5 axis, max work envelope a 8 inch cube,but able go real small parts and maintain the accuracy in measurement and true position.

My understanding is that the oiltech machine is primarily for cutting carbide, and generally cuts slower than a "normal" (water) machine..
Hi guys, i just came back from AgieCharmilles and thought I'd share some info and pics. this is the Cut 1000 oiltec and it is true slightly slower main but faster trims to make up the time. Of course if you are buying it to be a band saw and only do 1 cut stuff you have way to much money! lol The latest is IVU. it has an optical measuring system built in and can inspect your part before coming off the machine. if it is out of tolerance, it will recut automatically. Don't know what it does if cavity is to big but knowing the guys in Europe they will come up with something.View attachment 79681View attachment 79682
It felt that now was a good time to step in and discuss the capabilities of Makino's UPJ-2 and the newer UPN-01 WEDM machines. Both models represent a paradigm shift and technological leap forward for small wire EDM operation by utilizing a horizontal Wire EDM design that is well suited for production micro-machining applications. The key concept with the horizontal configuration is to have gravity help you rather than hurt you when processing small parts and/or small slugs. All geometry lead-ins should be at the 12 o'clock position, so that when the slug is finally cut away, it falls away from the wire, preventing the wire from being pinched or breaking. This becomes increasingly more important as the wire diameter size gets smaller. Another big advantage to the horizontal configuration it that it also allows you to extract and remove slugs automatically and unattended.
The machines use flushing pressure and also a small probe for ejecting the slug. Since there is no conventional work table (parts are held in System 3R or EROWA fixtures), slugs can be ejected and allowed to fall to the bottom of the work tank. The horizontal design actually retains the slug in-place in the work piece material until the slug ejection function is performed. This eliminates the high potential of machine crashes or dropping of the small parts or slugs into the lower head or nozzle that occurs on traditional vertical WEDM platforms.
The machines horizontal configuration does away with the conventional water jet threading system and replaces it with an ultra-reliable air injection and suction system for threading. Using 20um (0.00078") diameter wire, the machine can thread a 30um (0.0012") diameter hole with 100% reliability! The UPN-01 is also capable of operating with 15um (0.00059") diameter wire. Both machines use oil di-electric to provide higher accuracy and finer surface finish capabilities. Reasons for the switch to oil are that Oil is a true insulator, whereas Water will always be slightly conductive. This gives Oil an accuracy advantage due to the ability of the di-electric medium allowing for more precise control of the machining spark gap, and this is a key critical item for the ultra-low discharge power levels used during the final finishing passes.
To further improve machining accuracy, the UPN-01 uses a special linear motor and air slide bearing system (like a CMM). This VERY unique motion control system was designed to overcome movement friction and inertia, and provides the smallest possible movement increment. This configuration produces machining accuracy and repeatability is in the sub-micron range. As part of maintaining this level of accuracy, the machines also have their own Thermal Chamber, wherein the machine creates and controls the temperature environment inside the machine (the work tank environment has its own temperature control air conditioning system).
I have added a couple of pictures too to help illustrate the machine and the slug ejection system. Thanks for reading!!!
