Fault diagnosis method for CNC cylindrical grinder

2025-04-10

The fault diagnosis of CNC cylindrical grinder can be based on the following methods or criteria:1. Intuitive method: It mainly relies on some abnormalities to make judgments, such as abnormal noises, sparks, odors, abnormal heating, etc., and then further judgments are made. This is a relatively simple method, but it requires maintenance personnel to have corresponding maintenance experience.2. Utilize the hardware alarm function of the CNC system: that is, use the alarm indicator light to roughly determine the location of the fault.3. Utilizing the alarm function of CNC system software: Generally speaking, CNC systems have automatic diagnostic functions to diagnose the system. Once a fault is detected, it will be displayed through a display screen or alarm light. Therefore, we can use it to determine the location of the fault.4. Using the detection terminals on the circuit board: Because there are detecti...

Application of grinding wheel in mold grinding

2025-04-10

The difference between tool grinding and other types of grinding is that both rely on manual grinding machines for processing, so the skill level of the operator plays a crucial role. Among them, the selection of grinding wheel particle size, the degree of grinding wheel dressing judgment, and the control of manual feed rate are all judged based on experience. Tool grinding is generally divided into three categories: rough grinding, fine grinding, and corner cleaning. 1. Rough grinding: Typically, 46 # grit grinding wheels are used to grind the cut workpiece to the required size, achieving the desired flatness and smoothness. 2. Precision grinding: Usually, 100 # or 120 # grinding wheels are used. In addition to precision grinding the flat surface, sometimes grooves need to be ground, and there are also high requirements for the shape retention of the grinding wheel. 3. Corner cleaning: Trim the ...

Position adjustment and grinding work of CNC cylindrical grinder

1. Application and adjustment of bed frameThe bed is a box shaped casting. The front part of the bed is used as an oil tank. The electrical equipment is placed on the rear right part of the bed, and the oil pump equipment is installed on the wall at the rear of the bed.2. Application and adjustment of workbenchThe workbench is mainly composed of an upper table and a lower table. Loosen the hexagonal screws on the two pressure plates of the upper table, roll the adjustment handle, and the upper table can be reversed within a regular range to adjust the taper of the workpiece. After turning the upper table to the desired viewpoint, tighten the hexagonal screws of the two pressure plates before grinding. The label on the right pressure plate has two types of markings, one indicating taper and the other indicating share. When the tabletop rolls more than 6 degrees, the grinding wheel holder must rotate to a cer...

Precautions for installation of CNC tool grinder

2025-04-09

A surface grinder is a commonly used machine tool for mechanical processing. There are high requirements for motion stability, commutation accuracy, and commutation frequency. The motion inertia of large high-speed surface grinders is very large. When they change direction, it will cause a sharp increase in back pressure, resulting in a reversal impact, which will have a catastrophic impact on the machine tool. Therefore, the problem of smooth reversal has become an important factor restricting the improvement of grinding machine working speed and machining accuracy. There are many hydraulic transmission reversing methods currently applied to surface grinders. Based on the analysis of commonly used hydraulic transmission reversing methods, a simple comparison and analysis will be made below. The method of reversing using a stroke reversing valveA pull rod is connected to the reversing valve core to use a ...
