Description
- The depth of the thread hole should be less than the thread diameter. It is better to use the rocker drill to process the hole. The speed should not be too high. Use soybean oil as cutting fluid.
- Generally 8 mm below the thin hole drilling effect is good, the production efficiency is high.
- This wire attack is generally used for through-hole, inner silk should not be too deep, blind hole can not be used.
