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.
Tilting heads for milling with possible inclination of ± 92°.
6 different models complete of electrospindles with capacity from 3 KW up to 56 KW.
All models are equipped with a high efficiency hydraulic clamping system and high resolution encoders direct mounted in axis assuring perfect positioning and absolute repeatability.
The heads can also be supplied fitted for electrospindles of your choice.
Our technical department is at your disposal for personalized studies in order to make the installation on your machine tool easier.
Technological performance of TOS VARNSDORF machines may be considerably expanded by the use of special technological accessories such as facing heads, milling heads of various type, automatic tool change and automatic pallets change. The producer offers also a remote diagnostics between the customer’s machine and remote diagnostics workstation.
