Flat Drilling Teeth of auger and bucket for rotary drilling rig
Process flow of bucket teeth: sand casting, forging casting and precision casting.
Sand casting: the cost is the lowest, and the process level and bucket tooth quality are inferior to those of precision casting and forging casting.
• Forging and casting: the cost is the highest, and the process level and bucket tooth quality are also the best.
• Investment casting: the cost is moderate, but the requirements for raw materials are very strict, and the process level is relatively high. The wear resistance and quality of some precision casting bucket teeth even exceed that of forging and casting bucket teeth due to batching. At present, the precision casting bucket tooth is the mainstream manufacturing process in the market.
