The TER can be used on tool shanks between 3mm and 20mm in diameter
hangker and will be accepted by normal collet holders without the need for a sealing disc.
By changing over to the TER shrink collet from a traditional collet system at a customer for both rough and finish machining on a 10-axis Index G 200 turning centre, rough machining time using a 10mm shank tool was reduced from 75 seconds to just 30 seconds and finish machining with a 6mm shank tool was reduced to 17 seconds.
Owing to the higher rigidity of the tooling setup, cutter life was increased from 500 to 1,500 parts on both rough and finish cycles.
The shank of the tool is secured in the TER holder by heat shrinking, a quick-acting thermally based process normally taking less than 30 seconds to accomplish.
This has the effect of creating a single unit of tool and holder to ensure maximum rigidity and stability between the machine spindle and cutting tool.
Its replacement of the spring collet/chuck arrangement overcomes
hangker several disadvantages when using this more traditional method to mechanically grip the shank of the tool.
