to buy a Studer grinder?
All machines in the market are not equal. How to test a
Ways -Foremost is the ways. The machine made in the last
15 years have a type of plastic poured which keeps the
oil on the ways. If they are worn out, it takes 320,000
USD to fix them. The machine is pretty much not worth
anything. Also find out how much is the wear so that you
know the life of the machine at the highest level.
Granitan Cracks- Make sure there was no crash and the
base is not broken anywhere. Though I have personally
repaired a few cracks, some of them the cost 320,000
to repair. It has to go to Switzerland for repair.
B axis -There are a few machines which were made without
a curvic coupling and is never going to accurate. The
price of a new B axis is about 40,000. So make sure you
have the proper B axis.
Scales - Make sure your scales are enabled. The machine
can have a ton of back lash. People can turn the scales
off and sell it to you. It will not have the same
accuracy. Cost could be 15,000 Per axis.
Check the backlash on all the axes. Cost could be
15,000 per axis
Check the play on the work head bearings. Cost could be
as high as 25,000.
Wheel head - Check the spindle play. Cost could be
Tail stock - Check the play - Cost could be 8,000
Electronics , though it is easy to replace, make sure
you know what you are getting into. Some components are
Communicator - Make sure it works - Cost could be 18,000
Sensitron - Make sure it works - Cost could be 8,000
Gauging - If you are going to use it test it and make
sure it is not obsolete. Call the gauge maker and give
the model number. They are ultra expensive to change.
Could be 25,000.
Monitor- Make sure it is good enough - Cost could be
Coolant tank - Make sure it is the right tank - Cost
could be 8,000
Id Spindle - Run it for full speed. Make sure oil drips
from the front. Coolant lines are not clogged.- Cost
could be 22,000.
Cables and hoses - Sometime the type of coolant can eat
it so bad, machine becomes un reliable. The fixing cost
could be 20,000.
Carbide - Depending on what was run on the machine the
corrosion could be really bad. I have seen in occasion
customer has rebuilt the whole machine after 12 years.
Also watch out for machines which comes out of auction.
Some have sit in water for a while. Make sure you find
out who owned the machine last. When was the last time
it ran good parts. You might see some machines sitting
on the market for a long time. There is always a reason
The cheapest CNC Studer is 300K. This is entry level
Luxury. Mid level machine like a S33 with OD and
ID feature could be 700K. S31 well appointed could run
you into 1 million. S40 well appointed to 1.3 million.
Fully loaded into 1.6 million. Options are plenty.
Different work heads, center line height, quickset, non
round grinding, Thread grinding and many more can tip
the price by 100K. Getting any used Studer is a bargain.
