Universal Cylindrical Grinder
A universal cylindrical grinder is a type of grinding machine designed for precision grinding of cylindrical or round parts. It is a versatile tool that can be used for a wide range of functions, including surface grinding and deburring. Universal cylindrical grinders can be used in a variety of machining operations, from simple to complex.
Features
Universal cylindrical grinders are typically equipped with features that make them one of the most versatile and powerful machines available. These features include:
-Precision grinding: Universal cylindrical grinders typically feature a workhead that can be adjusted to accommodate different workpiece diameters, as well as to provide a slow rate of travel to ensure that the grinding operation is performed with the highest degree of accuracy. Some universal cylindrical grinders also feature an additional grinding head that allows for the grinding of inner and outer diameters simultaneously.
-Multiple grinding techniques: Universal cylindrical grinders are capable of performing operations such as plunge grinding, cylindrical grinding, and profile grinding. Plunge grinding is a technique that involves grinding a workpiece by feeding it directly onto the grinding wheel. This technique is often used for producing parts with a consistent wall thickness or for creating slots or profiles. Cylindrical grinding, on the other hand, utilizes a rotating abrasive wheel to grind outward from the center of the workpiece. Profile grinding involves grinding the sides of the workpiece in the same manner as cylindrical grinding.
-Swing-over table: Many universal cylindrical grinders feature a swing-over table that provides unrestricted access to the grinding wheel and workpiece. This feature allows the workpiece to be moved out of the way to accommodate larger parts and multiple pieces.
-Complex parts: Universal cylindrical grinders are capable of grinding complex parts, such as cams and internal threads and grooves. They can also be used to sharpen specialty cutters and form profiles on parts.
-Wide variety of materials: Universal cylindrical grinders can be used to grind a wide variety of materials, including steel, cast iron, aluminum, stainless steel, cobalt, and plastics.
-High accuracy: The rigidity and precision of universal cylindrical grinders provide high levels of accuracy, even when grinding small parts.
-Multiple applications: Universal cylindrical grinders are used in a variety of industries and applications, including automotive, industrial, aerospace, and medical.
Technical Specifications
Universal cylindrical grinders vary in size and features, with various configurations and features available. Common features and technical specifications include:
-Motor: Low speed motors (from 3 to 10 hp) are typically used to produce a higher level of torque. High speed motors (from 25 to 75 hp) are used for improved accuracy and higher feed rates.
-Wheelhead: A wheelhead is the main component of a universal cylindrical grinder. It houses the grinding wheel, which is the main cutting tool of the machine, as well as other components such as the table, the feed drive, the headstock, and the tailstock.
-Wheel: The grinding wheel is typically diamond or abrasive-treated and is available in a variety of sizes, shapes, and abrasive materials. Diamond wheels provide a high level of accuracy and come in a variety of sizes, from 3 to 8.
-Controls: The majority of universal cylindrical grinders feature a computer numerical control (CNC) control system, which provides accuracy and control. The CNC control system allows operators to easily program specific cutting parameters, such as the feed rate, depth of cut, and grinding angle.
Conclusion
Universal cylindrical grinders are versatile and powerful grinding machines that are used in a variety of machining operations. They are typically equipped with features such as precision grinding, multiple grinding techniques, swing-over tables, and complex parts. They are also capable of grinding a wide variety of materials, with high levels of accuracy. Universal cylindrical grinders vary in size and features, with various configurations and features available.
