These Problems aAre Prone To Occur In CNC Machining

Apr 25 , 2023 | Blog

CNC processing workpiece is cut:


  1. Barger knife, the knife is not too long or too small, causing the knife to play the knife.

  2. Improper operation of operators.

  3. Unexplained the cutting waste. (For example: 0.5 on the surface of the surface, 0.15 on the bottom surface)

  4. Improper cutting parameters (such as: too large tolerance, SF settings too fast, etc.).



  1. Use the knife principle: can be big or small, short or long.

  2. Add an angle clearing program, and the balance is as uniform as possible, (the side and the amount of the bottom surface are consistent).

  3. Reasonably adjust the cutting parameters, and the remaining corner is repaired.

  4. Use the SF function of the machine tool, the operator is fine -tuned to make the machine cut into the best effect. two,


CNC processing points:


  1. The operator is inaccurate when manually operating.

  2. There are burrs around the mold.

  3. Magnetic is magnetic.

  4. The four sides of the mold are not vertical.



  1. Careful inspection should be performed manually, and the same height should be at the same point as possible.

  2. Use oil stones or swords around the mold to remove the burrs clean with a broken cloth, and finally confirm it with your hand.

  3. Before the mold is divided, the division rod will be resolved first, (the ceramic can be divided into a might or other).

  4. Is the school watch inspection of the four sides of the mold vertical and (the vertical error requires a large review plan with the fitter).


Third, the problem with the knife:


  1. The operator is inaccurate when manually operating.

  2. There is an error in the knife.

  3. The blade on the flying knife is error (the flying knife itself has a certain error).

  4. There is an error between the R knife and the flat knife and the flying knife.



  1. Careful inspection should be performed manually, and the knife should be the same as possible.

  2. Wipe clean with a wind gun or wipe it with a blast gun.

  3. You can use a blade when you measure the knife pole and the bottom of the light.

  4. A separate pairing of the knife program can avoid errors between the R flat knife and the knife.


Fourth, collision-programming:


  1. Insufficient safety heights or no set (when you quickly enter the G00, the knife or pinch is hit on the workpiece).

  2. The knife and actual program knife on the program list are wrong.

  3. The length of the tool on the program (the blade length) and the in -depth writing of actual processing are wrong.

  4. The depth of the Z axis on the program and the actual z -axis number is wrong.

  5. The seat setting is wrong when programming.



  1. Accurate measurement of the height of the workpiece also ensures that the safety height is above the workpiece.

  2. The tools on the program form and the actual program tool should be consistent (as try to use the program single or the program out of the program).

  3. Measure the depth of the actual processing on the workpiece, and write the length of the tools and the length of the blade on the program form (the general tool clip is 2-3mm high, and the blade is 0.5-1.0mm).
