APW-R20
automatic scribe marking tool
Structure and function of the marking tool APW-R20
The APW-R20 is a high-quality marking tool for CNC machines, with which surfaces up to 60 HRC with an unevenness of up to 5 mm can be marked.
This tool does not require spindle rotation,
no coolant and no compressed air. With the spindle stopped you can mark as fast as your machine can follow the contour of the characters. Spindle speeds of up to 300 rpm and wetting the surface with coolant or oil are permitted but not necessary.
01
Possible uses
The APW-R20 can be used in any CNC machine with automatic tool change and software for engraving as well as on suitable robots.
It is used to mark a wide variety of materials, from plastics to aluminum and titanium to highly tempered steels of 60 HRC.
With this tool, machined and raw surfaces, even on cast parts, can be evenly marked with an unevenness of up to 5 mm.
Different special needles are available depending on the area of application and the desired font width.
02
Setting the marking depth
Setting the marking depth:
The marking depth is set for the given surface hardness by turning the adjusting ring to a scale value from 1 to 20. The higher the scale value, the greater the scribing force and the deeper the mark.
It is best to start at a scale setting of 6 and then increase or decrease it to suit your needs.
The length of the APW-R20 does not change due to different scale settings.
Scale settings above 15 are only permitted with a small needle spring travel of up to 1.5 mm and should be used in special cases only.
03
Life of the needle
Experience shows that under normal conditions and material hardness the service life of the needle is
several years, or over a marking range of
more than 40 km. Please note that only the special needle manufactured by us
delivers the required marking quality.
