TRIBOS-SVL

Unsurpassed, slim design

The TRIBOS-S toolholder provides optimum conditions for machining tasks in or at workpiece areas, which require extremely low tool clearance. By using the very slim TRIBOS SVL extensions, standard cutting tools can often be used.
The use of expensive special tools with long deliveries are history.
The concentricity of less than 0.003 mm is guaranteed.

TRIBOS tool extension SVL when using a TENDO Hydraulic Expansion Toolholder

Can be used in many areas

Tool extensions can be combined with various toolholders.
- with Hydraulic Expansion Holders
- with Heatshrink Holders
- with other Precision Holders
and, of course, with TRIBOS toolholders.

Synergy effect

TRIBOS extensions in conjunction with our TENDO Hydraulic Toolholders or our TRIBOS-R Polygonal Toolholders complement each other in an ideal way. Both systems have a damping effect on the complete system and reduce tool vibrations.

High run out accuracy and repeatability

Maximum continuous run out accuracy of less than 0.003 mm.

The advantages:

		Uniform cutting results
		A 4 times higher tool life is not uncommon
		Process safety during tool change
		Optimum machining results
		Lower wear of tools
		Smoother running
		Protection of machine spindle
		High dimensional accuracy and machining quality

*Compared to all other (production specific) mountings

HSC suitable

The TRIBOS Polygonal Clamping Technology was tested at the PTW, the Institute for Production Management, Technology and Machine Tools at the Technical University of Darmstadt by means of centrifugal tests up to 205 000 rpm. The clamping force on the clamped trial bolt was retained throughout the complete speed range.
The TRIBOS Polygonal Clamping System is approved for TRIBOS-R and TRIBOS-RM up to 55 000 rpm and for the TRIBOS-S and TRIBOS-SVL up to 85 000 rpm.

TRIBOS toolholders are precision-balanced as standard.

Clamping process in less than 20 sec.

A tool change can be carried out in less than 20 seconds.
No heating, respectively cooling processes are required.

Clamping devices

No moving parts – absolutely maintenance-free

There are no moving parts in the TRIBOS Polygonal Clamping System, consequently it is mechanically insensitive providing absolutely wear-free clamping.
The TRIBOS Polygonal Clamping System clamps tools by means of the residual tension of steel without any moving parts in the toolholder. It is thus insensitive to contamination and absolutely maintenance-free.

The flexible solution through the use of intermediate sleeves

By means of slotted intermediate sleeves, several shanks diameters can be clamped with one TRIBOS holder. This makes your toolholder flexible and saves money. The concentricity of the sleeve is less than 0.002 mm.

Intermediate sleeves GZB-S

Everything can be clamped

Carbide as well as HSS tools can be clamped in the same toolholder. Shanks with Weldon or whistle-notch can also be clamped. The best clamping results are achieved with totally straight shanks with an h6 tolerance.

Axial length adjustment

The clamping movement of the TRIBOS Polygonal Clamping Technology only arises in a radial direction, consequently no axial movement is present during the clamping process.
A precise axial length adjustment (< 0.01 mm) is possible.

Length Measuring System LMV 360

Absolutely rotation symmetrical design – basic imbalance less than 4 gmm

Due to the optimum concentricity of the totally symmetrical design, the TRIBOS toolholder offers ideal conditions for highest machining speeds with high balance requirements.
All TRIBOS toolholders are fine-balanced as standard for use on HSC machines.

Perfectly suited for use with MMS (minimum amount lubrication)

MMS is a dosing technology system which reduces the amount of lubricant used to a minimum. The amount of lubricant is either fed to the point of application directly or nebulised into a fine spray and then fed to the point of application. The design and assembly of the components inside or outside of the toolholder are similar to those of a nozzle system.

MMS is a loss- or consumption lubrication, which means that the used medium is nearly completely vaporised. The vaporisation and the pressurised air stream also cool the workpiece.

In the area of MMS, SCHUNK works in close cooperation with well-known partners. The aim is to standardise the individual interface components in a joint effort.

If the customer requires it, and once all details have been settled, the SCHUNK toolholders can be re-equipped for MMS operation.
