- Superior Concentricity - The concentricity of Shrink Fit Tooling is guaranteed .0002 or better with the cutting tool set in the shrunk condition.
- Superior Balance - All Shrink Fit Tools are manufactured for high speed operation. Shrink Fit tools are dynamically balanced to G 2.5 at 20,000 RPM’s. This results in balanced chip loads, better finishes, and increased speeds and feed rates. With no set screws and no moving parts the toolholder remains in balance leaving the cutting tool as the only variable.
- Superior Rigidity - The average gripping force imposed on the shank of the cutting tool is 10,000 lbs. This force far exceeds any collet, milling, or hydraulic chuck by more than 5 times. The average machine has less than 6,000 lbs of force on the retention knob holding the toolholder in the machine. It would take over 100 horsepower in order to turn the tool within the bore of the toolholder. An additional advantage is the shank of the tool is gripped 360 degrees the entire length of the bore. This is not the case with milling chucks and hydraulic chucks. These chucks leave an area of up to ¼ inch from the end of the toolholder with no force applied to the tool shank. Using the Shrinker gives you the closest possible rigidity to an Integral Shank Tool with lower costs and more flexibility.
- Superior Tool Life - The "Shrinker" Toolholding System extends tool life up to 100% or more. With the superior holding force, concentricity, and balance, the chip load is evenly distributed on the cutting edge. The rigidity established with the Shrinker enables cutting tool technology to be pushed to the maximum.
- Superior High Speed Operation - The Shrinker is the superior toolholding system for high speed machining. In extreme high speed operations centrifugal force becomes an important factor in desired speeds and feed rates. With the holding force induced by the "Shrinker" system being superior, no other system can meet and maintain the clamping force. The Shrinker System is a must in extreme high speed applications and is superior at any speed. A very important feature of Balanced Shrinker Tooling is the extended spindle life. Spindle life is greatly increased with superior balance and rigidity the Shrinker offers.
- Superior Operating Parameters - The Shrinker System provides the best operating advantage of any holding system. No holding system offers shorter extension length capability with concentricity of .0002 or less. Milling and hydraulic chucks offer excellent concentricity, but the mechanical clamping system requires additional extension and sacrifices rigidity. Conventional End Mill Holders can provide very short extension lengths, but sacrifice concentricity and provide 2 or 3 point clamping. The thin profile required for the Shrinker enables the operations to be performed with less interference. Tooling can be preset by simply controlling the depth the shank extends into the bore.
- Simple Operation - The Shrinker System is truly the easiest system to use. The induction tool changer is by far the fastest and simplest method to change tooling. The average induction cycle takes 7 seconds to expand the bore enabling the operator to remove the dull tool and insert the new tool. Seconds after the new tool is inserted the bore shrinks back and can be placed in a cooling block to aid in drawing the heat away from the holder. This entire procedure takes less than 30 seconds. No wrenches to find, no vises required, uniform chucking without torque wrenches, and faster than any conventional clamping method.
- Conclusion - The Shrinker Thermo Contraction Toolholding System is by far the most economical system in the world today. The increased productivity provided by using the most rigid holding method can be measured every day and multiplied by the total manufacturing days in the year. If that wasn’t enough, the increased tool life can be measured, multiplied, and added to the increased productivity. Additionally, the accessory items used in day to day manufacturing and reduced down time required to change tools will contribute to the considerable reduction in tool costs. Most cost saving programs require some sacrifice to achieve the savings. Not the Shrinker, you can achieve the true savings with the Shrinker, and in return you get the most rigid toolholding system available.
