Geminis scnc medium lathes

GEMINIS, scnc 52 ELGOIBAR Spain CNC Medium Series Quality and accuracy BEARINGS ARRANGEMENT ON THE MAIN SPINDLE STANDARD VERSION Rigidity of spindle between these bearings is Ra 240 Kg/μ. GEMINIS lathes GEMINIS describes in this catalog the lathes called SCNC and SCNC-DC of Medium Series. In their design, two agents have been decisive. In one hand, the constructive fittings to requirement of nowadays manufacturings, and in the other hand, the need to get the best easy operation and comfort of worker. Many years of experience manufacturing lathes, in close collaboration with our customers and together with our desire to overcome problems, have made that we are in the vanguard in the manufacturing of this type of machines. We would like to utilize these lines to put our technical department at your disposal, being sure that we will do all our possible to solve any problem that may arise. Due to improvements and continuous progress, this leaflet presents only an actual technical level. This is why all technical datum and drawings can be modified without previous notice. VARIATIONS OF SCNC-DC MODELS WITH REGARD TO SCNC ONES The main difference is that the main motor has continuous speeds variation, so the workpiece rpm are optimal and automatically fitted to the established cutting conditions. SCNC Workpiece weight: and general product Standard maximum weights for turning workpieces are approximate. If working pieces are heavier, these values can be exceeded if we have in mind the necessary security measures.

Motor of SCNC-DC models continuous speed variation after removing its protection. CONTROL EQUIPMENT VERIFICATION AND TESTING According to the user's preferences, the lathe is prepared. According to NF E60-102, DIN standards or similar. red to receive any band and model of Numerical controls presently available in the market. ELECTRIC INSTALLATION Trustworthy and functional. Wiring and devices are according to present prescriptions and easy to buy in the market. The use of easy maintenance elements together with channel wiring and a clear layout by groups according to their functions to be done, bring maintenance downtime to a minimum.
