C6555 Series Spherical turning lathe:
Spherical turning lathe, is also called ball turning lathe, external spherical surface turning lathe or globe lathe machine. Spherical turning lathe is mainly used for spherical outside surface, inner surface and the ball on shafts machining. The process range of spherical diameter is 550mm - 1800mm.Our company developed the spherical lathe according to the market demand, mainly used for the outer ball of the ball rough machining, finish grinding. It also can be used as a common lathe, such as turning cylindrical, bore, end and so on.
In China, we are the most professional spherical turning lathes manufacturer. Our factory has the best technical support team. The spherical surface turning lathe will be customized according to differernt requirements
Features of steel ball turning lathe:
(1). The lathe bed adopts rectangular guide rails which with the beststability.
(2). The lathe spindle is of high precision which with 3 supportstructure.It can support heavy cutting.
(3). Operation is easy for workers.
(4).The rotary center line of the tool holder intersected with the rotating center line of the workpiece in order to ensure the roundness.
(5).You just need provide your workpiece and we will especially design precision lathe for you.
Application:
Apply to varieties valve balls machining:
