Comparison<\/p>\n\t\t\t\t\t

When a precoat filter is the better choice<\/h2>\n\t\t\n<\/div>\n\t\t\t

Belt filter systems<\/a> remove coarse and fine chips as well as other particles, but generally do not achieve filtration in the lower micron range. Magnetic filters are suitable only for ferromagnetic particles. Precoat filters also capture fine, non-magnetic particles and achieve filtration fineness down to 5 \u00b5m. They are therefore particularly suitable when high surface quality, long tool life and consistent coolant cleanliness are required.<\/p>\n\t\t\t\t\t\n\t\tRequest a consulation\n\t<\/a>\t\t\n<\/div>\n\n<\/div>\n

Longer tool life<\/h2>\n\t\t\t\t\t

Clean coolant can extend tool life by up to 50%. Fewer tool changes mean lower costs and more machine uptime.<\/p>\n\t\t\n<\/div>\n

Consistent machining quality<\/h2>\n\t\t\t\t\t

Clean coolant reduces dimensional deviations and surface defects. This helps components meet dimensional and quality requirements even in high-volume production.<\/p>\n\t\t\n<\/div>\n

Reduced coolant consumption<\/h2>\n\t\t\t\t\t

Our precoat filters return cleaned coolant to the process at a high level of purity, extending its service life. This significantly reduces the need for fresh fluid. The compressed-air-assisted backflushing process uses only coolant already present in the filter dome, so no additional water is required. This reduces operating costs and waste volumes.<\/p>\n\t\t\n<\/div>\n

Background<\/p>\n\t\t\t\t\t

How precoat filters can reduce operating costs<\/h2>\n\t\t\n<\/div>\n\t\t\t

A precoat filter uses a support medium on which filter aids such as diatomaceous earth, cellulose, perlite or silica gel form a stable filtration layer. This precoat layer retains particles down to 5 \u00b5m and helps maintain consistent coolant cleanliness. Once the layer is saturated, the filter is automatically regenerated and a new precoat layer is applied. This can extend tool life and reduce the need for fresh fluid..

Without adequate coolant filtration, the following problems can arise during production<\/strong>:<\/p>\n\t\t\t\t\t

Tool wear<\/h3>\n\t\t\t\t\t

Fine particles can damage cutting tools and shorten their service life.<\/p>\n\t\t\t\t\t

Loss of machine performance<\/h3>\n\t\t\t\t\t

Deposits in pipes and pumps can reduce the flow rate and impair system performance.<\/p>\n\t\t\t\t\t

Quality issues with components<\/h3>\n\t\t\t\t\t

Contaminated coolant can cause dimensional deviations and surface defects.<\/p>\n\t\t\t\t\t

High coolant consumption<\/h3>\n\t\t\t\t\t

More frequent coolant replacement increases the demand for fresh fluid.<\/p>\n\t\t\t\t\t

Rising operating costs<\/h3>\n\t\t\t\t\t

Frequent tool changes, higher disposal costs, and unplanned downtime can increase production costs.<\/p>\n\t\t\n<\/div>\n\n<\/div>\n

Cost-effectiveness<\/p>\n\t\t\t\t\t

How precoat filters can reduce operating costs<\/h2>\n\t\t\n<\/div>\n\t\t\t

A precoat filter can reduce operating costs in several ways. Clean coolant can extend tool life by up to 50% and reduce the number of tool changes required. At the same time, filtration extends coolant service life and reduces the need for fresh fluid. The actual cost savings depend on the application, particle load and operating conditions.<\/p>\n\t\t\t\t\t\n\t\tRequest a consulation\n\t<\/a>\t\t\n<\/div>\n\n<\/div>\n
