(1) First use the Φ0.20mm cutting wire to process the template hole to the required size, and the inner corner part to R0.15mm.
(2) Demagnetization, shutdown.
(3) Replace Φ0.10mm filaments. Move the wire cutting wire to the unused position. If the conveyor belt is used in all three positions and the feeding of the filaments is not effective, replace the new conveyor belt.
(4) Re-centering. Point-type support enables the precise positioning of the lower deflection point of the cutting wire to precisely guide the cutting wire. When the diameter of the cutting wire is Φ0.20mm, find the center at point b, when the diameter of the cutting wire is Φ0.10mm, find the center at point a, |ab|=|bo|-|ao|=0.1 〖KF ( )2〖KF〗〗-0.05 〖KF()2〗 〖KF〗=0.0707mm.
Therefore, the coordinate value of the center of the φ0.10mm replaced filament should be different from the original central coordinate value by approximately 0.0707mm.
(5) Modify the corner radius of the graphics, reprogramming, avoiding the contour of other holes, and trim the corner radius of the hole to R0.07mm.
(6) Machining sequence of multi-holes die, fixed plate, and discharge plate Multi-hole dies, fixed plates, and unloading plates take into account the influence of residual stress and processing heat during the processing of each type of hole. Deformation, so in the actual production of the use of the same order of the hole processing method to ensure the consistency of the position of the hole shape deformation, thus ensuring the die, the fixed plate, and the plate hole of the coaxiality of the discharge plate.
The walking wire cutting machine has high processing precision and strong functions, but the processing cost is high. To make full use of the role of the machine tool and create a good economic benefit, it is necessary to perform reasonable processing technology analysis and technical performance analysis on the workpiece to fully understand the structure of the machine tool. Performance and mastery of machine tool operation skills, the rational selection of water parameters and electrical parameters, reducing the broken wire in the process of processing, in practice continue to sum up lessons learned, so as to maximize the potential of machine tools, improve production efficiency.
The Oil Control Valve (OCV) is a a critical part used in every engine that is fitted with variable valve technology (VVT). A single control valve will regulate the supply of oil to a designated VVT hub, to advance or retard the timing by altering the camshaft angle position. Controlled by the ECU, the OCV receives electrical signals, instructing it to adjust the oil flow as required, in accordance to current driving conditions.
