Optimally formed shank end!<br />
For a secure <strong>MQL</strong> delivery<br />
Flow pattern with low vortex formation<br />
the delivery of these extremely low coolant quantities directly<br />
to the effective area is of utmost importance. Hereby, the<br />
geometric design of the shank end plays a significant role!<br />
the guhring developed conical shank end optimally satisfies<br />
the relevant <strong>MQL</strong> conditions.<br />
Advantages of the tapered shank end:<br />
• no lubricant delays<br />
• minimal dead area<br />
• simple operation<br />
• cost-efficient production<br />
Flow conditions in the coolant<br />
duct connection slot at the<br />
point of the tapered transition<br />
Keeping a cool point<br />
With <strong>MQL</strong> the process temperature can be considerably<br />
reduced in comparison to dry machining resulting in longer<br />
tool life and an increased process reliability.<br />
