Grinding (Surface, Cylindrical, Tool & Cutter)

A shop creep-feed grinding hardened steel using a water-based coolant kept running into trouble after grinding for a few hours. Everything would be grinding along fine, but then—WHAM—really bad burn would bring the job to a halt. And the burn wouldn't go away until the shop dressed the wheel again.

Samputensili offers a ground-breaking concept that totally eliminates the need for cutting oils during the grinding of gears after heat treatment. The new machine, which is called SG 160 SKY GRIND, features two spindles: one for skive hobbing and one for generating grinding.

Meister Abrasives USA Inc. in December 2015 added an advanced CNC manufacturing system to its lineup, making it possible for the North Kingstown, R.I., company to manufacture large diameter external wheels in the United States using equipment, materials and a manufacturing process identical to those used by its parent corporation in Switzerland.

Productive Times challenge: Effectively clean and cool grinding oil applied in latest-generation grinders. The solution: A filtration and chiller system that directly communicates with grinding machines.

Jeffrey Badger, Ph.D., fields a question from a shop getting "terrible burn on the shoulder" when cylindrical grinding steel parts with a straight plunge.

The opening of the new facility included a traditional Japanese Kagami-Biraki ceremony, where a barrel of sake is broken open with wooden mallets. Several customers, dealership representatives, city officials, Shigiya employees and other invited guests were present for the event.

Episode 64 of the Grinding Doc video series: When pushed to use a tri-grit wheel to cup-wheel grind tungsten carbide sawblade teeth, a shop turned to the Grinding Doc for some guidance. About the Grinding Doc Video Series: Thanks to his work as an independent grinding consultant and the author of the "Ask the Grinding Doc" column in Cutting Tool Engineering magazine, Dr.

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.

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.

The Look Ahead department in the October issue of Cutting Tool Engineering features a high-speed spindle that reduces natural vibrations.

Companies that make cylindrical cutting tools from PCD and other materials face two key challenges: meeting the surging demand for PCD tools while retaining the ability to produce HSS, carbide, ceramic and cermet tools, observes the Machine Technology column in the October issue of Cutting Tool Engineering magazine.
