Designed to produce the ultimate in precision with a stationary table design and the highest construction specifications
The UPV-3 Wire EDM machine was designed to produce the ultimate in precision machining while achieving ultra-fine surface finishes.  The machine is built on the proven Makino Uj-Series Wire EDM platform that utilizes a stationary table design, and is held to an even higher construction accuracy specification.  The UPV-3 uses an oil-based dielectric system, which provides the capability to produce surface finishes down to 0.02µmRa (1µinRa), which is considerably finer than traditional water-based Wire EDMing.

The use of di-electric oil on the UPV-3 machine, which is the same di-electric oil used by Sinker EDM, allows for a smaller discharge spark gap (i.e., the gap between the wire electrode and the workpiece at the time of electrical discharge) than traditional deionized water di-electric can support.  Unlike deionized water which will always be slightly conductive, di-electric oil is electrically neutral and will support machining with much lower power levels to achieve greater precision, higher-level surface finish, and improved metallurgical quality.

There are additional secondary benefits with the use of an oil di-electric fluid that help to improve work piece quality.  The lower power levels help to produce lower levels of HAZ and Recast to a point to where they are virtually undetectable.  Unlike deionized water, the oil di-electric fluid is chemically neutral, so it completely eliminates oxidation, meaning that  steel work pieces will never rust while in the machine.  Oil also protects synthetic materials such as carbide and PCD diamond, and eliminates the oxidation corrosion of these materials binder composition, such as cobalt depletion of carbide, and preserves the material integrity to provide dramatic increases in component functional life.

Operational access to the work zone is excellent with the 3-sided rise and fall work tank design, as this simplifies loading and setup of the work piece while also minimizes automation requirements.   User-friendliness and productivity are hallmarks of the UPV-3 machine with the Hyper i control system. The modern high definition wide 24” class touch screen utilizes Pinch/Swipe/Drag operation similar to smartphones that make operation extremely easy and straightforward.  The Hyper-i control also features a standard advanced Handbox, on-board electronic manuals, advanced E-Tech Doctor function, and video training tutorials that empower the operator with everything they need to be productive right at their fingertips.

The UPV-3 is an ideal machine for ultra-precision applications such as precision stamping and fine-blanking components, and can be equipped with an optional integrated 3D Setup Probe and Rotary Table, which are ideal for Cutting Tool Insert manufacturing. The UPV-3 is also standard with safety equipment such as an integrated Fire Suppression system for reliable extended unattended operation.
