2 CNC ROTARY SURFACE GRINDI. WITH 2-AXIS SIMULTANEOUSLY CON ATTAINS HIGHER ACCURACY AND MUCH HI DYNAMICALLY ACCELERATES SOPHISTICAl WITH COVERAGE FROM SINGLE PARTS TO Step-Grinding Upto 4 steps with High Accuracy and High Speed.Multi-step grinding is one of the big advantages PRG-DXNC series have. CNC 2-axis sumultaneous control enables grinding upto 4 steps, thus so widely expands shape coverage of workpieces. ( l-step ) ( 2-Step ) ( 3-Step ) e===:j ~ E~X~.Simple adustment permits table to incline by ±So or ±3 respectively for PRG-6DXNC or PRG-8DXNC. So best suited to tapered parts with interior convex or concave, or blades..---/_.,, rill I 11 I 1. Il.. J Unique Machine Construction Supporting High Precision Grinding.Novel system is employed for wheel head moving. All our advanced design know-how utilized in our machines line-up of high precision specs are made the most of therein. Our original unique construction uncomparable with the conventional one ensures highly performed, excellent operation..employing permanent grease seal system and also super-precision class angularcontact ball bearing for the wheel spindle, PRG- DXNC is successful in increasingsurface accuracy as well as streamlining troublesome maintenance. Metal bearing is optionally available at request..tarkaite is adopted on slide surface, which therefore leads to stable revolution for long time. In order to keep peripheral speed at the grinding secti on constant table revolution varies synchronously with wheel crossfeed moving from periphery to center, thus crossfeed rate per table revolution is controlledto be constant. / i Our unique wheel head moving system / TARKAIT slide surface Sophisticatedly arranged operation zone CNC ROTARY SURFACE I p)1~~(gl- PRG-6DXNC/PR(
