what can you make with cnc machine

1. Familiarity with CNC machine tools

CNC machine tool is the abbreviation of numerical control machine tool, which is an automatic machine tool equipped with a program control system. The control system can logically process and decode programs with control codes or other symbolic instructions, so as to make the machine tool move and process parts. The CNC lathe is a milling machine with a wide range of applications. It can grind and polish planes, grooves, toothed parts and various curved surfaces on the CNC lathe. In addition, it can also be used to process the surface of the rotating body, bore holes and carry out disconnection work, etc. When the CNC lathe is in operation, the casting is installed on the workbench or on the accessories such as the indexing plate. The turning tool rotates as the leading movement, supplemented by the operation table or the boring tool movement, and the casting can obtain the required polished surface. In view of the multi-tool uninterrupted drilling, the production efficiency of CNC lathes is relatively high. A milling machine that cuts, grinds and polishes castings with a boring tool. In addition to cutting planes, grooves, gear teeth, threads and spline shafts, CNC lathes can also grind and polish surfaces with complex structures. The speed is higher than that of drilling machines, and it is widely used in mechanical equipment manufacturing and maintenance institutions.

2. Composition of CNC machine tools

(1) The main engine, which is the subject of the CNC machine tool, includes mechanical components such as the machine body, column, spindle, and feed mechanism. It is a mechanical component used to complete various cutting processes.

(2) Numerical control device is the core of CNC machine tools, including hardware (printed circuit board, CRT display, key box, tape reader, etc.) and corresponding software, used to input digital part programs and complete the storage of input information , Data transformation, interpolation operation and realization of various control functions.

(3) The driving device is the driving part of the CNC machine tool actuator, including the spindle drive unit, feed unit, spindle motor and feed motor. It realizes the spindle and feed drive through the electric or electro-hydraulic servo system under the control of the numerical control device. When several feeds are linked, the processing of positioning, straight lines, plane curves and space curves can be completed.

(4) Auxiliary devices, some necessary supporting parts of the index control machine tool, are used to ensure the operation of the CNC machine tool, such as cooling, chip removal, lubrication, lighting, monitoring, etc. It includes hydraulic and pneumatic devices, chip removal devices, exchange tables, CNC turntables and CNC dividing heads, as well as tools and monitoring and testing devices.

(5) Programming and other auxiliary equipment can be used to program and store parts outside the machine.


3. Features of CNC machine tools

(1) High processing precision and stable processing quality;

(2) Multi-coordinate linkage is possible, and parts with complex shapes can be processed;

(3) When the processing parts are changed, generally only the NC program needs to be changed, which can save production preparation time;

(4) The machine tool itself has high precision and high rigidity, can choose a favorable processing amount, and has high productivity (generally 3 to 5 times that of ordinary machine tools);

(5) The machine tool has a high degree of automation, which can reduce labor intensity;

(6) The quality requirements for operators are higher, and the technical requirements for maintenance personnel are higher.


4. The use of CNC machine tools

CNC lathes are suitable for cutting planes, slopes, grooves, etc. If you use all-round milling head, round operating table, indexing plate and other drilling machine accessories, you can also increase the grinding and polishing range of the CNC lathe. The CNC lathe has any rigidity and power, has powerful processing capabilities, and can complete high-speed and heavy-duty drilling and gear processing. It is suitable for grinding and polishing of abrasive special steel, mining machinery equipment, manufacturing equipment and other heavy-duty and medium-sized precision processing. The operating table of the vertical milling machine can be rotated 45° to the left and right. When the operating table is rotated to a certain inclination and the indexing plate attachment is selected, various helical surfaces can also be polished. The three-way feed screw of the boring machine is a trapezoidal screw or a ball screw.

(1) Cutting material

First of all, the CNC machine tool has the advantage of multi-axis, so it can realize the cutting of some parts during the part manufacturing process, not only can cut metal and plastic with regular shape, but also can realize different models, Precision machining of parts of any size and shape.

(2) Create a prototype

In addition to being able to program the tool path to realize the cutting of the parts, the CNC machine tool can also directly create and form the prototype of the parts. The principle is to control the movement and processing of the machine tool through the calculation and setting of the system programming. Intelligent system programming can better meet different parts processing and manufacturing needs, and fully automatic processing can be realized only through preset programming and command sequences.

(3) Intelligent and convenient

Compared with traditional machine tools, the biggest advantage of CNC machine tools is that it can liberate the labor force and solve the shortcomings and limitations of manual control. It is no longer that the operator operates through levers or handwheels, but through precise calculations by computers. For the processing of parts It is more accurate, and it can also improve work efficiency, and it is more intelligent and convenient to use.
