How to Select the ​Touch Probe?

The probes are very useful. So how do you choose suitable machine tool probes? When you select the probe, you can consider the following factors.

Ⅰ. Choose the machine tool probes according to the techniques

The enterprises could flexibly choose the probes according to the processing needs. If it is necessary to measure and calibrate the workpiece in the processing, you can select the detection head of the workpiece. You can choose the detection head of the tool to detect the tools.

Additionally, you can also choose the machine tool probes according to the processing complexity. For example, a three-dimensional machine probe is used to process the complicated workpiece, while a two-dimensional machine probe is used to process the simple workpiece.

Ⅱ. Choose the right probe stylus

The probe stylus is a key part of the probe measuring system. The probe stylus or the sensor is mainly made of pinballs, blade, and needle handle. The stylus is designed to contact with components to displace the needle's mechanism that transmits and measures. The probe sensor of the NC machine tool is the important execute part to measure as the trigger-type sensor. The probe stylus has various types, sizes, and materials. It is classified as M2, M3, M4, and M5 according to the kind of needle handle. It is good at choosing the proper stylus for your application program. We will help you to determine the correct probe stylus for your machines. As an important part of the probe measuring system, the probe stylus could affect the measurement directly. Therefore, the enterprises should consider the probe when choosing the probe stylus.

Generally, you should take the rigidity, precision, and processing environment into consideration when selecting the stylus. Choosing a rigid stylus like stainless steel or tungsten carbide stylus is necessary to produce the high-hardness workpiece and vice versa. It is also necessary to improve the accuracy of the stylus to create a high-accuracy workpiece.

In general when the shorter the measuring rod is, the longer the diameter of the measurement ball is, or the less the parts of a stylus are, the higher the measuring accuracy of the machine tool probes will be. Besides, you must choose a strong vibration resistance stylus like a carbon fiber stylus if the vibration is severe in the processing.  

The machine tool probes are the vital accessory equipment in the machining of machine tools. Installing the probe on the machines could improve the accuracy and production efficiency with low costs. It is a convenient and straightforward way to install the probe of NC machine tool for people who want to improve the machining feature of machines.
