Why Does The Cnc Machine Tool Install The Probe?

What Is A Machine Tool Probe

The measuring head of the machine tool is a kind of measuring equipment which is arranged on the numerical control machine tool. According to the function, the machine tool probe can be divided into two types: workpiece detection probe and tool detection probe. According to the signal transmission mode can be divided into four types: hard wire connection type, induction type, optical type and radio type.

The measuring head of machine tool is usually installed on CNC lathes, machining centers, CNC grinding machines, etc. It can directly measure the size and position of the cutter or workpiece without human intervention in the processing cycle, and automatically correct the offset of the workpiece or cutter according to the measurement result, so that the same machine can produce parts with higher accuracy. Because it can improve the quality of processing, and low cost, so favored by enterprises.

The Function Of Machine Tool Probe

The most important function of the machine tool probe is to help the machine measurement and machining correction. It has the following functions.

1. Automatic identification of machine accuracy error and automatic compensation of machine accuracy;

2. Replace the manual to carry out automatic segmentation, edge searching and measurement, and automatically correct the coordinate system and automatic tool filling according to the measurement data;

3. Measure the direct march curve of the workpiece;

4. Automatic comparison of measurement results and report.

To sum up, the measuring head of the machine tool is an auxiliary measuring equipment in the machine tool processing. As it is installed on the machine tool, it can be measured and calibrated during machining, which reduces the clamping process and can improve the efficiency and quality of machining to a certain extent.

Importance Of Machine Tool Probe

It can be seen from the function of the machine tool probe mentioned above that the machine tool probe, because it is directly installed on the machine tool and can automatically measure, record and calibrate, plays an active role in reducing the machining process, reducing labor cost and improving the machining accuracy and efficiency of the machine tool.

At present, the whole machine tool manufacturing in China is in the middle and low level. It is believed that the measuring head of machine tool is an effective means to improve the machining accuracy and efficiency of domestic machine tools.

How To Select Machine Tool Probe

Read so many, have the reader to be about to ask, since the machine tool probe is so good, how should be equipped to the machine tool when the selection of their own probe? Don't worry, listen to me slowly. When selecting the machine tool probe, you can refer to the following aspects.

1. Select the probe according to the processing

Enterprises can select the probe flexibly according to the processing needs. If the workpiece needs to be measured and calibrated during the processing, the workpiece detection probe can be selected. For tool detection, tool detection probe is selected. In addition, the machine tool probe can be selected according to the processing complexity. For example, 3D machine tool probe is used when processing complex workpiece, and 2D machine tool probe is used when processing simple workpiece.

2. Select the appropriate needle

As an important component of the measuring system of machine tool probe, the measuring needle directly affects the measurement result of machine tool probe. So enterprises can use the probe as a reference when selecting the probe.

Generally speaking, the selection of probe sticks to three principles, namely, rigidity, precision and processing environment. When the workpiece has a high hardness, it is necessary to choose a rigid measuring needle, such as stainless steel measuring needle or tungsten carbide measuring needle. When the machining accuracy of workpiece is required to be higher, the measurement accuracy of the needle should also be increased. Generally speaking, the shorter the measuring rod, the larger the diameter of the ball, or the fewer the number of needle components, the higher the measurement accuracy of the measuring head of the machine tool. In addition, if the vibration during processing is large, choose a needle with strong anti-vibration performance, such as carbon fiber needle.

The measuring head of machine tool is an important auxiliary device in machine tool processing. For those enterprises who want to improve the performance of machine tools, it is a simple and convenient way to try to install the machine tool probe.
