PL414318A1 - Machine for trimming the excess peripheries of plastic products, protective chamber of the fixed guide and method for processing plastic products - Google Patents

Abstract

A machine for cutting excess edges of plastic products, including a rotary table (3) on which the workpiece (1) is fixed, in a certain position, the machine also includes a cutting tool that cuts the edge of the product during its rotation on the table. The machine is adapted to implement learning and machining cycles, with each learning cycle including turning the table (3) by an angle? of at least 360 ° and each machining cycle includes table rotation by the same angle?, and the machine further includes a movable guide arm (2) coupled during the learning cycle with a movable measuring tip (5) cooperating with the moving periphery of the product (1), while during the machining cycle, coupled with a cutting tool cutting the product rim (1), and an electronic control system, coupled with the guide arm (2) and rotary table (3), adapted to track the movement of the measuring tip (5) and record the shape of the rim on this basis product (1) during the learning cycle and to control the movement of the guide arm (2) and table rotation (3) based on data recorded during the learning cycle, so that the cutting tool travels along the shape registered during the learning cycle during the machining cycle. In addition, the application contains a method of processing plastic products using a machine and the construction of a protective chamber for the machine guide.
