KNOLL Systems for Chip Processing

The treatment of chips has many advantages: they are dry and separated by type, so disposal costs are low. Depending on the material, it may even be possible to sell the chips. A system for chip treatment includes different components depending on the requirements: conveyor and collection devices, magnetic separator technology, filter and volume-reducing briquetting presses. Containers or chip silos are also required. The components can be linked to one another and operated completely automatically.

  • Central Chip Processing with by a lift-tip device, chip breaker, conveyor to chip centrifuge, discharge via scraper belt conveyor to containers via a swivel chute. Fluid Centrifuge for cleaning of the separated oil.

Areas of application

The chip processing system is suitable for both semi-automatic and fully automatic processing of metal chips. Chips are transported from the processing machines by automatic conveyor systems or by operating personnel with trolleys/containers. The system is used in virtually all production areas of the machining industry. Different materials (e.g. aluminium, steel or cast iron) can be processed by means of separate systems.

Properties

  • Chip drying is essential to ensuring safe transportation on public routes
  • Volume reduction reduces storage and transportation costs
  • Recovery of chips and cooling lubricant protects the environment and reduces costs

Possible main components

  • Lifting/tilting device
  • Chip reducer
  • Chip centrifuge
  • Chip conveyor
  • Separating channels
  • Magnetic separator technology
  • Briquetting press
  • Cooling-lubricant filter and collecting container
  • Control technology and cabling

  • Chip silo

 

 

KNOLL: LubiCool®-S High Pressure Coolant System

 

 

KNOLL’s LubiCool®-S high-pressure unit is designed for mobile use with machine tools in machining processes, particularly automatic lathes with a fixed/sliding headstock. The unit is used to clean the cooling lubricant and to supply the machine with high pressure coolant.

The potential application areas include

  • Challenging machining processes
  • Machining operations involving difficult materials (e.g. high-alloy steels, titanium, copper, bronze
  • Situations where space for installation is particularly limited
  • Initial equipment and retrofitting

KNOLL: VL Vacuum Filter Systems

Application Areas

The vacuum filter VL is a high performance filter for cleaning the coolant lubricants of machining processes, in particular grinding processes. Depending on the requirement, several filter elements can be used for individual machines (locally) or machine groups (centrally). Its special efficiency is a result of high energy efficiency, low cooling lubricant loss and low disposal costs.

  • Production of pure concentrate with low residual moisture as standard without filter aids
  • Optimized filter capacity, filter quality and energy efficiency thanks to a flawless control system
  • Continuous filter process without reverse flushing interuption
  • Forced degasification of coolant lubricants in the filter
  • Can be used for different machining processes, materials and coolant lubricants
  • Problem-free removal of light metal chips

Filtering Process

The contaminated liquid flows through the inlet box into the filter. It then runs through the filter belt into the filter chamber. From there, a filter pump conveys the filtered medium into the clean tank. The vacuum pump generates a vacuum in the filter chamber. The high pressure differential at the filtering surface creates a thick filter cake (concentrate) on the filter belt. This filter cake also acts as a filter medium and separates smallest dirt particles. The filter and vacuum pumps are regulated demand-driven and and provide for a tranquilized, constant filtering process.

Filter Belt Regeneration

The permeability of the filtering surface decreases as the filter cake grows. Now the belt drive switches on and conveys the carrier belt together with the filter belt a little further. Thereby, permeable filter belt reaches the filter surface and the volumetric flow through the filter surface continues to rise again. The feed length varies in such a way that the set clock cycle remains constant.

The endless filter belt passes through the following stations:

  1. Filtering section (separation of the dirt particles)
  2. Drying section (extraction of liquid from the concentrate)
  3. Cleaning with air or brush (removal of the concentrate)
  4. Back flushing (removal of the residual particles)

KNOLL: Chip Reducers

 

  • Chip Reducer ZV-J (Single Shaft with Double Faced Blades)

KNOLL chip reducers cut metal and plastic chips to bulk material quality. The reducers can be installed on machine tools or at central collecting points. Depending on model, horizontal or vertical chip feed is possible, together with faulty part ejection in some applications.

Please contact us for more information on the KNOLL Chip Reducers for your machining process.

 

COVID-19 Message from KNOLL

Dear Sir or Madam, dear business partners,

We wish to inform you that we have introduced special measures in the company as a result of the coronavirus crisis. Approximately 50 % of the entire workforce are no longer in the company. They are either working from home, on reduced working hours or are on annual leave. Apart from a small number of exceptions, the apprentices and trainees are also at home. The reduced workforce on-site reduces the contacts and risk of infection.

Our plant remains fully functional despite the restrictions. At present the material supply is secured. Our service and sales team is also available to assist you if needed. All our employees can still be reached via the normal channels either by telephone or e-mail. We are also working with Microsoft Teams and can communicate with you by video conference.

With best regards and stay safe!
