InternalS121 Universal Grinding Machine

With regular new developments every 6 months, Fritz Studer AG says it has surprised users of internal cylindrical grinding machines in the last 2 years. What still appeared as a separate machine with the S141 universal machine (component length up to 1,300 mm) in May 2014 has evolved into a complete machine platform with the universal machines in the S141 and S151 series in autumn 2014, the S131 universal machine and the S122 production machine in spring 2015 as well as the S121 universal machine in autumn 2015.

QUICKPOINT Grinding Machine

The Junker Group says its ingenuity and expertise are put on display with the flexible, high-performance QUICKPOINT grinding machine. High-speed grinding combines Junker precision with maximum flexibility.

Cranfield Precision TTG Machine

Fives says the new Cranfield Precision TTG machine is a radically new concept. While conventional machine tool platforms use stacked linear axes as the primary motion control system, the Cranfield Precision range coordinates two rotary axes and a short linear axis in a "twin-turret" design.

EWAG Laser Line Precision Grinder

Deemed the most compact laser production center in diamond tool manufacturing, the new EWAG LASER LINE PRECISION serves as an alternative to conventional grinding and eroding methods that are unable to handle the level of precision required for processing complex cutting contours and narrow tool tolerances in CBN, PCD and CVD-D materials.

Gemini NGM and Sirius NGS Tool Grinding Machines

J. Schneeberger Machinen AG offers two new grinding machines: the Gemini NGM (pictured) and the Sirius NGS. With both machines, space requirement was give special attention to achieve smallest footprint with a large work envelope.

Product focus: GrindSmart Nano6

As part of its occasional product focus video series, Cutting Tool Engineering Plus presents a closer look at the GrindSmart Nano6 from Rollomatic SA.

Tech swap

Part of CTE's October cover story, this video sidebar follows tool grinder Jim Clark as he employs the ANCA CNC toolgrinding machine at Hamill Manufacturing to create custom geometry onan endmill for a military application.

Multitasking video

A Studer brand S242 machine, which combines hard milling and grinding, is shown hard milling a toolholder without coolant, then grinding the holder's taper with coolant to achieve the required surface finish. This video is a supplement to the January 2010 Cutting Tool Engineering feature—"Finish Line"—about finishing hardened workpieces on multitasking machines.

Revolution in Centerless Grinding

Ryan Michels, a sales manager with Tru Tech Systems, Mt. Clemens, Mich., discussed centerless grinding during his Fast Track Seminar hosted at the Cutting Tool Engineering booth during IMTS 2010.
