CMZ’s TB range of turning centres features an extremely rigid cast iron frame fitted with linear guide-ways, allowing accelerations of up to 1G and rapid traverse speeds of 30m/min.
Spanish machine tool manufacturer, CMZ, said at the UK’s MACH 2008 machine tool show last week that its TB range of turning centres features an extremely rigid cast iron frame that is machined, in-house by CMZ The machines have linear guide-ways, allowing accelerations of up to 1G and rapid traverse speeds of 30m/min
fThe TB range c omprises four models, including 46mm and 67mm bar capacity machines, with and without driven tooling.
CMZ also said that the TB series is extremely popular as a bar-fed machine, while it also offers a maximum turning diameter of 340mm when using a 210mm chuck, which is available on the 46mm and 67mm machines.
The TB machines can now be fitted with a gantry loading robot for automated billet and shaft loading and unloading.
Integrated, oil-cooled spindle motors give increased accuracy and improved surface finish, as well as faster acceleration and braking times and they also contribute to the machine’s extremely compact design.
The whole machine occupies only around 1.6m3.
The fast, non-lift, 12-station turret features a hydraulically clamped Curvic coupling for strength and accuracy and can rotate 180 deg in just 0.5s.
The turret is clamped and unclamped while it is traversing into position, giving effective tool change times as fast as 0.15s.
Separate servo motors are fitted for turret rotation and driven tooling.
The machines are fitted with the latest Fanuc 32 series CNC, with Manual Guide i conversational programming included as standard.
