Cylindrical external - internal grinding machines

52 Machines

Internal and external cylindrical grinders are specialized grinding machines designed for the machining of cylindrical and conical surfaces, ensuring precision and high-quality finishes on components with complex geometries. At Makinate, you will find a wide selection of used cylindrical grinders, professional machinery ideal for processing components such as crankshafts, drive shafts, and other rotating surfaces that require strict dimensional tolerances.

Features of cylindrical grinders

Cylindrical grinding machines are designed to work on cylindrical and conical surfaces.... Parts processed on a cylindrical grinder often have complex shapes with multiple surfaces to be machined, such as crankshafts. This type of machine is a fundamental solution for achieving precise finishes on rotating components in the mechanical industry.During cylindrical grinding, the workpiece is clamped on the spindle, which controls both its rotational movement and translational motion along the transverse axis. The grinding wheel rotates in the same direction as the workpiece, ensuring controlled and uniform material removal. This coordinated motion system allows for perfectly cylindrical or conical surfaces with extremely high dimensional precision and surface quality.

Internal cylindrical grinders

Internal cylindrical grinders are specialized for machining internal cylindrical surfaces, such as precision holes, bearing seats, and other hollow geometries that require precise dimensions and controlled surface finishes. This type of grinding uses smaller-diameter wheels mounted on specific spindles to reach and machine the internal surfaces of components.

Applications of internal grinders

Internal grinding is commonly used in the production of:

Bearing seats: to ensure tight tolerances and optimal surface quality
Precision holes: where dimensional accuracy is critical
Cylinders and bushings: for hydraulic and pneumatic applications
Components with cylindrical cavities: requiring precision finishes

External cylindrical grinders

External cylindrical grinders are dedicated to machining external cylindrical surfaces, ideal for finishing shafts, pins, rollers, and any components with external rotating surfaces. This type of grinding ensures strict dimensional tolerances and excellent surface finishes, essential for the proper functioning of mechanical assemblies.

Versatility of combined machines

Cylindrical grinders are also distinguished by the ability to perform two types of grinding: internal and external. Sometimes the same machine can perform both types, providing a complete and versatile solution that allows machining both internal and external surfaces without needing separate machines.

Technology and numerical control

Modern cylindrical grinders are equipped with numerical control (CNC). The implementation of CNC offers several advantages:

Program storage: to repeat identical operations with extreme precision
Full automation: reducing human errors and increasing productivity
Higher accuracy: optimal control of machining parameters
Repeatability: ensuring consistent quality even in large production runs

Components with complex geometries

Cylindrical grinders are particularly suitable for parts with complex shapes and multiple surfaces to be ground. The ability to program automatic cycles and simultaneously manage internal and external surfaces makes these machines indispensable for production requiring high-quality standards.
