Minimum quantity lubrication systems

Minimum quantity lubrication system AerosolMaster 4000 ATS

Application

The KNOLL AerosolMasterTM 4000 ATS is a minimum quantity lubrication system for almost all production processes with geometrically determined cutting edges, e.g. on processing centers, transfer lines, turning, milling, drilling, and sawing machines. Thanks to the broad product line and unique ATS (aerosol dry lubrication) technology, the system is suitable for

easy processing with external or internal aerosol feed,
complex processes, where at least one of the following criteria applies: mass production, deep-hole drilling, thread forming, high speeds, many tools, small tools, monolith tools, multispindle machines, transfer lines, automotive, aerospace, medical, tool/mold design and construction.

Properties	Benefits
Oil content and air pressure appropriately adjustable with 30 programs	• Defined aerosol quality and constant aerosol flow, even with changing tools • No pressure fluctuations on the tool • Great process reliability • Long tool service life, short processing times • Low air and oil consumption • Easy handling
Very fine and homogeneous aerosol	• Low-loss lubrication • High speeds up to 45,000 rpm possible
Nearly dry chipping	• No adhesions • Less cleaning work for parts and machines
Immediate availability of the aerosol on the blade after spindle start	• No maintenance times • Great process reliability
Long aerosol lines up to 50 m possible	Flexible set-up
Optional machine connection via ProfiBus or ProfiNet	• Quick and variable NC programming • Little adaptation required • User-friendly
PLC control optionally by machine manufacturer with KNOLL program module	Ideal for OEM customers

Description

Compressed air flows into the injector via an air venturi nozzle
Oil is fed to the venturi nozzle from the container
The venturi nozzle mixes air and oil into a very fine aerosol
Air and aerosol control valves define the air pressure and degree of saturation of the aerosol
The oil/air mixture then flows through:→ Rotary feed-through → Spindle → Tool holder → Tool → Exit opening(s) at the processing point(s)

Minimum quantity lubrication system AerosolMaster 4000 Cryolub

Application

The KNOLL AerosolMasterTM 4000 Cryolub is a minimum quantity lubrication system based on cryogenic cooling technology for manufacturing processes that use geometrically defined cutting edges, e.g. on machining centers, transfer lines, turning, milling, drilling and sawing machines.

Thanks to unique ATS technology in combination with Cryolub cryogenic cooling technology, the system is ideal for demanding machining of titanium- and nickel-based alloys (e.g. implants), Inconel, composite materials (e.g. carbon) in the medical device, aircraft and energy industries.

Properties	Benefits
Oil content and air pressure adjustable as required via 30 programs	• Defined aerosol quality and constant aerosol flow, even when tools change • No pressure fluctuations at the tool • Great process reliability • Long tool lives, short machining times • Low air and oil consumption • Easy handling
Very fine and homogeneous aerosol	Low-loss lubrication
Almost dry machining	• No sticking • Minimal cleaning of parts and machine required
Immediate availability of aerosol and CO2 at the cutting edge as soon as spindle starts	• No wait times • Great process reliability
Long aerosol lines up to 50 m possible	Flexible setup
Optional machine connection via ProfiBus or ProfiNet	• Quick and variable NC programming • Little adaptation effort • Very user-friendly
CO2 content adjustable as required	• Low consumption • Optimum tool temperature • Workpiece temperature = room temperature

Description

MQL

Compressed air flows into the venturi nozzle through a compressed-air control valve
The venturi nozzle draws in oil from the container and mixes it with the air to form a fine aerosol
Air pressure and aerosol pressure control valves define the air pressure and saturation level of the aerosol
The oil/air mixture flows through, in succession, the: → rotary union → spindle → tool holder → tool → discharge opening(s) at the machining point(s)

Description Cryolub

CO₂ supply by the customer
CO₂ switchover valve: switchover valve: Disconnects the CO₂ in case of danger
CO₂ control valve: Controls the cooling capacity via the CO₂ flow rate
CO₂ distributor (optional): Allows additional, external cooling nozzles
CO₂ switchover valve: Provides fastest response times
Aerosol and/or CO₂ discharged at the tool or the external nozzle. Scheme
