Grinding (Surface, Cylindrical, Tool & Cutter)

While placing a telescope outside the distortion of Earth's atmosphere may seem like the best way to study the cosmos, CTE Editor Alan Richter holds a different view after the Giant Magellan Telescope Organization Corp. reached out to explain how it's working with Boeing Research & Technology on an Earth-bound telescope that will minimize distortion from the atmosphere.

A shop writes to the Grinding Doc: There's lots of discussion at my company about the best diamond fluting wheel for grinding tungsten carbide. Is there a quick test to determine which wheel is best?

How do you know your coolant velocity? The Grinding Doc says the best — and perhaps most accurate — way to determine coolant exit velocity is with the Ol' Bucket & Stopwatch Technique. It'll take five minutes and tell you how close you are to wheel speed.

The updated U-Grind by Strausak AG, part of the Rollomatic group, offers an expanded 6-axis robot loader system as an option.

If you want to produce high-precision profile inserts, your tapered diamond grinding wheels need to be dressed on a regular basis. Haas opts for the profile accuracy of the XING dressing technique inside the machine.

As CTE Publications Inc. begins the 70th volume of Cutting Tool Engineering, the fundamental principles of cutting and grinding metal remain the same as when the magazine premiered with a different name to serve members of the Society of Carbide Engineers.

For the 86th episode in the Grinding Doc video series from Cutting Tool Engineering, Dr. Jeffrey Badger encourages shops to true a taper in the wheel when they perform cup wheel grinding.

GMSi Group Inc. offers the Dowell VHR-500/600 high-precision, multiple-function grinding machine with a vertical and horizontal spindle. The vertical Y-axis spindle uses a pneumatic counterweight to reduce ballscrew and servomotor loading and make movement smoother and extend machine life. The horizontal spindle uses six ball bearings for heavy grinding.

Suitable for small shops, Palmgren's 6 x 12 bench surface grinder is an economical option because it has many of the same features found on larger units. The grinder's Meehanite cast iron construction reduces vibrations while maintaining rigidity and accuracy.

Launched in November, the FCP4 High Production Drill Grinder is capable of producing a completed drill in 20 seconds, according to ANCA Inc., Wixom, Mich. Intended for tradespeople within the high-volume commodity drill market, the company said the new FCP4 High Production Drill Grinder can produce drills from 0.8mm to 4.0mm.

Watch Cutting Tool Engineering's special three-part video report that follows along as Rush Machinery in Rushville, N.Y., and Jeffrey Badger, Ph.D., a.k.a. the Grinding Doc, collaborate to establish scientific truing parameters. The report encompasses episodes 83, 84 and 85 of CTE's Grinding Doc video series.

The risk of fire from the use of cutting oil in machining operations is one of the reasons that many manufacturers avoid cutting oil.
