MAKINO INTRODUCES G5 GRINDER
Makino Introduces G5 Grinder
Grind, drill, bore and mill all on the same machine
MASONOH -- January 2007 -- Today’s capital equipment must be more flexible and capable than ever.
With this in mind, Makino has introduced the G5 Grinder horizontal machining
center, capable of grinding, drilling, boring and milling all on the same
machine.
“The
biggest advantage of a machine like the G5 is the ability to eliminate non
value-added time in the manufacturing process,” said Tim Jones, product manager
of horizontal machining centers at Makino. “Because you can go from milling to
grinding in one machine, you’re not only saving on capital equipment but you’re
also able to keep the part in the machine, eliminating all the out-of-cut time
that does nothing but add to your costs and lead time.”
Using a
single machine to grind and mill helps to eliminate setups, work in process,
stack up errors due to multiple setups, reduces fixture costs with 5-axis
capability, and simplifies the manufacturing process with NC controlled
intermittent dress.
The G5
The G5 is a
full 5-axis machine, with a B-axis of .5/1.5 sec (90/180), a C-axis at 100 rpm,
a 60-tool automatic tool changer that will hold up to a 8.7 inch (220mm)
diameter grinding wheel.
A unique
two-axis coolant nozzle allows the G5 to accommodate variations in wheel
diameter and changes in cutting direction while maintaining ideal cutting
conditions. It also allows for intermittent rotary dressing, an NC controlled,
hydraulically powered feature that redresses the wheel to reestablish profile
geometry on the cutting wheel.
For added
reliability, the G5 features one-piece X , Y and Z -covers, proven 1-Series
tool changing systems, and 10 micron cyclonic secondary filtration.
Thermal
growth and stability are areas which Makino pays special attention because high
speed machining and hard milling are techniques many shops are implementing to
cut down on lead times and costs.
Features
that allow the machine to be thermally stable include an integral spindle with
the cooling jacket linked to the bed temperature for part consistency, a
coolant chiller to maintain high precision machining, core-cooled ball screws
in all axes, and the use of high volume high pressure coolant. Coolant is
applied to the grinding process at the ideal orientation to achieve better
cooling than traditional grinding processes. These and other features
achieve superior part consistency.
As far as
stability is concerned, the stepped column machine construction provides
optimum rigidity and speed, with close proximity of the ball screw to the
column center of gravity, large LM guides, reduced column weight, and dual
supported pre-tensioned ball screws. Also, the NC rotary table has a large
diameter bearing surface, assuring rigidity.
