1. Spheroidal Cast Iron.
Greatest absorption of vibrations, low thermal expansion, very good dimensional stability, high tensile strength.
2. Solid main input shaft (one integral piece with the drive taper) case hardened and ground.
Better rigidity, resistance to stress and power output.
3. Shafts supported by sets of super precision pre-loaded angular contact bearings with Long Life grease lubrication and ABEC 7 accuracy rating.
This location of bearings gives a great rigidity to the head allowing the shafts to extend following the increase in temperature without loosing rigidity and damaging the pre-load of the bearings.
4. Spiral bevel gears in a higher performance materials with a strength in excess of 300 kg/mm2 used in the F1 racing, aerospace and military fields.
Concentration of high power capacity within a confined space.
5. Computerized computation of the data of the set gears.
In order to have more than one tooth working during mesh so that more power can be transmitted and longer gears life, better meshing of the teeth during rotation and, as a consequence, almost no noise.
6. More than 40 Angular Heads types
availabe. Widest range of applications on machines and work-pieces with particular overall dimensions and shapes.
7. New types of Angular Heads with reduced weights and overall dimensions.
The smallest type able to enter a hole of only 30mm, while the huge one able to give a 250 Nm output power.
8. Double seal on the front (mechanical seal+gasket). Better protection of seals and internal parts from coolant infiltration in order to increase the Angle Head working life.
9. Coolant feed through the collet chuck (option). For specific applications which require it such as: working operation from 10 upto 70 bar (dry or wet running).
10. Coolant feed through the spindle (option).
For specific applications which require it such as: working operation upto 10 bar (dry or wet running).
11. Ceramic ball bearings, special seals and balancing of each part and component (optional).
In order to reach High speed ratio upto 12000 rpm.
12. Aerospace external finishing.
Reduced weights and overall dimensions.

Features
In spite of the small body diameter, high output power is achieved.
The outer housing is made of stainless steel(SUS416) with a high-accuracy,ground finish(0/-0.01mm)
No heat is generated for long continuous use due to air driven operation.
By mounting a silencer on the back-air tubing, the quiet operation of air turbine is remarkably improved.

The retrofitting options in particular mean that the possible uses of our geared motor spindles are diverse. Most applications are in the following areas:
- Milling
- Turning
- Special applications
We are currently offering an undisputed technological lead in geared motor spindles for turning and milling at high torques. Geared motor spindles for milling are primarily used for heavy-duty machining, the machining of titanium and in shipbuilding.
Geared spindles have smaller rotating masses compared to existing assemblies with an external drive and run more quietly and with less vibration. Comparatively good machining standards are achieved for planing. While maintaining the radial dimensions and motor performance, the usable torque of the motor can be increased 4-fold. This allows considerable expansion of the machining range of a machine, particularly for rough-machining, i.e. more machining tasks can be performed with different cutting speeds (different materials) with small and larger tools.
