High pressure coolant machining for better productivity and resultsINDONESIAJakarta:

247PARTING pressure coolant can provide the following benefits especially in challenging workpiece materials :• higher machining security, • consistent machining process, • fewer machine stoppages,• better component quality,• shorter machining times,• better utilization of machine capabilities.These benefits can be applied to external and internal turning, milling and drilling through CoroTurn® HP, CoroMill® and CoroDrill® concepts.What does high pressure coolant application contribute to machining?When to apply high pressure coolant? 3What is high pressure coolant? 4How is high pressure...

3 Defined role for coolants The application of coolants in machining is undergoing somewhat of a re-evaluation. Many machine shops have used coolant in a conventional way, directing a tube which floods the machining zone. Today, some machine shops question the use of coolant altogether and introduce dry turning. Some use it only to control dust, chip evacuation or for finishing to achieve required surface quality and tolerance. Strategic use of coolants Just flooding the machining zone with coolant is not enough any more. If coolants are to be applied effectively they need to be applied...

4 í = CD × × ð d2 4 ñ × ã 2p n What is high pressure coolant? Pressure, flow rate and coolant nozzle High pressure coolant is more than pressure, it is coolant flow rate and coolant outlet size in the system, from pump to tool. The principle behind the application of high pressure coolant is that a reduction in the fluid outlet (nozzle on toolholder) produces an increase in the fluid velocity coming out of the nozzle. The larger the nozzle, the higher the flow rate of the fluid has to be in the tube and vice versa. Moreover, the number of nozzles (accumulated outlet area) will affect the...

5 Key values for high pressure machining In turning, the nozzle size recommended to produce a CoroTurn HP precision coolant jet with laminar flow is 1 mm diameter. A flow rate of at least 20 litres per minute is recommended. Exchangeable nozzles with outlet holes are available between 0.6 to 1.4 mm. The coolant pressure recommended for optimum CoroTurn HP turning, as well as for CoroMill milling and CoroDrill drilling, for high performance and results in most workpiece materials is 80 bar (1160 psi). For each 1 mm nozzle being employed in the tool, a coolant flow-rate of 5 litres per minute...

6 How is high pressure coolant applied? CoroTurn® HP …. ….. is a standard concept for external and internal turning of especially demanding materials with high pressure coolant. It is suited for application on lathes, multi-task machines, vertical turning machines and turning centres. The toolholder is equipped with two to three nozzles positioned and directed depending upon the tool type and the application it is intended for. It will connect to the machine tool or extra pump equipment for supplying coolant at pressure needed, ideally at 80 bars. This supply is widely available and...

7 Fixed coolant-nozzle technology The high pressure coolant application by way of CoroTurn® HP is based on carefully developed nozzle technolgy based on decades of experience. Optimized nozzles give parallel laminar jets of coolant with high velocity accurately directed at the right place on the insert. The precision and character of these jets make the difference. CoroTurn® HP has fixed, pre-directed, high precison nozzles mounted on the tool targeting the right place, at the right angle on the cutting edge. No setting with trials are needed, performance and security is built in with only...

8 Internal turning Operations, such as straight boring, profiling, grooving or pocketing, are characterized by being the most challenging as regards applying the coolant optimally, achieving suitable chips and evacuating chips safely and efficiently. For high pressure coolant applications there are a number of CoroTurn HP solutions that provide the benefits for internal machining – whatever the depth of hole. The CoroTurn SL 32 and 40 boring bars with a round serrated lock coupling between boring bar and cutting head provide high pressure coolant machining for a large range of internal...

9 Grooving, profiling and pocketing The typical, common geometrical features that occur in many aerospace and power related components make demands on accessibility in external and internal confined spaces. This background has formed the basis for developing the CoroTurn SL70 concept for grooving, pocketing and profiling with the aid of high pressure coolant. An oval, serrated-face type coupling - between the modular tooling adaptor and the actual tool-blade holding the indexable insert - fulfills the requirements for stability and accuracy at long tool reach. The range of SL70 blades in...
