Deep hole drilling experts

UNISIG is an industry-leading American producer of deep hole drilling machines. The company supplies a large variety of customers from aerospace and automotive to energy, firearms, hydraulic cylinders, military, medical sectors, smaller bespoke companies and large original equipment manufacturers (OEM.)

With unapparelled installation capabilities across Europe, Asia and America, UNISIG has the expertise to provide advanced precision-driven machinery for all jobs, with its complete deep hole drilling solutions that range from machinery to tools and automation.

The drilling capabilities include: Gun drilling, BTA, counterboring/reaming, trepanning, pull boring, skiving and roller burnishing, bottom forming, bottle boring and much more. With a wide range of stock machinery lines for diverse manufacturing needs, UNISIG can also provide bespoke-engineered machinery across all applications.

The American heavyweight was established in 1981 and since that time, has built up to a pole position across the global industry with its renowned production of gun drilling and deep hole drilling machines. Entrust Manufacturing Technologies acquired UNISIG in 1995 and then moved the company to its purpose-built headquarters in Milwaukee, USA.

Their US Milwaukee facility was expanded by over 100,000 sq. ft. in 2019 to keep up with increased production capacity demand levels. The CNC grinding machine also supports greater production, alongside regular upgrading across the production facility. The dedicated design engineers at the UNISIG Tech Centre in Milwaukee are more than happy to build customised drilling machine orders, from prototypes to finished machines.

We spoke to Philipp Steimle: Sales and Service manager for Europe to ask more about company developments, “Due to ongoing supply issues, our company is expanding its own manufacturing department. The Kellenberger CNC grinding machine we have installed will allow us to finish all the drilling spindles in-house. We have also installed a laser-cutting machine, a CNC press brake and welding stations so that we can do all the guarding and coolant reservoirs in-house to avoid delays in our machine building.”

“The UNE6 series for medical instrument drilling with its fully integrated automation is a game changer for the industry and is proving highly popular in the market. We have, and continue to invest in more in-house production rather than external third parties to keep on top of our orders.”

UNISIG is a clear market leader with a commitment to excellence to all customers. From quick machinery and part shipping orders delivered around the world, to meticulous service and repair jobs (conducted on-site and remotely), all jobs are carried out by an expert installation team made up of UNISIG engineers.

The recent addition of two new SSI Schaefer LOGIMAT® vertical lift modules (VLM) in the parts warehouse have further enhanced the already-excellent customer service. The storage units hold up to 28 tons of spare parts each providing welcomed streamlined organisation and tracking. UNISIG operators can now effortlessly access parts inventory on the touchscreen and the VLM moves the correct tray forward, whilst a laser then selects the precise bin and location of the required part. This use of automated technology has optimised the inventory storage capacity and created a smoother, more accurate retrieval system.

UNISIG leads the way in expertly engineered, high-performance gundrilling. Another prime example of this is through the use of the Dual-Spindle gundrilling machine that comes with counter-rotation (UNE12-2-750-CR). This has impressive features that include the two spindles for advanced-precision gundrilling to 12mm in diameter and 750mm in depth, at 12,000rpm. And, with capabilities to produce over 2,000psi coolant pressure, with integrated chip collection system and a touchscreen control panel, the characteristic counter-rotation of cylindrical workpieces provides next-level hole straightness that you’ve never seen before.
