The Walter Helitronic Micro combines a new design with linear motors to achieve 30 percent faster speeds and as much as 50 percent better surface finishes than machines with conventional ball-lead screws, the company says.

The CT450L is one of the latest models in Studer’s line of affordable ID grinding solutions, the company says.

 The Studer S33 from United Grinding delivers universal CNC grinding for complex workpiece geometries.

 Available from United Grinding, the Helitronic Power ECO-Loader Plus auto-loads as many as 165 tools in one setup while occupying minimal floor space. Also available is Tool Studio software, which can handle geometries including variable helixes on a step tool as well as both concave and convex cam-relieved forms. 

Profile grinder manufacturer Blohm Jung's GEOID system automatically compensates for wear in diamond dressing tools. By removing variables that require operator attention, the system is said to ease wheel dressing, ensure accurate profiles and extend the service life of dressing tools.  

Studer’s S33 universal cylindrical grinding machine said to provide low cost per part during external and internal cylindrical grinding of small and medium-sized workpieces in a single clamping. The machine is designed for both single-part and large-series production runs and is suited for toolmakers in job shops and manufacturers.

Combining different machining processes on the same platform has been a major theme in machine tool design for two decades or so. The Studer S242 combines cylindrical grinding and hard turning. A look at this machine shows that both of these machining processes benefit when they share the same platform.

Machine tool automation, particularly grinding machine automation, offers various returns on investment. Different shops notice different advantages, and sometimes shops overlook important benefits when they are deciding whether to automate.

Moving on oil can let a grinding machine deliver more power along a smoother pass.

Curt Reed uses advanced grinding techniques in the pursuit of short-run, sub-micron work that other shops can’t perform or won’t attempt. His shop’s commitment to its customers is reflected in the high level of equipment sophistication and applied grinding acumen.

In a cycle that is 90 percent grinding and 10 percent more basic metal cutting, letting the grinder perform the last 10 percent may make sense.

JPL’s Space Instrument Shop does this routinely, but it takes some special equipment and some unusual procedures. Above all, it takes patience.

A grinding technique akin to high speed machining offers an alternate method for grinding nickel-alloy blades and vanes used in turbine engines.

Following a sustained period of growth, 600 Group subsidiary Gamet Bearings has invested in a new grinding cell to increase capacity, improve bearing accuracy, reduce costs and improve both process consistency and customer satisfaction.

Earlier this year, visited a cross section of metalworking manufacturing companies in Switzerland to find out how they are meeting the challenge of globally competitive manufacturing.

A grinding machine is not a machining center, but it can sometimes take on milling and drilling (or even turning) to make the overall process more efficient.

This Cleveland grinding shop owner discusses the challenges and rewards of starting a business in downtimes, and what it takes to stay competitive.

Custom automatic loading systems for grinding machines often lack the flexibility to allow quick job change-overs. These off-the-shelf loading systems were designed with intuitive set up in mind.  

The domestic die/mold industry is today going through considerable change-a good deal of which is being driven by an urgency to become more competitive coupled with advances in technology. Here's how one shop combines skill and technology to be more than just competitive, but to excel and grow.

When Absolute Grinding shifted gears to CNC machining, the company saved a significant amount of time. The new machines were capable of performing many tasks simultaneously, making the shop more efficient.

If one must pick a manufacturing specialty, grinding carbide might not be the first choice because it’s perceived to be very difficult. RPM Carbide Die, however, has worked the material for nearly 40 years and, as specializing seems increasingly to be the order of the day, this northern Ohio shop is in a good position to thrive.

This manufacturer now applies hybridization to the task of machining complex parts that require flexible grinding configurations. In addition to ordinary face grinding, for example, these machines also have the capability to grind bores, diameters and tapers.

Find out how these grinding centers helped this major aerospace supplier become more efficient and reduce waste.

By adding a CNC OD/ID grinder, this California gear manufacturer brought a lot of farmed-out work in house, improved quality, slashed lead times—and saved money.

It sounds like a contradiction in terms-between centers and centerless grinding on one machine. But for some categories of workpieces, it's a viable production process that can yield machining time reductions of 45 percent over separate grinding operations.

Of all the metalworking processes, grinding is probably the most application specific. In a job shop environment, however, flexibility is the key to successful grinding. Here's a look at how one captive job shop successfully transitioned from manual to CNC grinding while standardizing its grinding process parameters to accommodate the demands of low volume, high mix production requirements.

Jeff and Gary Caron of Caron Precision, Inc. know grinding. They know grinding so well that their business is strictly grinding--no other machining at all. But not even the Carons ever thought they would invest in a cylindrical grinding machine to facilitate a single application.
