01.05.2020 · 1. Introduction. Grinding is a key process to achieve the high surface quality and surface accuracy of mechanical production [,, ].In particular, due to the features of large grinding depth, slow workpiece speed and high material removal rate (MRR) [], creep feed profile grinding is becoming widely applied for precision manufacturing the high-valued parts such as aero-engine turbine blade ...

Collets and chucks are used for grinding workpieces that are either too small for center points or require one end to be featured or profiled. Chuck and collet systems are dynamic workholding systems. Unlike centerless and between-centers setups, where the setup is stationary, the workpiece moves with the chuck or the collet.

While machining one part, the second workpiece spindle simultaneously loads / unloads and aligns another part. The machines are optimised for automatic loading with a standardised, cost-effective combination of pallet conveyor and gantry loader. By using an optional high-speed grinding spindle (HS), it is even possible to grind gears with interfering edges which require a tool diameter of 55 ...

The non-uniform grinding conditions due to the tool and workpiece geometries lead to the complexities of the chip geometry and topography characteristic in gear profile grinding.

Graphical Profile Grinder DV-1 is a state-of-the-art digital machine featuring the use of a CCD camera for automatic on machine measurement and automatic compensation, and can solve problems encountered by a conventional projector such as quality fluctuation, ultrafine workpiece grinding and efficiency. The automatic wheel changer (ATC) system and automatic workpiece changer (AWC) system ...

Grinding wheel wear is an important measured factor of grinding in the manufacturing process of engineered parts and tools. Grinding involves the removal process of material and modifying the surface of a workpiece to some desired finish which might otherwise be unachievable through conventional machining processes. The grinding process itself has been compared to machining operations which ...

The continuous profile grinding of tooth flanks is done by using a globoid worm-shaped grinding wheel which surrounds a part of the workpiece. The dressing (profiling) is made with a diamond-coated dressing wheel which nearly has the shape of the workpiece to be produced (i.e., it is a dressing gear). The globoid worm grinding wheel can only be used for one specific workpiece geometry ...

Moreover, the grinding gap must narrow in axial feed direction to decrease the workpiece diameter. This is achieved by profiling grinding wheel into corresponding zones or pivoting the control wheel. The grinding wheel is commonly profiled and sharpened by stationary or rotating diamond dressing tools.

Ultra-accuracy mold parts, advanced profile realizes "SHINING" surface. Amada is the world leader in CNC Optical Profile grinding. This technology has evolved radically over the decades. Historically, and even now, grinding specialists have labored in darkened grinding rooms .

The PROFILE LINE CNC tool grinding machine is suitable for efficient production of highly complex interchangeable cutting insert geometries. It can handle sintered indexable insert blanks from an internal diameter of 3 mm and a outer diameter of up to 50 mm; rotation-symmetric tools of lengths from 1 to 100 mm can be handled efficiently.

01/01/1987 · Analysis on the workpiece with a flat was done to bring out the effect of an initial in centre/ess grinding irregularity on the generated profile. This particular choice was based on some earlier investigations which revealed that a specimen with a flat provides a sound basis for evaluating the rounding ability of the centreless grinding machine-workpiece system under uniform in-feed ...

Grinding wheels with vitrified bonds are usually dressed with profile rollers that correspond to the finished workpiece profile. Materials that are difficult to machine, such as nickel-based superalloys like those used in aerospace jet engines, can today be economically processed with electroplated or vitrified CBN grinding wheels.
