Anyone who wants to use their resources sustainably is always looking for alternatives to flood lubrication. Now they need look no further than the new MaxiLock-S-DC turning tool holder, whose two internal holes ensure that the coolant is applied precisely to the cutting edge. One hole targets the rake face from above and the other the flank from below – applying to the cutting edges precisely. In this case, not all good things come from above. By contrast, flank cooling boosts the service life by 60% compared with cooling exclusively on the rake face.
Tool holders with DirectCooling (DC) are equipped with two inner holes that guide the coolant to where it has the greatest impact: directly at the cutting edge. One hole targets the rake face from above and the other the flank from below. Why is this so important? Targeted cooling improves both the service life and general process security.
The lengths of all DirectCooling holders are ideally matched to one another. As a result...
Indexable insert: CCMT 120408EN-M55 CTPM125
Material: 1.4301 – X5CrNi18-10
Cutting data: vc 200 m/min | f 0.25 mm/U | ap 2 mm
What's interesting here is that the lower coolant hole on the flank of the indexable insert has a considerable influence on the tool life. While cooling exclusively through the upper two nozzles gives rise to an improvement of just 22%, flank cooling achieves an increase of 54% compared with standard cooling!
