The EDFH-1 can handle a work- piece up to 50 kg on its 350 × 250- mm table. The machine moves 220, 180, 300 and 220 mm on its X, Y, Z and W axes, respectively. For manufacturers who need a sinker EDM that can handle larger parts and/or make larger start holes, Makino offers the EDAF-Series ma- chine platform. The EDAF2 provides XYZ travels of 350 × 250 × 250 mm and workpiece weight up to 500 kg, while the EDAF3 provides 450 × 350 × 350-mm travels and supports up to an 800-kg workpiece. “All of these machines are built for automation due to their software, in- novative mechanical design, and high level of predictability and submicron repeatability,” Bradford said.


Taper-Free Cutting Omax entered the world of abra- sive waterjet micromachining with its MicroMAX JetMachining Center, which promises taper-free cutting on a wide variety of materials. This versatility en- ables medical manufacturers to use abrasive waterjet cutting to make surgical clamps, orthopedic/prosthetic components, gears for electromechanical medical devices, and parts for laparoscopic tools. The MicroMAX is the result of the commercialization of


For ultra-precision machining and the surface finish capability of small/fine wire operations, Makino offers the UPN-01 wire EDM.


micro abrasive-waterjet technology developed under the support of a National Science Foundation Small Business Innovation Research Phase II grant. MicroMAX comes equipped with a high-precision 7/15 Mini MaxJet5i nozzle with an 0.018-mm orifice and a 0.38- mm mixing tube, and is capable of cutting a kerf as small as 0.38 mm. The same nozzle body is available in a 5/10 beta version to cut thinner materials for spinal cages, for example, with a 0.13-mm orifice and a 0.25-mm mixing tube. Omax is using an NSF SBIR Phase IIB Supplement to further downsize the nozzle and to incorporate 3D machining capability. In addition, Omax is modifying its award-winning Tilt-A-Jet cutting head to mount it on the MicroMAX. The Tilt- A-Jet will be available as an option, which will minimize the taper of parts up to 40-mm thick. The machine also has Omax’s advanced pressure controls


for piercing delicate materials, minimizing the probability of delamination or cracking inside a blind hole. “One of the problems with conventional waterjet is pierc- ing delicate materials like laminates, composites or glass,” said Liu. “When you try to pierce with the waterjet, before it breaks through the material the jet decelerates, stops, and reverses its direction at the bottom of the blind hole. “A large stagnating pressure develops inside the blind hole,


and piercing-related damage results when the stagnating pres- sure exceeds the tensile/adhesive strength of the materials.” The new waterjet machining center can also precisely cut stainless steel, titanium, nitinol, graphite, copper, and more, Liu said. In addition, laboratory testing using the Micro- MAX to cut fiber-reinforced PEEK showed the fibers are cut cleanly, he said. The MicroMAX’s table is 0.71 × 0.71 m (28 × 28") square, and has an XY cutting range of 0.61 m. It uses high-precision linear encoders, vibration isolation and intuitive software control systems for position repeatability of 2.5 µm and a positioning accuracy of about 15 µm.
