As we all know, computer gongs processing is an automatic numerical control machinery, now many processing enterprises need this kind of mechanical equipment, but due to the fierce market competition, computer gongs processing chaos. The author suggests that before purchasing computer gong equipment, we must have a detailed understanding and investigation of the manufacturer.
Computer gong processing in the process of use will encounter some common faults, such as computer gongs can not return to zero, computer gongs positive and negative hard limit alarm, so what are the causes of these failures?
1、 Cause analysis of computer gong can not return to zero
1. The contact of the origin switch is stuck and cannot act; 2. The origin stop cannot hold the origin switch to the action position of the switch; 3. The water in the origin switch causes the contact of the switch to rust; 4. The line of the origin switch is disconnected or the input signal source is faulty; 5. The PLC input point is burnt out.
2、 Cause analysis of positive and negative hard limit alarm of computer gong
Computer gong processing under normal circumstances will not appear this alarm, but what is the cause of this situation?
1. The contact of the travel switch is pressed and stuck (over travel); 2. The travel switch is damaged; 3. The circuit of the travel switch is open circuit, short circuit and no signal source; 4. The limit block cannot hold the switch contact to the action position; 5. The PLC input point is burnt out.
Most of the time, due to the improper use of technical personnel, or work handover is not in place, computer gong processing will cause some problems, how should we prevent the deformation of parts in the process of computer gong processing?
Computer gong processing
In order to meet the requirements of ultra-high speed machining, the combination of spindle motor and machine tool spindle is adopted in computer gong machining, which realizes the integration of variable frequency motor and machine tool spindle. The bearing of spindle motor is in the form of magnetic levitation bearing, liquid dynamic and static pressure bearing or ceramic rolling bearing. Deformation often occurs in the process of processing, how to prevent it?
1、 In order to reduce the influence of cutting force and cutting heat, the deformation caused by rough machining can be corrected in finish machining.
2、 To reduce the influence of clamping force, the following measures should be taken to reduce the influence of clamping force:
1. When using radial clamping, the clamping force should not be concentrated on a certain radial section of the workpiece, and the operator should make it distributed over a large area to reduce the clamping force on the unit area of the workpiece.
2. The position of clamping force should be selected at the part with strong rigidity to improve the deformation of thin-walled parts under the action of clamping force.
3. The direction of clamping force is changed from radial clamping to axial clamping.
4. As we all know, computer gong is a kind of automatic numerical control machinery. Now many processing enterprises need this kind of mechanical equipment, but due to the fierce market competition, computer gong processing is chaotic. The author suggests that before purchasing computer gong equipment, we must have a detailed understanding and investigation of the manufacturer. In order to reduce the clamping deformation, special claws are used to clamp the workpiece, and the convex edge is cut off at the end of processing.
