Grinding Machines

Pinch grinding offers highest concentricity particularly on long and thin parts. The rough and finish grinding are performed in one pass. This innovative way to grind roughing and finishing simultaneously eliminates a separate process and reduces cycle time. The machine utilizes two different grinding wheels running on separate spindles and positioned on independently- controlled CNC linear slides.

With five axes of motion and storage for 40 tools, the machine can grind thread grooves and also machine the nut circumference, end surface, key grooves, and return tube holes in a single setup. In addition to producing large savings in manufacturing time, elimination of setup changeovers also assures exact phase alignment of thread grooves and return tube holes. A standard touch probe enables automatic pre-processing phase alignment of the thread groove and wheel.

Glebar’s automatic dresser is available with manual or motorized quill advancement. With motorized quill advancement, it is possible to have a canned dress cycle. Operators can preprogram the frequency of the dress to run after a set number of cycles or time. This allows them to run multiple machines at once increasing their efficiency.

Boring bar grinding on the Rollomatic 6-axis tool grinding machines offers exceptional flexibility in comparison to conventional single-puropose grinders. With its 6 fully interpolating CNC axes and 6-station wheel/nozzle changer, the machine can easily be adapted for individual boring bar designs, both for short and long runs.

SintoGrind HSS-X 1400 is suitable for flute-, thread-, profile-, internal and external cylindrical  grinding of steel materials such as HSS, PM and medical steels. SintoGrind HSS-X 1400 is low foaming, prevents surface burning, inhibits burr development, is low misting and offers excellent filterability. 

The ShapeSmart®NP50 is a 5-axis Precision Cylindrical Pinch/Peel grinding machine with integrated 3-axis robot loader and grinding diameter range from 0.025 – 25 mm (.001"– 1").

the GT-610 EZ has the ability to produce G-ratios that can exceed those of machines twice its size. When running super abrasives, a variable frequency drive on the work wheel spindle is available to increase wheel surface feet.

Developed especially for the re-sharpening and production of rotationally symmetrical PCD tools, the Walter Helitronic Raptor Diamond is particularly well-suited for shops that do not require features such as automatic tool support systems or automatic grinding wheel/electrode changers, but still need a high degree of flexibility in the working area for diverse types of tools. This ensures that manufacturers have access to Walter quality with exactly the features they need for part-production and re-sharpening success.

The new Walter Helitronic Raptor from United Grinding Group is a flexible, cost-effective tool grinding machine. Created for the grinding and re-sharpening of rotationally symmetrical tools for the metal and wood industries, the new Helitronic Raptor offers both automation-ready flexibility and an economical, universal design.

Glebar Co. delivered a solution for grinding deodorant balls while reducing cycle times and improving throughput. Glebar developed ball grinding for the golf ball industry in the 1960s using centerless grinding fundamentals. The process was adapted to grind deodorant balls and other spherical or cylindrically shaped components. Glebar machines can grind most hard-to-turn materials such as carbon fiber, fiberglass and polypropylene.
