Finishing boring tool ZMAC

fineinsertsemi-finishing

The NIKKEN ZMAC Advanced modular boring range provides fantastic and precise performance for any semi-finishing and fine finishing process. Available with exclusive NIKKEN selected insert choices and grades we have two distinct solutions to meet any requirement: NIKKEN MP/MS - Triangular insert geometry and pocket for fine finishing. NIKKEN CC - Rhomboidal insert geometry and pocket for semi-finishing. Also available, should a third party insert choice be preferred, is our NIKKEN ZMAC Advanced ISO option with cartridge pockets to suit more standard inserts choices as required. ZMAC is our ultimate fine boring solution - The boring cartridge itself, unlike competitor solutions, features a highly rigid double-contact support which is designed to fully support the insert seat throughout the entire range of its range of travel. The locking bolt is applied precisely at 90 degrees to the adjustment screw to negate any possiblity of deflection and preset measurment variation. ZMAC is constructed using a precise graduated micron dial ring which features an internally ground thread and is special heat treated to HV800. This is mated to a precision ground cartridge thread which is also hardened and heat treated to HRC50-55. The solution is supplied with centre through coolant supply as standard which feeds the coolant through the arbor, any spacers and through the ZMAC head directly above the cutting insert for optimum cooling even in a confined bore. To reduce the weight of the assembly and operate at higher rotation speeds we can also provide our ZMAC Alpha option.
