Mitarbeiter montiert System mit Pumptechnik - KNOLL Maschinenbau GmbH

A conveyor and filter system with pump technology is suitable for fully-automatic chip transport from several processing machines to a central filter system. Cooling lubricant serves as the carrier medium. This system is especially advantageous in production areas with a large machine park. It is constructed to save space and be flexible with regard to its overall height. The user has many possibilities for expanding and converting his machine park. Little maintenance and service is required.

Areas of application

The circuit system is suitable for the fully automatic return of the chip/cooling-lubricant mixture of several processing machines to a central separator/filter. This central separator/filter supplies the machines with cleaned cooling lubricant. The system is used in large production areas with a machine train of 30 and more machines and as an island solution (wet processing). 

 

Properties

 

Main components

Central filter systems

Central filter systems are in a position to clean cooling lubricant from entire production areas and islands outside of the production environment. The selection of filter technology depends on the number of machines, the processing type, the chip materials, and the desired cooling lubricant quality. KNOLL offers the right technology for every application. Select from reversible flow and belt filters, as well as hydrocyclone and superfine filter technologies.

Sedimentation technique

The scraper belt conveyor SR collects the mixture of chips and cooling lubricant of the machine tools. The chips sink to the bottom of the container and are discharged through the integrated scraper belt. The plant is suitable as a pre-separator of short chips and grinding sludge.

Kratzbandförderer SR - KNOLL Maschinenbau GmbH

For cutting off sedimenting short chips and sludge with a high coolant flow.

Reversible flow filter technology

Reversible flow filters are constructed so they are space-saving and can be used universally. They are suitable for full-stream cleaning, they are pressure stable and energy-efficient. Especially advantageous: no filter aids are required. Therefore, ongoing costs are lower. If necessary, a chip pre-separator can be integrated.

Belt filter technology

Belt filters are in a position to separate cooling lubricant and chips from various working processes. For this, they use a filter belt and gravity or an additional vacuum system. The result: the cooling lubricant exhibits a high degree of purity and cooling lubricant loss is low. The chips contain only a little residual humidity. Therefore, the disposal costs are low.

Hydrocyclone technology

A hydrocyclone can be used very flexibly. It separates all sediment-capable solids from low-viscosity fluids such as water and emulsions. No filter consumables are required. Therefore, operating costs are low. 

Hydrozyklon F60 - KNOLL Maschinenbau GmbH

Simple, modular centrifugal separator for separating sedimenting solids from low-viscosity liquids (e.g. emulsions) without filter consumables. Filter performance up to 90 l/min per module.

Superfine filter technology

The KNOLL MicroPur® superfine filter is predestined for tool grinding and honing and lapping processing. For the greatest component precision and surface qualities, even the least contamination must be removed from the oil. The KNOLL MicroPur® uses cost-effective, backflushable filter cartridges. With these, it achieves a degree of purity <5 µm. It is suitable for the processing of carbide metal, HSS, and other materials. 

Feinstfilter MicroPur®  - KNOLL Maschinenbau GmbH

Backflush filter for separating superfine impurities from oils and aqueous solutions. The ideal area of application is the tool grinding of hard metal and HSS. High filtration grade (1-3 µm). Filtration capacity up to 480 l/min.

Reverse flow systems

Reverse flow systems for pump technology transport the chips together with the cooling lubricant through pipes back to the central filter system. Depending on requirements, the conveyor systems are integrated into the machine or provided underneath the chip conveyor.
