Grinding

126 Machines

Grinding is a fundamental mechanical process for finishing machined surfaces, carried out whenever a workpiece requires a secondary finishing operation to remove excess material and machining residues. On Makinate, you will find a wide selection of used grinding machines, specialized equipment that operates through contact between the workpiece and the tool represented by a grinding wheel, ensuring precision and quality in finishes.

Features of Grinding Machines

Grinding is performed through the contact of the workpiece with the tool represented by a grinding wheel.... Grinding can be carried out both with CNC machines and conventional machinery, offering solutions suitable for both modern production and traditional machining. The most advanced machines are equipped with numerical control or CNC, which allow not only the storage of work programs but also the complete automation of the entire grinding cycle.

Types of Grinding Machines

Grinding machines are divided into three main types based on the shape and surfaces to be machined:

Center-type cylindrical grinders: suitable for grinding cylindrical, conical, and shaped parts, capable of working on both internal and external surfaces
Surface grinders (tangential): ideal for grinding flat surfaces with different machining methods
Centerless grinders: specialized in machining long, small, and thin parts that cannot be clamped between a spindle and a tailstock

Internal and External Cylindrical Grinding

Cylindrical grinding is the grinding machine used for machining cylindrical surfaces as well as conical surfaces. Parts processed with a cylindrical grinder often have complex shapes with multiple surfaces to be machined, an example being crankshafts.

How Cylindrical Grinding Works

In cylindrical grinding, the workpiece is fixed on the spindle, which determines both its rotational motion and translational motion along the transverse axis. The grinding wheel rotates in the same direction as the workpiece. Cylindrical grinding allows for two different types of grinding: internal grinding and external grinding. Sometimes, the same machine can perform both types, increasing operational versatility.

Tangential Grinding for Flat Surfaces

Tangential or surface grinding is a type of grinding machine designed to work on flat surfaces. In tangential grinding, the workpiece does not rotate but only moves along the machine's plane axis. As it moves along the plane, the surface of the workpiece comes into contact with the grinding wheel, which performs the actual grinding operation.

Tangential Grinding Methods

There are two different types of tangential grinding depending on the positioning of the workpiece and the grinding wheel spindle:

Flat tangential grinding: the most common configuration, where the grinding wheel is positioned parallel to the plane
Flat frontal grinding: the grinding wheel is positioned perpendicular to the plane to allow frontal grinding of the workpiece

Centerless Grinding

Centerless grinding is a particular type of grinding used for producing parts that, due to their shape, cannot be machined between centers and supported by the spindle and tailstock. In this type of grinding, the workpiece is placed between two wheels rotating in the same direction.As in lapping operations, the two wheels have different diameters. The smaller wheel drives the workpiece into contact with the larger grinding wheel, which performs the actual grinding. The larger grinding wheel rotates at very high speeds, while the driving wheel rotates slowly. Two types of grinding can be performed with centerless grinders: through-feed grinding and plunge grinding.Centerless grinders are highly complex and technologically advanced machines, mainly used in the automotive sector and bearing industry, where precision and repeatability are essential.
