6. Determination of contact time In other grinding processes, e.g. face grinding, contact time t K can be calculated by relation of contact length l K and circumferential speed of grinding disc v S, equation 4 [1]. K K s l t v (4) In contrast to other grinding processes the usual influence of feed speed on contact time is not present.
Reciprocative travel (oscillation) of the grinding wheel is a line feed during grinding process and perpendicular to it periodical travel of the workpiece headstock with the mill is a cross feed. There is a stop on the workpiece headstock case, which helps to place each mill cutter to be ground in suc-cessive order strictly to the definite ...
material removal with centerless grinding. If you had 400 pcs of .442 diameter parts 6" long made from .5 diameter PHT 4140, would you turn most of the material first, then get it centerless ground, or leave it in 12' lengths and centerless grind all the material off? It needs to be ground for surface finish and size tolerance.

When applying grinding process on a milling machine, several factors that arise from the difference between milling process and grinding process, must be taken into consideration. Grinding is a chip- removal process that uses an individual abrasive grain as a cutting tool.
Surface grinding is used to produce a smooth finish on flat surfaces. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or nonmetallic substance from a workpiece, making a face of it flat or smooth.
Material removal by action of hard, abrasive particles usually in the form of a bonded wheel •Generally used as finishing operations after part geometry has been established y conventional machining •Grinding is most important abrasive processes •Other abrasive processes: honing, lapping, superfinishing, polishing, and buffing

Plunge grinding is also a discontinuous grinding process, in which machining is performed tooth by tooth. Both tooth flanks are machined simultaneously. There is a surface contact between tooth flank and grinding wheel. Due to the plunge movement of the grinding wheel in …
In order to get the desired or requested grinding result the combination of abrasives, machine and the process is crucial. Our «SUHNER Manual for cost-optimized grinding processes» is supporting you in doing so. For us the parameters of cost savings, improvement of the processes and achieving the required surface finish are crucial.
This machining process with geometrically undefined cutting edges, enables accuracies between 2 and 7 according to ISO 1328, while offering acceptable manufacturing times using universally employable grinding tools. 2 In continuous generating gear grinding, conventional vitrified bonded grinding tools are utilized in more than 90% of the cases.

The preseparator DC F60 can handle large quantities of dust, especially in the case of parquet grinding. Due to its large inlet the preseperator is also well suited to seperate coarse dirt. Because 90% of the dust is already seperated in the DC F60, the number of emptying. trips is reduced considerably for the user.
Metal grinding machines allow irregularities and superfluous parts to be removed from workpieces, achieving not only a precise and impeccable finish, but above all a unique customisation of the various parts.. Grinding is carried out using abrasive materials: from the use of abrasive tapes with coarse grains, to remove casting attachments, weld seams, residual burrs from previous mechanical ...
