Roll Etching Machine
Roll Etching Machine
MEC Shot Blasting Equipments Pvt Ltd offers a Roll Etching Machine. The rolls are etched for generating desired surface roughness so that the sheets being rolled out can have inbuilt roughness to facilitate proper bonding of paint. During the rolling process, the roller looses the surface roughness due to friction so it becomes essential to etch the rolls periodically for maintaining desired roughness on steel sheets. The rolls being of harder nature, pressure type abrasive blasting machine using aluminium oxide, chilled iron grit of 12-25 mesh or steel shots of coarser grade are quite popular. In order to blast the roller’s barrel, gun reciprocation and job rotation movement is featured in the machine. The job is loaded/unloaded outside the cabinet on the motorised work car placed on track extension. Fabric bag type dust collection system is incorporated to keep the dust emission level within permissible limit. It is very important that roughness should be uniform so media separation/classifier is incorporated for sorting out the broken or uneven shots. This particular machine can be used with different shot sizes for getting different Rz/Ra values. The blasting equipment is featured with motorised workcar with motorised job rotation facility. The roll is loaded outside the blasting cabinet on workcar which moves on track extension. The blasting nozzle reciprocates while job rotates in blasting cabinet. The operator is to simply load and unload the job. The abrasive recovery is automatic and fabric bag type dust collection system is incorporated to keep the dust emission level within permissible limits.
