The difference between high-speed punch press and lathe

       Simply analyze the difference between high-speed punch press and lathe from four aspects. High-speed punch press and lathe are both semi-pillar industries of mechanization, especially high-speed lathes that can perform cold punching, composite mold pressing, numerical analysis and intelligent recording, which have a wide range of applications in the stamping industry. Different structures The lathe is mainly composed of the spindle box/headstock box (the spindle includes the spindle box, spindle, bearing), feed box/tool box (main feed, auxiliary feed, screw, screw nut, handwheel), screw and polished rod, slide box, tool holder, tailstock, headboard, cooling device and other structures. The high-speed punch press is mainly composed of cast iron or steel plate bed, slider, crankshaft, camshaft, connecting rod made of high-strength steel, feeding mechanism composed of feeding belt and feeding roller, control system controlled by electronic controller and other structures. Differences in machine tool bed materials The bed materials of lathes are generally made of steel with good toughness and high tensile strength, cast iron that reduces mechanical chord effect, and alloys with low density and light weight. The bed materials of high-speed punch presses are generally made of integrated special cast iron alloys. The bed materials of high-speed punch presses focus on high rigidity and shock resistance. This is because their processing environments and processing requirements are different. For example, high-speed punch presses need to run at high speed for a long time and generally have high standards for the accuracy of finished products. This requires the bed to have certain rigidity and shock resistance to reduce the problem of large workpiece accuracy errors caused by vibration during the punching process. Example: Clothing pocket metal clip label clip tail clip stainless steel copper tail clip clothing accessories high-speed precision punch press, a press with strong stability can ensure that the tooth shape on the tail clip is high and uniform, with good consistency and beautiful finished products. The working principles of the two are different The work of a high-speed punch press is generally that the slider moves up and down. After the material is cut out and the hole is punched, it is squeezed again. When the slider moves upward, we can see the formed material, which relies on the motor to drive the flywheel, and then uses the inertia of weight to complete a series of stamping production tasks. For example, punching two-foot nails, manganese steel shoe flower buckle shoe fixing accessories Iron foot nail high speed precision punch press also operate in this way. The core of lathe processing lies in the driving force of the spindle, which is responsible for driving the workpiece to rotate, while the realization of cutting processing depends on the coordinated work of the fixed tool holder and the movable tool holder. The fixed tool holder firmly carries the tool to ensure the stability during the cutting process, while the movable tool holder flexibly adjusts the position and angle of the tool according to the processing requirements to achieve precise cutting operations. Different work contents Lathe processing can be from simple cylinder processing to complex workpieces. Lathe mainly processes various plane and curved surface graphics such as cylinder, cone, sphere, tooth, thread, etc., and processes partial three-dimensional parts with complex changes in height and thickness of three-dimensional arc; high-speed punch press mainly punches holes and curves in metal coils. Such metal coils are generally not thick, especially small precision parts of high-precision internal parts. Thin metal coils are usually selected, and thicker workpieces are commonly used for refrigerator, television, washing machine shells, car seats, car doors, car front hoods, aircraft wings, etc. In summary, the above is part of the difference between high-speed punch press and lathe. If there is a difference, then the applicable processing conditions will also have certain different contents. It is a wise choice to choose the right machine equipment for efficient production.
