As seen in MMS

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.

Guide Highlights Durable Tooling
A Durable Tooling Guide available from Unisig features information on the company’s components and tooling for BTA deep-hole drilling machines.

Combining Skiving and Burnishing for Cylinder Bores
Machines engineered specifically to perform skiving and roller burnishing operations deliver precise roundness tolerances and quality surface finishes.

Machine Line Designed for High Precision Skiving and Roller Burnishing
Unisig Deep Hole Drilling Systems offers the S-series machine line for the skiving and roller burnishing process at IMTS 2012.

Pull Boring Highlights the Capability of Deep Hole Making
Pull boring enables users to achieve remarkable straightness in deep holes. A variation of this technique is also effective when maintaining consistent wall thickness (in long, cast pipes, for example) is top priority.
