Grinding (Surface, Cylindrical, Tool & Cutter)

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.

Diamond dressing plates, such as sintered versions, were the innovations of yesterday. »Dia-Fliese-perfect« from Lach Diamond Inc. is today's new standard diamond dressing tool for perfect cuts, particularly in series production.

Glebar Inc. says the GT-610M is an affordable, compact, high-precision centerless infeed/through-feed grinding system, built for the machine shop. The GT-610M includes independent upper and lower slides, and a blade height ramp system for finite blade adjustment.

UNITED GRINDING has introduced a compact wheel changer for use on its WALTER HELITRONIC MINI POWER grindingnmachines and HELITRONIC DIAMOND EVOLUTION two-in-one eroding and grinding systems. The automated changer provides more setup and part processing flexibility as well as boosts overall output through continuous uninterrupted machine operation.

The first automobile internal-combustion engines used a camshaft to open and close poppet valves. Now, more than 100 years later, camshafts are still used and their basic function hasn't changed—even though camshaft geometries, materials, surface finishes and tolerances have improved greatly to achieve better fuel economy, lower emissions and larger torque.

Gleason Corp. introduces the 200GX and 260GX threaded wheel grinding machines, its latest addition to the Genesis series. The twin-spindle concept combines maximum productivity with minimum idle and setup times. Fast, easy software-guided setup of the machine allows users to set up the GX series from one workpiece to another in 20 minutes using a single tool.

Jeffrey Badger, Ph.D., , the host of Cutting Tool Engineering’s Grinding Doc Video Series, explains the difference between friable grits and tough grits in the 69th episode of Cutting Tool Engineering magazine’s Grinding Doc Video Series.

Is grinding a chip-formation process similar to turning? That's the question fielded by Dr. Jeffrey Badger, grinding consultant and author of the Ask The Grinding Doc column in Cutting Tool Engineering magazine.
