Deep-Hole Drilling Machines on Display

Unisig is showcasing its USC-M series of seven-axis deep-hole drilling and machining centers. Well-suited to mold production, the series enables manufacturers to process large and small parts with four-sided machining capability in a single setup. Currently, the series comprises two machines: the USC-M38, which offers a nominal drilling depth of 59.1", and the USC-M50, which extends the nominal drilling depth to 72". Both accommodate drilling diameters ranging to 2".

The drilling machines are equipped with two independent spindles: one for gundrilling and BTA drilling and a second CAT 50 machining spindle. When this additional capability is combined with a rotatory workpiece table and programmable headstock inclination, accurate deep-hole drilling and all standard high-performance machining capabilities are available within the working envelope of the system, the company says.

The seven axes of control consits of B, A, X, Y and Z axes for five-axis machining operations, the W axis for the combined gundrilling and BTA deep-hole drilling spindle, and the U axis for machining. This configuration provides 3+2 machining to make deep-hole drilling and machining of compound angles faster and easier, and improves productivity and throughput by reducing setups and eliminating change-overs to multiple machines. According to Unisig, using a deep-hole drilling headstock capable conventional gundrilling and BTA high-performance drilling can be five to seven times faster than gundrilling alone. Available accessories include full-enclosure guarding, a 120-position automatic toolchanger, a laser tool pre-setter and probing.
