Problem free machining with high pressure coolant In recent years, much attention has been paid to the development of high pressure coolant systems. This technology can have dramatic effect on productivity and process optimization. Especially when coupled with tooling designed to maximize its effectiveness. In this episode we will focus on the effect optimized tools have on chip breaking on chip breaking in turning applications in super alloys. With this animation we can see a traditional approach to turning this often results in long, stringy chips that really reduce machine utilization. In turning the cutting edge is in constant contact with the work piece and therefore generates a lot of heat. With a conventional system instant evaporation takes place. This is caused by the insufficient direction and focus of the coolant. So how do we solve this problem? High pressure coolant at a pressure of up to 80 bars/1160 psi, combined with the nozzle technology in Coroturn HP really provides a mean to vastly improve chip control. The key to success is the high precision nozzles mounted on the tool. These predirected nozzles offer precision of the coolant, and it targets the right place at the right angle. Performance and security is really built in and guaranteed. Let’s take a closer look at the effect of the high velocity jet stream caused by the nozzles. When the coolant is targeted directly at the cutting zone it produces a hydraulic wedge between chip and insert. This wedge lifts and curls the chips, breaking them in to small pieces as they form. In summary, using optimized tools with fixed nozzles in combination with High Pressure Coolant has a dramatic effect on machining security. Less chip entanglement, machine stoppages to clear chips and operator supervision is reduced. Here we have only talked about one effect of using high pressure coolant. There are many other benefits. Increased productivity achieved by increasing the cutting speed. Increased tool life achieved by cooling the cutting zone. Improved process security achieved by better chip control, and all this results in improved component quality and cost reduction. An optimized system with high pressure coolant can pay for it self in just a few months. For more SMART tips contact one of our specialists or visit us at the Sandvik Coromant web site.
