So their TTG machine platform-which lends itself to multiple machine configurations and processes, including OD grinding, ID grinding
, profile grinding, milling, polishing, hard turning, and metrology-is non-conventional.
is an alternative for finishing parts with larger (>0.75") bores and low L/D ratios (0.5:1), but at an L/D of 2:1, honing has an advantage in speed of material removal, and over 5:1 L/D, deflection of an ID grinding
spindle may begin to introduce taper issues.
works for gears with larger bores--greater than 0.75"--and low L/D ratios of 0.5:1, but our work includes smaller diameters and relatively deep bores," Young said.
(Hamburg, Mich.) is appointed exclusive distributor in the state for precision ID grinding
machines from Swiss producer Voumard, Inc.
Fives will unveil a new multi-spindle, twin-turret, high-flexibility precision OD and ID grinding
Wheelhead specs: 10 kW motor; water-cooled precision-balanced drive motor; infinitely variable drive of OD and ID grinding
spindles; hydrodynamic multi-surface spindle bearings, and grinding wheel dimensions of 400mm x 63mm or 500mm x 80mm.
designed for many applications including, turning, drilling, tapping, reaming, gear cutting, broaching, centerless grinding, and ID grinding
. This new fluid has excellent corrosion control, contains mineral oil to provide physical lubricity, and a chlorinated extreme pressure additive to generate lubricity for heavy-duty operations.
Other Schleifring companies produce machines for external cylindrical grinding (Schaudt and Studer), ID grinding
(BWF and Studer), centerless grinding (Mikrosa), surface and creep-feed profile grinding (Blohm, Jung, and Magerle), and superfinishing (BWF).
Another wheelhead configuration is left/right with internal grinding for universal applications which allows OD, face, and ID grinding
in one setup.
For ID grinding
, the ideal solution is to turn the heavy stock, and then leave a minimum of material for the finish grind.
Custom extra-depth step chucks are used to "swallow" a longer workpiece for precision ID grinding
purposes providing a larger gripping area.
