In fact, computer gong is a CNC milling machine. In Guangzhou, Zhejiang and Shanghai, a person named “CNC machining center” is an automatic machine tool with program control system. (CNC machine tool) is a short name for computer numerical control, and it is an automatic machine tool controlled by program. The control system can logically process the program with control code or other symbol instructions, decode it by computer, so that the machine tool can act and process parts. The rough blank is processed into semi-finished finished parts by cutting tools.
CNC machining is the machining of CNC machining, which is made by means of CNC tools. CNC index control machine tool is programmed and controlled by NC machining language, usually G code. NC machining G code language tells the NC machine tool which Cartesian position coordinates to use, and control the feed speed and spindle speed of the tool, as well as tool converter, coolant and other functions. NC machining has a great advantage over manual machining. High speed computer gong processing, such as parts produced by NC machining, is very accurate and repeatable; NC machining can produce parts with complex shape which cannot be completed by manual machining. CNC machining technology has been widely spread, most machining workshops have the ability of NC machining. The most common NC machining methods in typical machining workshops are NC milling, CNC car and CNC EDM wire cutting (EDM). The tool for NC milling is called CNC milling machine or CNC machining center. The lathe for NC turning is called the CNC lathe center. The G code of NC machining can be programmed manually, but the machining workshop usually uses cam (Computer Aided Manufacturing) software to read CAD (CAD) files automatically and generate G code program to control the NC machine tool. The leading CNC machine brands are Hass, DMG (Deckel MAHO gildemester), Mazak, Mori Seiki, fadal and wasino.
2、 The route of computer gong processing:
The feed machining route of CNC lathe refers to the path that the tool moves from the point of alignment (or fixed origin of machine tool) until it returns to the point and ends the machining procedure, including the path of cutting and the path of cutting tool cutting and cutting out.
The feed route of finishing is basically carried out in the order of the outline of parts. Therefore, the key to determine the feed route is to determine the feed route of rough machining and empty stroke.
In the NC lathe processing, the determination of the processing route should follow the following principles.
① The accuracy and surface roughness of the workpiece to be processed shall be guaranteed.
② The shortest processing route, reducing the time of empty travel and improving the processing efficiency.
③ The work of numerical calculation and the processing procedure are simplified as much as possible.
④ For some reuse programs, subroutines should be used.
Besides the characteristics of ordinary milling machine, NC milling has the following characteristics:
- The parts processing is adaptable and flexible, and can process parts with complex outline or difficult to control size, such as mold parts and shell parts;
- It can process parts that can not be processed or difficult to process by common machine tools, such as complex curve parts described by mathematical model and 3D space surface parts;
- The parts that need to be processed by multiple processes after one clamping and positioning are processed;
- The high precision and reliable quality of the NC device are generally 0.001mm, and the high precision CNC system can reach 0.1 μ M. in addition, the operation error of the operators is avoided;
- The production automation is high, which can reduce the labor intensity of the operator. It is conducive to the automation of production management;
- The production efficiency is high, and the special process equipment such as special fixture is not required for CNC milling machine. When replacing workpieces, high-speed computer gong processing only needs to call the processing program, clamping tool and adjusting tool data stored in the NC device, thus greatly shortens the production cycle. Secondly, CNC milling machine has the functions of milling machine, boring machine and drilling machine, which makes the working procedure highly concentrated and greatly improves the production efficiency. In addition, the spindle speed and feed speed of CNC milling machine are stepless, so it is helpful to choose the best cutting amount.
2、 System classification of computer gongs processed by Shenzhen gongs:
① Cooling system. The cooling system of the machine tool is composed of cooling pump, water outlet pipe, return pipe, switch and nozzle. The cooling pump is installed in the inner cavity of the machine base. The cooling pump pumps the cutting fluid from the storage tank in the base to the outlet pipe, and then ejects through the nozzle to cool the cutting area.
② Lubrication system and method. Lubrication system is composed of manual oil donation pump, oil distributor, throttle valve, oil pipe, etc. The machine tool adopts periodic lubrication method, uses the manual lubrication oil pump, through the oil distributor to lubricate the spindle sleeve, the longitudinal and horizontal guide rail and the three-way ball screw, so as to improve the service life of the machine tool.
From the characteristics of digital control technology, because the servo motor is used in CNC machine tool, it should
