Unisig USC-M drilling and machining center

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.

Unisig Durable Tooling Guide

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.

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.

UNISIG’s New B850 Introduces Technology Advances in Company’s B-Series Machines

UNISIG has unveiled newly developed technologies that substantially improve performance while reducing cost in its larger B-series machines. These advances are introduced in the newly launched B850 model and will be integrated into larger models in the series.

When designing the B850, UNISIG evaluated all aspects of the previous designs. The bed and rack-and-pinion system were retained, while feed systems were modernized to improve rigidity and reduce backlash. A new high-performance, helical-geared transmission was incorporated in a three-range, automatically shifting headstock. Incorporation of modern gearing and power train concepts simplified construction of the machine, reducing cost and boosting reliability and performance.

The B850 also offers a standard programmable coolant system. Combined with user-friendly controls and the other new design features, the machine allows an operator to focus on the part being machined instead of managing a wide variety of manual functions.

Both the work and tool headstocks deliver 166 hp, providing the high power and torque needed to drill holes up to 7.1” (180 mm) in nickel alloys, 8.7” (221 mm) in carbon steel, and 12.6” (320 mm) with counterboring. The B850 model is available with maximum drill depths ranging from 78” to 65’ (1.98 m to 19.81 m), and the machine bed can accommodate workpieces up to 10 tons (9,071 kg).

The B850 is part of UNISIG’s extensive B-series line, designed for on-center drilling of round workpieces in applications such as aerospace, defense, and oil & gas. In addition to standard BTA drilling methods, these machines are also capable of counterboring, trepanning, and skiving and roller burnishing processes, achieving the extremely strict tolerances required by manufacturers in these and other industries.

As with all of its equipment, UNISIG engineers and manufactures the B-series in the United States with high-performance components. The company’s full portfolio of machines are capable of producing holes with diameters ranging from 0.004" to 19.69" (1 mm to 500 mm) at depths ranging from 0.787" to 787.4" (20 mm to 20 m). Machines are provided with all necessary durable tooling and machine accessories. UNISIG provides comprehensive training for machine operation and process optimization, as well as post-installation technical support.
