Adopt effective methods to reduce metal parts machining burrs in the process of metal parts, on the workpiece would inevitably produce burrs and edges and burrs, surface for burr on the surface, the general treatment method is to use of grinding, actually many procedure, costs will increase.
For the edges and burrs, generally USES the manual tool to remove, low efficiency, also can't guarantee the quality.
Then we start from precision parts
processing process, thus in the process of processing to control the generation of burr and behind to reduce the amount of labor.
First we need to find out why will produce burr, at the time of precision machinery parts processing, the greater the elongation and strain hardening index of workpiece, when the material is cutting, the greater the deformation energy absorption by, so you can't easily be cut off, and then the burr formation.
Conversely, when the workpiece is small, the two indexes of burr in the early years of the energy absorption has been destroyed, also is not easy to form burr.
The shenzhen Xavier precision components co. , LTD. , the engineer will explain in detail, how to control in the process of precision machinery parts processing production of burr, the method is as follows: 1.
Reasonably control the cutting depth: according to our experience, the height of the burr is proportional to the workpiece cutting depth within a certain range, when the cutting depth more than this range, burr height down and ensure a constant value, the cutting depth value decreased parts burr height, referred to as burr turning point, in the precision machinery parts processing, through the control of cutting depth, can reach the height of the burr control, effectively control the generation of burr.
Reasonably control the cutting speed: when low cutting speed, cutting layer of bending deformation is bigger, energy is absorbed and chip can't leave the workpiece smoothly, to form a burr;
When high speed cutting layer to bending deformation, were separated, and won't produce burr.
Control tool Angle: in the process of precision machinery parts processing, burr and size have a lot to do with a negative Angle, mainly manifested in the burr, reduce negative Angle can be used, or wide blade cutting method, makes the formation of burr in the same process will be removed.
Control the direction of the cutting: the cutting direction and the direction of feed is tie-in, can make the burrs generated on the surface of not important or doesn't form a burr.
The above information is derived from the shenzhen gains of the company when the metal mechanical processing factory.
