CRANKSHAFT TURN-BROACHING N20 TB | N30 TB

The NILES-SIMMONS Cranks­haft Turn-Broa­ching Machi­nes N20 TB and N30 TB are based on the modu­lar buil­ding-block sys­tem of the N‑series. Two sym­metri­cally arran­ged tool spind­les with power­ful and elec­tro­ni­cally syn­chro­ni­zed spindle dri­ves and two mir­ror imaged broa­ching units with highly dyna­mic rotary axes to locate the tool discs ensure effi­ci­ent tur­ning and turn-broa­ching ope­ra­ti­ons on cranks­haft bea­rings and other con­centric fea­tures of cranks­hafts. The use of maxi­mum 2x48 tool pockets to locate the rever­si­ble cut­ting inserts ensu­res high fle­xi­bi­lity and long tool life due to the use of sis­ter tools.

Added value:

• 2 sym­metri­cal, tem­pe­ra­ture con­trol­led motor spindle dri­ves with excel­lent power and tor­que parameters
• Rapid posi­tio­ning of cut­ting tools by means of highly dyna­mic rotary axes
• Simul­ta­ne­ous ope­ra­tion of both tool disks with inde­pen­dent feed rates

• Adap­ta­ble clam­ping solu­ti­ons with shaft chucks to machine flange and post in one setup
• Semi-auto­ma­tic tool clam­ping, auto­ma­tic trans­fer of pre-set tool data via ID-chip
