Floor-Type Horizontal Boring & Milling Machines

Cutmax 2FT, in two versions, P and K, the first in a series of four floor type horizontal boring and milling machines, has been introduced by WMO Machine Tool Corp. The essential difference between the P and K versions is that the latter offers an additional column longitudinal travel axis (W) facilitating the use of angular milling heads and other accessories mounted on the headstock. Both models, Cutmax 2FT P and K, offer 4-3/4" spindles powered by variable frequency, 41-HP main AC spindle motors developing an infinitely variable spindle speed range of from 20 to 3,000 RPM. The basic column cross travel (X) is 118" and can be increased to any length in 39" increments. Headstock vertical travel (Y) is 78" or optionally 98". Spindle longitudinal travel (Z) is 23.6". The K version additionally offers column longitudinal travel (W) of 31". All axes are also driven by AC variable frequency controlled servomotors providing a high degree of reliability and resulting in very low maintenance requirements. The Cutmax 2FT P and K design has a wide, stable bed for the X axis. A double pinion anti-backlash combination with a precision rack and Heidenhain linear provides smooth, precise feeds for accurate contouring in the X axis. A newly designed headstock has a nitrided precision boring and milling spindle assembly. The milling sleeve is supported by precision tapered roller bearings. A three-staged, hardened and ground gearbox supplies quiet, high torque power transmission and the stepless speed range of 20 to 3,000 RPM makes available the most useful speeds for a range of boring and milling applications. The head-stock gears and spindle bearings are thermally stabilized through a thermostatically controlled oil refrigeration system. In the P model, the (Y) and (Z) axes are moved through hardened and ground ballscrews and double recirculating ball nuts pre-loaded to eliminate backlash. In the K version, the (W) axis is also moved through a hardened and ground ball screw and nut configuration. The Cutmax 2FT P and K are equipped with the new Heidenhain TNC 415 CNC which offers a simple conversational programming language or standard ISO format (G Code). A variety of rotary tables, with or without slides and floor plates, are also available with these machines. Automatic tool changers are offered with 40, 60 or,80 tool capacities.
