Function 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. And for processing some large solid rods or some rods with expensive material, we usually use trepanning technology by extra metal chip removal technique and with professional trepanning cutting tools and special purpose fixture. According to the processing requirement, a traveling head with rotating drilling/boring rod is equipped so the drilling/boring tools can rotate and feed.
