High pressure coolant avoids early tool
failure
Cutting fluids pumped to 70 bar or more, and accurately directed at the cutting zone, will force swarf away from the cutting area especially in deep hole drilling or pocketing routines.
Flood coolant systems on many machining centres and multi-axis CNC lathes will only deliver cutting fluids at fairly low pressure, typically around 5 bar While they look like they are doing a good job by drenching the workpiece, the fluid can boil away or vaporise before penetrating the critical high temperature cutting area and so machining efficiency suffers

An easy to use, automated, retrofitable coolant control system can optimise cutting performance and reduce tooling costs on vertical and horizontal machining centres.
Blow away swarf problems automatically
How much time do operators spend cleaning swarf off components, fixtures and tables on machining centres? Swarf clearance can be automated.
However, with a new range of HPC Jet high pressure coolant systems from Filtration Service Engineering (FSE), users can now get the full benefits of high pressure coolant and hence, reduce cycle times.
Poor coolant delivery and low pressure can lead to a number of adverse effects during metal cutting.
These may include: premature tool failure due to abrasion and thermal shock, chipping caused by re-cutting swarf, dimensional variation due to thermal growth from frictional heat, work hardening of the surface (which can affect secondary operations) and lower levels of surface finish.

Second-hand swarf and coolant systems are on-line
A leading swarf and coolant management system specialist has introduced an online second-hand equipment section as part of its general website.
However, cutting fluids which are pumped to pressures of 70 bar or more and accurately directed at the cutting zone can counter all these problems.
Such systems will also force swarf away from the cutting area especially in deep hole drilling or pocketing routines.
With FSE's new range of HPC Jet high pressure coolant system, engineers can now capitalise on the full the benefits of high pressure coolant on existing CNC machine tools and improve metal cutting efficiency.
Top of the range system in the three model series is the HPC SC 70/100V which offers variable pressure coolant from 10 to 100 bar by way of M function control.
It also has a maintenance-free triple screw pump fitted with a super clean coolant tank rated at 5 micron.
Next is the HPC SC 70FXD system which has a flow rate of 15 to 30 litres/min, a 25 to 70 bar (fixed) pressure, a clean return pump and a super clean holding tank which offers the benefit of increased coolant capacity (around 200 litres) for improved heat dissipation qualities.
The life of the high pressure pump is extended due to the super clean operating environment.
Finally, the 70FXD version has a similar specification in terms of flow and pressure and is supplied with simplex or duplex filter vessels.
Both these fixed pressure coolant units are economically priced.
HPC Jet systems are able to penetrate the high temperature cutting zone on milling, drilling, boring and turning operations to deliver vital lubricant to the cutting edge of the tool.
This means that temperatures are dramatically lowered due to reduced friction, the tools last longer and higher cutting speeds and feed can be adopted.
Drills, for example, can be pushed much harder without pecking cycles and they offer extended life over standard flood coolant systems.
These new high pressure systems can also be linked with SpiderCool - FSE's automated coolant control attachment for machining centres.
