TH SERIES

Alberti TH Series

Control Series angle heads are designed to be used on machining centers equipped with automatic tool changers. The orientation ring and the arrester arm, which carries the arrester pin, can both be rotated through 360°. This allows easy adjustment of the drive taper relative to a stop block mounted on the machining center spindle housing.

The TH series features 1500 psi. When used with an internal coolant the TH series can reach a higher RPM. The offset design of the Angle Heads offer an increased tool clearance.

hi pressure TH series Advantages

HI PRESSURE OFFSET HEADS

The offset angle heads series features a combination of high pressure coolant through the main spindle, up to 100 bar, and a high speed option.

GS 600 TOOL BODY

Increased thermal stability and rigidity compared to materials such as steel and aluminum. Bearing housing surfaces are completely ground.

GEARS

Gears are made out of special hardened super alloy. They are completely ground and treated with isotropic polishing that results in a dramatic reduction of vibrations and friction.

MECHANICAL SEALS

Special composition low friction seals reduce heat build up and keep contaminants out. High pressure rotary joint allows up to 100 Bar Coolant Pressure.

POSSIBILITY OF DRY RUNNING

A new feature of this series is the possibility of dry running during machining. This offers tremendous flexibility to ever changing applications.

SOLID OUTPUT SPINDLE

Solid piece spindle made out of hardened steel to increase resistance to bending stress by up to 25%. Achieve higher RPM without vibrations.

MONOLITHIC FLANGE ARM

One piece flange arm and pins grants increased rigidity and stability to the whole structure while machining. Ultra precise pitch dimension.

BEARINGS

Super precise ABEC 7 and 9 Class Bearings. They ensure perfect concentricity and stability during machining.
