How to Achieve The Desired Results in Turning

In many cases, internal Turning operations can be a very complicated and challenging operation. Choosing the right tool and insert shape can turn the bowl upside down and we can enjoy safe and soft machining.

The length of the tool has great importance. and is usually determined by the depth of work required.
The greater the tool overhang, the chance of flexibility and vibration increases drastically. As we know, vibration can cause significant damage to our workpiece, especially to the surface quality.
Select the tool according to the machining length and Diameter to Length Ratio:
- For short overhang of up to 4-times bar diameter, please use ISCAR’s standard steel bar shanks.

- For a higher overhang of up to 7 Times Bar diameter, please use ISCAR’s standard solid carbide shanks. Solid carbide has good restraint properties and can prevent and reduce vibrations.

- For a higher overhang of 7 Times Bar Diameter up to 14 bar diameters, please use ISCAR’s standard Whisper line with the dampening mechanism.

The importance of chipformers in internal operations:

Breaking the chip has great importance in internal machining, once we choose the right length, it’s time to choose the best and correct chip former.
Splitting the chips into small segments will ensure good surface quality, more accuracy and better insert life. Use High-pressure cooling directly to the cutting zone to ensure better chip evacuation.
