Up for sale is this 1997 Makino KE-55 CNC knee mill. This machine is in good condition and functions as it should. I have been through this machine cleaning and performing regular preventative maintenance. The oiling system has been flushed and filled, ball screws greased, belts tensioned, & machine cleaned. This unit does have the factory coolant tank and sump it is just not pictured. This is a Fanuc Professional Jn which is a 20FA controller and works great. The spindle is a 4000 RPM unit and is very smooth. This can do rigid tapping as well as helical interpolation. This mill is unique in that you can use it as a conventional machine with the hand wheels on the front or you can use the built in conversational programming in addition to loading a full CNC program. The conversational is very user friendly and handles angle milling, pockets, radius, bolt hole patterns, & more. Hardly any training is required to use it. This machine is capable of DNC (drip cnc) through the RS232 port on the control cabinet.
This mill weighs 6600 pounds and has a very stout cast iron base for maximum rigidity. All the slides are of the box way design are ground and hardened with the ways being hand scraped Turcite. Everything is automatically lubricated with a Showa oil pump. The machine is built with oversized and tensioned ball screws to prevent the effects of thermal growth. The T-slotted table is in great condition with no drill or mill marks on it.
I have all the original manuals (large stack) and even the original inspection report for this machine when it was shipped. This is a very high quality milling machine that doesn’t come up for sale often. These were very expensive when new and so they are not very common to find.
