Screw slide table TV series

motorizedmechanicalprecision

Linear precision tables, modular type for assembling on X,Y,Z and on multiple axes. Motor-drive with CNC control, motion on cross roller rails and ballscrews. Considerable stiffness and load capacity. The tables of the TV series are used for the realisation of positioning systems, for general use in the industrial auto- mation and for light mechanical operations. The admissible loads shown in the charts must be considered as maximum theoretical values both for the rails system and for the thrust load on the drive-screw. For a correct use of the tables as to accuracy, stiffness, lifetime and safety of the system, it is necessary to consider the appropriate safety coefficients. For this purpose, see the charts and calculation methods in the specific chapters in the ROSA SISTEMI Catalogues for rails and drive screws Although the maximum admissible speed for the tables is up to 40-50 m/min, these values will never be reached considering the short stroke of the tables, the necessary accelerations and the reduced pitch of the ballscrews. From the speed standpoint the limitation is given by the ballscrew, from which the admissible values are derived. Maximum rotary velocity of the ballscrew (n) 2400 n/min Screw pitch (p) in mm The ballscrews and rails have been correctly lubricated during assembling, i.e. oil is used for the rails and grease for the ballscrews. However, the conditions of the system lubrication must be checked from time to time and, if necessary, the initial conditions restored. The TV2/TV3 tables permit the installation of centralised oil lubrication systems. The tables are supplied together with the specific documentation about the recommended lubricants.
