KF series: The big ones are coming.

KF series are the popular, compactly-constructed belt filters. They work as stand-alone filter units or in combination with chip conveyors and they can be used centrally or decentralized. The advantages of the KF series are clear: a cost-effective large filter can take over the supply of several machines (island solution). For applications with cutting oils, due to the higher viscosity and the resulting reduced filter capacity, frequently a large filter is required in order to achieve the necessary filter capacity. This is the ideal area of application for the KF-E with endless belt. Now there are larger models available in the series (KF 1000/1500/2000), which allow still greater filter capacities. Thus cost-effective island solutions can also be realized for multi-machine supply.

KNOLL at GrindTec - still faster and more maintenance-friendly

GrindTec is the world's leading platform for grinding technology – and KNOLL will be there in Augsburg from March 19-22 with MicroPur® and VLO. The focal points are filter systems for the superfine filtration of metal carbide and HSS processing, as well as for gear and profile grinding. New, for example, is an integrated, fully-automatic settling system for the two smallest Micro- Pur® sizes: with simplified installation and removal of filter elements during operation and guaranteed security against leakage. Another innovation is in the KNOLL filter module boxes. They can now be installed directly on the wall. This creates additional free space in the already space-saving filter box system, especially for large systems. Faster and more maintenance-friendly filter change – the newly developed filter element grippers ensure this. And for the first time, you can experience the capacity of the smallest KNOLL MicroPur®120F filter system live in a grinding simulation: this is how dirty oil becomes clean oil.

Two-on-one shredding and pumping unit

The TSC 65 shredder pump saves on chip disposal and cooling lubricant circulation. That is because the pump is a two-in-one shredding and pumping unit. It features a built-in cutting unit which reliably shortens aluminium chips to a pumpable size of about 10 to 20 mm. This eliminates the need for an additional chip reducer. The short chips are pumped together with the cooling lubricant into a central treatment system where they are separated from the cooling lubricant and recycled. The TSC 65 shredder pump has a volumetric capacity of Q = 200 – 1200 litres per minute and can pump up to a height of 28 metres. It is rated for chip loads of up to 10 grammes per litre. A high gas concentration of up to 25 percent is manageable. The TSC is notable for its rugged design and the use of wear-resistant components. For example, the additional cutting head mounting with silicon-carbide low-friction bearings helps prolong the life of the equipment. The TSC's immersion depth is adaptable.

TSS moves heavy loads

Where other systems break down, KNOLL's modular TSS assembly and transport system easily transports loads of 150 to 3000 kg and more per workpiece carrier. Its robust steel construction that ensures great flexural stiffness. Thus the TSS is suitable for clocked belt mounting, small series that vary a lot, the chaining of assembly stations, and also for production in order to automate the transport of workpiece pallets between machine tools. Transport carriages and other devices can be attached and removed and integrated seamlessly into an operation's internal logistics process. KNOLL uses the system itself; with it, KNOLL has been able to more than double the tempo and capacity of assembly and thus also optimize its logistics flows.

The clean one: MicroPur® 

There is only one name in oil micro filters for tool grinding: MicroPur®. With its unique features, it sets the standard:

  • Effective backwashing system with separate pump -> for long filter element life
  • Very short backwashing times of < 4 sec. without air -> for high energy efficiency and short filter downtimes
  • Display of differential pressure on housing and operator panel -> for quick localisation of damaged filter elements
  • To ensure optimal filter quality, the differential pressure for regeneration is adjustable on each individual filter case
  • Filter cartridges are arranged in a tandem configuration -> to minimise space requirements
  • Droplet-free filter changing in < 1 min. -> for minimised maintenance and cleaning

The powerful one: VLO

The new VLO vacuum filter for oil lubricated grinding is a particularly effective solution. It is principally used in the manufacturing of gear cutting machines. Its special design allows up to three filter modules each with a capacity of 300 l/min to be arranged one above the other. Different filtration grades are also possible. For example, machine manufacturers can adapt the filtration capacity of the VLO exactly to the specifications of the machine and the application. Energy wastage and "over-engineering" are a thing of the past.

The flexible one: KF

The new KF compact filter with continuous roll is well suited to use with oil-based cooling lubricants. Thanks to the regenerative filter fabric, customers save on procurement and disposal costs as well as conserving resources. Oil entrainment in particular is considerably reduced. Thanks to the modular design of the compact filter series, the version with continuous roll is also an alternative option for the tried and tested filtration of cooling lubricant using nonwoven filters. Given changing production requirements, it is easy to change over to the system with continuous roll.

Elastomer-free progressing cavity pump

To convey paints and lacquers and, in particular, to provide resistance to aggressive cleaning agents, KNOLL Maschinenbau has developed an elastomer-free version of its proven MX eccentric screw pump. The solvents used would cause elastomers to swell and ultimately render the pump useless. Instead of using elastomers for the stator and the secondary seals, this MX version uses a highly resistant PTFE. The second innovative feature is a torsion bar made of titanium, which balances the eccentric motion of the rotor and makes universal joints unnecessary. Elastomers seals can also be dispensed with here, because the rotor and drive shaft are shrunk-fitted onto the torsion bar. As a result, the MX eccentric screw pump achieves the required degree of chemical resistance while still retaining the typical characteristics of a KNOLL pump.

Flexible combinable.

To KNOLL, conveying means more than just the transportation of chips by using conventional chip conveyors. This is because more and more modern machine-cutting processes are using integrated conveyor systems which employ a combination of extraction and pumping technology. A new addition to our product range is a RIP / RIS conveyor station which can be fully integrated into machining centres and is suitable for both wet and dry machining applications. Up to four feed screws are integrated in the machine bed. They convey all chips produced by metal cutting – with or without coolant – to the coupled disposal station, where they are finally fed into a pump back tank. This is where the RIP and RIS versions are different. The machine's external connection can either be connected to the filtration system (pump back station) or to a central extraction system by a system of pipes.

Energy efficiency with short ROI.

For KNOLL, the future is high-pressure pumps pre-equipped with frequency inverters - such as the new KTS-H high-pressure screw spindle pump which produces pressures of up to 200 bar. This pump offers energy efficiency coupled with high dynamics - because fast tool changing calls for the quick availability of pressure. The KTS-H is capable of ramping up from 0 to 200 bar in 0.5 seconds - as measured from the start signal and including all reaction times. Due to its high pressure rating, it is particularly well suited to deep drilling processes and small tools.

Taking compact to the extreme: Filtering, cooling, supply.

The focal point of a study initiated years ago was the design of compact filtration systems requiring a minimum of floor space. KNOLL's designers have succeeded here in designing the KF compact filter in the style of an advertising column. Now, barely one square metre of floor space is required for installation of the tank, filter and pumps. In addition to being scalable in terms of size and capacity, a key feature of this filtration system is the integrated coolant temperature control system.

Buffers and transports heavy loads.

The TSS transport system is suitable for conveying, buffering, separating and positioning mediumheavy subassemblies and workpieces, such as gearboxes, engines, casings or white goods. The TSS is ideal for cycled flow assembly and for interlinking assembly workstations. In production processes, it makes sense to automate the transportation of workpiece pallets between machining centres. The rugged steel structure offers high flexural rigidity.
Depending on version, the conveyor system can handle loads of up to 1,500 kg/m. Trolleys or other equipment can be transferred in and out unaided. The system can either be set up on the shop floor or mounted on a frame structure. No structural preparations are required for installation. Since the system is modular, it can be planned flexibly and subsequently extended. KNOLL can supply an extensive range of equipment for the TSS, including a 0° - 270° inverter, scissor-lift platforms, and the new workpiece holder wagon for on-site transportation.
