
single point diamond dressers for
both the work and regulating wheel.
Both machine models are highly
versatile with the ability to grind
multiple steps diameter parts.
Equip the system with an automatic
infeed unit, and automatic loading for
unattended operation. Other popular
options include Microsize systems
with glass scales, Laterial Regulating
Wheel adjustment, Superabrasive
Grinding wheels, HI-Accuracy
systems and CNC Dressing.
In the last 20 years, Royal Master is world reknowned
as specialists in making centerless grinders and providing
solutions for the most difficult grinding applications. Our
machinery grinds products in the .001" to 1.5" ( .05mm to
38mm ) diameter range.
CG-12x3 / CG-12x4
Crush forming is an accurate
technique for placing a form into the
grinding wheel. Often a configuration
may not be dressed into the grinding
wheel using a single point diamond
and template form, such as a small
radius adjacent to a 90 degree
shoulder, a flange in the middle of a
part, or a slot; whereby crush form infeed grinding is required.
DWT-12x4
Now you can infeed grind carbide, ceramic, and other hard materials
requiring a super abrasive grinding wheel and still have all of the convenience and speed of redressing a conventional abrasive type wheel.
This truing feature allows for the
mounting of a diamond work
wheel to the machine, having it
trued to the spindle, and re-trued
as needed in minutes without ever
having to remove the wheel from
the machine.
DRF-12 x 3 & DRF-12 x 4
Royal Master’s diamond roll form
grinders are manufactured in both
3 and 4 inch (76mm and 101mm)
wide wheel faces with diamond roll
form capability up to 3 inch (76mm)
profile lengths on both models.
Diamond roll form dressing is an
ideal solution for rapid dressing
of high volume intricately shaped
parts. This accompanied with automatic size compensation
between dresses provides the user the opportunity to narrow
the total tolerance range on a given part.
The Royal Master Model DWT12x4, is specially built to include
an extended machine bed for a
permanently mounted diamond
wheel dresser.
The diamond wheel dresser is PLC controlled with x and y
slideways and a reciprocating rotating diamond disc. The wheel
dressing function will be initiated on demand by the touch of one
button. Once activated, the diamond wheel dresser will perform a
preprogrammed dress function and then reset itself for the next
dress requirement.
Since its introduction in 1999 the
Generation 5.1 CNC Guidewire
Grinding machine has become the
choice of companies around the world
for their production Guidewire
Grinding requirements. The system
with its sensors spaced .0025” apart
make for the most accurate
tapers without any radical offsets or
calculations to make tapers “fit”.
The Generation 5.1 is the standard in the
industry for grinding Guidewires with anything from long single tapers or up to 15
tapers, at a production rate of 1” (25mm)
per second. The longevity of the Royal
Master Systems are world renowned as
many of our first Generation 1 and 2
systems are still grinding production.
The Royal Master SA-449 Laser Gauging system gauges guidewires or
other small diameter applications and displays their length and diameter dimensions pictorially on a the screen in-between the programmed
tolerances. This is used for a quick reference for the operator, or for a
more through analysis, the system automatically can assign and
dimension the intersections of the wire automatically choosing between
three algorithms. With over 20 new software additions integrated into
the system, the system is even easier to use, and program.
Generation X
Micro Machining System
Micro-Machining is a relatively newer form of machining very small
parts. Royal Master has developed the Generation X with its 5 axis of
motion and its sub-spindle making the machine’s profiling capabilities
limitless. Machining as small as .010” raw material, as large as .100”,
and lengths as short as .030”.
The Generation X uses a high speed CBN grinding wheel at 9000
sf/m and is unique to any other system that takes raw material from
a spool and automatically feeds it into the machine. This machine like
small Swiss screw machines, has a sub-spindle so when the part has
a profile or feature on both sides of the part, the machine will hand it
off, and finish machining it, thus eliminating the need for
secondary operations. This machine has the capabilities to make helix’s
on parts by controlling the rotational speed of the work spindle. The
ability also exists to stop rotation to create flats on the parts or plunge
in to make notches.
Product Line
The Generation X machine sits on the TG-12x4 platform and uses a
Linear Actuator with encoder resolution of .0001” for lengths and a
.000004” glass scale on the ram position for extremely high accuracy
on diameters.
The Generation X machine is
also Ideal for grinding Guidewires
in small to medium lot quantities.
Royal Master has taken the
regulating wheel and the work rest
blade out of the Guidewire grinding system. Using a unique system
to support the wire we have a
usable grinding wheel width of
1.5” and grinding speeds up to .75” / second. This system is
guaranteed to revolutionize the Guidewire grinding industry. There is no
need for blade sizing, regulating wheel dressing, bushing grinding, or
any of the many common tasks of Guidewire grinding in today’s world.
With this system we can either pull or push the wire through the
grinding area while maintaining complete control over the wire at all
times, never releasing it or torquing it when grinding. Full automatic
loading systems are available for either cut to length parts or grinding
off of a spool of raw material. Other applications include cam grinding,
antennae grinding Bone Screws and pins, Dental drills, etc…
Hi-Accuracy Systems
The machine’s design is based on our standard grinder line with some
very notable exceptions. The machine bed has been enlarged to add to
the stability of the system, and accommodate the new ram swiveling
feature. The ram now swivels on a pivot under the ram, moving the
entire lower ram and dresser assembly together.
This is an advantage during
thrufeed grinding that the
guides do not have to be
readjusted when you swivel.
Also the swivel is gauged by
a digital indicator, and the
adjustment is made by a
easily accessed handle. We
have also added a servo drive
regulating wheel system. The
electrical system is easily
accessed by way of a JIC electrical enclosure mounted in a space
saving position over the coolant tank. The accuracy of the system
was tested on customer applications, and the results were impressive.
We were able to achieve roundness to less than .000010”, and
straightness to less than .000010”. We are able to make size
compensations with this system in .000010” as well. The
positioning system consists of a servo driven ball screw unit and
the system’s movements are verified with a glass scale with .000004”
resolution.
Automation Systems
Cross Transfer Systems
Available in two varieties, high speed
or standard units, these stress efficiency,
and fast loading of infeed applications.
Fed from a bowl, the part will be accepted
into a shuttle head, and injected into the
grinding area. After grinding, the part will either be dropped from the
work rest blade when using the standard system, or ejected back to the
operator’s side of the machine using a “part kicker.” Depending on the
grind time, these loaders will load up to 15 parts per minute.
Magazine Loader
This type of part loader can be used
for infeed grinding or thrufeed grinding. Flexibility is realized from an
extended range of adjustments to containment guides and part movement
drive cylinders. Load the 24” long tray, or fill the 22 square inch
hopper with unground pieces. The machine will accept one part at a
time, and insert it into the wheels. After grinding, the part will drop
off of the Work Rest Blade, into a tray. Upon the start of the next
cycle, it will be swept from under the wheels, into a collection bin.
Machines in Series
Putting machines in series is an
excellent way to use your personnel to their
greatest potential. A bowl feeder into the
first roughing machine, and inline v tracks
in-between the machines make for
uninterrupted production. Make the system
complete with an air wipe and in-process
laser gage with feedback in .000010” (.00025mm) increments
to the Hi-Accuracy finishing machine.
Overhead Gantry Pick
& Place
A universal unit available in one, two or
three picking heads. Increasing the number
of heads, gives the ability to add a parts
washing, or gaging station, while still
maintaining an operator free unit.
Commonly the unit will have a walking
beam system to bring the parts into position, and exit them from
the grinder area. This unit uses a three head system for three
stations ( incoming walking beam, grinding area, and exit station).
Dual Conveyor
This unit is a great solution for Infeed
applications where quantities are low,
and different part configurations are
high. There are two conveyors on the
operator side of the machine. These
two conveyors have a timing belt used to keep the parts separated
from each other, and the separators are sized for your part diameter.
The parts will travel down the conveyor, and be placed into the loading “V”.
When the machine requires a part, it
will be indexed into the machine and
ground. When finished, it will drop off
the blade and be swept out from
beneath the wheels.
Vacuum Loader
A new loading system which is
ideal for the smallest of infeed
and thrufeed applications.
Specializing in flexibility, it will
handle multiple lengths, and
diameters from .008” (.2mm)
to .030” (.76mm) diameter
without marring the surface of the part. Interfaced into a PLC
changeovers for short or long production runs are as easy as a
few key strokes.
Vibratory Bowl System
Vibratory bowls are excellent tools to
increase efficiency of thrufeed grinding
applications. Whether you have a bowl
with a high stand for applications which are
shorter in length, and smaller in
diameter, or a bowl with an inline
feeder for your longer larger diameter
applications, you will notice an immediate
impact in your production output.
Adapt unique features such as
laser gage feedback for automatic
bowl shut-off.
