This CMZ TA 15 MS – 640 is a used CNC lathe — sometimes referred to as a turning centre — built for precision turning combined with live milling capability across two spindles. CNC lathes of this type are used in high-volume and high-precision component manufacturing, handling turned and milled features in a single setup. CMZ is a Spanish machine tool builder with an established reputation for CNC turning centres serving the automotive, aerospace, and general engineering sectors.
The machine is configured as a slant-bed twin-spindle lathe with driven tooling, controlled by a Fanuc 32i-TB CNC unit with a 15-inch touchscreen and iHMI interface. The main spindle runs to 6,000 rpm and accepts bar stock up to 52 mm diameter through a DIN 6343 collet chuck holder (Autoblok VNK 130-52 hydraulic cylinder, bore diameter 61 mm). The sub-spindle, used for pick-off and second-operation work, runs to 4,500 rpm with a maximum power of 14 kW, and is fitted with a Hainbuch Spanntop Nova AXFIX 52 collet system.
Turning capacity is defined by a maximum swing over the bed of 760 mm, a maximum diameter over the cross-slide of 600 mm, and a maximum turning diameter of 460 mm. The distance between centres is 730 mm. Axis travels are 310 mm in X and 640 mm in both Z and B. Rapid traverse rates on all axes are 30 m/min.
The 12-station automatic turret carries 12 live tool positions. Driven tools reach 12,000 rpm with a peak power of 11.3 kW (8.1 kW continuous in S1 duty). A Renishaw HPRA probing arm is fitted for in-process measurement. Coolant provision includes through-spindle coolant and a high-pressure pump at 6 bar. Chip management is handled by a rear-mounted double-chain chip conveyor.
The machine is supplied with an IEMCA Boss 552/32 HD Heavy Duty bar feeder for automated loading of bar stock up to 32 mm diameter. Machine weight is approximately 6 tonnes. The hour meter records 14,536 total machine hours and 5,000 cutting hours, indicating that the machine has seen active but measured productive use. It was manufactured in 2017 and is currently located in France.
