What are the basic principles for positioning and installation in CNC machining? The basic principle of position installation when machining parts on CNC machine tools is to choose a reasonable positioning standard and fixing scheme. What should be noted when making a selection? Let's take a brief look together.

1. Strive to standardize design, process, and programming calculations.

2. Minimize the number of clamping times, place the clamping device in one go, and then process all surfaces to be processed.

3. Avoid using manual machine adjustment machining schemes and fully utilize the performance of CNC machines.

What are the safety operation regulations for CNC machining? Let's take a brief look together.

In order to use digital control machines correctly and reasonably, reduce the occurrence rate of faults, and use operating methods. Only with the consent of the machine tool administrator can the machine tool be operated.

(1) Precautions before starting up:

1) The staff must be familiar with the performance and working methods of this digital control machine. Only with the consent of the machine tool administrator can the machine tool be operated.

2) Before turning on the machine power, confirm whether the voltage, air pressure, and hydraulic pressure meet the working requirements.

3) Check if the moving parts of the machine tool are working properly.

4) Check if there is any offside on the workbench.

5) Check if the electrical components are secure and if the wiring is loose.

6) Ensure a stable connection between the machine grounding wire and the workshop grounding wire (especially important during initial start-up).

7) The main power switch can only be turned off after being ready before starting up.

(2) Guidance process precautions:

1) Strictly follow the start-up sequence in the machine tool manual.

2) Generally speaking, during the guidance process, the first step is to return to the machine tool reference point, making the machine tool a coordinate system.

3) After starting up, let the machine idle for more than 15 minutes to maintain balance.

4) After shutting down, it is necessary to wait for more than 5 minutes before turning on again. Unless there are special circumstances, it is not advisable to frequently turn on or off.

(3) Debugging process precautions:

1) Edit, modify, and debug programs. If the first trial cut must be run publicly, it is necessary to confirm whether the program is correct.

2) Install and debug fixtures according to process requirements, remove iron and debris from each positioning surface.

3) Assemble the workpiece according to the positioning requirements to ensure accurate and reliable positioning. During the processing, there should be no looseness of the workpiece.

4) Install the tools to be used. For machining centers, the tool reference number in the tool library must match exactly with the tool number in the program.

5) Set the workpiece coordinate system based on the programming origin of the workpiece. If multiple tools are used, the rest will be compensated for length or tool tip position separately.

CNC machining is an advanced machining equipment with high degree of automation and complex structure. In order to fully leverage the advantages of machine tools and improve production efficiency, it is particularly important to manage, use, and maintain CNC machine tools. The quality of technical personnel and civilized production are particularly important. In addition to being familiar with the performance of CNC machine tools and proficient in operation, operators must also cultivate good work habits and rigorous work styles in civilized production, and must have good professional qualities, a sense of responsibility, and a spirit of cooperation. In the operation, you must:

(1) Strictly follow the safety operation procedures of CNC machine tools. Without professional training, one cannot operate the machine tool without authorization.

(2) Strictly adhere to the commuting shift system.

(3) Use the machine well, manage it well, and have a strong sense of responsibility.

(4) Maintain a clean environment around CNC machine tools.

(5) Operators must wear work clothes and shoes, and are not allowed to wear dangerous clothing.
