7. OPERATION OF THE WORK

7.1.Mounting and dressing of the grinding wheel before the first operation

After you have moved the machine to its final place of working, take the wheel and make a sound check as well as optical control of damage. Mount together the grinding wheel with its support

After you have mounted the grinding wheel support, place the wheel on the motor spindle (see section 7.3).

After the grinding wheel is placed correctly on the motor spindle and the grinding wheel cover is mounted, start dressing the grinding wheel first (see section 7.2).

Only after observing these steps, a save and correct operation is possible!

7.2.Dressing of the grinding wheel

For dressing of the grinding wheel, please release the clamping lever and place the prism rest on the 150º graduation line.

Fix the diamond dresser device in the prism and fix the prism with the knurled fixation screw in the bottom boring hole of the prism rest.

Move the motor feed with the knurled nut slowly towards the turning grinding wheel. When the diamond pin touches the grinding wheel, then move the motor feed back and forth. Do not feed more than 1-2 scale graduations. For sheet metal drills, forstner drills or milling cutters, you need a grinding wheel of suitable shape.

By an adequate adjustment of the prism support, with the attached dresser, it is possible to dress the wheel in any shape requested.

7.3. Change of the grinding wheel

For changing the grinding wheel, disconnect it from electric current!

Loosen both head cap nuts (1+2) with a 10mm engineers wrench and remove the grinding wheel cover as shown on the picture.

Now open by use of an allen key SW 4.0, the screw in the center of the wheel support. Now you can remove the grinding wheel from the motor spindle. Open the grinding wheel support with the supplied key and change the grinding wheel.

When placing the support on the motor spindle, pay attention that the threaded pin is in the notch of the motor spindle (picture 3). Now fis the screw in the certer of the wheel support with the allen key SW 4,0 and mount the grinding wheel cover in the opposite sequence. Take care that the grinding wheel support is mounted correctly.

After the grinding wheel change make a 1 minute test turn. In case of uncommon performance, switch off the machine and check for cause of failure.

The ELITE B 20 is not allowed to be operated without correctly mounted grinding wheel cover!

7.4. Grinding of drills placing and adjustment of drills

The reversing prism comprised a range of 2-20mm. The insertion and alignment of the drill is achieved in the most simple manner conceivable. Open the prism by means of the knurled head screw, provided for this purpose. Now insert the drill to be ground inside the prism.

Keep the drill projecting about 15-20mm beyond this prism edge. The prism jaws are pressed together by a slight turn of the knurled screw. The thus inserted drill is held tight in this position, but it can still be turned easily as this is important fo the alignment. Now it is only necessary to align the cutting edge of the drill in parallel to the two indicated marks (Mark A = right-hand drills; Mark B = left-hand drills)

The prism is to be tightened by hand only a hereafter, the grinding operation can be started.

Deviating from this basic adjustment, you can change your relief angle depending on the material to be drilled.

You want a higher clearance angle - a higher cutting capacity, then revolve the drill slightly to the left (shorter graduation mark on the prism). If you want less relief - a lower cutting capacity, then revolve the drill slightly to the right (longer graduation mark on the drill). You will thus obtain the correct cutting edge and angle for every kind of material.

In case of a broken drill, having no cutting edge for adjustment, grind the drill to get a truncated end. Align the cutting corners as closely as possible to the adjustment marks and regrind the drill until a new cutting edge appears. Thereafter the adjustment is to be carried out as before.

7.5. Adjustment of the top angle

In order to work always in conformity with the properties of the material, you have the opportunity to adjust every top angle that is possible.

The common top angle are 118º, 130º and 180º degrees.
The angles are solidly marked on the prism slide. They can easily adjusted by opening the clamping lever (see section 5.3) and by moving the prism ret.

7.6. Grinding of the drills

The prism, with the well aligned drill is slipped on to the prism swing pin and revolved in front of the grinding wheel. Simultaniously move the drill feed carriage towards the grinding wheel by means of the knurled nut until one side of the prism is well formed

Note the scale mark on the nut. Move backward the feed carriage by 2 to 3 scale marks closer to the grinding wheel.

The drill in this position is swiveled until no further formation of the sparks are visible.

In order to achieve the best possible cutting edge symmetry, the prism is reversed again by 180º without any alteration of the position of the drill feed carriage. The other siede is ground until no more spark are visible.

7.7. Step drills

Grind the cutting edges of the first step same as standard twist drills. The cutting edges of the second step are likewise aligned in parallel with the indicated marks of adjustment (see section 7.4). The drill inside the prism is then pushed forward until the second step passes by the grinding wheel and touches the grinding wheel.

Using the knurled nuts 7 and 9 you can do the fine adjustment of the drill to the grinding wheel. Thereafter you resharpen the cutting edges by way of the reversal of the prism as described before for standard twist drills.

7.8 Sheet metal drills, wood drills, forstner drills and cutters

For the above mentioned drills it is recommended to use specially dressed grind wheel faces

Release the clamping lever of the prism rest and place on the adjustment line of the drill feed carriage

The adjustment of the drills is identical to twist drills. The fine adjustment of the drill to the grinding wheel is carried out with the screws (see section 5.3, num. 7 and 9)

By moving forward with the knurled nut, sharpen one cutter and after reversal of the prism, sharpen the second side (see section 5.3, num. 9). For milling cutters having 3 or 4 cutting edges you will need the magnetic depth stop. (optional).

Forstner drills in contrary to other drills are not adjusted according to adjustment marks on the prism, but aligned to the stagnant grinding wheel.

The grinding operation is same as for cutters.

7.9 Web thinning

With the new clamping prism it is now possible to thin the web of the sharpened drill

1. The boring holes A and B are for grinding of cutters and drills with 4 facet shape
2. The bore C is for web thinning

For web thinning let project the drill 25mm outside the prism and do not change the position of the drill in the prism. Fix the prism with the knurled screw in hole C

Use the upper boring on the prism support. Loosen the clamping lever and move the prism support to 90º.

By use of the prism and motor feed, thin the web of the drill by using the left edge of the grinding wheel.

After one side is finished, note the graduation marks on the prism feed screw and move back for one turn. Now reverse the prism for 180º, fix again in hole C and move forward with the prism feed to the same graduation mark on the knurled screw.

7.10 Cross or facet grinding

After the sharpening procedure, you have the possibility to change the standard twist drill shape to a cross or facet grinding.

The twist drill remains in the prism clamp without any changes in setting. Fix the prism with the fixation screw M4 in hole C (see section 7.9). Open the clamping lever and turn the prism support to 150º.

Move with the motor feed to the left, till you touch the cross cutting edge of the twist drill by the right edge of the grinding wheel.

Dive slowly into the center of the cross cutting edge by moving forward the prism feed. Notice the position on the feeding scale, move back, losen the fixation screw, reverse the prism for 180º. fix the screw again and move slowly forward again to the same position.
