Frequently asked questions
What parts is the MG 560 CNC designed for?
The manufacturer defines the MG 560 CNC for the complete manufacturing of cold swaging rifling mandrels; cylindrical and groove grinding are done on the same machine, between dead centres.
What are the workhead and tailstock features?
The workhead is direct-driven by a torque motor and turns at up to 600 rpm; torque is 85 Nm and the clamping interface ISO-50. A rigid tailstock is provided for high-precision grinding.
What are the grinding spindle and measuring capacities?
The grinding spindle runs at 0–12,000 rpm with up to 11.5 kW and a maximum wheel diameter of Ø 200 mm. The Renishaw LP2 / MP250 probe gives 1–2 µm unidirectional repeatability.
