Material Removal Rate

Material removal rate (MRR) is a measurement of the volume of material that is removed during a CNC machining operation, typically measured in cubic inches per minute (in3/min) or cubic millimeters per minute (mm3/min).

Feed rate

Feed rate refers to the rate at which the cutting tool or workpiece is moved in relation to the cutting surface in a CNC machine, and is a critical factor in determining the efficiency and effectiveness of the machining process.

Finish grinding

Finish grinding is a type of CNC grinding process used to create a smooth, polished surface on a workpiece, and may be used to improve the aesthetic appearance or functionality of the finished product.

Fixed wheel head

A fixed wheel head is a type of grinding wheel used in CNC machining that is mounted permanently to the machine and cannot be adjusted or moved, and may be used for specific applications or materials.

Grit

Grit refers to the size or coarseness of the abrasive particles used in a grinding wheel or other cutting tool, and may be measured in microns or mesh size.

Hardness

Hardness is a measure of the resistance of a material to deformation or penetration, and may be an important factor in determining the appropriate cutting tool or machining parameters for a given material.

Horizontal Machining Center

An HMC or horizontal machining center is a type of CNC machine tool used for high-precision machining of complex parts or components, and features a horizontally oriented spindle and workpiece bed for improved stability and accuracy.

Honing

Honing is a type of CNC machining process used to create a precise, smooth surface on a workpiece using a rotating abrasive stone or tool, and may be used to improve the fit or functionality of components such as cylinders or bearings.

Hybrid grinding

Hybrid grinding is a type of CNC grinding process that combines two or more different grinding techniques or tools in order to achieve a specific result or optimize the machining process.

Hydrostatic bearings

Hydrostatic bearings are a type of bearing used in CNC machines that rely on a fluid or gas to provide a stable, low-friction support for rotating components such as spindles or tool holders.
