Grinding (Surface, Cylindrical, Tool & Cutter)

In the 73rd episode of Cutting Tool Engineering's Grinding Doc Video Series, consultant Dr. Jeffrey Badger discusses options for eliminating burr during grinding. Or is it even possible?

In a major enhancement to its line of grinders, Robert Bosch Tool Corp. has rolled out a lineup of small angle grinders that reportedly feature some of the highest power, greatest durability and most safety-focused options in the power tool industry.

The smartLine variant is a flexible, modular machine concept. "The secret of our smartLine range is its modular structure," points out Dr. Markus Stanik, managing director of Elb-Schliff. "We leverage a modular machine kit for the customized assembly of both surface grinding and complex profile grinding machines."

The BG series machines are equipped with a moving table or traveling column, depending on the workpiece, and are designed for grinding complex and large tools such as broaches. Depending on machine size, the components have lengths ranging from 1,000 mm at a workpiece diameter of 10-200 mm up to a maximum workpiece length of 3,000 mm and a diameter of 600 mm.

Our supplier in Asia is grinding hardened-steel parts and sending them to us for final processing. Some of them are cracking, so we're going to visit the supplier. What should we be looking for?

Titan Tool Supply Inc. announces the introduction of a line of micro diamond and borazon grinding pins designed to meet an increasing demand for extremely small, precision ID grinding. The grinding pins, starting at a 0.016" diameter, are on a carbide shank, which provides extra strength and precision.

Dr. Jeffrey Badger, Cutting Tool Engineering's "Ask the Grinding Doc" columnist, offers some simple advice for detecting whether your wheel has loading.

Dr. Jeffrey Badger explains the significance of "size effect" in the latest episode of the Grinding Doc Video Series.

For the large-scale production of flat precision components Thielenhaus Microfinish says it presents a particularly cost-efficient, compact machining solution. In close collaboration with the Japanese mechanical engineers Nissei, the ultraprecision machine tool producers offer a double-disc grinding machine characterized by four advantages: precision, cost-effectiveness, ease of use and compactness.

Episode 60 of the Grinding Doc Video Series involves a shop that was cylindrical grinding a 50mm diameter part that proved to be out of spec despite in-process gauging that showed otherwise.

Dr. Jeffrey Badger helps a shop that’s having frequent issues with wheel loading when grinding hardened steel and stainless steel.

Ask the Grinding Doc Columnist Jeffrey Badger, Ph.D., responds to a question about the difference between "constant rpm" and "constant metal-removal rate" when it comes to grinding cams.
