Combined inverted spindle lathes show
versatility
Two Mazak inverted vertical spindle CNC lathes were shown automatically operating in combination at EMO, demonstrating the exceptional versatility of the machinery and the robot handling systems.
Two Mazak IVS 200 inverted vertical spindle CNC lathes were demonstrated automatically operating in combination at EMO, demonstrating the exceptional versatility of the machinery and the robot handling by simultaneously working on three different workpieces In the demonstration, the two IVS 200's are arranged to machine three different components

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.
Two of the components are machined independently and simultaneously on both machines, loaded via the conveyor system and inverted between the first and second operation by the robot.
A third component is machined on both, one each taking care of first and second operations.
The robot is used to load the conveyor system from three input conveyors and to unload from the output conveyor.

Each workpiece requires different collet sizes and these are automatically changed using the robot to place the next collet onto a pallet on the conveyor system - which carries it to the machine loading system.
At this stage, the spindle deposits the previous collet to an unload pallet and loads the new collet.
In this way, each different size component is introduced into the machining cycle, optimising the use of machining time and demonstrating the versatility of the two machines working in combination with the robot sequencing not only work piece loading but also the available machine time.
The recently introduced Mazak IVS 200 lathe is specifically designed for mass production environments, with high speed and precision in a very compact machine layout.
The vertical, inverted spindle format is designed to minimise both cutting and non-cutting times and to automate loading with minimum operator attendance in medium to high volume batch manufacturing environments.
The spindle, moving in X and Z direction, features an X-axis scale feedback system, cooling systems for key machine components and smooth, consistent chip disposal to provide a combination of high precision and reliable operation over extended periods.
The high mounted chuck and spindle ensures swarf simply falls away from the cutting area, preventing heat retention around the workpiece and creating optimum swarf control.
