Locking fasteners, nut, bolts and washers requires smoothness, free from burrs and required degree of surface roughness for zinc / chrome plating.
Flaws, cracks etc. more over the flatness and surface roughness is also important to be maintained for fasteners. This increases the critical requirement of abrasive blasting on job.
Earlier this was achieved by 7 tank process which has been now against the pollution norms.
MEC SHOT has developed automatic air operated blasting machine for the de-burring and surface preparation of Locking Fasteners for consistency in repeatability. This abrasive blasting machine is featured with rotating Tumble Basket and fixed with gun oriented at different angles depending on the job profile.
The machine works on the suction principle of abrasive blasting. The lifted abrasive gets mixed with the compressed air in the blast gun to strike the job to be cleaned. The locking Fasteners are loaded / unloaded on revolving Tumble Basket. The Tumbling Fasteners get blast cleaned by fixed gun. The abrasive get recycled automatically in twin cyclones for fine media separation and transferred abrasive from storage hopper supply abrasive continuously and un-interrupted blasting operation. The dust generated during the blasting operation is trapped in pleated bags of dust collector and clean air is let out in atmosphere thus keeping the environment eco-friendly.
