Aktiebolaget SERVUS marknadsför Höghastighetsprecisionsfräsmaskiner från KERN Microtechnik GmbH.

KERN Microtechnik GmbH har sedan 1983 specialiserat sig på att konstruerat och tillverka vertikala CNC-bearbetningsmaskiner med höghastighets frässpindlar för mikrobearbetning med exceptionella ytkvalitetskrav.

Höghastighets precisions­fräsmaskiner från KERN

Eftersom KERN inte kunde hitta maskiner på marknaden som var tillräckligt noggranna för sina applikationer byggde de sin allra första KERN maskin redan 1983. Sedan dess har de konstruerat och tillverkat vertikala CNC-bearbetningsmaskiner för mikro- bearbetning, liksom för hårdbearbetning med exceptionella ytkvalitetskrav, med höghastighets frässpindlar.

Legobearbetning med mikroprecision
Efter mer än 45 års erfarenhet inom kontraktstillverkning av mikrokomponenter, verktygsinsatser, komplexa volym komponenter och prototyper gör KERN experter på området. De kombinerar mikrofräsning, höghastighetsfräsning, hårdbearbetning och konventionell CNC fräsning, tråd- och sänkgnistning liksom plan- och jiggslipning.

KERN Evo

beskrivning
teknisk info

KERN Evo Evolution. Specifika maskinegenskaper: De digitala direktmatningsdrivningar som är monterade på KERN Evo ultraprecisions bearbetningscentrum ger snabb acceleration och höga matningshastigheter. Dessa krafter absorberas av det tunga monoblock maskinstativet i polymerbetong.

The result of intelligent evolution!

Every KERN Evo contains many years of consistent development to ensure ultra-high precision in CNC milling at high and medium volumes.

With its proprietary X-Y cross table, KERN Evo delivers maximum precision in a small installation space. The design allows maximum smoothness and excellent surface finish (Ra < 1 μm) even at high speeds and acceleration values.

Short distances between components and drives ensure minimal angle errors, while ultra-high resolution direct measuring systems guarantee maximum repeat accuracy in a working space of 300 x 300mm. KERN Evo can be optionally equipped with a 4th and 5th axis without compromising the stability and high precision of the basic machine.

With high quality components in all peripheral modules and easy automation, KERN Evo is widely used for unmanned 3-shift production in all industries that demand maximum precision on the workpiece.
