The following small series of precision small hole processing manufacturers will explain to you the measures that should be taken for precision small hole processing.
1. Design the drilling tool clamping device to increase the rigidity of the drill. The drilling tool clamping device adopts a wrapping structure to reduce the exposed part of the drill bit, so as to improve the rigidity and strength of the drill bit. And set the cutting fluid flow channel, with the help of a certain pressure cutting fluid, the chips are forced to be discharged, so as to achieve the purpose of chip removal and cooling.
2. Improve the drilling tool. Professional small hole machining In order to ensure the surface roughness requirements of deep cavity small holes, it is necessary to use a reamer for finishing after rough machining with a twist drill. In order to improve the toughness of the reamer and prevent the damage of the reamer during processing, the reamer is improved by halving the number of teeth, reducing the feed rate, increasing the chip removal and chip holding space, with good toughness and good heat dissipation. and good chip removal.
3. Realize manual feed drilling, effectively reducing the possibility of drill breakage. It is designed with a drill sleeve, which can realize manual feed drilling. Even if the processing equipment is very precise, it is mechanical feed, which cannot feedback the cutting force. However, manual feeding can control the appropriate feed amount. Once the cutting force is too large or there are signs of drilling deviation, the drill is returned immediately. The matching clearance between the drill sleeve and the tooling body is controlled within 0.005mm, which is especially effective for processing small holes with deep depths.
