What is plunge milling? What is its use in processing?

What is plunge milling? What is its use in processing?

Plunge milling, also known as Z-axis milling, is one of the most effective machining methods for high removal rate metal cutting. For surface machining, grooving and machining with large tool overhangs of difficult-to-machine materials, the processing efficiency of plunge milling is much higher than that of conventional end milling. In fact, when a large amount of metal material needs to be removed quickly, the plunge milling method can reduce the processing time by more than half. ▉advantage In addition, plunge milling has the following advantages: ①It can reduce the deformation of the workpiece; ②It can reduce the radial cutting force acting on the milling machine, which means that the spindle whose shaft system has been worn can still be used for plunge milling without affecting the processing quality of the workpiece; ③The tool overhang is large, This is very beneficial to the milling of the groove or surface of the workpiece; ④It can realize the grooving of high-temperature alloy materials (such as Inconel). Plunge milling is very suitable for rough machining of mold cavities and is recommended for efficient machining of aerospace parts. One of the special applications is plunge milling of turbine blades on a three-axis or four-axis milling machine. This kind of processing usually needs to be performed on a dedicated machine tool. ▉ Working principle When the turbine blade is plunge-milled, it can be milled from the top of the workpiece down to the root of the workpiece. Through simple translation of the X-Y plane, extremely complex surface geometries can be processed. When implementing plunge milling, the cutting edge of the milling cutter is formed by overlapping the profile of each blade, and the plunge milling depth can reach 250mm without vibration or distortion. The cutting motion direction of the tool relative to the workpiece can be either downward or downward. Upward, but generally cutting downward is more common. When plunge milling the inclined plane, the plunge milling cutter makes compound movement along the Z axis and X axis. In some processing occasions, spherical milling cutters, face milling cutters or other milling cutters can also be used to mill grooves, milling surfaces, milling bevels, and milling cavities. ▉ Scope of application The special plunge milling cutter is mainly used for roughing or semi-finishing. It can cut into the concave part of the workpiece or cut along the edge of the workpiece. It can also mill complex geometric shapes, including root cutting. In order to ensure a constant cutting temperature, all shank plunge milling cutters adopt internal cooling. The cutter body and insert design of the plunge milling cutter can cut into the workpiece at the best angle. Usually the cutting edge angle of the plunge milling cutter is 87° or 90°, and the feed rate ranges from 0.08 to 0.25 mm/tooth. The number of inserts clamped on each plunge milling cutter depends on the diameter of the milling cutter. For example, ...
what different is CNC & NC

what different is CNC & NC

NC (Numerical Control, digital control, referred to as numerical control) refers to the use of discrete digital information to control the operation of machinery and other devices, which can only be programmed by the operator. CNC CNC technology application   The development of CNC technology is quite rapid, which greatly improves the productivity of mold processing. Among them, the CPU with faster operation speed is the core of the development of CNC technology. The improvement of CPU is not only the improvement of operation speed, but the speed itself also involves the improvement of CNC technology in other aspects. Because of the great changes in CNC technology in recent years, it is worth a review of the current application of CNC technology in the mold manufacturing industry.       Block processing time and others Due to the increase in CPU processing speed, and CNC manufacturers applying high-speed CPUs to highly integrated CNC systems, the performance of CNC has been significantly improved. Faster and more sensitive systems achieve more than just higher program processing speed. In fact, a system that can process part machining programs at a fairly high speed may also behave like a low-speed processing system during operation, because even a fully functional CNC system has some potential problems that may become limitations The bottleneck of processing speed.   At present, most mold factories realize that high-speed machining requires more than short processing time. In many ways, this situation is very similar to driving a car. Will the fastest car win the race? Even a spectator who watches the car race occasionally knows that in addition to speed, there are many factors that affect the outcome of the race.   First of all, the driver's knowledge of the track is important: he must know where there are sharp turns so that he can slow down appropriately and pass the curve safely and efficiently. In the process of processing molds with high feed speed, the to-be-processed trajectory monitoring technology in CNC can obtain the information of sharp curves in advance. This function plays the same role.   Similarly, the driver's sensitivity to other drivers' actions and uncertainties is similar to the number of servo feedbacks in the CNC. Servo feedback in CNC mainly includes position feedback, speed feedback and current feedback.   When a driver is driving around the track, the consistency of the movement, whether he can brake and accelerate skillfully, has a very important impact on the driver's performance on the spot. Similarly, the bell-shaped acceleration/deceleration and to-be-processed track monitoring functions of the CNC system use slow acceleration/deceleration instead of abrupt speed changes to ensure smooth acceleration of the machine tool.   In addition, there are other similarities between the car and the CNC system. The power of the racing engine is similar to the drive and motor of the...

Basic requirements for motor shafts What are the basic requirements for motor shafts?

Basic requirements for motor shafts What are the basic requirements for motor shafts? (1) Must have sufficient strength. That is to say, under normal load and specified special conditions (such as sudden short circuit, etc.), any part of the shaft cannot produce residual deformation or damage. (2) Must have sufficient rigidity. That is, the deflection of the rotating shaft must be within the allowable range. (3) There should be sufficient difference between critical speed and working speed to avoid resonance.
