How to measure a chamfer on a tool

The simplest operation is sometimes very complicated if the appropriate tools are not used. Measuring a chamfer is essential for some types of machining.

It is useless to measure the height or diameter for a chamfer if I do not know the angular value, but above all, to preset the tool if I do not have complete knowledge of the data required to measure.

Elbo Controlli NIKKEN has developed in a simple and intuitive way to provide the function of measuring the angle of the tool being processed or, even better, the measurement of the diameter relating to a certain length.

It is therefore a simple and immediate operation to specify how many millimeters the tool should enter the work piece, to generate the desired chamfer.

For every presetter model developed by Elbo Controlli NIKKEN there are multiple systems for obtaining this measurement. In the simplest way the value of X or Z can be ‘locked’ within the software and then automatically the value, at a given depth or diameter, is achieved for the other axis. These values can then stored ready to be sent automatically to the Numerical Control.

In other models the desired angle can be set and, by superimposing the tool profile, the value of the relative axis can be obtained.

A variation on this theme is the measurement of the tool radius according to the taper of the workpiece. In this case it is possible to use a spreadsheet which, once the angle and the insert radius are measured, returns the value of the coordinates to be entered in the NC.

Subtleties will you say? Quite the opposite! Take a scientific calculator and check how long it takes to calculate these values. In addition, there is always the doubt of having made a mistake! Use your time to improve workshop productivity, not to review your knowledge of algebra.

An easy and precise tool is never wrong, it will repeat an operation as many times as you want, without creating doubt!!!
