Turning centre machines large, long
parts
A 37kW turning centre with an 11kW milling spindle provides the ideal solution for companies machining long, large diameter components particularly found in the aerospace and oil industries.
Yamazaki Mazak's CyberTech Turn 4500MT turning centre provides the ideal solution for companies machining long, large diameter components particularly found in the aerospace and oil industries The CT4500MT combines the power of a 37kW, 2400 rev/min spindle, which has a massive 326kgf/m (2360 ft.lb) of torque, with maximum machining diameter and length of 860mm and 3048mm respectively

Yamazaki to stage 'EMO Encore' for UK buyers
UK buyers and specifiers of machine tools who were unable to attend the EMO exhibition can view and assess new Mazak machine tools at Yamazaki Machinery, Worcester, January 29-February 1.
This powerful turning centre is also equipped, as standard, with an impressive 11kW milling spindle that is equal to many machining centres.
The large upper turret of the CT4500MT has capacity for twelve, 32mm square shank tools and can also accommodate boring bars with shanks up to 50mm diameter.
A further plus point is the fact that rotary tools can be located in any of the turret positions and productivity is boosted by the use of random, shortest path, non-lift indexing, which is achieved in a time of 0.4 seconds.
Additionally, two boring bars with 80mm diameter shanks and up to 1000mm in length can be located in the boring bar stocker.
This feature facilitates the machining of deep bores without the need for time-consuming manual intervention.
The lower turret provides an additional eight positions for OD tools and can be used simultaneously with the upper turret to reduce cycle times through balanced cutting or by combining OD and ID operations.
Furthermore, integral to the CT4500MT is the servo-driven tailstock, which simplifies setup and thrust settings.
The position of the tailstock is recognised by the Mazatrol 640MT Pro CNC, and both its position and thrust settings are controlled by M-code functions.
Confirming the CT4500MT's suitability for the offshore industry is a choice of spindle bore diameter.
As standard, the machine has a 132mm bore and options are available for 185mm, 275mm and 320mm if required, with either a 305mm or 381mm bore through the chuck.
Yamazaki Mazak has also developed advanced threading software that includes canned cycles for the machining of metal seal threads and re-threading functions.
Finally, for a machine of this size agility has not been compromised and rapid traverse rates in the X and Z axes are 24m/min and 30m/min respectively.
The contouring capability, so often required on aircraft and oil industry components, is enhanced by the C-axis, which has a minimum programming increment of 0.001 deg. Request a free brochure from Yamazaki Mazak UK ...
