Surface Grinding Machine

Surface Grinding Machine, a method that has been used for years, is one of the surface improvement processes by smoothing, smoothing, brightening and reaching the correct dimensions of the surface of the workpiece. This method is one of the basic metalworking methods, which includes techniques such as lapping and polishing among other surface improvement methods. This is accomplished by reducing the amount of chip removed.

How is Surface Grinding Made?

The grinding machine is a tool that enables the processing of workpieces by using abrasive stones, which are formed as a result of combining organic and inorganic elements. These machines are used for various purposes such as machining workpieces within the specified tolerance range, eliminating processes such as warping after heat treatment, and removing chips from hardened surfaces.

Traditionally, people used to process tools by working with abrasive wheels, but with the development of grinding machines, this process has evolved further. Today, jet engines, engines of high-pressure automobiles and many precision parts are processed by grinding machines. Without these machines, it would not be possible to process such sensitive and detailed parts.

The main purpose of grinding machines is to process the workpieces in the correct tolerance range and to bring them to the desired shape and size. These machines smoothen and smooth the surfaces of the workpieces by removing the chips thanks to the cutting edges of the abrasive stones. In addition, operations such as chip removal from hardened surfaces are also carried out with grinding machines.

As a result, grinding machines have an important place in industrial production. It plays a major role in the processing of sensitive and detailed parts and is used in many industries. Thanks to grinding machines, high quality and machined parts within the correct tolerance range are produced and productivity increases in industrial production.

Surface Grinding Machines

Surface grinding machines are known as machines for grinding the surfaces of workpieces. In this method, while the stone is rotating, the part is fixed with a magnetic table and the surface of the part is grinded, starting from the nearest point of the stone, until the entire surface is grinded. After grinding, a glass-like surface can be obtained depending on the quality and material properties of the stone.

Surface grinding machines are divided into two groups as horizontal spindle plane grinding machines and vertical spindle plane grinding machines. In horizontal spindle machines, the stone spindle is in the horizontal position and cuts with the grinding wheel, which is the cutting tool. The workpieces are moved to the right and left and back and forth by connecting to the workbench. Chip delivery is achieved by moving the stone head and its precision is 0.01 mm. Horizontal spindle machines are ideal for grinding small-sized parts and also allow the grinding of grooves such as straight channels.

In vertical spindle machines, the stone spindle is in the vertical position and the grinding stone enables the surfaces to be cut. It is used for grinding large-sized, bulky and heavy workpieces, and is also preferred for grinding circular-section workpieces. These looms are moved back and forth and left and right, similar to horizontal spindle looms. However, the grinding wheels used in large-size vertical spindle machines should also be large-sized. Although it provides important contributions in terms of processing, a rougher appearance may occur in terms of surface qualities.

Cylindrical Grinding Machines

There are different types of machines and include many special tools used for grinding workpieces. There is a type of machine that is often used for grinding workpieces with cylindrical and conically ground outer surfaces. These machines are also used for grinding cylindrical surfaces such as pins, shafts, sleeves. In addition, hole grinding operations can also be done using these machines. Grinding of holes is carried out using special hole grinding apparatus.

Cylindrical grinding operations are performed by connecting the workpieces in different ways between the chuck and the chuck spot. When the workpieces are too long, the bearings provide support to the workpieces. Cylindrical grinding processes are divided into different classes such as tapered external grinding, cylindrical external grinding, hole grinding, crank and cam gear grinding.

Crank and cam grinding machines are machines used in industry for special purposes and are frequently preferred especially in the automotive sector. Gear grinding is performed over the diameter of the section circle, which is one of the most important structural features of the gear wheel, which is the power and motion transmission element. Gear wheels work in contact with each other on this diameter.

Internal internal grinding is the opposite of cylindrical grinding and generally involves grinding internal surfaces. In this process, the stone geometries are in conical or cylindrical shapes and are supplied in accordance with the hole geometry.

CNC Grinding Machines

Precision and surface quality are extremely important in plane grinding and cylindrical grinding. Therefore, numerical control technology has been designed in accordance with these processes. However, the use of CNC in grinding is less common than in other industries. Some manufacturers have developed their own CNC systems to solve grinding-related problems.

Standard control designs used in lathes and machining centers are not used in grinding machines. Therefore, different control systems have been designed for grinding machines. In addition, special grinding cycles are required. For example, processes such as waiting, gradual feed increment, oscillation, routine and grinding can be incorporated into special grinding cycles.

In grinding operations, automatic cutter compensation must be made after grinding the grinding wheel and the operation speed must be continued without interruption. Therefore, control systems used in grinding machines must support these features.

As a result, special control systems and grinding cycles are required to achieve precision and surface quality in grinding operations. Therefore, manufacturers develop their own CNC systems and design different control systems on grinding machines.

Centerless Grinding Machines

Centerless grinding machines are machines that allow the workpieces to be grinded by passing them between two stones on the delivery slide without binding. The workpiece rotates by taking the speed of the cutting stone and moves like a screw with the advancing effect of the lead stone. The cutting wheel, on the other hand, starts the rotary operation as soon as the workpiece comes into contact with it and performs the grinding operation.

The drive stone is an important component that reduces the rotation speed of the workpiece and enables it to move forward. Therefore, the speed of the lead stone is quite low. Centerless grinding processes can be applied in two different ways as longitudinal grinding and plunge grinding.
