Longkai Vertical machining centers
Structural performance of the machine:
1. Summary
The vertical machining center series machine tools adopt the imported control system (FANUC) from Japan and its matching servo driver and motor to realize three axis linkage. It is suitable for the parts with proper batch, which are complex, many processes, high precision requirements, need various types of ordinary machine tools, various cutting tools and tooling, and can be processed after many times of clamping and adjustment. Main processing box class, complex curved surface, special-shaped parts, disc, sleeve, plate parts. It is widely used in machinery, automobile, aircraft, aerospace, ship, national defense and other fields.
2. Machine structure
1) The main parts of the fuselage are made of high-quality cast iron, the internal ribs are strengthened, all of them are tempered, and the finite element analysis is carried out by the special design software. It has the characteristics of high strength, good stability and not easy to deform, which ensures the rigidity of the whole machine and the accuracy and stability of long-term use.
2) The transmission components are fag precision bearing and Rexroth high quality guide rail. The pre stretching process is adopted in the installation of ball screw, which can improve the rigidity of transmission parts and eliminate the elongation of ball screw caused by thermal stress effect during the operation of ball screw, and improve the accuracy maintenance of machine tool in long-term use.
3) Box type spindle head structure, reinforced internal tendons, and equipped with Taiwan famous brand Luoyi spindle, using P4 ultra precision angle ball bearing and large span support design, so that the spindle can bear strong radial and axial thrust, and eliminate vibration caused by heavy load cutting.
3. Technical features
1) Taiwan spindle, the highest speed up to 10000 rpm, with Japan's high-speed silent tooth belt drive, transmission does not slip and durable. The nose end of the spindle is designed to be dustproof with the air curtain of the spindle, which can prevent the entry of foreign matters and ensure the accuracy and service life of the spindle.
2) FANUC system of Japan has 10.4 inch color LCD display; the display part and control part are integrated structure, and fan free structure improves maintainability. Simple and easy-to-use operation screen; integrated design of control unit, equipped with the latest risc-cpu and high-speed graphics chip to achieve high-quality picture display; optical fiber servo communication drive connection; front-end CF card to realize the input and output of processing program and maintenance data, large capacity program direct editing; with programming auxiliary function; with various Wizard functions, G-code wizard, alarm wizard And operation wizard.
3) Support hard CF card, U disk, Ethernet and other program switching functions, greatly facilitating user program input and output. Advanced function of surface interpolation can realize high efficiency and high quality surface machining economically. Support online help, blueprint programming and background editing.
4) The servo drive and motor adopts FANUC motor from Japan, which has the characteristics of good control characteristics, large torque, good tracking accuracy and fast response.
5) The guide rail and ball screw adopt centralized automatic lubrication system, which can inject oil to each lubricating part regularly and quantitatively, ensure the uniform lubrication of each moving surface, effectively reduce the friction resistance, improve the motion accuracy, and ensure the service life of the guide rail and ball screw.
6) The machine tool adopts fully enclosed protection to ensure the personal safety of workers in the process of processing, and make the cooling liquid and iron filings in the process of processing be safely and fully recovered to ensure the cleanliness of the workplace. The guide rail of the machine tool is protected by the stainless steel telescopic cover of Taiwan Yinxing, which has the characteristics of good protection performance and long service life, which can effectively prevent iron chips and coolant from entering into the machine tool to damage the guide rail and screw. The electric control box adopts fully sealed design, and the heat exchanger is used for heat dissipation, which ensures the cleanness of the electric control box and the service life of the electrical components.
7) When the fuselage is assembled, the quality of each process is controlled according to the 50% tolerance of the national standard, which effectively reduces the whole machine deviation caused by the accumulated error. After the completion of the system assembly, 72 hours of copying machine operation, monitoring noise, vibration, rapid movement, tool change and other indicators. Advanced instrument testing machine tool is used to carry out parts trial processing detection, heavy cutting detection and rigid tapping detection, so as to ensure that all properties meet the factory's high quality requirements.
8) Project maturity and reliability
The company's vertical machining center series of machine tools have been mass production, widely used in various industries, after continuous improvement, the product is more convenient to use, more stable and reliable precision.
