The PG-9BHD is a hydraulically-driven centerless Form grinding machine designed to form multiple components from rod or preformed parts. Examples of parts ground on this machine include carbon fiber and Teflon® (PTFE) components, golf balls, check valves, drumsticks, deodorant balls, pen nibs, ceramic balls, rubber balls, billiard balls, and more.
While the downside of the centerless grinding process is you cannot have as many multiple axes operating on the workpieces, there are many machine parts where the process addresses the limitations of machining in terms of dimensions, materials, and surface finishes. Hence, where machining ends, centerless grinding begins.
grinding. In centerless grinding, the workpiece rotates between a grinding wheel and a regulating drive wheel. The work is supported from below by a fixed work-rest blade. The two basic modes of centerless grinding are "thru-feed" and "in-feed" or "plunge" mode. In the thru-feed mode, the work proceeds in the axial
With reference to FIG. 1, a centerless grinding machine 10 has a machine base 11, supporting a stationarily mounted workrest 12. The workrest 12 is conventional, and includes a work support blade 13 which helps to cradle a rotary workpiece 14 during the grinding process.
Centerless grinding is a machining process that uses abrasive cutting to remove material from In end-feed centerless grinding, the workpiece is fed axially into the machine on one side and comes to rest against an end stop; the grinding Process · Types · Through-feed.
The machine (B) with the grinding wheel (diameter 355 mm, width 150 mm) is a high precision centerless grinding machine in which a special cast iron material having ultra-low thermal expansion coefficient of 1–2 × 10 −6 /°C was applied to the bed and main machine structure.
For wide machines, coarse, medium and fine grit wheels can be combined. Very fine grit wheels are available. Stainless Steel - A Better Way . A type of centerless grinding that NT wheels handle very well is stainless steel. Stainless has always been a difficult family of steel to grind, especially the austenitic 300 series.
Automated Infeed/Thrufeed Centerless Grinding System. The GT-610 Automated Infeed/Thrufeed Centerless Grinding system can be custom fitted with automation. This system is the ideal option for when infeed applications do not require a CNC dresser and for the vast majority of thrufeed applications.
production through-feed centerless grinding is a lot more compli-cated than the setup shown in Figs. 3 and 4. Figure 3~a! shows the front view of a through-feed centerless grinding machine with 400 mm diameter grinding wheel, 80 mm diameter workpiece, and 50 mm center-height of the workpiece. An XYZ Cartesian coordinate system is ﬁrst deﬁned.

Grinding Machines Grinding Machines are also regarded as machine tools. A distinguishing feature of grinding machines is the rotating abrasive tool.
Increasingly, though, the advantages of centerless grinding, such as rapid rounding and accuracy, are finding application in shops that run relatively shorter job lot sizes. The enabler for this is the application of CNC and servomotor technology to the centerless grinding machine.
