Cutting powder scattering prevention device of crankshaft milling machine

摘要

It is prevented from scattering around when the cutter is stopped by the centrifugal force attached to the inner surface of the cutter drum.;The work 3 held at both ends by the chuck 4 is cut by the cutter 11a mounted on the rotating cutter drum 11 and the work 3 is cut by the cutter 11a, (B) of the machining unit (5) in the vicinity of the above-mentioned rest arm (12a) in the vicinity of the machining portion of the machining unit (5) by clamping and supporting the vicinity of the machining portion of the crankshaft by a rest arm (12a) A main cover 16a which holds an opening 16c having a diameter sufficiently larger than the outer diameter of the chuck 4 in the main cover 16a and a main cover 16b mounted on the opening 16c of the main cover 16a, Preventing cover 16 is provided to the auxiliary cover 16b having an opening 16e slightly larger in diameter than the outer diameter of the cutter 11a are stopped, the centrifugal force applied to the inner surface of the cutter drum 11;Even if the cutting powder falls due to its own weight, it can be prevented from scattering around by the auxiliary cover 16b.
