Filtration In The Process of Machining

Machining is the process of changing the external dimensions or properties of workpieces by processing machinery. It is divided into cold and hot machining according to the temperature status of the workpiece being machined. In the process of machining, many fluids used for cooling and lubrication are recycled to reduce input costs and waste of resources. Filtration removes impurities from waste fluids and brings them up to reuse standards. Hanke is equipped with a professional technical team to provide you with customized machining filtration solutions, including machine tool coolant circulation & filtration solutions, cleaning fluid filtration solutions, hydraulic and lubricating oil filtration solutions.

Machine Tool Coolant Circulation & Filtration

Background
Aqueous-based liquid coolants are used to cool and lubricate metal machine tools to facilitate metal cutting, extend the equipment service life and maintain part dimensions.
Problem
Machine tool coolants get contaminated with metal shavings, workshop dust and oil from metal surfaces. Contaminated coolants cause premature equipment failure, nozzle damage, shortened coolant life, and having a negative impact on surface finish.
Solution
Coolants are typically recycled to reduce costs and contaminated coolants need to be filtered before reuse. Bag filters and cartridge filters are employed for machine tool coolant filtration. Bag filters are recommended when the system has a high flow or requires a large liquid volume while cartridge filters are recommended when the system has a low flow or requires a small liquid volume.

The equipment is equipped with 2 bag filters for machining filtration.

Cleaning Fluid Filtration

Background
Manufacturing industry generally requires cleaning processes to remove grease and dirt from part surfaces. As a result, a large quantity of solvents and cleaning agents are required and it will inevitably increase the water displacement, thus greatly increasing the environmental load. Cleaning fluids are generally recycled to reduce the environmental load and input cost.
Problem
These used cleaning fluids contain impurities such as grease and dust and may clog the equipment, causing equipment wear and increased maintenance costs.
Solution
Therefore, cleaning fluids need to be filtered before reuse. Typically, bag filters are adopted for cleaning fluid filtration as they can not only effectively remove impurities in cleaning fluids, but also require a low price to minimize the input cost.

Hydraulic & Lubricating System Filtration

Background
Hydraulic and lubricating oil filtration is a key element in engines, compressors and other equipment for efficient operation and maintenance.
Problem
Contaminated hydraulic and lubricating oils cause equipment wear, leading to engine and hydraulic equipment failures, increased maintenance frequencies and higher maintenance costs.
Solution
Mobile trolleys with bag filters are recommended for hydraulic & lubricating oil filtration as they can move freely featuring high mobility and easy to operate. Therefore, this kind of devices can effectively remove impurities from hydraulic & lubricating oil, protect the downstream equipment and extend the service life of downstream equipment.
