The Heat Shrink Tool Holder offers some substantial benefits when compared to standard HSK-63F tool holders. A Heat Shrink chuck creates a more uniform, rigid connection between the CNC machine and the tool resulting in less vibration and a noticeably smoother cut. Since there is no collet or collet nut on a heat shrink holder, those inherent tolerances are not compounded. Here are some of the major benefits:
– One piece tool holder with no additional parts (nut/collets)
– Extremely tight tolerance 0.003mm & balancing properties
– High clamping force (~10,000 lbs) and rigidity
– improved tolerance equates to improved finish quality and up to 30% longer tool life
– Slim design, ideal for 5-axis machines and tight routing conditions
Wondering how shrink fit tool holders work? The receiving end of the tool holder is heated with an electric heating induction machine.
This causes the steel body to expand, allowing for the insertion of the tool shank. Once the tool shank has been inserted the heating element is turned off allowing the steel to cool and “shrink” around the shank of the tool. To remove the tool, just repeat the process.
Because of the need for an induction heating element to change tools, this system not suitable for using solid carbide tools that have to be removed regularly for sharpening. However, using this with an insert tool or a diamond tool is the proverbial “no brainer” since we offer the mounting service for FREE when you purchase a Heat Shrink tool holder with any of our standard or custom insert tools or diamond tools.
This system is ideal for longer life tools like PCD and insert tools due to the fact you do not have to remove the tool from the tool holder to change out the knives. With PCD tooling, if you utilize our sharpening service you can send the tool in with tool holder intact, we will take care of the rest. Are you interested in maximizing the precision in your shop?
