Operating the lathe with electric appliances inside the mold industry
The bed and the column of the machine tool have high rigidity, the v-shaped flat Guide Rail is directly grounded on the bed body, and the cross slide plate is wider and can bear heavy load; the working fluid flow path is also arranged in the column to enable the working fluid to be therein. Constant circulation, maintaining the thermal stability of the column. The water temperature in the working fluid tank can be controlled at 20 ± 0.5 ° C. The lower arm, the guide and the workpiece are all immersed in the working fluid tank and subjected to continuous cooling. The temperature can be kept constant during long-time high-power cutting. The wire-traveling system uses a DC servo motor instead of the original magnetic powder clutch, so that the running speed and tension of the wire are more stable. Originally, the machine tool used the belt conveying mechanism to realize the wire. During the wire feeding process, the wire would form a dent on the belt to cause damage; at the same time, the wire diameter also needs to be replaced with a new belt. The current wire-traveling mechanism is to make the wire electrode swing laterally on the belt, thereby improving the original condition and extending the service life of the belt to about 1000 hours. This series of products adopts Micr.surf micro-precision pulse power supply, which can cut workpieces up to 100mm thick, and the surface roughness of the machined surface can reach Raom. The configured synthetic diamond wire drawing mode guide has smooth rounded inner hole and import and export. The rounded chamfer and the gap between the wire and the wire are zero. Regardless of high pressure flushing, strong discharge, or lateral force generated by the inclination of the wire, the center position of the wire is not changed. After compensating for the difference between the contact position at the exit of the guide and the cutting speed at the tapered end, the angular error in the 30. taper range can be less than 31, and the surface roughness is lower than Rao3m. If a high-peak ultra-narrow pulse width variable polarity pulse power supply is used, the material in the discharge is vaporized and thrown out to remove most of the heat, so that the heat affected layer of the workpiece processing surface becomes shallow. The variable polarity pulse with an average voltage of zero can cause the oH-ion in the machining fluid to oscillate in the gap and no longer erode the surface of the workpiece, so that the surface of the workpiece after processing has no micro-cracks and poor surface caused by electrolytic corrosion. Another new product from Swiss Charmilles is the R.bofil290P precision CNC slow wire cutting machine. The machine can process the largest workpiece size of 85ommX500mmx200mm, the maximum workpiece weight is also 500kg, the x, Y and z axis strokes are 40Omm, 250mm and 20Omm respectively, the u and v axis strokes are 400mm and 250mm respectively, and the cutting inclination is 300. /200m high, the cutting speed can reach 280mm2/min when the wire diameter is 0.3mm, and the X, Y, z, U and v axes all adopt the grating ruler as the measuring component of the full closed-loop control, even if the lead screw is worn. Will affect the positioning accuracy. If the cT-Ex-port programming expert system is configured, the technical requirements of the workpiece surface can be input through the man-machine dialogue. For priority sequences of speed, accuracy and surface roughness, the expert system automatically calculates the most accurate electrode wire offset from the optimal set of parameters in thousands of machining standards to form the geometry of the part. The machining program with matching shapes and different program types are connected in turn to form a program that can run continuously. After the corner precision expert system is configured, the parameters of the workpiece, the wire material, the thickness of the workpiece and the angle of the workpiece can be automatically adjusted to reduce the deflection of the wire to prevent the overcut formation accuracy drift at the corner. The LNIw energy-saving power supply can save 40% energy. The HcKx series CNC electric discharge wire cutting machine introduced by Hanchuan Machine Tool Co., Ltd., such as medium-sized inch type 0, has a table size of 85Ommx500mm, the maximum workpiece size is s00mmx50omm, and the maximum processing thickness. It is 300mm, the maximum workpiece weight is 320kg, the x, Y and z axis strokes are 400mm, 500Inm and 250Inm. The positioning accuracy of x-axis and z-axis is 0.01smm and 0.oZmm respectively, and the guide wire wheel u and v-axis stroke are both 35m (17.smm), pulse equivalent of 0.001m, processing surface roughness Ra2.
