UNISIG, founded in 1981 and operating today from Menomonee Falls, Wisconsin as a division of Entrust Manufacturing Technologies, is the leading American builder of deep hole drilling machines - a specialist manufacturer whose gundrilling and BTA platforms reach bore depths and depth-to-diameter ratios that general-purpose machining centers cannot. The UNE series gundrilling machines bring deep hole capability into a conventional job shop at a moderate investment, the UNI series handles high-production and high-accuracy work, the B-Series delivers high-power drilling in difficult materials, and the USC-M series seven-axis deep hole drilling and machining centers combine drilling with four-sided machining in a single setup. UNISIG machines are found in mold and die shops, energy and oil and gas component plants, aerospace and defense manufacturers, and medical device production across North America, running Siemens or Fanuc controls.
Sellers of UNISIG equipment are most commonly mold and die shops changing product mix, energy sector suppliers adjusting to demand cycles, and contract manufacturers consolidating a deep hole drilling department after a program ends. Because UNISIG builds a specialized machine in relatively low volume, used units are scarce and draw a focused, motivated buyer pool: shops that need a specific drilling depth capacity and cannot wait on a new-build lead time. Buyers evaluate these machines on drilling diameter and depth range, spindle and coolant pump horsepower, coolant pressure and filtration, whip guide and tooling package, control generation, and overall condition.
Resell CNC handles used UNISIG gundrilling machines, BTA deep hole drilling machines, and USC-M drilling and machining centers, and we work with buyers across North America who are actively sourcing deep hole drilling capacity they cannot easily buy new. Tell us your model, year, control configuration, tooling and accessories, and current condition, and we'll handle the listing, buyer outreach, and logistics to get your machine sold efficiently and at a fair market price.
