CRANKSHAFT/CAMSHAFT MILLING N20 CM | N30 CM

The NILES-SIMMONS Cranks­haft Mil­ling Cen­tres N20 CM and N30 CM are based on the modu­lar buil­ding-block sys­tem of the N‑series. Two sym­me­tri­cally arran­ged tool spind­les with elec­tro­ni­cally syn­chro­ni­zed tor­que dri­ves and two com­pact and powerful mil­ling units ensure rough and finish mil­ling ope­ra­ti­ons on cranks­haft main and pin bea­ring jour­nals by means of these mil­ling cen­ters. Elec­tro­nic gear­box and high pre­cis­ion inter­po­la­tion of spindle sys­tems as well as spe­cial com­pen­sa­tion stra­te­gies enable pro­cess capa­ble manu­fac­ture of high pre­cis­ion bea­ring geometries.

In addi­tion to cranks­hafts for trucks and pas­sen­ger vehic­les, cams­hafts and eccen­tric shafts up to 2400mm can also be machi­ned on the CM series.

Added value:

• Pro­cess capa­ble dry mil­ling of bea­ring geo­me­tries, chee­king and top­ping of coun­ter­weights in addition
  to other con­cen­tric and eccen­tric fea­tures with one or  two exter­nal cylind­ri­cal cutters
• Cus­to­mi­zed clam­ping solu­ti­ons with inte­gral or sepa­rate radial ori­en­ta­tion of work pieces

• Up to two NC-posi­tio­ned steadyrests
• Semi-auto­ma­tic tool clam­ping, auto­ma­tic trans­fer of pre-set tool data via ID-chip
