MTB Introduces Revolutionary New Gear Hobbing Machines at MPT Expo

Machine Tool Builders will unveil, for the first time in North America, the new HAMAI N70 Horizontal Hobbing Machine, and SMG’s SH410 Vertical Hobbing Machine, both delivering long-sought performance and exceptional value.

LOVES PARK, IL – September 15, 2023 – Machine Tool Builders Inc., with its fast- expanding lines of worldclass new gear production machines, combined with its renowned rebuild/recontrol services for older machines, now offers gear producers the optimum solutions for the widest range of applications. Examples of these many technologies will be on display at the MTB exhibit at M+PT Expo, Booth #3206. Visitors will have the opportunity to experience the many benefits of these new solutions, including:

  • The HAMAI N70, which takes CNC horizontal hobbing to ‘the Nth Degree’. The N70 is the latest in the HAMAI series, a highly respected Japanese global brand with thousands of installations worldwide. With the N70, HAMAI has made a quantum leap forward for more economical, more dependable production of high precision aerospace and automotive gears up to 70 mm in diameter, and shaft lengths to 250 mm. The N70 has been completely re-designed to pack more power and precision into a very compact package, with extreme rigidity and the capacity for gears up to Module 2.5. Most importantly, it’s available fully automated to reduce non-productive load/unload time to just three seconds. Equipped with the latest FANUC controls, touchscreen and HAMAI’s operator-friendly programming, the N70 is also exceptionally easy for even less experienced operators to run day in, day out.
  • The SMG SH410 Vertical Hobbing Machine, for parts as large as 410 mm in diameter, and workpieces to Module 8. It’s an exceptional solution to meet the day to day demands and flexibility requirements of today’s gear jobbers. The machine combines high hobbing and table speeds and rapid X- and Z-axis travel, with the high rigidity, high torque, high precision worktable and powerful workspindle to cut cycle times while delivering high precision gear cutting even at high cutting loads. This productivity is coupled with a variety of options with the gear jobber in mind: various automation configurations; on-board chamfering/deburring; provisions for extra-long shafts to 650 mm; even hard skiving. It’s compact, highly rigid, ideal for both wet or dry hobbing, and available with FANUC or Siemens CNC with easy, user-friendly dialogue programming.
  • MTB’s comprehensive new recontrol/retrofit package for larger-capacity profile grinding gear machines with outdated controls, adding highly desirable performance at a fraction of the cost for new machinery.

The package is built on state-of-the-art Fanuc or Siemens CNC platforms and includes MTB’s user-friendly Human Machine Interface (HMI) with Profile and Worm Conversational Software designed to simplify the operator’s programming, setup and operational tasks, and help reduce costly non-productive time as well as the risk of operator error.

In addition, the MTB package includes provisions for advanced, fast and flexible on-board wheel dressing, as well as optional on-board inspection featuring the latest Marposs or Renishaw 3D scanning probe technology (depending upon the machine, control choice and application).  The package includes all required mechanical and electrical components – standardized, up-to-date and easily replaceable to help avoid early obsolescence.

“With the rate of today’s controls obsolescence increasing and the longevity of the physical machine tools today, upgrading your controls platform becomes important to remain competitive,” says MTB’s Ken Flowers.  “This new recontrol/retrofit program is the best way for companies to extend the productive life of their older machines for years to come, take their performance to levels expected today, and at the same time save tremendously versus the cost of new equipment.”

The MTB recontrols/retrofit program is available for all major gear grinding machine makes and models, in size ranges 400 mm and above, and can be performed at the customer’s facility or at MTB, depending on the customer’s location, requirements and machine size.
