Grinding (Surface, Cylindrical, Tool & Cutter)

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. Jeffrey Badger routinely receives questions about grinding from shops all over the world. Through the magazine column and this video series, he provides shops with the insight and guidance they seek.

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.

Many times in making parts for aerospace engines with high temperature alloys like IN-718, Rene-95 and Waspaloy it is necessary to remove large amounts of material. Traditionally companies use, milling, turning or broaching to remove most of the material and then finish-grind to size. The engineers at Norton/Saint-Gobain's Higgins Grinding Technology Center have determined that for these materials grinding can, in many instances, remove the material more quickly and economically than turning or milling.

Whether you are grinding HSS or Tungsten Carbide, the flute grinding process is the most difficult feature to grind in round tool manufacturing. Though there are many reasons why, the main reason is that this operation is where most material is being removed from the tool, introducing the most heat and spindle load. There are several techniques that can be used to allow the grinding wheel to perform this operation more effectively.
