Do you want to burr the finger spring?

Why is the spring deburring? First of all, how do burrs happen? Some are caused by plastic deformation during cutting, some are fly-edges of castings, die forgings, some are extruded during machining, while others are extruded by welding. Produce residue, etc. With the improvement of industrialization and automation, the precision of partial springs is more and more demanding. If the burr is not removed, it will cause adverse effects in many ways.

For example: the springs in rockets, missiles and aircraft. If the burrs were not removed, the consequences would be unthinkable. Burr or separated metal powder on the spring, once in the hydraulic or pneumatic system, will cause severe turbulence or non-laminar flow, and can cause filter or pipe clog. Remove burrs. In mechanical transmission systems, burrs may fall off due to vibration, resulting in system jams or part damage. Sometimes burrs directly interfere with the mechanical motion of the assembly, especially in pistons or spool valves. During the cutting process, if the burr is placed on the positioning base surface of the part, the interference after clamping is not the real base contact, but the point contact, which seriously affects the machining accuracy.

Assembly is the same, because there is a burr, resulting in assembly failure. If the spring does not remove burrs, it will scratch the worker's hand during loading or unloading the workpiece onto the machine tool or during assembly. When subjected to higher loads, burrs and sharp edges affect the fatigue strength of parts and their adhesion to paint and other protective coatings, thus shortening the service life of parts. Spring burrs can also affect the appearance of parts. Given the serious consequences mentioned above, glitches are like mouse droppings falling into a pot of porridge, which must be removed in advance and must be avoided.
