Drilling and Machining Centers Leverage BTA Process

Unisig’s USC-M series drilling and machining centers combine several processes into one machine capable of drilling and machining all four sides of a workpiece, reducing setup time and increasing accuracy for mold manufacturers. Two sizes are available. The USC-M38 model is capable of drilling and machining workpieces ranging to 2 m in length in a single setup, while the larger USC-M50 can accommodate 3-m long workpieces, the company says.

Both machines use traditional gundrill tooling as well as the BTA drilling process for waterline drilling. When combined with the second independent CAT50 machine quill, this drilling capability enables performing all machining and drilling functions within the full working envelope of the system, says Unisig. The machines are equipped with a 360-degree workpiece table as well as a programmable drilling and machining headstock offering 30 degrees downward and 15 degrees upward motion.

The machines can be equipped with an automatic toolchanger accommodating as many as 120 tools, laser tool presetting, workpiece probing, automatic pallet transfer, and full-enclosure guarding with a mist and smoke collection system.
