As a type of deep hole drilling machine, BTA is suitable for drilling large diameter. The length-to-diameter ratio can be 400:1.
BTA deep hole drilling machine of GSM drill diameter from 16mm to 150mm. The max. drilling depth is 4000mm.
Use BTA drilling head as cutting tool, which has higher rigidity than gun drill. The processing efficiency is 2-4 times higher than gun drilling machine. BTA machine fits for continuous batch processing deep hole.
GSM’s machines are introduced partial or full closed protection design accordingly. Equipped with dual arc rolling guide of high rigidity and hardness for feeding . Achieve smooth travelling and maintain long time precision.
BTA is also a kind of deep hole boring machine. GSM’s boring diameter range is from 80mm to 150mm. The max.boring depth is 4000mm.
All machines are CNC controlled.
