INDUSTRIAL CLEANING FEATURE DON’T CUT CORNERS WHEN IT COMES TO CLEANING
Machine shops using water-based metalworking fluids are urged to initiate a regular system cleaning regime amid fears that many operators are short-changing their cleaning processes in order to reduce machine downtime. Water-based coolants are susceptible to bacterial growth that can severely impact fluid stability and its operational performance. “Operators often do not understand the necessity of system cleaning while their production directors are happy for them to shorten cleaning time in order to reduce overall machine downtime,” comments technical director Martyn Mann. “Insufficient cleaning is storing up problems for a later date because dirty fluid will inevitably have debris and other contaminants including bacteria which feed upon the fluid, reducing its operational effectiveness and ultimately impacting machine performance, tool life and finished workpiece quality.” Millers Oils recommends regular
monitoring and testing of metalworking fluid for both bacteria and pH value to ensure the fluid remains in top condition allied to a regular cleaning regime. “Weekly checks such as dipslides or refractometers will ensure that bacteria is kept under control and pH levels are at their optimum,” continues Mann.
CLEANING UP WITH PLASMA TREATMENT
Henniker has launched the CIRRUS and NIMBUS atmospheric plasma treatment systems which solve manufacturing issues associated with poor adhesion. Available as both single and dual
“Low pH levels for example, could be
due to microbial contamination and ultimately lead to reduced corrosion protection. A regular cleaning regime will eliminate many of the machining problems that operators face on a daily basis. Coolant systems need to be regularly cleaned in order to function properly (sump, pipework, machine and guards) before refilling with fresh metalworking fluid. Be careful to ensure that you are using a cleaner compatible with the fluid and don’t ever put clean fluid in a dirty machine or sump.”

nozzle versions they are suitable for surface activation and cleaning of a wide range of materials including polymers, metals, glass and ceramics. Both models are extremely simple to operate via the front panel soft-keypad and can be interfaced with external control equipment using the rear panel Sub-D connector providing a variety of I/O control inputs and status read-back to ensure seamless operation with production lines or robot cells. CIRRUS and NIMBUS operate from a standard single-phase electrical outlet and require only compressed air for operation. The compact controller features an interlocked airflow regulation unit as standard so that no ancillary equipment is required. The systems address specific material treatments including plasma cleaning; plasma surface activation to improve adhesion; PEEK and other engineering polymers; PCBs; metals; ceramics; and glass.
