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.

Tool-changeable NC axes for machining centres:
The freely programmable KomTronic® U-Axis system make any contour and turning operations possible on non-rotationally symmetrical parts.
Combined with custom-made front tools and the optimum selection of inserts, contours in bores and external machining operations can be successfully carried out. This allows a considerable reduction in production times, with better surface quality and greater accuracy of form.
Further savings in time and costs can also be achieved by reducing the number of tools previously required - for example, circular milling a complex internal contour with various form milling tools. The saving in form milling tools and tool changes this achieves also reduces production time and production costs.
Greatly reduced processing times and higher precision
KomTronic® U-Axis systems essentially consist of one compact facing head with single slide that is driven by a servo motor and threaded spindle. The power supplied to the electronics and the drive is transmitted contactfree and inductively to the U-Axis system. Similarly, the data is exchanged inductively with the U-Axis system.

Reduce overall machining time for many applications!
BENZ multi spindle heads are the only possibility to increase production volume and lower the price per unit produced at the same time.
BENZ Multi Spindle Heads are modular in design, which makes it possible to reduce outer dimensions and weight to a minimum. This means, even machines with limited room and weight capacity in the tool changer, can be equipped with multi spindle heads. A high degree of component standardization enables us to build many different spindle configurations within a short time frame.

U-TRONIC
U-TRONIC offers a range of medium and large NC heads, controlled by the U axis of the CNC for inner and outer facing, back-facing, cylindrical and conical boring, threading, concave and convex radius machining and complex profiles, by the interpolation with the other machine axes. These heads can be fitted manually, automatically or through palletised systems, on boring machines and specialty machines.
They are available in eight standard models, between 180 and 1000 mm diameter, all of them with internal coolant supply. U-TRONIC heads are supplied in special double tool slides versions or with counterweights for tool slide self-balancing.

U-CENTER
U-CENTER are servo controlled heads for machining centres and specialized machines. Controlled by the U axis of the CNC,.the U-CENTER can perform facing and back-facing, cylindrical and conical boring, threading, concave and convex radius machining and complex profiles, by the interpolation of the other machine axes. The servo driven gear box is mounted next to the spindle of the machining centre and the control, guarantees the control of the tool slide feed and the tool position. The U-DRIVE is composed of: a servomotor, a transducer, a set of limit switches and a coupling system for the U-CENTER head. The heads are available in 4 models: UC140/BH - UC160/BH - UC180/BH - UC200/BH, all of them with internal coolant supply and counterweights for balancing.
