TetraMini-Cut – cylinder liner – AH8005
IMPROVE PRODUCTIVITY AND TOOL LIFE
In external grooving of 40Cr cylinder liners on a CNC lathe, the previous solution faced frequent insert changes due to short tool life and persistent chip entanglement.
By introducing Tungaloy's TetraMini-Cut with grade AH8005, featuring stable chip control and superior wear resistance tailored for steel parts, the customer achieved a dramatic improvement.
Tool life nearly doubled, with parts per cutting edge increasing from 230 to 450, while productivity also rose by 20%, enabling smoother, more reliable machining.
