Machine tool cleaning in the metalworking industry and the tooling industry

Regular cleaning of machine tools should be an essential part of any maintenance plan. In practice, however, this means hours of tedious manual work, and standstill of the machines at the same time.

With the unique ph-cleantec process, on the other hand, the cooling lubricant of the machine tool is sucked in and heated, and the machine tools are cleaned effortlessly and in the shortest possible time with their own cooling lubricant. This motivates the colleagues and, above all, saves time and money.

Cleaning machine tools (tooling machines)

OUR SOLUTION: LOW-PRESSURE HOT CLEANING AS IDEAL ALTERNATIVE

The low-pressure hot cleaning process combines a pressure of 3 bar to max. 14 bar with a high working temperature of up to 95°C.

The low pressure ensures that no damage or splash effects occur. The high temperatures, in turn, are ideal for loosening greasy and oily contaminants - i.e. cooling lubricant and cutting oil.

Easy handling is achieved by means of a lance which allows to access even hard-to-reach places effortlessly. The operator does not have to reach into the machine with his hands, so that injuries are excluded. The tools remain in the holder and are cleaned at the same time.

The time saved, that is working time and machine downtime, compared to manual cleaning is enormous. Even a tool magazine with 60 places can be cleaned in a few minutes. For the cleaning of a whole machine, our customers speak of 20 - 30 minutes instead of 3 - 4 hours.

The machine's own cooling lubricant is used as the medium. This means that the emulsion is not diluted and no foreign substances are introduced. The coolant can be filled into the tank of the hot cleaning device or sucked directly from the tank of the machine tool. Cutting oil can be filled into the tank of the hot cleaning device.

We recommend the following devices:

  • Machine tools with cooling lubricant: Devices of the SRE- and the SR-line
  • Machine tools with cutting oil: Device 1000 OSE

ECONOMIC EFFICIENCY

  • Experience shows that cleaning takes 20 - 30 minutes instead of 3 - 4 hours. This means that you can work through until 3 p.m. instead of 12 a.m. on the cleaning day. This saves valuable working time and you can produce for longer.
  • With €25 full costs for one hour of work and €150-€250 less loss of earnings for one hour of downtime, you come to savings of over €500 per month (per machine, assuming monthly cleaning cycle).
  • With 10 machine tools, the investment in a hot cleaning device pays for itself in 1-2 months.
  • Also: Tendency of decreasing costs for maintenance and servicing, as faults such as leaks in clean machines can be found and repaired much more easily and quickly.
  • Risk of injuries, for example when cleaning the drive trains or the tool magazine, is minimised - this increases work safety and saves downtime and trouble.

OPTIONS

In combination with an on-top parts cleaning level (collector), the ph-cleantec devices can also be used as mobile wash tables for parts cleaning.

Furthermore, it is possible to thermally sterilise (pasteurise) the cooling lubricant in bypass-mode. This reduces or even totally avoids the addition of biocides, i.e. fungicides and bactericides.

SEE ALSO

The low-pressure hot cleaning process is perfectly suited for cleaning tool magazines and tools.

In applications in the field of precision and ultra-precision mechanics, heat exchangers and electric motors must be used to ensure that the bath temperature of the cooling lubricant is as constant as possible in order to ensure trouble-free operation even in summer or at high outside temperatures. Here, too, the low-pressure hot cleaning units offer an ideal solution.

REQUIREMENTS

When cleaning a machine tool, the tool magazine poses a special challenge: It is particularly dirty, very difficult to access and it is easy to injure oneself on the sharp tools.

The tool magazine in particular should be cleaned properly and regularly, because adhesions due to coolant, oil or chips cause damage to the tool holders and the handling systems.

The tool magazine is usually cleaned manually with the help of rags and, if necessary, brake cleaner, with which heavy contamination may be sprayed.

This takes a lot of time and involves the risk of foreign substances being intro­duced into the coolant. In addition, there is a non-negligible risk of injury while cleaning.

Cleaning extrusion machines

General information

Extrusion means the processing of plastics.

After the liquid plastic has been obtained, it is pressed via a nozzle into a so-called calibration (tool), which has the shape of the future profile. During these thermal processes, waxes are released or added as lubricants. These waxes harden in the system and must therefore be cleaned.

Nowadays, a wide variety of profiles are produced by means of extrusion. Mostly, the material is cooled in a water bath after forming.

Advantages of low-pressure hot cleaning technology

  • Optimum accessibility in complex tools, e.g. the various cooling channels can be cleaned very well with our tools.
  • Our devices can also be used directly in the plant, as usually the profile is cooled down in a water bath
  • No aggressive cleaners
  • Compared to ultrasonic bath an efficient and fast process
  • Corrosion protection can be added if necessary
  • Mobile system
