Needle selection to maintain the accuracy of the good habit

Choose a good habit to maintain accuracy.Which needle should I choose?Overview of needle selection:• Try to choose a short measuring needle, the shorter the measuring needle, the higher the hardness• Choose as much as possible to avoid the interference of the rod and the influence of the surface finish of the workpiece under test• Minimize connection points as it may reduce the accuracy of bending and offsetting• The star needle allows for the simultaneous use of up to five needles and is very convenient for measuring some features of the cavity, such as the annular groove in the hole.In addition to the above conventional methods, there are three scenarios that should be considered:1. Test the accuracy level of the ballIn order to achieve high accuracy, most measuring machines are provided with a 5 stage measuring ball. When buying replacement parts, never choose a lower grade (grade 10) gauge needle, as this usually results in a 15% loss in overall accuracy of the machine. ...

Principle and problems of measuring needle calibration in CMM

The measuring accuracy and working efficiency of CMM are closely related to the calibration and selection of measuring needle. Before the measurement work, we must reasonably choose the measuring needle and do a good job in the calibration of the measuring needle, because the measuring ball of the measuring needle has its own size, the different positions of the measuring parts can be in contact with the different positions of the measuring parts of the ball. Therefore, the measurement data contains the value of the measurement ball itself, and the measurement needle calibration is the process of measuring the size of the ball itself. Especially in the calibration of different length and position of the measuring needle, the size of the ball error is very important to the measurement results. 1. Principle of measuring needle calibration In the process of measurement and sampling, when the measuring needle touches the surface of the measured part, the measuring head system will display...

What is a measuring needle?

What is a measuring needle?The measuring needle is a part of the measuring system, and the contact with the workpiece to be measured results in the displacement of the probe mechanism. The measurement results are obtained by processing the generated signal. The appearance of the measured workpiece will determine the type and size of the measuring needle. In all cases it is important to measure the stiffness and sphericity of the needle. In principle, the measuring needle is the coordinate measuring machine. "Tool" is like the relationship between turning tool and lathe, milling cutter and boring cutter and milling machine. When measuring with a contact measuring head, the machine tool uses a measuring needle to collect data points on the workpiece surface. The points generated by each trigger are defined using X, YZ coordinate values. These points are then used to calculate features, size, shape and position. The difference is that the scanning measuring head collects contin...

The principle of coordinate measuring needle calibration is analyzedThe measurement accuracy and efficiency of CMM are closely related to the calibration and selection of measuring needle. Before measurement, the measuring needle must be reasonably selected and calibrated, because the measuring ball of the measuring needle has its own size, and the different directions of the measuring parts may be in contact with the different directions of the measuring ball. Therefore, the measurement data contains the value of the ball itself, and the needle calibration is the process of measuring the size of the ball itself.

Some problems that should be paid attention to in coordinate needle detection

Because CMM needle is widely used in industrial production measuring equipment, the use frequency is higher and higher, in industrial production, many enterprises almost use high-precision measuring equipment, the use frequency is higher and higher, many enterprises rely on product quality review CMM needle, CMM needle measurement mold also need to pay attention to, today small explanation CMM needle need to pay attention to some matters:1. When testing mold products with three coordinates, it is necessary to test according to the operating standards of three coordinates testing, which is relatively basic and important. Before inspecting the workpiece, we should check the position of the probe to see if the probe is at the origin. If the probe is not at the origin position, we must remember to return it to the origin position. Secondly, when detecting the die workpiece, we should check the space of the workbench. Due to the large volume of most die workpiece, wide operating workpie...

Check the needle to pay attention to the problem

Reasons why the calibration value is less than the nominal value:After understanding the principle of probe calibration, we can easily explain why the needle calibration value is less than the nominal value.1. Trigger measuring needle is equivalent to lever structure in principle. When touched, the head sensor must be able to trigger (the equivalent of a switch we normally use) in order to send a signal. Because the measuring needle has a certain relation to the standard length, so the ruby ball of the measuring needle needs to run a certain distance after touching the standard ball, so that the sensor triggers the signal. The longer the measuring needle, the greater the distance. Thus, the delay in the touch transmission signal makes the diameter of the fitting sphere less than the sum of the diameters of the ruby sphere and the standard sphere. When the software in the measuring control cabinet subtracts the diameter of the fitting ball from the standard ball (having entered the actu...

How to ensure the quality of CMM measuring needle?

How to ensure the quality of CMM measuring needle?The tip of a CMM needle is usually a sphere made of artificial ruby. The most commonly used sphere-measuring indicators are level 5 and level 10. Of course, the lower the level, the better the ball. The selection of CMM materials is related to scanning applications. For example, in industry, probe needles in silicon nitride materials are often used to scan aluminum or cast iron materials to avoid "adhesion damage" from material interactions on the surface of ruby test balls. In addition, the choice of measuring rod material is also very important.The measuring rod must be designed for maximum stiffness so that even if the rod is bent to the lowest point, it will not break. In addition to the stainless steel commonly used in the market, tungsten carbide rods with small diameter or very long rods are also a good choice. When choosing a coordinate measuring needle, we can choose the shortest measuring needle as possible. The long...

Ruby needle measuring

Ruby needle measuringThese direct probe pins are suitable for most probe measurements. They are equipped with high-sphericity industrial ruby balls. Ruby is a very hard ceramic material, so the ball wears very little. It also has a low density, so that the mass of the measuring tip is the lowest, avoid the equipment operation or vibration caused by the wrong trigger. Ruby ball can be installed in non-magnetic stainless steel. Ceramic, carbon and other materials ensure the stiffness of the whole measuring needle.
