All machines in the market are not equal. How to test a Studer? 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 420,000 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 420,000 to repair. It has to go to Switzerland for repair. Here is some cost for you. 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 15,000 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 obsolete. 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. Cost could be 25,000. Monitor- Make sure it is good enough - Cost could be 4,000 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 come 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 for that. 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. S41 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.
