T2180 Deep Hole Trepanning Machine

When it comes to process large-diameter shaft holes, the conventional craft technique for processing boring and drilling will make a lot of raw substantial into chips wasted. To cater the market requests, we appoint T2180 Deep Hole Boring Machine (trepanning Machine).

Features of T2180 Deep Hole Trepanning Machine

T2180 Deep Hole Boring Machine (trepanning Machines) are mainly utilized for boring and drilling deep hole for heavy duty parts with large diameters. In order to adapt different technical demands, T2180 Deep Hole Trepaning Machines are accoutered with boring and drilling box. The cutting tools and workpieces can be rotated as per the requirements. These adopt BTA technique for drilling and push-boring technique for boring. The oil is provided by oil carriage or from the lowermost of the boring bar. The manufacturing procedures can be selected with reference to special requirements in various industries.
