gear profile grinding machines ZP I/E
profile grinding of gears
The internal grinding attachment is mounted directly on a large machine column and carries the complete grinding arm including a dressing and measuring unit. The grinding wheel will be dressed by a patented method using the tangential axis of the grinding head and a dressing axis. The CNC dressing device is located directly above the grinding wheel, which allows the wheel to be dressed in its grinding position. This eliminates long dressing paths and at the end, reduces the process times significantly. The grinding spindle is driven by a timing belt. This concept increases the torque on the grinding wheel, allows the grinding spindle to be thermally separated from the motor, and provides a compact design. The strong drive delivers enough power for high material removal also when using large and wide grinding wheels.
Even the basic machines are equipped with coolant filtration unit, dresser, in process measuring system, balancing unit, acoustic emission sensor and comprehensive software for grinding and measuring of involute profiles.
The use of high-strength, vibration-absorbing and durable spheroidal cast iron is one of the key features for the machine accuracy. Further outstanding features are, amongst others, a well dimensioned rotary table with electrical direct drive and hydrostatic bearing for highly accurate positioning, excellent load capacity and almost unlimited lifetime.
