Deep-Hole Drilling and Milling Machines Streamline Mold Production

At Amerimold 2018, June 13-14 in Novi, MI, UNISIG will showcase its USC and USC-M series machines that combine deep-hole drilling and milling capabilities to allow mold shops to reduce set-up time, increase accuracy and eliminate mold design restrictions associated with traditional machining centers.

USC series column-type machines feature enhanced machine alignment, rigid construction and choice components designed to provide a reliable and compact solution for mold manufacturers to perform BTA and gundrilling operations and generate accurate holes up to 1.5" in diameter in large workpieces. Available in table weight capacities up to 50 tons, machines in this series are suitable for workpieces such as mold plates and frack pumps. For increased part processing capability, milling spindles and rotary tables are also available as options with USC series machines.

Visitors will learn how the USC-M series of 7-axis deep-hole drilling and machining centers offer a suitable solution for improving productivity and efficiency in mold production. These machines allow manufacturers to process large and small parts with four-sided machining capability in a single set-up.

The USC-M series machines utilize two independent spindles: one for gundrilling and BTA drilling and a second CAT 50 machining spindle. When this additional capability is combined with a rotary 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 seven axes of control on the M-Series machines utilize the B, A, X, Y and Z axes for 5-axis machining operations, the W-axis for the combined gundrilling and BTA deephole drilling spindle and the U-axis for machining. This provides 3+2 machining to make deep-hole drilling and machining of compound angles faster and easier and is engineered to improve productivity as well as throughput by reducing set-ups and eliminating transfers to multiple machines. "In fact, using a deep-hole drilling headstock capable of conventional gundrilling and BTA high-performance drilling has proven to be five to seven times faster than gundrilling alone," said a company spokesperson.

UNISIG engineers and manufactures both the USC and USC-M series in the U.S. with high-performance components. The company also offers a full complement of options for these machines to further enhance their milling and machining functions, including full-enclosure guarding, a 120-position automatic tool changer, a laser tool pre-setter and probing.

Upon machine installation, UNISIG provides its customers with comprehensive training that involves machine operation and process optimization as well as gundrill tool sharpening. The company also offers customers reference information and practical advice for proper machine operation.
