FLEXIBLE PRODUCTION NEEDS

As a company that designs, manufactures and services a high number of bespoke cutting tools, set-up times are
critical for Hunter Precision. Here, the VPulse 500 demonstrates how innovations from VOLLMER are making a huge
difference for the end user. One new introduction of the VPulse 500 is the contour edge measuring system that will
follow the contour of the tool to collect more measurement points – faster than ever before. Ron indicated, “Quality
and set-up times are very important to our business, and with the new probing system, we can probe our tools at
least 50% faster than before. By doing this in a fraction of the time, we can collect more measurement points. This
reduces potential quality issues, especially where there are variations in cutting edges due to the brazing process.
The probing cycle will identify and rectify this instantly.”

The probing system works harmoniously with the CNC control panel and the intelligent ExProg programming
system. This incorporates a user-friendly navigation menu to enable quick and easy acquisition of key machine and
program parameters. One new feature is the ability to record, review and analyse documentation. As Ron stated,
“The control panel has a user-friendly layout and the Exprog software is very intuitive. We can add notes to tool
programs regarding machine set-ups or other factors that our operators may need for the next time they are working
on the same tool. Previously, we had to take notes and store them in our ERP system, now this critical information is
at hand for every repeat or regrind tool we produce. This signifi cantly cuts down set-up times for the shop fl oor.”

The advancements in the ExProg software suite enable individual data to be assigned to each contour element of
the tool and profi les can be divided into part contours to deliver even greater fl exibility. Ron further stated, “The
software is very advanced, and it gives us feedback on a wide range of parameters. This gives us greater visibility
of processing times, power consumption and any processing deviations. Even the simulation suite is contributing
to our set-up time reductions as it simulates everything from the tool holder to the wire and the jaws – ensuring we

never get a collision. Overall, we have been delighted with the machine. Its productivity, quality and technical
advancements have been a huge benefi t to our business. One thing that is not always a given is service – but
VOLLMER of America excels here too. The service and support from VOLLMER of America has been excellent.”
