About cylindrical grinder machinery

Types of cylindrical grinder machineries

A cylindrical grinder machine is used to grind the outer, inner, and tapered cylindrical surfaces of various materials. Purchasing decisions for this machinery often hinge on the end-use or application. Thus, it's important to know that different types exist. Let's take a closer look at some of the most commonly used ones.

  • General purpose cylindrical grinder machine: This grinder machine is the standard model of the cylindrical grinder. Manufacturers use it to produce cylindrical workpieces with high precision. It's mainly used for general purposes; hence, it's compatible with a wide range of settings and various material types.
  • Internal/external cylindrical grinder: This grinder machine is used to grind the outer and inner surfaces of cylindrical workpieces, respectively. An external cylindrical grinder machine is commonly used for routine cylindrical shaping and smoothing. Internal grinders, on the other hand, can get into the cylindrical holes for grinding purposes. It's worth noting that the two are not distinct types. One workpiece can be accessed by internal grinding, while external grinding can only access the outer surface of the workpiece.
  • Universal cylindrical grinding machine: It combines the functions of an internal and external cylindrical grinder. Manufacturers use it to grind both the inner and outer surfaces of a workpiece. As a result of its ability to grind both surfaces, it offers better accuracy for complex workpieces.
  • Roll cylindrical grinder machine: This machine's primary purpose is to grind cylindrical rollers. Typically, these rollers have a rough surface, so the univ. grinder machines improve the surface finish for better precision and control. Also, their over-sized grinding wheels are able to accommodate the large size of the roller.
  • Centerless cylindrical grinder: Unlike the traditional cylindrical grinders that rely on centers to hold and clamp the workpiece, this grinder clamps the workpiece between a driving wheel and a grinding wheel. It offers efficient removal of materials and high processing speeds.
  • PLC-controlled Robotic cylindrical grinding machine: This type of grinder is controlled by PLC (Programmable Logic Controller). It highlights the growing significance of automation and technology in modern machinery industries. Robotic cylindrical grinders offer precision and higher levels of automation compared to their PLC-less counterparts.

Cylindrical grinder machinery specifications and maintenance

Cylindrical grinder machinery specifications will depend on the specific model being manufactured and the application requirements. Some of the key cylindrical grinder machine specifications include the maximum length and diameter of workpieces the machine can handle., grind wheel dimension and motor power.

Generally, maintenance usually involves routine inspection to ensure that all the parts are intact and there are no signs of damage. The procedures may include lubrication of the grinding spindle and other moving parts to keep the machine constant during operation. Also, as highlighted earlier, the grinding machine could either use diamond or CBN wheels, which offer different maintenance procedures. CBN grinding wheels are designed for high durability and long-life span, thus requiring minimal maintenance. However, the wheel should be regularly cleaned to get rid of the residue of the material being ground. It can be done by running a clean aluminum oxide grinding wheel or by using ultrasonic cleaning methods. On the other hand, diamond grinding wheels require more frequent maintenance due to the wear and tear of the diamond particles. They can be cleaned using a wire brush after any grinding activity to maintain their cutting efficiency. Alternatively, they can be cleaned using solvents or cleaning compounds. Sometimes, manufacturers recommend dressers to restore the diamond wheels’ shape and profile.

Moreover, the cylindrical grinder machine may be regularly lubricated to minimize wear and tear and prolong the machine's life. Lubrication can be done by oiling the guideways and other moving parts of the grinding machine. The grinding machine should be regularly calibrated to ensure precision and accuracy while grinding. Finally, the machine should be cleaned on a regular basis to remove any buildup of debris or dust. This is important to prevent overheating of the machine components.
