Danobat-Overbeck internal, external and face grinding ID 600 grinding machine is MACH highlight

Key features of the machine include the fact that the bed is made in a single block from natural granite, offering optimum thermal and dynamic stability, which is a basic prerequisite for achieving the highest possible accuracies and surface finish during grinding operations. All axes are equipped with linear motor technology, with the motors for the rotary and swivelling movement, as well as the drives for linear movement, featuring independent cooling systems. The spindle on the workhead uses a direct drive as well and may be equipped, depending on application, with a magnetic, power clamping, or manual chuck. True to Danobat's philosophy, the machine is designed with fixed or rotating dressing systems for the use with standard or CBN grinding wheels. The central element on the machining side is its four-spindle turret with direct drive and resolution of 0.0001° for the highest accuracies. In this particular version, the spindle turret has been equipped with a total of four internal grinding spindles to perform internal, external, and face grinding operations. The major mechanical components of the machine, such as grinding wheelhead, workhead, turret, and dresser, were preassembled in a room designed for that purpose, ensuring a dust-free environment with optimum climate conditions. The control and machining processes are supported by Siemens 840 D SL (Solution Line) CNC, with the machining programs developed by Overbeck. Via Danobat-Overbeck's in-house programming service, the machining programs can be adapted to the requirements of individual customers. ID 600 machine can feature process monitoring via acoustic emission for accurate control of the grinding and dressing functions. A remote diagnosis function via internet and/or modem is also included. Depending on the specific application, the ID 600 may be equipped with a number of various different options, such as, for instance, a module for grinding non-round parts. Due to the rather large travel on the X and Z axes, the machine may be used for a multitude of applications. Moreover, the separation of the X-axis from the Z-axis permits a considerably more compact and rigid construction. Using the corresponding solutions for automation and peripheral equipment - automatic loading and unloading systems, in-process measuring controls, and independent cooling and lubricating systems - the machine may easily be incorporated into fully automatic production sequences in support of a wide range of applications, such as the grinding of chuck components, machine components, gears, bearing rings, to name but a few.
