Unisig's USC-2M, USC-3M Gundrilling Machines Designed for Productive Moldmaking
Unisig has introduced two models for its USC-M series designed to provide moldmakers with higher productivity in milling and deep-hole drilling applications.
Unisig has introduced two models for its USC-M series of machines for milling and deep-hole drilling in moldmaking applications. The USC-2M and -3M machines can mill and gundrill in various metals with a single universal CAT 50 spindle. The spindle’s 40 hp is said to provide high torque for aggressive metal removal and shorter cycle times. The use of a single spindle also reduces changeover times when switching between gundrilling and milling operations, the company says. A 60-position automatic toolchanger further minimizes nonproductive time. Both models can run oil and water-soluble coolant.
The USC-2M provides a nominal drill depth ranging to 1,500 mm (59.1"); the USC-3M’s drill depth ranges to 1,800 mm (70.9"). The two machines’ X-, Y- and Z-axis travels measure 2,100 × 1,500 × 850 mm and 3,100 × 1,750 × 1,300 mm, respectively. Both machine models feature an A axis with a range of +30 to -15 degrees as well as a B axis with 360,000 positions.
Both the USC-2M and -3M are built with fully enclosed machining envelopes installed above the shop floor to avoid time-consuming and costly below-ground installations.
... not to mention grinding with air. Thanks to high speed spindles powered by shop air, this job shop expands the work its VMCs can do.
This shop finds stable milling speeds quickly using a systematic pattern of test cuts.
In many die and mold shops, the choice between ram EDM and CNC milling is far less clear than it used to be. Changing technology is changing the rules.
