Ultra-Fine Filtration System for Tool Grinding
Vomat’s KFA 1500 Compact Filter System provides tool manufacturers and regrinders with a high-performance, low-maintenance, ultra-fine filtration system for grinding high-speed steels (HSS) and carbide materials.
With the KFA 1500 Compact Filter System, machine manufacturer Vomat provides tool manufacturers and regrinders with a high-performance, low-maintenance, ultra-fine filtration system for grinding high-speed steels (HSS) and carbide materials. According to Vomat, the system is capable of optimum quality with high purity of NAS 7/8 or 3-5 µm for very large batches.
According to Vomat, demanding grinding applications require a high-performance filter system that positively supports and influences the process flow. Ultra-fine filtration enables grinding oils to remain in the system significantly longer, and when cleanly filtered, they help increase the dimensional accuracy and surface quality of the products. Additionally, the right filter system also reduces energy consumption and disposal costs.
The KFA 1500, which measures 260" × 100" × 103", reportedly has a tank volume of 10,000 liters and a filter capacity of 1,500 liters per minute. The medium is filtered by high-efficiency precoat filters in full flow at a filter fineness of 3-5 μm. Filtration is said to take place on demand and in an energy-efficient manner via a frequency-controlled system pump. The special drying unit is designed for large batch sizes.
The cooling performance in the cold water circuit of the KFA 1500 is 200 kW in continuous operation. Vomat says the temperature accuracy in the tolerance range of up to ±0.2 °C contributes to the optimum quality of the product.
Due to the precoat principle, there is reportedly no contamination of the swarf by filter aids. The residual moisture of the swarf is between five and ten percent, and the recyclable material is processed directly into a suitable transport container for recycling companies. The control technology can also be monitored and operated remotely.
As an option, Vomat also offers a compression cooler with external condenser and high control accuracy, as well as a material-dependent pre-separation system.
