Shrinking 5.5.2.1 Special shrinking: Inverse shrinking (shrinking from the bottom) This function is only available with an option “change coil“. ISG3410 with an option “change coil” enables the shrinking of tools inversely where the cutting edge diameter is larger than the coil diameter and would therefore not go through the coil during a conventional shrinking process. For this purpose, it is required that you’ll need a special slim tool holder, a coil limit stop (ISGF3414, page 49) and a special coil (ISGS3200-3.1, page 50) without a ferrite disc. The operation inverse shrinking can be selected with the option Invers. 5.5.2.2 Inverse shrinking-in In order to shrink-in a tool, choose the function “Inverse shrinking” in the menu Special. For ISG3410-WK the coil moves automatically to the lower end position of the cylinder. Now put the clamping chuck into the tool holder and position it in the coil. Take care that the tool holder with the chuck is positioned in the centre of the coil. Place the coil limit stop at the lift cylinder above the coil (see Fig. 10, page 31). Push up the coil manually, until it is placed in shrinking position to the chuck. The coil is in the correct position if the ferrite disc nut is on a level with the front side of the chuck. Now position the coil limit stop so that the coil will stop at that position when going in the automatic mode. Proceed as described under item 5.2.2 Clamping, page 20 There is no suitable cooling fixture for ISG3410-TLK unit for the slim tool holder. Therefore, the clamping chuck cannot be cooled down in the conventional manner on a cooling station. Take the tool with the tool holder out of the coil, when the coil has retracted. Put both on a heat resistant mat and prevent people from touching the tool and the hot chuck accidentally. 5.5.2.3 Inverse shrinking-out In order to shrink-out a tool, put the chuck in the suitable tool holder with the unit switched on and the operation “Inverse shrinking” selected. (The coil is located in the lower end position of the cylinder). Proceed as described in the Chapter 5.5.2.2, Inverse shrinking-in. Assist the detaching of the tool by pulling the tool gently. Take the tool with the tool holder out of the coil, when the coil has retracted. Put both on a heat resistant mat and prevent people from touching the tool and the hot chuck accidentally.
