Technical Information

Quality:

KIMTOP carbide burrs are manufactured using high quality types of carbide and modern CNC automatic grinding machines in order to guarantee precision and repeatability of angle, profile and twist. Carbide burrs manufactured to your drawings or details assist in solving your particular stock removal problem.

Application:

The best results are obtained by selecting the recommended cut and speed.

Power tools:

Electric and pneumatic power tools are used; the bearings should be in good condition and the collets running true. Vibration and chatter will cause premature wear and tooth breakage. High pressure will reduce tool life and decreases tool efficiency.

Shanks:

We recommend that the largest shank diameter possible is selected from the appropriate list; this provides maximum safety. Other shank diameters and lengths are available on request.

Robot application:

KIMTOP tungsten carbide burrs are precision tools, and have produced excellent results when used in conjunction with industrial robots. We can also develop the optimal burr for your particular application.

Coated:

The reasons for producing cutting tools with hard coatings such as TiN, TiCN, TiALN and LTE are as follows:

• to increase tool life

• to reduce machining forces

• to improve chip removal

The increase in tool life is mainly the result of the considerably higher surface hard ness of the coating in comparison to the base material of the tool itself. In addition, due to the high chemical stability, it mini - mizes the reaction between the cutting edge of the tool and the chip to be removed.

The reduction of machining forces and the improvement in chip removal are achieved through a reduction in the friction between

the free cutting zone of the tool and workpiece on the one hand,

and the cutting edge of the tool and the chip removed on the other.

The reduction in friction depends on the coating improving the surface finish and as previously described by largely avoiding any chemical reaction.

Our technicians would be pleased to help you in the selection of the correct coating.

Special tools:

Tungsten carbide burrs manufactured to your design or drawing guarantee the KIMTOP high quality standard, and can therefore assist in solving you particular machining problem.

Packaging:

We use plastics-packaging; please select the respective packing unit from our product lists.

Recommendations for use:

Select the cut to suit the material to be machined. Please kindly follow the principle: The harder the material, the finer the cut! The correct selection of speed is the basis of achieving optimum machining results and long tool-life; please refer to the adjoning table. Use the highest possible speed within the indicated area. Too low a speed results in vibration, chipping and premature wear! Reduce the speed of the burrs only when using in large arc angles or when used on low heat conducting materials. Never let the shank and head be come discoloured blue. For safety reasons, extended shanks should also be run at low speed. The power of your machine should be compatible with the machining process. A reduction in RPM due to lack of power – particularly common with pneumactic tools – should be avoided. Collets must run true. Run-out and vibration will result in chipping and premature wear.

For the same reasons, take care that the machine bearings are in perfect condition.

To avoid vibrations and shank breakage, select the shortest shank overhang as possible.
