IMTS PAVILION: METALCUTTING


All the new and advanced machining and automation systems in the Mazak IMTS booth will be under power and running real-world part demonstrations. For example, Mazak will unveil its new Variaxis i-800T multitasking machine and demonstrate it cutting an aerospace jet engine blisk using 5ME’s cryogenic cooling system. Other applications experts from Mazak’s Value Inspired Partners (VIP) program will be on hand to discuss and demonstrate total manufacturing solu- tions and part-processing improvements.


Mitsui Seiki Strategy Based on High-Precision Machining Mitsui Seiki USA Inc. (Franklin Lakes, NJ) will exhibit three machines that demonstrate its ability to provide high-precision technology that meets the most exacting machining standards for aerospace. “All three machines are our Vertex-style ma- chines that machine a decimal point tighter,” said Scott Walker. “One machine will have a direct drive [DD] motor machine that is capable of grinding like a jig grinder in addition to precision milling capability. The second machine will be a single-blade Vertex milling machine aimed at the Ti-Aluminide market, and the third will be the new Vertex 55X-H additive/subtractive ma- chine with a powder metal feeder and a laser assembly head with shield gas being demonstrated machining a damaged jet engine blade in need of repair.” The Vertex 55X-H, which is making its debut at IMTS, is built on a precision Mitsui Seiki VMC platform with a spindle- adapted laser DED (Direct Energy Deposition) / powder feed nozzle. The nozzle loads into the toolchanger like any conven- tional tool and is changed automatically via the CNC program prompts. For milling the 3D-printed surface or internal feature, a milling/drilling tool replaces it and aspects of the work- piece are machined conventionally. The process is under full adaptive control as the part is made, moving back and forth between additive and subtractive while maintaining common center line integrity to produce the intended surface or feature with sub 15-µm accuracy within the work envelope. Users can choose either a CAT or HSK 15,000–30,000-rpm spindle. “The Vertex 55X-H hybrid machine is well-suited for the repair of a number of different types of airfoil parts, such as high- pressure turbine and compressor blades, low pressure blades, blisks/IBRs and impellers for the aerospace, power generation, and oil and gas industries,” said Walker. ”


Hurco Invites Visitors to Race to Profitability Indy-500 Style Hurco will capture the spirit of Indianapolis, the headquar- ters location of the company since its founding in 1968, and

the home to the single largest one-day sporting event, the In- dianapolis 500. Visitors will be able to race RC IndyCars on a Hurco created scaled-down version of the Indianapolis Motor Speedway, complete with a blimp and leaderboard. Attend- ees can check www.hurco.com/imts to see what hours open racing will take place and/or to register for a spot to race competitively. Prizes will also be announced on the website. “In addition to sponsoring IndyCar team Ed Carpenter Racing [ECR] with drivers Ed Carpenter and Josef New- garden, the team uses our CNC machines at their machine shop,” said Maggie Smith, marketing manager. “Since we know that both racing and machining rely on speed, power, and precision to succeed, we thought the race to profitability theme would be a fun way to showcase how Hurco CNC machines make our customers more profitable,” said Smith. Hurco will exhibit several new models of CNC machines in addition to their newest technology invention that will enable owners of Hurco vertical machining centers to transform their WinMax part programs to a 3D-printed rapid prototype directly on their CNC machine using an optional spindle- powered wireless accessory. The 3D print head adapter, which extrudes plastic PLA filament, will be exhibited at the Hurco booth and at the Additive Conference.


Turned Parts Complete in One Clamping “Machining parts complete in one clamping from bar stock or castings is still the primary strength of much of today’s turning-based machining,” said Jeffrey Reinert, president and CEO, Index Corp. (Noblesville, IN). “Our technology enables manufacturers to drop precision parts complete in one setup, run untended, get more machin- ing hours out of the week, 24/7, if they so desire, and be competitive globally. And that’s where our advanced technol- ogy for US-based companies comes into play with products like our new extended version of the Index MS16 Plus.” The six-spindle CNC lathe simultaneously accomplishes two or more operations, dropping complete parts in very short cycles. The machine features six independent liquid-cooled, hollow-shaft CNC spindle drives each capable of 7000 rpm, a main spindle drive with increased stiffness, and hydro- static guide bushings on each carrier slide, which eliminate wear and transmission of vibration to the tool. “With liquid cooling, spindle and drum cooling is accomplished away from the work area, making the machine more stable, able to run at higher rpm, with more torque, if needed, according to the needs of the material being cut,” said Reinert.
