Numerical Control Milling Machine

General Introduction of Machine Tool

The numerical control milling machine can be equipped with a control system imported from Japan and its supporting servo drive and motor to realize three-axis linkage. It is suitable for parts with appropriate batches that are complex, have many processes, require high precision, require various types of ordinary machine tools and a large number of tools and tooling, and can only be processed after multiple clamping and adjustments. Mainly process boxes, complex curved surfaces, special-shaped parts, discs, sleeves, and plate parts. Widely used in products in the fields of electronics, machinery, automobiles, aircraft, aerospace, ships, and national defense.

two. The main structure and technical characteristics of the machine tool

1. Bed
The main parts of the fuselage are made of high-quality cast iron, and the internal ribs and bones are strengthened. All of them have been tempered, and the finite element analysis has been carried out by special design software. The precision stability used.

2. Spindle
The box-shaped spindle head structure, the internal ribs and bones are strengthened, and the P4-level ultra-precision bevel ball bearing and large-span support design are used to enable the spindle to withstand strong radial and axial thrusts and eliminate vibrations generated under heavy-duty cutting. Equipped with Taiwan's famous brand spindle and Japanese high-speed silent toothed belt drive, the drive is non-slip and durable. The nose of the spindle is designed to cooperate with the air curtain of the spindle to prevent dust, which can prevent the entry of sundries and ensure the precision and life of the spindle. The imported oil cooler cools down the temperature of the main shaft, improves the service life of the bearing, and reduces the influence of the thermal deformation of the main shaft on the machining accuracy.

3. Transmission parts
Imported precision bearings and high-quality precision ball screws from Taiwan are used. The installation of the ball screw adopts the pre-stretching process, which improves the rigidity of the transmission parts and eliminates the elongation of the ball screw due to the thermal stress effect when the temperature rises during operation, which improves the accuracy of the long-term use of the machine tool. sex.

4. Guide rail
X, Y (four guide rails) axes adopt high-precision, high-speed, high-load-bearing ball linear slides and ball screws to ensure dynamic accuracy and durable service life. The Z-axis adopts the design of hardened sliding track, which is matched with the veneer of the PTFE guide rail. It has the characteristics of high rigidity, high wear resistance, etc., and has extremely high processing stability. The Z-axis is balanced with a counterweight to reduce the load on the Z-axis motor;

5. System
Equipped with a high-performance numerical control system, it can adapt to high-efficiency, high-speed, and high-precision machining; and has the advantages of convenient operation, complete functions, and high reliability. The electrical design of the machine tool complies with the GB5226.1-2000 electrical standard. The power circuit of the circuit has over-current and short-circuit protection, and the relevant actions of the machine tool have corresponding interlocks to ensure equipment and personal safety. The electrical system has a self-diagnosis function. Operators and maintenance personnel can observe the running status of each part of the machine tool at any time according to the indicator lights and displays. The main electrical components are imported products, and other electrical parts are selected from Sino-foreign cooperative products, so as to ensure the safety and reliability of the machine tool. CNC machine tools have strict requirements on power supply. If the fluctuation of the user's power grid exceeds ±10%, and the frequency exceeds 50Hz±0.5Hz, a voltage stabilizing device must be added, otherwise the CNC machine tool will not work correctly, and even unpredictable results will appear.

6. Drive
The motors and drives configured by the three coordinate axes of X, Y, and Z have the characteristics of good control characteristics, large torque, good following accuracy, fast response, and good stability.

7. Lubrication
Guide rails and ball screws adopt a centralized automatic lubrication system, which can regularly and quantitatively inject oil to each lubrication part to ensure uniform lubrication of each moving surface, effectively reduce frictional resistance, improve motion accuracy, and ensure the service life of guide rails and ball screws.

8. Machine tool protection
The machine tool adopts fully enclosed protection to ensure the personal safety of the staff during the processing, and the coolant and iron filings during the processing can be safely and fully recovered to ensure a clean and tidy workplace. The guide rail of the machine tool is protected by a Taiwan telescopic cover, which has the characteristics of good protection performance and long service life, and effectively prevents iron filings and coolant from entering the machine tool and damaging the guide rail and screw. The electric control box adopts a fully sealed design, and a heat exchanger is selected for heat dissipation, which ensures the cleanliness of the electric control box and the service life of electrical components.

9. Quality Assurance
During the assembly of the fuselage, each process carries out quality control according to the national standard tolerance, which effectively reduces the deviation of the whole machine caused by accumulated errors. After the system assembly is completed, 72-hour copy machine operation is carried out to monitor various indicators such as noise, vibration, rapid movement, and tool change. Adopt advanced instruments such as laser interferometer, ballbar, dynamic balancer and three-coordinate measuring instrument to test machine tools, carry out part trial processing inspection, heavy cutting inspection, rigid tapping inspection, and ensure that various performances meet the factory's high-quality standards.

The safety design of the machine tool conforms to the relevant provisions of GB15760-2004 "General Technical Conditions for Safety Protection of Metal Cutting Machine Tools", and its geometric accuracy standard conforms to GBT_18400.2-2010 "Machining Center Inspection Conditions Part 2: Vertical or Universal with Vertical Main Rotary Axis Spindle Head Machine Tool Geometric Accuracy Inspection (Vertical Z-axis)" and GBT 18400.4 "Machining Center Inspection Conditions Part 4: Linear and Rotary Axis Positioning Accuracy and Repeated Positioning Accuracy Inspection" relevant regulations.
