OMG Right Angle Heads – Get the Spindle Where You Need It

by Bernard Martin

If you’ve ever wrestled with part orientation or lost hours resetting a fixture just to reach a tough machining angle, you already know the value of a good right-angle head. OMG’s TA and TA.CP series angle heads aren’t just good—they’re purpose-built to deliver rigidity, accuracy, and performance where traditional spindle access just isn’t possible.

OMG’ (Officine Meccaniche Golinelli) has built a reputation over 60 years for designing heads that perform under pressure. Their TA and TA.CP series offer a broad range of configurations with robust internal gearing, innovative backlash-free anti-rotation mechanisms, and options that integrate seamlessly into both large and compact machine tool environments.

TA Series: Heavy-Duty Versatility
with Unmatched Precision

OMG Heavy Duty Angle Heads

The TA Series is OMG’’s flagship line of right-angle heads, designed for everything from simple 90° machining to highly specialized multi-axis operations. These heads feature Gleason ground bevel gears and precision bearings, delivering torque and speed with zero compromise on accuracy. With over 110 base models—and nearly 4,000 variations when you factor in all the spindle types, lengths, and coolant options—it’s the most complete line of angle heads on the market today.

Whether you’re running a vertical machining center with an ATC, a traditional mill, or a motorized turret on a turning center, TA heads are engineered to handle it.

Key Specs:

• Max RPM: up to 10,000 RPM
• Spindle Configurations: Single-spindle, double-spindle, fixed 90°, adjustable ±90°
• Coolant Options: Through-spindle coolant (TSC) available
• Gearing: Heat-treated Gleason bevel gears
• Bearings: Precision bearing assemblies for rigidity and smooth rotation
• Back-End Shanks: DIN 69871, CAT, BT, HSK, and BBT

A big feature is OMG’s newly engineered anti-rotational system—an internal V-shaped torque arm pin that eliminates angular play, even under load. This means better finishes, tighter tolerances, and repeatability you can trust job after job.

TA.CP Series: Compact,
Lightweight, No-Compromise Performance

OMG TA.CP Series Light duty angle heads

Need right-angle capability on a smaller VMC or compact horizontal? Enter the TA.CP series. Designed specifically for machines with lower tool changer weight limits, these heads deliver the same OMG quality in a lighter package.

TA.CP angle heads use an aircraft-grade aluminum alloy body, reinforced with high-precision internal gearing and OMG’s same V-shaped anti-rotation system. Despite their light weight, they’re fully capable of drilling, tapping, and reaming—making them ideal for high-volume, cost-sensitive production.

TA.CP Series Highlights:

• Head Construction: Aerospace aluminum body with reduced weight
• Torque Arm: Lightweight and simplified, still compatible with Heavy Duty Stop-Blocks
• Gear Design: Ground Gleason gears, lubricated for life
• Back-End Shanks: DIN 69871, BT, BBT, CAT, and HSK
• Extended-Length Options: For deeper or offset applications
• Indexing: Optimized setup for faster machine integration

These angle heads are engineered for seamless compatibility with existing OMG modular tooling systems, meaning you can use TA.CP heads without needing to reconfigure your entire setup

Why It Matters
If you're serious about reducing part handling, improving surface finishes, and opening up new toolpath strategies, investing in a precision right-angle head can be a game-changer. OMG’s TA and TA.CP series let you add flexibility and precision without overloading your tool changer or compromising your spindle integrity.

Whether you’re retrofitting an older machine or outfitting a new high-speed center, OMG’s modularity and attention to detail ensure the right fit—and the right performance—for your application.
