Diamond needle instead of ruby needle

Diamond needle instead of ruby needle

In the measurement process, in addition to the rod material, the tip material, that is, the material that slides over the workpiece is also very important. During the measurement, if the measuring material is made of ruby or silicon nitride, the roundness will become worse over time when exposed to a material as hard as ceramic or as soft as aluminum alloy. This will cause the measuring machine to slightly wear the surface of the measuring ball while scanning the hard workpiece. However, the silicon nitride ball or ruby will wear away a small amount of material on the soft workpiece. Materials that gather on the surface of the measuring ball can affect the measurement over time.

Therefore, for measuring needles made of ruby or silicon nitride, the staff must clean them regularly and change them frequently when measuring extreme materials. In the case of changing the measuring needle, remeasuring will make the measuring machine unable to be used effectively. This is the main reason why many operators give up continuously scanning artifacts. If it is a single point measurement, it means reducing the loss of the measuring needle. However, compared to the scanning process, which produces a large number of measurements in a short period of time, a single point measurement not only slows down the measurement, but also has other disadvantages. At this point, it is difficult for the staff to choose between capturing fewer measurement points at the cost of higher workload and accepting greater measurement uncertainty, or measuring many single points, reducing the measurement uncertainty but increasing the measurement time.

A solution to this problem is provided, therefore, the new and special Diamond coating Diamond! Scan measuring needle came into being. The advantage is that there is no need to check and clean the tip! The main reason is that there is no material residue and no wear on the surface of the ball during the measurement.
