Precision toolholder run-out is under
0.003mm
A precision toolholder provides absolutely steady tool clamping with no shape distortion of the toolholder, giving a consistently precise run-out accuracy of less than 0.003mm.
Among toolholding innovations aunched by Schunk at EMO 2007 was an extension of the Tribos-RM precision toolholder range to accommodate an HSK-A 40 interface that is completely sealed This development ensures maximum tool life even in the most difficult environments whilst minimising maintenance costs

'Collet jaw' chucks offer greater versatility
A 'collet jaw' chuck is more universal than either three-jaw chucks or collets and covers a greater diameter range than conventional collets thus increasing flexibility and cost effectiveness.
Zero-point clamping system reduces work resetting
Universal zero-point clamping system that provides accurate and repeatable set-ups of workholding fixtures allows workpieces to be moved through multiple operations with minimum resetting.
Built for high-speed cutting at up to 60,000 rev/min, the Tribos-RM has a run-out accuracy of less than 0.003mm with high radial rigidity and excellent vibration dampening to provide astounding machining results, said Schunk.
In addition, the internal coolant supply protects tools and increases tool life.
This improved tooholder from the Tribos family is coolant-proof up to 80 bar and is capable of clamping tools in the 3-12mm diameter range.
The balancing grade is G2.5 at 25,000 rev/min.
Schunk also showed its Tribos-RM ISO toolholder for high performance micro machining.
Like the Tribos HSK-A 40, the new ISO toolholder is built for high spindle speeds of up to 60,000 rev/min with a balancing grade of G 2.5 at 25,000 rev/min.
Intended for micro machining the ISO range holds tools in the 1-6mm diameter range.
Separate laws apply for micro-machining said Schunk in a report to Manufacturingtalk.
That is why Schunk is offering the Tribos-RM precision toolholder with an ISO interface.
The one-piece rotationally symmetric design of the Tribos-RM ISO ensures the long tool life of the machine spindles and the complete transmission of power, said the company.
Compared with thermal tool clamping, the Tribos-RM offers absolutely steady tool clamping with no shape distortion of the toolholder.
This allows the end user to benefit from a consistently precise run-out accuracy of less than 0.003mm.
The Tribos polygonal clamping technology was patented and developed by Schunk in 1997, where the technology is based on the polygonal shape of the clamping bore.
If an exactly defined external force is actuating the toolholder at the clamping side, the clamping bore will deform.
The toolholder shank can then be introduced into a larger, circular bore.
After this force is removed, the clamping bore will obtain its initial shape and will clamp the tool shank.
Within seconds, the tool is changed using a hydraulic clamping device. Request a free brochure from Schunk Intec ...
