What is CNC machine tool?

CNC machine tool is the computer numerical controlled (CNC) machine which can provide powerful, fast and precision workpiece cuts with indexable tools or drills.  one of the most widely used CNC lathe machines. The CNC lathe tool is mainly used for the inner and outer cylindrical surfaces of shaft parts or disc parts, the inner and outer conical surfaces of any taper angle, the complex inner and outer curved surfaces, the cylindrical and conical threads, etc., CNC machine tool can also be used for grooving, drilling, reaming and reaming. Holes and borings, etc.

The CNC machine tool automatically processes the machined parts according to the pre-programmed machining program. We process the machining process route, process parameters, tool trajectory, displacement, cutting parameters and auxiliary functions of the parts according to the instruction code and program format specified by the CNC machine tool, and then record the contents of the program list. On the control medium, hot sale CNC lathe is then inputted into the numerical control device of the CNC machine to direct the machine to machine the parts.

What are the characteristics of CNC machine tool?

CNC machine tool is the abbreviation of the digital control machine tool, which is an automatic machine tool with the program control system. The control system can logically process and decode the program with control code or other symbolic instructions to cause the machine to operate and machine the part.

Compared with ordinary machine tools, CNC machine tools have the following characteristics:

• High processing precision and stable processing quality;
• The multi-coordinate linkage can be performed to process parts with complex shapes;
• When the machined parts are changed, generally only need to change the NC program, which can save production preparation time;
• The machine tool itself has high precision and rigidity and can choose favorable processing amount, and the productivity is high (usually 3~5 times of ordinary machine tools);
• The degree of automation of the machine tool is high, which can reduce the labor intensity;
• The quality of the operators is high, and the technical requirements for maintenance personnel are higher.

The normal use of the CNC lathe must meet the following conditions: the power supply voltage fluctuation at the position where the machine is located is small, the ambient temperature is lower than 30 degrees, and the relative temperature is less than 80%.

Environmental requirements for CNC machine tool

The position of the machine tool should be away from the vibration source, and the direct sunlight and heat radiation should be avoided to avoid the influence of moisture and air flow. If there is a vibration source near the machine tool, anti-vibration grooves should be installed around the machine. Otherwise, it will directly affect the machining accuracy and stability of the machine tool, which will make the electronic components contact poorly, cause malfunction, and affect the reliability of the machine tool.

Power requirements for CNC machine tool

Generally, the CNC lathe is installed in the machine shop, which not only has large changes in ambient temperature, but also has poor operating conditions, and many kinds of electromechanical equipment, resulting in large fluctuations in the power grid. Therefore, the location of the CNC lathe requires strict control of the power supply voltage. Power supply voltage fluctuations must be within the allowable range and remain relatively stable. Otherwise, it will affect the normal operation of the CNC system.

Temperature conditions of CNC machine tool

The ambient temperature of the CNC lathe is less than 30 degrees, and the relative temperature is less than 80%. Generally speaking, the numerical control electric control box is internally provided with an exhaust fan or a cooling fan to keep the electronic components, especially the central processing unit, with a constant operating temperature or a small change in temperature difference. Excessive temperature and humidity will result in reduced life of the control system components and lead to increased failure. Increased temperature and humidity, increased dust can cause bonding on the integrated circuit board and cause short circuits.

Standardized use of CNC machine tool

When using the machine, the user is not allowed to arbitrarily change the parameters set by the manufacturer in the control system. The setting of these parameters is directly related to the dynamic characteristics of the various parts of the machine. Only the value of the gap compensation parameter can be adjusted according to the actual situation.

The user cannot change the machine attachment at will, such as using a hydraulic chuck that exceeds the specifications. When setting up the accessories, the manufacturer fully considers the matching of the parameters of each link. Blind replacement causes mismatches in the parameters of various links and even causes an accident that is not estimated.

The pressure of the hydraulic chuck, hydraulic tool holder, hydraulic tailstock, and hydraulic cylinder should be within the allowable stress range, and no increase is allowed.

Maintenance of CNC machine tool

CNC turning lathe is a high-precision, high-efficiency automated machine tool. Equipped with multi-station turret or power turret, the machine tool has a wide range of processing performance, can process linear cylinders, diagonal cylinders, arcs and various complex workpieces such as threads, slots, worms, with linear interpolation, arc Interpolated various compensation functions and played a good economic effect in the mass production of complex parts. The maintenance of the inclined bed CNC lathe is as follows:

In order to ensure the working accuracy of the inclined bed CNC lathe and prolong the service life, it is necessary to carry out reasonable maintenance work on the self-use slant bed CNC lathe. The quality of lathe maintenance directly affects the processing quality and production efficiency of the workpiece. When the Taiwanese Taichung Seiki CNC lathe runs for 500h, it needs to be level 1 maintained. The maintenance work of the inclined bed CNC lathe is mainly carried out by the operator and the maintenance worker cooperates. When servicing, the electric probe must be cut off first, and then maintained according to the maintenance contents and requirements.
