Seven-Axis Deep-Hole Drilling Machine Also Performs Milling

Unisig Deep Hole Drilling Systems will display its USC-M series of seven-axis deep-hole drilling and machining centers including the USC-M38, with a nominal drilling depth of 59.1", and the USC-M50, with a drilling depth of 72". Both enable drilling diameters ranging to 2". These machines improve productivity and throughput by integrating critical mold manufacturing operations into one machine for efficient processing of large and small four-sided parts a single setup, the company says.

These machines use two independent spindles: one for gundrilling and BTA drilling, and a CAT 50 machining spindle. Combined with a rotatory table and programmable headstock inclination, these machines enable accurate deep-hole drilling as well as high-performance milling, contouring and compound angle machining capabilities.

The seven axes of control on these machines offer the B, A, X, Y and Z axes for five-axis machining operations, the W axis for the gundrilling and BTA deep-hole drilling spindle, and the U axis for machining. This combination enables 3+2 machining to reduce setups and eliminate changeovers to multiple machines.
