Bonding on the tip of the blade, increasing the build-up edge, increasing the wear of the cutting tool. The high temperature and strong friction between the rake face of the tool and the chip, together with the poor anti-adhesion performance of the cutting fluid, results in an abnormal increase of the built-up edge and a fracture. Blade damage and exfoliation lead to increased tool wear (1) Replace with active oil-based cutting fluid (2) Check cutting fluid activity. If activity is reduced, active extreme pressure additive (3) should be added to replace water-based cutting fluid with active extreme pressure additive. Cutting Oil (4) Recommended NC300, NC400, NC500, NC500A
Cutting zone temperature is too high, resulting in softening, melting of the tip, discoloration of the cutting chip, resulting in reduced tool durability. Insufficient cooling of the tip part (1) Change the oil-based cutting fluid to water-based cutting fluid (2) Increase the liquid supply and supply pressure (3) Control the temperature of the cutting fluid. If the temperature rises too high, increase the volume of the cutting fluid tank or take measures to reduce the temperature.

The tool grinding interval is getting shorter and shorter (1) The cutting fluid is caused by the lubricating oil or hydraulic oil of the lubrication system mixed in. The additive content is reduced (2) For water-based cutting fluids, only make-up water is added, and the original fluid is not added proportionately, resulting in a decrease in the concentration of the cutting fluid (1) Replace with a new fluid (2) Additive additive (3) Take measures to prevent oil leakage (4) Check the concentration of the cutting fluid and supplement the original fluid (5) Recommended SCC638 SCC103 *The above recommendations are for reference only, if the actual application conditions can be provided by our sales engineers or technical customer service more suitable products or comprehensive solutions Fault content Causes Causes Solution Tool chipping and damage Thermal shock due to broken cooling , Lead to tool chipping and damage (1) Improve the liquid supply method, expand the liquid supply range (2) Change the cutting fluid with poor cooling (cutting oil)
