Suitable for a range of metal alloys, die casting has the following advantages:
Saving cost, not only in the part price itself but also in the overall cost of production.
Produces complex parts to net shape, reducing secondary machining
High-speed production compared to other manufacturing processes
Die cast parts are durable and have a long service life
Produces components with attractive, high-quality surface finishes
Produces a broad range of shapes and surface textures
Variable wall thicknesses
Simplifies the assembly process by integrating fastening elements
Fewer steps from raw material to finished part
Tighter tolerances

Servo control mode to classify CNC machine tool. (1) open loop control CNC machine tool The feed servo drive of this kind of machine tool is open-loop, that is, there is no detection feedback device. Generally, its driving motor is a stepping motor. The main feature of stepping motor is that every time the control circuit changes the command pulse signal, the motor will rotate a step angle, and the motor itself has self-locking ability. The drive circuit is controlled by the pulse distributor, which controls the coordinate displacement by changing the number of pulses, the displacement speed by changing the frequency of pulses, and the direction of displacement by changing the distribution sequence of pulses. Therefore, this control mode is characterized by convenient control, simple structure and low price. The command signal flow from the CNC system is unidirectional, so there is no stability problem of the control system, but because the error of the mechanical transmission...
Because the pitch (or lead) of the thread is specified by the drawing, the key to choose the cutting parameters when turning the screw thread is to determine the spindle speed n and the cutting depth AP. 1) SELECTION OF SPINDLE SPEED TO DO SCREW THREAD TURNING According to the mechanism that the spindle turns 1 and the cutter feeds 1 lead when turning the thread, the feed speed of the CNC lathe is determined by the selected spindle speed. The thread lead (which is the pitch when the thread is single head thread) instructed in the thread processing program section is equivalent to the feed speed VF VF = n f (1) expressed by the feed rate f (mm / R) From Formula 1, it can be seen that the feed speed VF is proportional to the feed amount F. if the spindle speed of the machine tool is selected too high, the converted feed speed will greatly exceed the rated feed speed of the machine tool. Therefore, when selecting the rotation speed of the main shaft for turning the threa...
In Metal parts machining works, screw thread (tapping) be required. The screw thread is mainly divided into: connecting thread and driving thread For connecting thread , the main machining methods are: tapping, threading, turning, rolling, etc. For transmission thread , the main machining methods are: rough and fine turning – grinding；whirlwind milling – rough and fine turning , etc. CNC turned screw thread part The following describes the various screw machining methods: THREAD CUTTING Generally, it refers to the method of machining thread on workpiece with forming tool or grinding tool, mainly including turning , milling, tapping, threading, grinding and whirlwind cutting, etc. THREAD MILLING On the thread milling machine, the disc milling cutter or comb milling cutter is used for milling. Disc milling cutter is mainly used for milling trapezoid external thread of screw rod, worm and o...
