AUTOMATIC GRINDING MACHINE FOR CORNERS
Machine is composed by:
a) an operating head with pneumatic tension of the abrasive belt, with free belt oscillating fork. b) a carriage for longitudinal handling (machining) of working head, equipped with recirculating ball bearing guides, gear motor and trapezoidal screw and nut transmission. c) a carriage for transversal handling of working head (approach to the piece), equipped with recirculating ball bearing guides, pneumatic cylinder and solenoid valve. d) electrical system consisting of a metal box, containing the inverter for operating head speed variation, a programmable relay aimed at operating head in-and out timing, 2 buttons security system for vice locking, reset button, start button, stop button, emergency push button, and all the necessary components such as relays, contactors, etc. f) base with table support for pieces, with fitting edge “0” on side and front. g) manually adjustable clamp by hand wheel and numerical display, for the width of the piece with fast locking device, The operator acts on the hand-wheel and by means of the digit display edits width value of work pieces; then pieces are placed on the support table in order to be positioned against side and front fitting edges. By pressing the two buttons, pieces are pneumatically clamped. On control panel, operator can select working head feeding and abrasive belt speed, then presses the start button. Working head is operated and moves towards the piece at the desired processing speed, processing the work piece as desired. When machining has been completed, the head stops. From this moment on, operator can unlock the work-piece and insert a new work piece
