Introduction to common measuring instruments required for several CNC cylindrical grinders

2025-04-07

Introduction to common measuring instruments required for several CNC cylindrical grinders.1、 Active outer diameter measuring instrument:Active measurement refers to continuously measuring the dimensional changes of the workpiece during the grinding process, and transmitting the dimensional changes to the control instrument, which then sends signals to control the action of the machine tool. Due to its ability to measure workpieces without stopping the machine, it reduces labor intensity, increases production efficiency, reduces scrap rates, and produces workpieces with high dimensional consistency, making it suitable for use in large-scale assembly line operations such as automotive parts and bearing parts processing.2、 End face locator:Installed on the grinding wheel rack, the end face measuring instrument is extended and retracted by the cylinder, and the measuring position of the measuring...

A brief introduction to the production of the tailstock for external cylindrical grinding machines

2025-04-07

Briefly introduce the production of the tailstock for external cylindrical grinding machines.The workpiece spindle device and tailstock of the external cylindrical grinder are installed on both ends of the worktable. The tailstock is matched with the worktable through a sliding groove tenon structure. One end of the workpiece with a longer axial length is clamped by the workpiece spindle device, and the other end is supported by pushing the tailstock to drive the pointed shaft on the tailstock. Then, manual control is used to generate a pressing force on the workpiece. The workpiece spindle device drives the workpiece to rotate, and the grinding wheel device performs external surface machining on the workpiece.During the process of pushing the tailstock to the top, if the pointed axis on the tailstock moves quickly, it is easy to generate a large impact force on the workpiece, affecting the machining accura...

Is the clear specification for discussing the drilling volume of CNC cylindrical grinders clear

2025-04-11

Is the clear specification for discussing the drilling volume of CNC cylindrical grinders clear?Reasonably clarifying the drilling volume of CNC cylindrical grinders is of great practical significance for increasing labor productivity and ensuring production and manufacturing quality. Generally speaking, drilling is a precision machining production process. Compared with other milling methods, its milling efficiency is much higher and lower. Excessive surplus will reduce cost and efficiency, and increase the power installation project consumption of sand wheels and machining centers.In some cases, the quality of the parts may continue to decrease again, such as for cast iron parts that have undergone surface high-frequency quenching and high-frequency heat treatment. Their surface compressive strength is high, but the compressive strength decreases as they move inward. If the volume is large before polishin...
