Grinding (Surface, Cylindrical, Tool & Cutter)

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.

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.
