Translation of "Vorgeschliffen" in English

The small diameter region 4 can also be pre-ground in this step.

The teeth used can also be pre-ground and subsequently attached to the saw blade blank.

The curve of the tool was pre- grounded by a slow running drill equipped with a diamond cut head .

Large scalpel handle with cold forged iron blade, grinded semi-sharp for display purposes.

This design does not require any pre-ground works.

In this processing phase the front faces were already pre-polished.

Thus the specimen could first be rough-ground with a grinding wheel and then scratched without being remounted.

Thus the specimen could first be rough-ground with a grinding wheel and then scratched without being remounted.

Next, the test pieces were rough-ground with 1000 SiC paper and polished to high gloss on both sides with a 6 ?m diamond suspension.

Outside of this programme, we can additionally produce nearly any dimension – whether it's a blank or pre-ground.

During the grinding procedure the roughing wheel is not displaced laterally, instead the cam contour is roughed by a single plunge cut prior to the interchangeable grinding wheel being removed.

The repair of such damage is expensive, since the weld seam has to be undone, subjected to rough grinding and then welded anew.

When such parts are subject to stringent requirements with regard to dimensional accuracy and axial symmetry, ordinarily they are first machined (on a lathe), then possibly hardened, then pre-ground in a centerless grinding operation, and finally ground to size in one or more grinding operations.

The resulting roughness height Ra is even lower than it would be if the surface 8 of the soleplate 3 had not been ground or polished in a prior operation according to FIG. 2.

Polishing or grinding the soleplate prior to the fabrication of an aluminum oxide coating has the advantage that, after fabrication of the soleplate with aluminum oxide, the amount of stock to be removed from the surface in order to achieve the specified final surface roughness is less than would be the case in the absence of a prior polishing or grinding operation.

A particularly advantageous application of the process according to the invention is when, after the blank is produced, first the back face of the cutting insert is pre-ground a certain amount, then the front face is ground until the desired tooth width of the finishing cutter is achieved, and finally the back face is given a final grinding until the desired thickness tolerance of the cutting insert is achieved.

For the purpose of obtaining a uniform layer thickness, the finish grinding step of the roll after coating must be carried out at the temperature at which the roll has been pre-ground.

The wooden slabs are sanded, but at any rate must be further treated through fine-grinding and filling, if necessary.

One disadvantage of this method is that the volume of the blank has to be defined very accurately, and so it must be exactly pre-ground, or produced in some other way.

The two-high rolls are pre-ground and on their surface coming into contact with the stock typically have an arithmetic mean roughness Ra of less than 0.03 ?m.

In the region of the pressing surfaces, the pressing elements, accommodated in a swinging manner, can be pre-ground to a mean diameter of the envisaged diameter range, such that, starting from this mean curvature, only slight surface-shape adaptations are required upon being pressed on.

Subsequently the scissors are pre-ground entirely and afterwards polished, for which purpose a grain size 400 or 600 is used.

Processing: The wood surface to be treated must be sanded with 180-240 grit sandpaper (e.g FINISHING PAPER, YELLOW) and all dust and dirt removed (stained wood should NOT be sanded).

By using ceramic media, the surface is pre-ground without pores and then polished to a high gloss or high gloss density using special process media.
