Hydraulic Cylindrical Grinding Machine

Traditional cylindrical grinding is one of the most critical equipment in the entire finishing process of the metalworking industry. After forming, cutting, and other complex machining, many workpieces will go to this step, and the process of cylindrical grinding is used to produce a smooth finishing surface on the cylindrical internal or external surface. This is a commonly used grinding process, through the spinning wheel is covered with rough particles, which cuts chips of metallic or non-metallic substances from the workpiece, and smooth the surface of the cylindrical workpiece. In all grinding processes in the entire grinding range, such as surface grinding, centerless grinding, cylindrical grinding is one of the most common grinding in the industry that has been in existence since the longest history, and now among the various grinding procedures. With the help of a computer-controlled system, the hydraulic cylindrical grinding machine is in the finishing process, which uses a rotational abrasive wheel to smooth the surface of metallic or non-metallic materials, and provide a fine physical state by removing layers and impurities on the surface of the workpiece.

Cylindrical Grinding & Clamping

The cylindrical grinder is one of the grinding machines used to shape the outer side of the workpiece by the grinding mechanism. Cylindrical grinders can process various shapes, but the object must have at least a central axis of rotation, so that it can rotate concentrically. This includes, but is not limited to cylindrical shapes, such as cams, ellipses, crankshafts, etc. The basic definition of cylindrical grinding is that the machine must have four key functions: first, the workpiece must continuously rotate. Second, the grinding wheel must continuously rotate. Third, the grinding wheel moves forward and backward toward the workpiece. Finally, move the workpiece relative to the grinding wheel. Today, most cylindrical grinding machines use these four movements, while there are still grinding machines that use only three of these four movements for machining.
 
In the grinding process, the clamping system and the chuck are the key components in the cutting process of the machine tool. Some hydraulic-based clamping systems are very old-fashioned, but they are practical and popular because of their special functions. The hydraulic clamping or hydraulic work holding can be widely used in metal processing because they are suitable for daily use in grinding, milling, EDM and other machining processes. Hydraulic technology can achieve high precision, rigid clamping, and longevity. For polishing and grinding, these processes will obtain the intended surface for functional purposes, which is designed and programmed by engineering staff as planned.


Hydraulic Cylindrical Grinders

Furthermore, the mechanical structure of the hydraulic cylindrical grinder is complicated, since the mechanical structure of the cylindrical grinder is composed of a grinding wheel and a workpiece holding device as a basic device and many other auxiliary accessories. During the machining process, the clamping device will clamp the material in place when processing the material. The hydraulic clamping mechanism can be implemented in two ways: one is to fix the ferromagnetic parts in place by magnetic chucks, and for non-ferromagnetic and non-metal parts, they can be fixed in place by vacuum or mechanical methods. The clamping mechanism is essential for the entire processing process because only with a strong positioning and clamping device can the work be completed with ideal quality.


Accuracy & Precision

In fact, the typical accuracy of a hydraulic cylindrical grinder depends on the type and application, and in most cases, most cylindrical grinders should be able to achieve a certain accuracy value. In other words, the ID or OD cylindrical grinder is a machine tool used to provide precision grinding surfaces (reaching critical dimensions or surface finish). Therefore, the typical accuracy of a cylindrical grinder depends on the type and application. Cylindrical grinder includes both the types that use centers and the center-less types. Cylindrical grinders can have multiple grinding wheels for different purposes. Rotating the workpiece and passing it through one or more wheels to form a cylinder. It is used to manufacture precision rods, tubes, bearing races, bushings, and many other parts. When manufacturing various high-precision shafts, center grinding is usually used. The primary function of this kind of machines is to grind the centers of a shaft very precisely. An accurate round center hole on both sides ensures a position with high repeatability accuracy.
