Large deep hole drilling and boring machine T21100/T21160

Short Description:

T21100/T21160 series is a deep-hole machining machine, which can support the process of drilling, boring and trepanning the large workpiece with big diameter. While working, the workpiece rotates slowly and the cutting tool rotates in high speed and feed. BTA chip removal is used while drilling and forward metal chips removal inside boring rod by cutting liquid is for boring.

Function Description

And we used extra metal chip removal technique for trepanning which need professional trepanning cutting tools and special purpose fixture. According to the machining requirement, a travel head with rotating drilling/boring rod is equipped so the drilling/boring tools can rotate and feed.
