What is the impact of grinding heat on the machining of cylindrical grinders

2025-04-11

What is the impact of grinding heat on the machining of cylindrical grinders?Causing surface burnout of the workpiece: The surface of the workpiece may be burnt under high temperature.The so-called burnout generally refers to the uneven annealing of the metal material on the surface of the quenched workpiece under the action of grinding heat. As a result, the surface hardness of the workpiece decreases, which affects the performance and lifespan of the parts.The surface of the severely burned workpiece can be seen with the naked eye, presenting a layer of burnt yellow or burnt black oxide film.The surface of the slightly burnt workpiece appears pale yellow. Grinding materials with poor thermal conductivity, such as bearing steel, heat-resistant alloy steel, etc., is prone to burning out.Residual stress and cracks on the surface of the workpiece: When the temperature in the grinding zone reaches a point wher...

Is the grinding method the same for different types of internal cylindrical grinders and its problem analysis

2025-04-11

Analysis of whether different types of grinding methods for internal cylindrical grinders are the same and their problems.1. What is the main consideration when purchasing an internal or external cylindrical grinder? Additionally, can it be replaced by a grinder?The main determining factor for whether to purchase an internal grinder or an external grinder is for actual production needs. If the majority of parts are for internal hole grinding, then it is advisable to purchase an internal grinder; If the majority of parts are cylindrical grinders, then it is advisable to purchase cylindrical grinders.As for the grinder, although it can grind inner holes and outer circles, it has limitations compared to the internal and external cylindrical grinders. So if it is for mass production, it is not recommended to use a grinder because the processing is not good and quality problems are prone to occur.2. Are the grin...

Explain the difference between smooth grinding and general grinding

2025-04-11

The main differences between smooth grinding and general grinding are as follows:1. The grain size of the grinding wheel is relatively fine, generally ranging from 46 # to 60 # during grinding, and from 60 # or above to w10 # during smooth grinding. 2. The linear speed of the grinding wheel is relatively low, reaching 12-20m/s.3. The worktable speed is slow during grinding wheel dressing, reaching 10-25mm/m. 4. The lateral feed rate is relatively small, usually 0.02-0.05mm; During finishing, it is 0.0025-0.005mm.5. The workpiece line speed is low, usually 20-30m/min during grinding and 4-10mrn/m during finishing.6. Non sparking grinding has a high frequency of 1-2 times, while finishing machining requires 10-20 times. Finishing grinding is suitable for machining different machine tool spindles, key shaft sleeves, rollers, plug gauges, bearing rings, etc. ...
