10 Things to Know About Creep-Feed Grinding

6. Intermittent dressing is becoming more acceptable. Because the material removal per pass is so great in creep-feed grinding, aluminum-oxide wheels used in this process tend to require continuous dressing. A dressing wheel applied to the grinding wheel as it is grinding keeps the wheel sharp at all times.

Grinding with controlled kinematics and chip removal

1. Introduction. In cylindrical and centerless infeed grinding processes the material removal occurs by an infeed cycle composed of several stages with constant (stepped) infeed rates, normally: roughing, finishing and a final spark-out, constant or stepped workpiece speeds and constant grinding wheel speed.

Inventions | Free Full-Text | The Effect of Grinding Wheel …

After infeed grinding, spark-out grinding is performed in order to reduce the elastic deflection of the grinding system, followed by the rapid retraction of the slide to the home position. To study the effect of the wheel's contact stiffness on the plunge grinding process, this paper focuses on a primary grinding cycle consisting of plunge ...

Advances in centerless grinding technology

In throughfeed centerless grinding of precision rollers (ø15 × 20 mm), the advanced technology makes possible the production of rollers with roundness accuracy of 0.1–0.3 μm and a throughput of 250–350 pieces/min. Infeed centerless grinding can produce rollers with size control of 0.1 μm.As indicated in Fig. 1, the average fuel …

Continuous variable feed rate: a novel method for improving infeed …

This paper presents a novel method for improving infeed grinding processes based on the application of continuous variable feed rate (CVFR). Nowadays, infeed cycle configuration is defined by selecting constant feed rates and stock removals for each consecutive stage, normally roughing, finishing, and a final spark-out, for the …

Dressing of hybrid-bonded graded diamond grinding wheels

For tool grinding, an optimization potential in terms of productivity is available using graded grinding wheels. This is especially the case when grinding flutes in cemented carbide. Due to the properties of the cemented carbide, high radial wear occurs. Depending on the geometry of the flute, the radial wear varies along the engagement …
