Drilling of brass blanks

Drilling is a process of machining, in which a drill is used to obtain or increase the diameter of the hole. The cutting part of the drill is pressed against the workpiece and rotates at a speed of hundreds to thousands of revolutions per minute. This causes the cutting edge to process the workpiece by cutting the shavings from the hole when it is drilled.

Technical difficulties

Brass is an alloy of copper with zinc. Increased percentage of zinc makes the alloy non-plastic. For such brasses, the main problem during drilling is the timely evacuation of chips from the hole, especially if the depth of the hole is too large, or if the return value of the drill during drilling is insufficient. Conversely, if drilling a soft brass that contains a reduced percentage of zinc, the shavings can wrap around the drill and cause it to radially run out, impairing the quality of the surface.

CNC

In CNC machines, a process called intermittent drilling is used to prevent excessive accumulation in the hole (a hole is considered to be deep in relation to the brass, a depth about three times the diameter of the drill bit diameter). Drilling of brass is possible in a ribbon way, when the drill is fed deeper into the hole, it rises slightly upwards. In this case, the chips are torn and extracted outside. Tapping of brass is more productive than intermittent.

Cutting of brass billets

The brass cut can be carried out by methods of plastic shear (using shears or combined scissors), by mechanical methods, as well as by electroerosive cutting techniques with an unprofiled (wire) electrode. During the cutting of thin profiles, EDM is used, since the rigidity of the workpiece, clamped in the chuck of the machine, is insufficient. When cutting profiles of medium size, band-saw cutting machines are used. When cutting, the average values of the material feeds are used, but the increased speeds of the reciprocating movement of the cutting tool. As the cutter approaches the opposite end of the workpiece, the feed is reduced. During the cutting of brass pipes, which contain a reduced percentage of zinc, it is mandatory to use lubricating and cooling liquids.

Optimization

Recently, the technology of radial cutting of solid and tubular brass blanks has become increasingly popular. At the same time, the force on the cutting tool is reduced, and the quality of the surface increases. The disadvantage of the radial segment is a slightly reduced performance of the operation. Regardless of the cutting method, after finishing the main operation, it is necessary to perform the cutting of the cut edge to remove the burrs. During the shearing, the finished dimension blanks are subjected to straightening.
