2023-05-17 Factors Affecting Machine Rigidity The term 'rigidity' used by people in the machine tool industry refers to the measurement of the amount of deformation caused by a machine tool under force. The rigidity of CNC Lathe is reflected in two aspects: static rigidity and dynamic rigidity. The static rigidity of the machine tool indicates the size of the deformation of the machine tool itself caused by the machine tool during the cutting process. In addition, there are deformation of the guide rail, deformation of the bed and so on. The static rigidity is composed of many factors, the most important being the static rigidity of the three-axis screw system. Dynamic rigidity is the most important index to measure the rigidity of a machine tool. Generally speaking, the dynamic rigidity of a machine tool refers to the ability of the machine tool to resist forced vibration. The CNC machine tool rotates at high speed during cutting, and the vibration of the machine tool is caused by the rotating cutting and the unevenness or impurities inside the material. The cutting part is the vibration source of the whole equipment. The screw system, guide rail system and bed of the equipment will produce forced vibration under the influence of the vibration source. If the vibration of each part of the machine tool is large, it will have a very adverse effect on the processing, mainly affecting the roughness of the cutting and the life of the tool, and it will have a fatal effect on high-precision processing. How to ensure the high rigidity of a machine tool? First of all, the reasonable structure of the bed incr

2023-05-09 Why did the accuracy of CNC Lathe suddenly decrease? First, causes of abnormal machining accuracy faults Five main reasons: 1. The feed unit of the machine tool is changed or changed; 2. The zero offset of each axis of the machine tool is abnormal; 3. The axial backlash is abnormal; 4. The motor running state is abnormal, that is, the electrical and control parts are abnormal ; 5. Mechanical failure, such as screw, bearing, shaft coupling and other components. In addition, the preparation of machining programs, the selection of cutting tools and human factors may also lead to abnormal machining accuracy.

2023-05-06 Workpiece Clamping Skills of CNC Machine Tool After the workpiece is positioned, a clamping force is generated through a certain structure, and the workpiece is pressed against the positioning element to maintain an accurate positioning position, and the position will not be generated due to the cutting force, workpiece gravity, centrifugal force or inertial force of the CNC lathe, etc. Changes and vibrations to ensure machining accuracy and safe operation. This mechanism for generating clamping force is called clamping device. 1.The basic requirements that the clamping device should have (1) The clamping process is reliable and does not change the correct position occupied by the workpiece after positioning. (2) The clamping force is appropriate. It is necessary to ensure that the position of the workpiece is stable and the vibration is small during the processing, and it is also necessary to prevent the workpiece from excessive clamping deformation. 2.Selection of clamping force direction and action point (1) The clamping force should be directed towards the main positioning datum. (2) The action point of the clamping force should fall within the support range of the positioning element and be close to the geometric center of the support element. The clamping force acts outside the support surface, causing the workpiec

2023-04-27 The Adjustment of the Gap Between the Spindle and Bearing of CNC Machine Tool CNC machine tools are high-precision, high-efficiency, and highly automated machine tools, in which the spindle is an important part of the CNC machine tool. As the core component of CNC machine tools, the spindle is responsible for the tasks of rotating workpieces and cutting. 1. The effect of adjusting the gap between the spindle and the bearing of the CNC machine tool Too large or too small radial and axial clearances of the spindle bearings of CNC machine tools are the main reasons for the failure of CNC machine tools. If the gap is too large, the spindle will jump, and the turned workpiece will produce ellipses, round edges or ripples; if the gap is too small, the spindle will heat up and be damaged at high speed. When adjusting, first loosen the locking screw 5 and the nut 4, so that the inner ring of the bearing 7 moves to the right relative to the tapered journal of the main shaft. Due to the action of the tapered surface, the inner ring of the bearing produces radial elastic expansion, which reduces the gap between the roller and the inner and outer rings. After the CNC machine tool is properly adjusted, the locking screw 5 and nut 4 should be tightened. The clearance of bearing 3 can be adjusted with nut l. Under normal circumstances, it is only necessary to adjust the front bearing. Only when the required rotation accuracy cannot be achieved after adjusting the front bearing, the rear bearing can be adjusted. The rear bearing can adjust the axial clearance and precision of the main shaft. 2. Operation steps of adjusting front bearing of CNC machine tool

2023-04-20 Clamping Method and Alignment Measures for Turret Lathe There are two clamping methods for turret lathes, one is the inline type and the other is the VDI type. An inline turret is a tool that is directly installed on the tool holder. Due to the lack of intermediate adapters in the inline turret, the rigidity of the tool after clamping is good, but changing the tool takes time. When selecting a tool, the form and size of the tool should be determined based on the width of the turret groove. When installing drilling and drilling tools, an adapter is required. The tool holder is made of self boring holes and is not interchangeable. During installation, attention should be paid to matching the machine tool with the tool number. The dimensions of the boring cutter and drill bit should refer to the form and size of the adapter seat, and transition sleeves can be added if necessary. VDI turrets cannot be directly installed and require various forms of VDI adapters. Due to the installation of these tool holders on the surface of the turret, the cantilever beam is longer and not as rigid as the inline type. The interface between VDI turret and tool holder is mainly determined by the tool aperture on the end face of the turret. If the tool aperture is 40mm, the VDI tool holder should choose the VDI40 interface. In addition, when selecting the tool holder, it should be noted that the VDI tool holder is divided into left and right tool holders, front and back tool holders, etc. This depends on the orientation of the machine tool turret and processing technology. Adjustment measures for clamping of turret lathe: 1. Clamp the workpiece onto a four jaw single action chuck. To increase the degree of freedom of

2023-03-30 How to deal with the common faults of CNC Lathe tool post When the CNC Lathe is used, the automatic rotary tool holder often fails, and many people do not know how to solve it. Fault 1: The tool holder of the CNC Lathe is shifted, but the tool holder has turned to multiple tool positions and cannot be fixed on any tool position. Cause Analysis: The Hall element for detecting the position of the tool post is faulty. The CPU board or position signal board of the control system is faulty. Elimination measures: Detect the static and dynamic parameters of the Hall element, such as abnormal parameters, replace parts. Replace the CPU board and locate the multiplier board. Fault 2: The CNC Lathe tool holder is indexed, but the lock is not tight or in place, and the tool holder will shake left and right when pulled by hand. Cause analysis: The reverse circuit of the tool holder motor is faulty, and the motor does not reverse, because when the tool rotates, the motor should reverse immediately, put down the tool holder body, and position and lock it in the positioning groove of the tool holder base. If the motor does not reverse, the above actions cannot be completed, and the knife holder will become loose. When the

After understanding the customer's taboos, arrange the restaurant to have meals with the customer.

2023-03-08 Tool changing manipulator failure What is the reason for the failure of the tool changing manipulator? How to solve it? There are generally three types of manipulator failures: 1. The tool clamp is not tight. It may be that the spring pressure of the clamping claw is too small or the nut behind the spring is loose, or the tool is overweight, and the clamping lock does not work, etc. 2. The tool cannot be loosened after being clamped. The reason may be that the spring of the loose lock is pressed too tightly, and the claws cannot be retracted. The nut should be loosened so that the maximum load does not exceed the rated value. 3. The tool is dropped when the tool is changed, or the spindle box does not return to the tool change point or the tool change point drifts when the tool is changed. It may be because the manipulator started to pull the knife when it was not in place when grabbing the knife, which would cause the knife to drop. At this point, the headstock should be moved again to return to the tool change point to reset the tool change point.
