Internal Grinding

In conventional grinding small wheels necessitate very frequent dressing and this has meant that there has long since been a search for a more suitable abrasive. Vitrified CBN has been the answer to many problems in this difficult area of internal grinding, most especially for production grinding setups. Using Molemab Vitrified CBN can mean increases in dressing cycles up to 100 fold accompanied by improved surface integrity, better dimensional tolerance and significantly reduced cost-per-part. Due to an extensive home market in this area Molemab has focused on this sector and has developed a world class product.  Typical applications include compressor and pump parts, bearing races, injection nozzles, hydraulic lifters, gear bores and many others. Typical grinding machines include Voumard, UVA, Nova, Overbeck, Ex-Cell- O etc.
