Improved grinder operation also will enhance the form, fit and function of your parts, resulting in happier customers and managers. There are seven ways to improve production on your grinding machines: #1 Repair. The first function of grinder repair is to fix broken components and get the machine up and running again.
grinding for difficult to machine work pieces. They also reduce thermal effects of the near-sur-face microstructure and assure extremely long profile lifetime. WINTER DMC and BMC grin-ding wheels can be profiled by crushing directly on the grinding machine. 1847 WINTER produced lithography dia-monds, replacing the conventional steel tips. 1969
The Junker grinding machine masters this with ease, and for optimum accuracy the machine produces parts with a total lead variation of +/- 3 microns and a profile accuracy of less than 6 microns. For the different flute shapes and for rough and finish grinding, the machine is equipped with a wheel changer.
With the Multigrind Horizon 3D-CAD package and the 3D-CAM package, Hermle says aerospace users can cover about 90% of grinding tasks in turbines. "If users also want to machine teeth for drive functions, where sliding fits are important, then they will also need the package for rotationally symmetrical workpieces," Hermle says.

Fives' I.D. grinding systems are equipped with Landis-Bryant spindles that contain super-precision bearings and permit operation at high speeds. They are powered by in-house designed induction motors to provide enhanced performance for efficient machining. For more information contact: Fives Landis Corp. 16778 Halfway Blvd. Hagerstown, MD 21740.
The dressing and grinding experiments have been carried out on a Blohm Profimat 407 surface grinding machine. The dressing system, using a diamond profile roller, is integrated into the machine . To achieve high cutting speeds and small wear rates, a wheel diameter of 300 mm has been chosen.
The number of parts per dress was 40, the dress depth was 0.010 ", dressing cycle time was 15 minutes and grinding cycle time was 42 seconds. Abrasive cost per part was 20 cents. To eliminate the variance in the wheel form and improve productivity, a Walter Power grinder was fitted with a MaxTorq electric spindle, a BPR diamond profile roll and ...
In the late 1970's, Continuous-Dress Creep-Feed grinding (CDCF) came onto the scene. Instead of dressing between parts or passes, the grinding wheel is constantly dressed while it's machining. Not only is the grinding wheel held continuously in a constant state of maximum sharpness, but the form is accurately maintained.
Once the tool-life criterion is reached the grinding process is interrupted and the grinding wheel needs to be conditioned. To reduce machine and clamping influences and interrupt times of the grinding process, dressing today is normally done by a dressing device on the grinding machine in sequence to the grinding process.
