Shenyang CNC machine tool manufacturing | runwei machine tool price is reasonable

  CNC machine tool is an automatic machine tool equipped with program control system, which can make the machine tool act and process parts according to the programmed program
It integrates relatively new technologies such as machinery, automation, computer, measurement, microelectronics, and uses a variety of sensors
The sensors used in CNC machine tools mainly include photoelectric encoder, linear grating, proximity switch, temperature sensor, Hall sensor, current sensor, voltage sensor, pressure sensor, liquid level sensor, resolver, inductosyn, speed sensor, etc
, which are mainly used to detect position Linear displacement and angular displacement, velocity, pressure, temperature, etc The inductosyn installed on the CNC machine tool is made by using the principle that the mutual inductance of two planar windings changes with different positions
Its function is to convert the angular or linear displacement into the phase or amplitude of the induced electromotive force, which can be used to measure the linear or angular displacement
According to its structure, it can be divided into linear type and rotary type
The linear inductosyn is composed of a fixed ruler and a sliding ruler
The fixed ruler is installed on the machine bed, and the sliding ruler is installed on the moving parts and moves with the workbench; The stator of the rotary inductosyn is a fixed disc and the rotor is a rotating disc
Inductosyn has the advantages of high precision and resolution, strong anti-interference ability, long service life, simple maintenance, long-distance displacement measurement, good processability, low cost and so on
Rotary inductosyn is widely used in turntables of machine tools and instruments and various rotary servo control systems When machining parts on CNC machine tools, the following principles should be followed:   1
Select parts suitable for processing on CNC machine tools 2
Analyze the drawings of the processed parts, and clarify the processing content and technical requirements 3
Determine the origin position of the workpiece coordinate system
The origin position is generally selected at the intersection P of the right end face of the workpiece and the spindle rotation center, or it can be set at the intersection o of the spindle rotation center and the left end face of the workpiece 4
When formulating the processing process path, we should consider the position of the starting point of processing, which is generally the position of the end of processing
The starting point should be convenient for checking and clamping the workpiece
We should consider the rough turning, semi finishing turning and finishing turning routes
On the premise of ensuring the machining accuracy and surface roughness of parts, we should complete the processing of parts with relatively few feeding routes as far as possible, shorten the processing time of single parts, and consider the position of tool change points, The tool change point is the position of the tool holder for automatic tool change during the machining process
The selection of the position of the tool change point should consider that there is no interference during the tool change process, and the tool change route should be as short as possible
The starting point of machining and the tool change point can be the same point or not 5
Select cutting parameters
In the process of machining, the reasonable spindle speed, feed speed and cutting depth should be selected according to the accuracy requirements of parts 6
Reasonably select tools
According to the shape and surface accuracy requirements of the machined parts, select the appropriate tool for machining 7
Prepare the special NC machine tool processing program, debug the processing program, and complete the part processing Horizontal machines that generally emphasize fast tool change have several characteristics:   1
The cutter arm of the automatic tool change system of the NC machine tool machining center is short 2
The cutter arm cannot be in a straight line 3
The two knives may be perpendicular to each other 4
The cam box is small and movable
Its main purpose is to make the moment of inertia of the movable part small when changing the tool, so as to achieve the purpose of rapid tool change
This technology includes the setting of tool magazine, tool change mode, tool change actuator and the structural characteristics of high-speed tool machine About the main components and application characteristics of CNC machine tools, we will bring you the following analysis:   1
Tool rest of CNC machine tool   　　  The secondary device of the special machine tool can fix the tool and index the tool, so that the tool is positioned in the direction perpendicular to the spindle, and complete the cutting in the section direction together with the z-axis servo motor 2
Control panel   The control panel includes CRT operation panel (to execute the input / output of NC data) and machine tool operation panel (to execute the manual operation of machine tool) 3
Headstock   The structure of the spindle box of the NC machine tool, the rotation of the spindle servo motor is sent through the belt pulley to the speed change gear in the spindle box, so as to determine the specific speed of the spindle
A clamping chuck is installed at the front and rear of the headstock, where the workpiece can be clamped 4
Spindle servo motor   The spindle servo motors of CNC machine tools have AC and DC
DC servo motor has high reliability and is easy to control torque and speed in a wide range, so it is widely used
However, in recent years, small, high-speed, more reliable AC servo motor as the development achievement of motor control technology is more and more used by people 5
Clamping device   This set of device of CNC machine tool automatically controls the opening / closing of jaws through hydraulic pressure 6
Reciprocating carriage   A tool holder is installed on the reciprocating carriage, and the tool can realize the direction positioning and movement of the spindle through the carriage, so as to complete the cutting in the length direction together with the z-axis servo motor China's machine tool industry faces four major constraints in accelerating its transformation
At present, China's CNC machine tool technology is relatively large, and it can only achieve five axis linkage
According to relevant people, the five axis is still the main component of the show
Almost all the five axis and above are imported, and there is a very big gap between the multi-point linkage technology and the foreign technical level
The interstellar competition in the domestic market is intensifying
Due to the shrinking market of medium and low-end CNC machine tools and excess production capacity, as well as the influx of foreign products at low prices, the market competition will further intensify
Since the products have been dependent on imports for a long time, domestic products are facing the severe challenge of interstellar competition About the processing principles and main component types of CNC machine tools, runwei machine tools will introduce you here today
