What is the method of deep hole processing of aluminum alloy prototype

The aluminum alloy prototype is one of the industrial prototypes. Let's take a look at its composition and use. Aluminum Alloy is a general term for aluminum-based alloys. The primary alloy elements are copper, silicon, magnesium, zinc, manganese, and nickel, iron, titanium, chromium, lithium, etc. The density of aluminum alloy is low, but the strength is relatively high. It is close to or beyond the high-quality steel. It has good plasticity and can be processed into various profiles. It has electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry, second only to steel.

three methods for deep hole machining of aluminum alloy CNC prototype

1. The deep hole is processed by the set knife. Deep hole with large aperture (Usually the diameter is greater than 50mm)It is advisable to use a set knife for processing. This method reduces the cutting load and then increases the productivity and reduces the material consumption. The kit knife used is used. When the diameter is small, all welding types are selected. When the diameter is large, it can be assembled or adjustable. The tool should be equipped with wear-resistant strips for guiding. The materials can be clip-on glue, hard alloy, rolling bearing, etc. , and the cutting edge planning should also consider chip splitting and Chip breaking. It is also suitable for mass production.

2. The twist drill with the long handle is processed on the general machine bed. The long handle twist drill is to weld the long handle on the usually twist drill. Because of the large axial force during drilling, the symmetry of the two edges of the drill bit is not easy to grind, the quality of the horizontal edge grinding of the drill bit is not easy to guarantee, and the rigidity of the knife pole is poor, so it is easy to oscillate during processing, because the bit has limited space for chip tolerance, it is necessary to process a length after the chip removal and cooling tool (Usually 5 ~ 10mm)Exit the drill bit. For the spindle with a long axis hole, the method of drilling from both ends should be selected. Therefore, this deep hole processing method has poor quality, low productivity and high labor intensity, but because of its simple tool manufacturing, it can use general equipment, so it is used more in single-piece and small-batch production.

3. The deep hole drill is selected to be processed on the special deep hole drill bed. The Deep Hole Drilling is used to process the deep hole well. The problems such as tool deviation, tool cooling and chip cutting in the deep hole processing are solved, which significantly improves the processing quality and productivity. Can be processed to 10 ~ Deep hole of 30. Deep hole processing machine tool can be used with a special Deep Hole Drilling bed, or the usual lathe can be modified
