Application // Laser Reflector Machining, D120, 80.000 rpm

[stm_post_info]

SUBJECT

For an accurate deflection of laser beams freeform mirros with a surface finish of better 10 nm Ra are required. Presented machining example shows the freeform creation of such a reflector based on a polynomial function. A Levicron tool spindle type ASD080H25 on an ultra-precision machining center with slow-tool servo function and a diamond ball end mill R2 were used.

Rough cutting was done with a standard carbide tool at 80.000 rpm, 1 mm cutting depth and 0.4 mm feet rate per cutting edge. Rough cutting time: 45 min. Finish cutting was done at 5 micron cutting depth and 5 micron feedrate per cutting edge at 80.000 rpm. Finish cutting time: 24 h.

Achieved surface finish: 7 nm Ra
