The Environmental Benefits of Magnetic Filters within the Metalworking Industry
Environmental issues within the manufacturing industry have quickly become a significant consideration for most companies, forcing many to take a more proactive role in developing cleaner manufacturing processes. This is particularly relevant for the metalworking industry wher the waste generated by CNC machines and other precision processes can be considerable and difficult to dispose of.
With the UK Government ambitiously aiming to slash emissions by 78% by 2035, the green issue is here to stay and leading business owners to investigate more efficient means to meet the demand of lowering the environmental impact of their work. Existing legislation such as the Hazardous Waste Regulation 2005 and the Environmental Protection Act 1990 also determine strict procedures.
Demonstrating compliance to environmental standards is vastly becoming the norm among many businesses, with manufacturing organisations in particular putting systems into place that will not only benefit the environment but also reduce costs and improve efficiency.
ISO 14001 is the internationally recognised standard that determines the framework for effective environmental management. It was first published as a standard in 1996, specifying the requirements for an Environmental Management System (EMS), applying environmental aspects that an organisation has control over, and where it can be expected to have an influence. Plus, with its nature of being a generic standard, it can be applied to any organisation irrespective of size and sector.
As well as making positive steps to protecting the environment, ISO 14001 also comes with many financial benefits including cost savings in waste, recycling and consumption, whilst also having a positive effect on corporate or brand image in terms of demonstrating Corporate Social Responsibility. Increasingly it is also becoming a pre-requisite for companies when submitting tenders for larger projects.
Metalworking Fluid Efficiency
Minimising waste is one of the more significant issues for the metalworking sector with cutting fluid or CNC coolants and contaminated consumable filter disposal often proving to be one of the most environmentally problematic factors for mechanical processes such as milling, grinding, honing, drilling and tool cutting.
Although these fluids play a vital role in many machining processes - such as impacting productivity, cutting tool life and quality of the workpiece - they can also contain compounds with high ecotoxicity and low biodegradability. Disposing of used oil or coolant or saturated consumable filters is an expensive process and has an adverse effect on the environment. It usually a requirement that this is done by a licensed contractor, but often ends up in landfill sites or heading for incineration.
During the manufacturing process, used metalworking or cutting fluids become contaminated with oils, fines, metals, and bacteria. If oils and coolants become contaminated this can cause tool breakages, failure to meet surface finish tolerances and abrasive damage to machine parts such as pumps and valves. It can also put operatives at risk from swarf content or bacterial build-up, see our guide to Safe Handling of Metalworking fluids.
One of the most effective improvements that a manufacturer can make, not just for environmental benefits, but also to improve its health and safety processes, is to extend its cutting and cooling fluid lifespan by cleaning and reusing fluid. By doing so, businesses also enjoy substantial economic benefits with cost savings driven by factors including reduced machine downtime and lengthened tool life.
One effective step that metalworking companies can take to implement a fluid life extension process into the machining is by simply installing a magnetic filter.
Magnetic filtration is a positive contribution to companies’ environmental policies - helping many businesses maintain their ISO 14001 certification - as well as making a major contribution to promoting the safe, environmentally friendly, handling of metalworking fluids. Cleaner fluids also reduce the risk of human contact with metal fines, thereby reducing the risk of cuts, abrasions, and dermatitis.
Traditional filters, such as paper, bag or band filters, can be ineffective at protecting industrial fluids against fine metal particles smaller than 5-10 microns. They also create additional problems with the disposal of the saturated filter. Saturated filters need to be disposed of in a safe and controlled manner, potentially leading to the involvement of a third party, causing additional expenses.
A magnetic filter will effectively remove almost all ferrous contamination from fluid, without the need to regularly replace consumable or disposable media filters, and without having any adverse effects on the fluid's key additives. By reducing the need for consumables, magnetic filtration systems can reduce the environmental impact of metalworking fluid cleaning, The cleaning process is quick and easy, allowing ferrous waste to be safely collected and recycled.
