Shrink fit tool holder design

In high-speed applications a second look at toolholder selection can yield machining benefits often not realized at first glance. Shrink-fit in the recent past was often thought of as the toolholder of choice for high-speed applications requiring accuracy. However, an in-depth look at the many hidden benefits of a quality high-speed collet toolholder reveals many advantages over the shrink-fit tooling for most high-speed applications.

High-Speed Collet System One of the benefits realized from a high-speed collet system is vibration dampening. There are several characteristics that contribute to the vibration dampening including the collet itself absorbing and isolating vibration.

Also, the density of the material in the body of the collet toolholder being greater than a shrink-fit toolholder accounts for a portion of the vibration dampening. Shrink-Fit Tooling The vibrations seen in the shrink-fit tooling can lead to fretting on the tool and the toolholder. Other shrink-fit tooling disadvantages include a large investment of money and space for the machine to heat up the toolholders; and, the material needed to be used to expand and contract to accept the tool is not the optimal material to use for a toolholder taper.

The problem lies in maintaining the integrity and accuracy of the spindle taper long-term. It is this spindle taper that determines a great deal of the accuracy of the toolholder.

A good high-speed collet toolholder system also offers the same slim and smooth profile that shrink-fit tooling does. These systems also reduce the air current vibrations by utilizing a nut that is ground smooth with no hex flats or slots for wrenches. Quality Guaranteed.

This results in an extremely high gripping torque that prevents any irregular movement of the cutting tool during roughing or finishing operations. This, in turn, results in the reduction of scrapped pieces. Their concentricity, gripping force, and balance help you increase productivity and ultimately extend tool life by a wide margin.

Do you want a long lasting tool? Shrink fit tooling technology is the best for your needs. Shrink fit tooling is the go-to for any high-speed machining operations. Their clamping force along with their superior system makes them the best choice for any high-speed machining operations.

Unlike mill and hydraulic chucks, shrink fit tooling offers extraordinary concentricity, making it outperform other brands in the market. Superb accuracy. High gripping torque. Extension outlets that offer you diverse options with standard products. Reduction in tool-changing time. This, in turn, leads to greater productivity. Setup cleanliness, leading to cleaner bores and less contamination.

This is because shrink fit tooling is a sealed system. Outstanding coolant options, which both aid in cooling and in delivering fine finishing.

Cost reduction. The cost of tool changing is far lower if you use shrink fit tooling systems.
