The L2 is an extremely versatile machine for high levels of production, regardless of whether you are producing hydraulic control valves, brake callipers, bearing cups or even aeroengine blades.
The roughing capacities of the L2 are sometimes belittled by an external viewer. Is it possible that this small machine can cut rough materials?
With this example we can see what kind of a “monster” is hidden in the L2.
L2 - Specifications
Let's first review the L2 in terms of its specifications:
We started with a 238 x 150 x 70 mm casting block (ISO1083/JS/450-10/S) and carried out heavy-duty machining of this ductile cast iron to demonstrate the machine’s ability to perform:
Fine spot facing
High feed drilling
Stable face milling
Tooling and process
Tooling and process
For the process we used four tools and tried to push the machine to high limits to demonstrate what can be achieved on the real part:
Face mill D50 - ae:45 mm apmax: 5 mm F3500 mm/min
Drill D20 - F1,100 mm/min
Stepped drill D25xD40 - F 460/190 mm/min
M27x2 - F700 mm /min
As you can see, extraordinary conditions can push a machine with a small footprint to the performance of bigger horizontal machining centre.
