A surface grinder is a machine tool used to provide precision ground surfaces, either to a critical size or for the surface finish. The typical precision of a surface grinder depends on the type and usage, however ±0.002 mm (±0.0001 in) should be achievable on most surface grinders.
Okamoto Machine Tool Works, Ltd. (ja:岡本工作機械製所) applied self-developed hydraulic pump and hydraulic cylinder to drive the rectangle table and four precision ball bearings on the grinding unit, then possible to move producing machine element by 0.001 mm steps, and it was the first machine realized 1/1,000 mm of precision surface ...
View of a typical setup on a T&C grinder. A Tool and Cutter Grinder is used to sharpen milling cutters and tool bits along with a host of other cutting tools.. It is an extremely versatile machine used to perform a variety of grinding operations: surface, cylindrical, or complex shapes.
Pedal-powered grinding machine, Russia, 1902. A grinding machine, often shortened to grinder, is any of various power tools or machine tools used for grinding. It is a type of material removal using an abrasive wheel as the cutting tool. [1] Each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation.
The tolerances that are normally achieved with surface grinding are ±2 × 10 −4 inches (5.1 μm) for grinding a flat material and ±3 × 10 −4 inches (7.6 μm) for a parallel surface. [4] The surface grinder is composed of an abrasive wheel, a workholding device known as a chuck, either electromagnetic or vacuum, and a reciprocating table.
A schematic of a flat honing machine: 1. Carrier plate 2. Workpiece 3. Outer ring 4. Driven inner ring 5. Grinding wheel. The term is derived from honing cylinders and holes. A flat workpiece surface is processed, hence the word flat; the word honing is used because the cutting speed is low compared to grinding.
