As shown in the machining cycle, with machines that can provide a pressure on tailstock side over kg.1000, even turning with 2 tools working simultaneously, with very high cutting parameters, can be carried out.
LEFT BACK STUB AXLE
This machining is very interesting because it is shown how so special components can be machined with the face driver with no need to study special clamping solutions and machining cycles surely less convenient than machining with the face driver in one set up.
TURNING OF PINION AFTER HARDENING
In these last years, request for hard turning operation is increased. With the face driver with fixed center this operation, that replaces grinding operation and that requires very strict tolerances after finishing, can be carried out.
With the face driver with fixed center in fact, a perfect concentricity and rigidity can be obtained; then, the hard metal driving pins fitted in the face driver, ensure an optimum clamping even on steel hardened up to 63 HRC.
New live centers “2008 serie” have been designed to work with this face driver; they guarantee a very high accuracy and rigidity and are suitable to reach tolerances similar to ones obtained in grinding.
TURNING OF 5 CYLINDERS CRANKSHAFT
Machining on centers, with the face driver with fixed center to get the maximum rigidity even on a so unbalanced component. Material: cast iron
Machining of flywheel side and end side in one set up as shown in the video.
ONE CYLINDER CRANCKSHAFT
This very difficult operation is possible only if using a face driver with fixed center.
As shown in the video, despite the small clamping diameter, even the two diameters in the middle could be worked out.
INPUT SHAFT OF GEARBOX
Using a steady rest, every type of possible vibration during machining of the grooves is reduced as much as possible.
INPUT SHAFT MACHINED WITHOUT STEADY REST
Despite the lenght and the small clamping diameter, it is possible to make machining with the face driver without personalizing the working parameters.
TURNING OF GEAR CASE
After centering, facing and machining of the holes, the component is machined on centers with the face driver and the live center in a single set up.
With this type of machining, all machined parts will be perfectly concentric to holes and centers machined before. Worked material: cast iron.
TURNING AND MILLING Ø 300
Turning and milling operation on CN machine with live tools.
OD turning Ø 300 and then machining of the planes with milling tool.
