New surfacing option for digitising software
The latest version of Tracecut, Renishaw's market leading digitising software, features a new optional surfacing module which will create true CAD surfaces suitable for export to any CAD system
Using Renishaw's novel 'ToolWise' technology, tools as small as 0.2 mm diameter (depending on the tool surface finish, machine environment and installation) can be checked at 300mm range.
Tools typically spend 1s in the laser beam, so the TRS2 is also suitable for use in high volume production environments and for low, medium and high speed spindle machines.
Comprising a single compact unit containing the laser source and detection electronics, the TRS2 is easy to install and can be mounted outside the machine's working envelope, saving valuable table space and also being safe from the risk of collision.

Set-up is also simple with dedicated Renishaw software.
Tools can be detected at distances of between 0.3m and 2.0m, depending on a tool's surface finish, machine environment and installation.
The TRS2 is suitable for a wide range of machines, although it is optimised for use at distances of up to 1.0m.
The Renishaw TRS2 is a replacement for the original TRS1 unit, which has been successfully installed on machines worldwide.
With enhancements made to Renishaw's ToolWise technology, the TRS2 benefits from improved tool detection reliability and reduced cycle times.
* Greater spindle speeds - key benefit of this enhancement is the ability to work at a greater range of spindle speeds, (200, 1000 and 5000 rev/min) enabling the detection of a larger number of tool types in a wider range of applications.
For instance, gun drill applications are now possible and for high speed spindle machines, valuable time waiting for spindle deceleration is minimised.
The detection of small, dark tools is now more reliable, and the TRS2 can detect a wider range of solid centre tools including drills, taps, end mills, slot drills and ball nose end mills.
Conventional non-contact broken tool detection systems depend on the laser beam being blocked (tool OK) or not blocked (tool broken).
The TRS2 is different, using the unique tool recognition electronics within the ToolWise technology to determine whether a tool is present by analysing the reflected light pattern from the rotating tool.
Random light patterns created by coolant and metal chips are ignored, reducing the chance of not detecting a broken tool due to coolant blocking the beam. Request a free brochure from Renishaw ...
