Vapour Honing Machine For Crank Pin Of Two Wheeler Automobiles

Mecshot Blasting Equipments has successfully engineered and supplied vapour honing machines for achieving surface finish of 0.8 to 3.0 Ra in microns on crank pins of two wheeler automotives at both sides/end portions of length 10.5 mm with middle portion masked to avoid medias entering lubricating hole. The supplied machine works on suction-induction principle of abrasive blasting. The fine particles of abrasive are suspended in liquid (usually water) and are then pumped into the nozzle as a slurry. At nozzle slurry is introduced into air stream and propelled against job. The equipment consists of wet blasting cabinet duly zinc metallized to prevent rusting, blasting nozzle with glandless pump for slurry feeding, mist collector and necessary controls. Indexing type rotary turntable with rotating satellites with blasting guns are provided. A glandless slurry pump is used to feed the slurry at positive pressure into the blast chamber where the satellite starts rotating at blast station. As the job rotates, blast guns, which are fixed at a station, clean the outer periphery of the crank pin the operator simply loads and unloads the job from satellite. The mist generate during blasting operation is sucked in a mist collector keeping the vision clear.
