When it comes to the aluminum alloy prototype, we are no strangers. Usually, the metal prototype is processed by CNC.How much do you know about the surface technology drawing of aluminum alloy prototype?
The surface drawing process of aluminum alloy prototype can be made into several kinds of textures, such as random texture, straight texture, ripple, thread and spiral texture, etc.
Random drawing is a kind of non-regular and non-obvious matte silk drawing which is obtained by moving the aluminum alloy prototype around under the high-speed copper wire brush.This kind of processing, the surface requirement of aluminum or aluminum alloy prototype is higher.
Straight drawing refers to the machining of straight lines on the surface of aluminum alloy hand plate by means of mechanical friction.It has the double functions of brushing and removing the scratches on the surface of aluminum plate and decorating the surface of aluminum plate.The ripple is generally made in a brush or brush machine.Using the axial motion of the upper grinding roller, the surface of aluminum or aluminum alloy plate is brushed to obtain the wave texture.
The thread is a small motor with a circular felt on the shaft, which is fixed on the table top at an Angle of about 60 degrees with the edge of the table. In addition, a drag board with a fixed aluminum plate for pressing tea is made. On the drag board, a neat polyester film is pasted to limit the thread race.By using the rotation of felt and linear movement of drag plate, the thread lines with uniform width are rubbed on the surface of aluminum alloy prototype.
Swirl texture, also known as optical rotation, is the use of cylindrical felt or grindstone nylon wheel mounted on the drilling machine, with kerosene and polishing cream, aluminum or aluminum alloy plate surface for rotary polishing obtained by a kind of silk.It is mostly used for circular signage and small decorative dial decorative processing.
Wire drawing is a repair process, but also can play a beautiful role, because the metal surface local scratches, the whole surface with wire drawing machine to make consistent scratches (reduce the wall thickness) cover local scratches, it is best not to use (after processing hardening, change the performance), but scratches are not good to avoid, so commonly used.Brushed not only remove aluminum surface scratches, but also beautify decorative aluminum surface double role.
