How to remove the burrs of the pogo pins of medical devices.nucleic acid probe price

　　Before understanding why the burr of the medical device pogo pin should be removed, let's first understand how the burr of the medical device pogo pin is generated. The burr of the medical device pogo pin is formed by the plastic deformation during the cutting process, and some are castings and die forgings. Some of them are kneaded during the processing process, and some are the residual material extruded from welding, etc.

　　So, why should the burr of the medical device pogo pin be removed?

　　With the advancement of industrialization and automation, the precision requirements for the pogo pins of the parts are getting higher and higher. If the burrs are not removed, it will cause many adverse effects. For example, the pogo pins on rockets, missiles, and airplanes will not work if the burrs are not removed.

　　Once the burrs on the pogo pin or the falling metal powder enter the hydraulic or pneumatic system, it will cause severe turbulent flow or non-laminar flow, which will block the filter or pipe. Therefore, it is necessary for the hydraulic valve body and pneumatic parts to Burr removal. In the mechanical transmission system, because of tremor, the burr will fall down, which will cause the system to be stuck or the parts will be damaged. Sometimes, the burr directly impedes the mechanical movement of the component, which is especially noticeable with pistons or spool valves, etc. During the cutting process, if the burr rests on the positioning base surface of the part, the disturbance after clamping is not a real base surface touch, but becomes a point touch, which seriously affects the machining accuracy. The same is true for equipment. Due to the existence of burrs, the equipment is not qualified. If the burr is not removed from the pogo pin, the worker's hand will be scratched when loading and unloading the workpiece on the machine tool or when the equipment is processed. When subjected to higher loads, burrs and sharp edges affect the fatigue strength of the parts and the bonding force with paint and other protective layers, reducing the service life of the parts, and the pogo pin burrs also affect the appearance of the parts.
