1. The use and adjustment of headgearThe head frame of a CNC cylindrical grinder consists of a head frame box and a head frame base plate. The head frame box can rotate around the axis on the head frame base plate, and the angle of rotation can be read from the scale plate. The head rack dial can achieve segmented stepless speed regulation through a pulley and a frequency converter. The pre tension force of the triangular tape on one end of the headstock motor is adjusted by moving the headstock motor. The pre tightening force of the multi wedge belt on the headband dial is adjusted by rotating the eccentric sleeve. When rotating the eccentric sleeve, first loosen the set screw. After the eccentric sleeve is turned to the appropriate position, tighten the set screw.The gap between the headstock spindle and the bearing is adjusted by rotating the scale sleeve, which rotates clockwise to increase the gap; On ...

1. Check if the ground is level. If the level of the foundation bolts of the cylindrical grinder is not adjusted correctly, it will cause resonance of the equipment. Due to the poor flatness of the ground in production and processing sites, it is necessary to adjust the leveling screws to achieve a relative height for the equipment. First, check if every screw on the foot is securely fastened to the floor cushion. Use a level to check if the front, back, left, right, and up and down are aligned, and tighten the screws.2. After performing the above operation, if the vibration of the cylindrical grinder is not eliminated, the ground should be checked. If the ground is terrazzo or paved, it is relatively firm. If the cement floor is flat, the ground will be relatively empty, which will cause resonance. In this situation, you can buy a few gray black rubber pads from a plastic hardware store, with a thickness o...

Numerical control cylindrical grinder is a grinder that is pre programmed according to machining requirements, and numerical information instructions are issued by the control system for machining. It is mainly used for grinding cylindrical and conical outer surfaces. Generally, it has the characteristics of high universality, modularity, high precision, high rigidity, high efficiency, and good adaptability. According to different types of machine tools, it is suitable for batch processing of related parts in industries such as automobiles, motorcycles, air compressors, bearings, aviation, and aerospace.CNC cylindrical grinding machines occupy more height space and less land area, leaving space around the machine for active loaders or robotic arms, making automation a more attractive option. When conducting machine tool repair inspections, many repair personnel will find that some large cylindrical grinding...

NC external grinding machine

The CNC end face cylindrical grinder is suitable for grinding cylindrical and conical outer circles, especially for grinding cylindrical stepped shaft parts such as gear shafts, camshafts, crankshafts, etc. in gearboxes. By selecting appropriate grinding wheels and processes, the machining accuracy and roughness of the machine tool can stably meet the accuracy standards of the relevant machine tool. Now let's analyze how to deal with oil leakage faults? 1、 The oil leakage of the dust-proof sheet metal at both ends of the workbench is usually caused by careless assembly of the machine tool. The screws that fix the dust-proof sheet metal have penetrated through both ends of the guide rail, and oil directly seeps out from the guide rail. The solution is to wrap the machine tool screws with adhesive tape, apply sealant, and then put them on. 2、 The oil level adjustment is too large. After opening the...

How to solve the vibration problem of CNC internal grinding machine

An external cylindrical grinder generally consists of a cast iron bed body, a worktable, a headstock and tailstock that support and drive the workpiece to rotate, a grinding wheel rack (grinding head) that installs the grinding wheel, a transverse feed mechanism that controls the size of the grinding workpiece, and electrical and hydraulic devices that control the movement of the machine tool's moving parts. Maintenance work can be divided into early and late stages.1、 Early stage(1) Clean the iron chip groove, water tank, oil filter, disk, hydraulic pump, pipeline, oil circuit, and accessories of the cooling pump, and clean and adjust the grinding head of the external cylindrical grinder.(2) Check the pressure of the pressure valve, whether the hydraulic handle and guide rail can operate flexibly, and whether the stroke speed is normal.(3) Check if the screws are tightened, clean all parts of the ma...

How to make grinding tools energy-efficient and environmentally friendly

The process of CNC cylindrical grinding machine is influenced by many factors, resulting in corresponding errors. These factors can be classified into two types: one occurs during the metal cutting process, and the other is the process structure and state itself. It can be specifically divided into the following categories:(1) Error caused by spindle rotationThis type of error is mainly caused by axial displacement, angular swing, and other factors, including various errors in the bearings themselves and axial errors between bearings.(2) Guide rail errorThe guide rail of a machine tool is the standard for the relative position of its components, and it is also the benchmark for the operation of a CNC cylindrical grinder. The errors generated by the guide rail will be directly reflected on the processed workpiece, which will have a corresponding impact on the machining accuracy of the workpiece. When the too...

CNC end face cylindrical grinder is a grinder used to machine the outer surface and shoulder end face of cylindrical, conical, or other shaped elements of workpieces; Widely used, capable of processing various cylindrical conical outer surfaces and shaft shoulder end face grinders.The factors affecting the accuracy of the equipment are as follows:1. The influence of the height of the grinding head, headstock, and tailstock on the dimensional accuracy of the workpiece.The height error of the grinding head, headstock, and tailstock will cause the centerline of the headstock and tailstock to deviate from the axis of the grinding wheel spindle in space, resulting in a hyperbolic surface on the surface of the workpiece being ground.2. The influence of the parallelism error of the grinding head spindle axis in the horizontal plane on the dimensional accuracy of the workpiece caused by the centerline connecting th...
