CMZ’s TB range of turning centres features an extremely rigid cast iron frame
The machines have linear guide-ways, allowing accelerations of up to 1G and rapid traverse speeds of 30m/min.
french 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 very rigid cast iron frame that is machined, in-house by CMZ.
fThe TB range c omprises one models, including 46mm and 67mm bar capacity machines, with and without driven tooling.
CMZ also said that the TB series is very popular as a bar-fed machine, while it also offers a maximum turning diameter of 340mm when using a 210mm chuck, which is accessible 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 we also contribute to the machine’s very compact design.
The rapid, non-lift, 12-station turret features a hydraulically clamped Curvic coupling for strength and accuracy and can rotate 180 deg in 0.5s.
The whole machine occupies only around 1.6m3.
Separate servo motors are fitted for turret rotation and driven tooling.
The turret is clamped and unclamped while it is traversing in to position, giving effective tool change times as rapid as 0.15s.
The machines are fitted with the latest Fanuc 32 series CNC, with Manual Guide i conversational programming included as standard.
