Hard rail machine is slower, but more rigid, anti-collision, mainly used for heavy cutting, mold. The linear rail machine is fast and has better accuracy. It is mainly used for light cutting and products. Relatively speaking, there is no hard rail machine with a long life. Generally, BT40 has more bed rails and BT50 has more rectangular rails. Now many people buy CNC horizontal lathes to choose two lines and one hard, because this can increase the speed and increase the cutting force, and it is cost-effective. Why does CNC horizontal lathe drilling fast? Due to the rapid development of the domestic 3C industry, CNC horizontal lathes have an increasing market share. CNC horizontal lathes have the characteristics of high speed, high precision, high finish, and high efficiency, which are especially popular with users in the 3C industry. Cnc Machining efficiency is money, and many friends have a question, why is the CNC horizontal lathe drilling fast? Today we will talk about why the horizontal center drilling is fast.
The method often used in CNC horizontal lathe control engineering is: first establish a simplified model that is as linear as possible, and then obtain the approximate characteristics of the system on this basis. If necessary, use more complex models for further research. This step-by-step approximate research method is a commonly used method in engineering. The mathematical model of the CNC horizontal lathe control system is not all rich control systems that can adopt linearization processing methods. For some systems with strong nonlinearity, it is better to use nonlinear research methods to deal with them.
The CNC horizontal lathe is mainly composed of grinding wheel frame, head frame, bed, workbench, tail frame and other cnc machining parts in the production process. The bed of the CNC horizontal lathe adopts large round holes and shark fin-shaped ribs. After long-term use , The machine tool has good dynamic and static stiffness. The working table of the CNC horizontal lathe can be divided into upper and lower table to grind the conical surface. The machine bed and the guide rail of the working table adopt plastic guide rails, and the friction coefficient is small. The worktable is directly driven by the servo motor to move the ball screw, and the movement is stable and reliable. The linear speed of the grinding wheel of the CNC horizontal lathe is less than 35m/s, and the overall grinding efficiency is relatively high when in use. The grinding head bearing is a three-piece dynamic pressure bearing with a large wrap angle, and the rotation accuracy is high. The movement of the wheel carriage (X direction) is directly driven by the servo motor and the ball screw, with a small resolution of 0.0005mm.
