CNC CNC high-speed machining center common problems and solutions

Causes of high-speed machining center machining failure:

1. X Y Z axis backlash compensation is not correct

2. X, Y, Z main insert loosening

3. X Y Z bearing is damaged

4 Mechanical geometric precision deviation of the body

5. CNC machining center spindle axial and radial runout

6. Improper adjustment of system servo parameters and machining parameters

7. Errors in the customer's programming program

8. CNC machining center X Y Z axis silk rod, silk mother wear

CNC machining center solution countermeasures:

1. Micrometer calibration correct backlash

2. Adjust the main set of each axis loosening and tightening, the observation system load adjustment to ** state

3. Detection of bearing conditions, such as damage replacement

4. Marble angle ruler, ballbar detection of the geometric accuracy of the project, such as deviation correction

5. Repair the spindle bore accuracy, spindle bearing runout clearance, such as can not be repaired replacement

6. High-speed machining centers to adjust the servo position ring, speed ring gain, load inertia ratio, machining accuracy coefficient, acceleration and deceleration time constants.

7. Optimize and adjust the programming process

8. With the help of laser interferometer screw clearance compensation

V. High-speed machining center loose knife failure:

Reason:

1. Knife release solenoid valve damaged

2. Damage to the spindle knife cylinder

3. Damage to the spindle spring plate

4. Damage to the spindle puller

5. Insufficient air supply to the customer

6. Poor contact of knife release button

7. Broken wiring

8. Lack of oil in the oil cup of knife-beating cylinder

9. The customer's tool shank Latin does not meet the required specifications

Countermeasures:

1. Detect the operation of the solenoid valve, such as damage replacement

2. Detect the action of the knife cylinder, damaged replacement

3. Detect the degree of damage to the spring plate, replace the spring plate

4. Detect whether the spindle claw intact, damaged or worn replacement

5. Detect the degree of damage to the button, damaged replacement

6. Detect whether the line is broken

7. Fill the oil cup of the knife-beating cylinder with oil.

8. Installation in line with the standard Latin

Six, high-speed machining center machine can not return to zero point

Reason:

1. High-speed machining center home switch contacts are jammed can not be actuated

2. The home position block cannot press the home position switch to the switch action position.

3. The home switch into the water caused by the switch contact contact bad

4. The home switch line is disconnected or the input signal source is faulty.

5. PLC input point burned out

Countermeasures

1. High-speed machining centers to clean up the jammed parts, so that its movable parts of the smooth movement, or replacement of the travel switch

2. Adjust the installation position of the travel switch, so that the zero switch contact can be blocked by the smooth pressure to the switch action position.

3. Replace the travel switch and take waterproof measures.

4. Check the switch line for breaks and shorts, there is no signal source (+24V DC power supply).

5. Replace the input points on the I/O board of the high-speed machining center, set the parameters and modify the PLC program.
