Machining

Take a Gemba walk. If you're not familiar with what a Gemba walk is, let me fill you in.

Many trends affect the metalworking industry, including customer demands for the best quality, lowest cost and shortest delivery time. Design concepts for modular machine tools can address these expectations through general-function modules that can be combined to meet job requirements while reducing costs and lead times.

Time for a literature review.

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.

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.

What possesses a new job shop to buy a $1 million, twin-spindle machining center when even the smallest purchases are subject to debate? At Jersey Elite Manufacturing (JEM), Rockaway, N.J., the answer is experience and detailed analysis, because sometimes a seemingly extravagant investment is the smartest move.

Offline presetting maximizes machine availability, reduces scrap.

Milling metals hardened to 52 HRC and harder with solid-carbide cutters doesn't require a heavy-duty, high-performance machine tool when a machinist employs trochoidal milling and applies cutting tools with an appropriate substrate, coating and geometries. (With Video.)

Dr. Jeffrey Badger, the host of Cutting Tool Engineering's Grinding Doc Video Series, offers his take on the effectiveness of scrubber nozzles. nAbout 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.

Walter says it has enhanced its M4000 milling cutter system with a new slot drill and a T-slot cutter, enabling users to tackle the vast majority of typical machining operations with a single high-performance yet cost-effective tooling system.
