The concept is simple. Each Shrinker tool holder is manufactured with an inside diameter slightly smaller than the shank diameter of the cutting tool. A heat induction unit is used to quickly heat the holder end of the Shrinker, expanding this inside diameter. At this point, the tool shank slips easily into the holder.
What are shrink fit holders?
A shrink fit tool holder is designed to secure cutting tools used in high-speed milling machines. Rather than using a set screw or collet chuck to grip an end mill, the shrink fit variation uses the heating and cooling properties of metal. ... As the metal holder is heated, it expands, allowing to tool to fit in.
What are two advantages of using a shrink fit tool holder?
No other clamping system can match the grip, concentricity, and performance of a shrink fit interface. Also because shrink fit tool holders do not need any collets, collet nuts, or set screws nose diameters can be very slim allowing you to machine hard to reach areas.
How do I select a tool holder?
The most important requirements for a toolholder are the gripping force at high speeds as well as the run-out accuracy and balancing quality, which reduce vibrations. Toolholders need to have a run-out accuracy of less than 0.003 mm.Dec 1, 2007
How do I identify a tool holder?

"Tool holder" is a general term for the adapters used to mount the cutting tools in the machine-tool equipment that performs these operations. Tool holders influence the machining accuracy of machine tools and even product quality, so they demand high precision for which not even microscopic error is permitted.
What are the tool holders used in machining?
Tool Holder Types Machine arbors are motor-driven shafts that turn machine tools. Blank adapters can be customized for specific applications or machining tasks. Boring heads can hold a variety of cutting tools, but are used mainly with boring bars. Collet chucks use collets of various sizes to hold machine tools.
What are the tool holders in CNC?
A toolholder is a device that safely provides a critical interface between the cutting tool and the spindle of the CNC machine. The cutting tool is mounted into the holder and is tightened so it does not move or vibrate during machining; providing the stability you need to ensure precision cuts every time.
What is tool holder in lathe machine?
CNC lathe tool holders are machining components that hold the lathe tool firmly in place during operation. Your choice of lathe tool holder depends on the accuracy and speed of cutting you require, with different tool holders having different levels of balance and runout.Aug 18, 2020
What is the function of a tool post?
Tool posts are used to hold cutting tools. Tool posts allow for rapid tool changeover and provide a high degree of position repeatability and indexing.
