Key words:pin hole sleeve,abrasion resistance,45 steel,subcritical quenched,surface treat ment process   Lathe,an important part of the machining,   The diagram ofstructure is Fig.1: plays an important role in the development of indus trial.The CNC lathe is in production for many years and with great success,but compared traditional lathe is still irreplaceable,is important equipment in turner production.Lathe square turret is the impor tant factor to determine the accuracy of turner,but there is an emergence ofthe fault in use which seri ously affects the accuracy,leads to a direct result of the decrease i
