Working principle of slow wire processing

 Slow wire walking, also called low-speed wire walking, is a kind of CNC machining machine tool that uses continuously moving fine metal wire as an electrode to pulse spark discharge on the workpiece to generate a high temperature of over 6000 degrees, ablate metal and cut into a workpiece. The principle of wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge. Since the slow-moving wire cutting machine adopts the method of wire electrode continuous feeding, that is, the wire electrode is processed during the movement, so even if the wire electrode is worn out, it can be continuously supplemented, so it can improve the machining accuracy of the parts and slow the wire. The surface roughness of the workpiece processed by the cutting machine can usually reach Ra=0.8μm and above, and the roundness error, linear error and dimensional error of the slow-moving wire cutting machine are much better t

Hydrostatic guideway of CNC machining lathe

The static pressure slide rail (TTW guide) of the CNC machining lathe transfers the oil with a certain pressure through the throttle to the oil cavity between the sliding surfaces of the slide rail (TTW guide) to form a pressure oil film to float the moving parts , Make the sliding rail (TTW guide) surface in a pure liquid friction state.   CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining c17200   beryllium   copper   and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and lette

Elimination of Gear Backlash in CNC Machining Feed System

Elimination of Gear Backlash in CNC Machining Feed System   The transmission gear in the feed system of the CNC machining machine tool must eliminate the transmission gap between the meshing gears as much as possible, otherwise the motion will lag behind the command signal after each reversal of the feed system, which will affect the machining accuracy (accuracy) ). There are the following two common methods for CNC machining machine tools to eliminate the transmission gear gap.   1. Rigidity adjustment method   The rigid adjustment method is an adjustment method that cannot be automatically compensated for the tooth side clearance after adjustment. Therefore, the pitch tolerance and tooth thickness of the gear must be strictly controlled, otherwise the flexibility of the transmission will be affected. This adjustment method has a relatively simple structure and a better transmission rigidity.   (1) Eccentric shaft adjustment method   As shown in Figure 610, the gear 1 is mounted on th

What are the functions of GPS vehicle positioning system?

What are the functions of GPS vehicle positioning system? The GPS vehicle positioning system implements tracking of one or more designated vehicles. With the movement of the vehicle, the electronic map can be automatically zoomed, so that the target always falls in the window, and the vehicle is tracked according to the tracking priority at the set time interval. Intuitive movement trajectory.

At present, the GPS system has been connected to the whole country and connected with 110 of public security agencies in various places. Even if the vehicle leaves the jurisdiction, as long as it is within the network coverage, it can get timely service. You will receive an alarm at ** time. After receiving the alarm, the monitoring center informs the staff on duty through sound and light alarm, and moves the alarm vehicle to the center of the screen, and displays the coordinate location, attributes, pictures, isomorphism category, occurrence time, etc. of the alarm vehicle to help the police deal with it .

What are the functions of GPS vehicle positioning system?

(1) Query now

After the monitoring center issues an immediate command, the GPS terminal uploads the location information (including longitude, latitude, azimuth, speed, number of satellites, etc.) and status information of the vehicle, person or pet in time.

(2) Remote tracking

The monitoring center can set the GPS terminal on the monitoring software for timing tracking settings, and can set a fixed time to upload the location information and status information. Once the setting is successful, the GPS terminal will upload the requirements of the monitoring center in time according to the instructions issued by the monitoring center Information.

(3) Urgent help

When a driver or an individual wearing a GPS terminal encounters a special situation, he can ask the monitoring center for help through the emergency button. Once the monitoring center receives a distress order, the monitoring center staff can provide assistance or notify the police for assistance.

(4) Historical track playback function

In the historical track playback, the GPS positioning system can check where the vehicle, person or pet is located on a certain day in the historical information, and which route is taken. What is the state of the vehicle at that time, etc.
