TR400/2S

TWO-UNIT PNEUMATIC CUT-OFF MACHINE

TR400/2S MACHINE DESCRIPTION

The TR400/2S pneumatic cutting-off machine consisting of two units manufactured by Electro mac Srl is a technologically advanced, innovative machine designed for foundries. Electro Mac Srl was one of the first Italian companies to conceive and manufacture this specific type of pneumatic cutting-off machine which stands out for its great precision, large dimensions and long duration even under very difficult operating conditions. The support structure of the TR400/2S machine is made of electro-welded metal plate. It is enclosed in a sound-proof housing with sound-absorbing panels, two lateral access doors to the housing for replacing abrasive discs, arrangement for dust extraction and double front safety door with a pneumatic opening system. The electrical motor is a three-phase, asynchronous, 2-pole motor, Hp 7.5 220/380/50 Hz., 2,800 rounds/min. and it is driven by wedge belts. The workpiece to be cut is brought close to the abrasive disc by means of two slides driven by a pneumatic cylinder. It is possible to select either the quick or the slow operation mode. These slides are equipped with sliding bearings with a diameter of 40 mm. located on hardened, ground bars, with a hydraulic decelerator (SLOW) and pneumatic vertical clamps mounted on board the slide car for a safe grip of the workpiece. The slide of the TR400/2S pneumatic cutting-off machine supporting the motor is driven by a jack cylinder equipped with an electric motor mod. MA 5B 0.18 Kw. The position of the abrasive discs is constantly updated by means of two photocells. The cutting start point remains always the same, thus avoiding any change in position at the beginning of the cutting procedure resulting from worn abrasive discs and the consequent reduction in diameter. The pneumatic panel is incorporated in the machine supporting structure and includes 9 ISO 5599/1 WAIRCOM MBS 24 V.D.C.bistable electrovalves mounted on suitable bases. The electrical control panel managed by a TELEMECANIQUE PLC mod. TSX 3710 and a cutting-edge technology keyboard enable the operator to manage the machine manually.
