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...

Understand the process and precautions of starting the grinding wheel of the cylindrical grinder every time

2025-04-11

Understand the process and precautions for starting the grinding wheel of the cylindrical grinder each time.1. Before starting the grinding wheel each time, the hydraulic on-off valve should be placed in the stop position, the adjustment handle should be placed in the low-speed position, and the grinding wheel seat feed handle should be placed in the reverse position to avoid accidents.2. Before starting the grinding wheel, the lubrication pump of the external cylindrical grinder or the oil pump of the static pressure oil supply system should be started first, and the grinding wheel can only be started after the lubrication of the grinding wheel spindle is normal.3. At the beginning of grinding, the feed rate should be small and the cutting speed should be slow to prevent the grinding wheel from breaking due to cold brittleness, especially in winter when the temperature is low.4. Before starting grinding, t...

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...

Discuss the loading, unloading, and processing efficiency of internal grinding machines

2025-04-11

Discuss the loading, unloading, and processing efficiency of internal grinding machines.Internal grinding machine is a common machining equipment that can not only grind the surface of the workpiece during use, but also perform groove and surface machining on the workpiece during operation. In the existing technology, the internal grinding machine has not achieved full automation in loading and unloading before and after machining.During the machining process of an internal cylindrical grinder, both loading and unloading are manually completed by the operator, which not only increases the workload of the operator, but also leads to a decrease in production efficiency and directly affects the positioning and processing quality of the workpiece.Therefore, it is necessary for its internal grinding machine to be able to automatically load and unload materials, and the equipment should be able to automatically l...

What is the difference between CNC centerless grinding machine and ordinary centerless grinding machine

2025-04-11

What is the difference between CNC centerless grinder and ordinary centerless grinder? I believe this is also a question for many grinder buyers. So let's briefly explain it.1. Simply put, the grinder is automatically controlled by a program (requiring programming).2. When debugging, input the data of the processed workpiece. Once the workpiece is successfully debugged, it can be automatically mass-produced by computer control.3. The characteristics are accuracy, fast speed, and suitable for mass production.4. The requirements for operators are not high, they can start working with a little training.5. The ball screw is driven by a servo motor instead of an oil cylinder.6. High stability, operators rarely need to directly contact the machine tool. ...

What is the formation mechanism of blockage and passivation of grinding wheels

2025-04-11

What is the formation mechanism of blockage and passivation of grinding wheels? Embedded blockage is mainly caused by the mechanical infiltration of grinding debris into the gaps of the grinding wheel, where there is no chemical adhesion between the debris and the abrasive particles. The formation process of adhesive blockage is the chemical bonding between abrasives and grinding particles, and then the abrasives fuse with each other under mechanical adhesion and pressure when grinding carbon steel. When the abrasives rub or grind on the metal surface, the wear of the abrasives begins, that is, the sharp edges of the abrasives begin to be ground away, forming a flat surface on the abrasives. The plane becomes larger and larger, so that the frictional force acting on the abrasive grains is large enough to cause the sand particles on the surface of the grinding wheel to fall off or break, thereby exposing new...

Exploring how to adjust the external cylindrical grinder on the grinding wheel

2025-04-11

How to adjust the external cylindrical grinder on the grinding wheel?1. Take minor adjustments. The amount of adjustment is based on the criterion of restoring the geometric shape of the grinding wheel and producing a good grinding edge after several adjustments. When using a single point dressing tool, the diameter direction of the grinding wheel should be in contact with the axis at an inclination angle of 10-150 degrees. This will cause the single point trimming tool to produce a sharpening effect during regular rotation. The trimming tool with multi-point contact does not need to be tilted at this angle. Change to using the entire end face of the dressing tool in contact with the surface of the grinding wheel. 2. Keep cool.Proper use of coolant can accelerate repair speed and improve repair efficiency. When the diamond dressing tool passes through the grinding wheel, install a coolant nozzle to cover th...
