Ultrasonic-assisted grinding processing can effectively reduce the surface roughness and enhance the processing efficiency in the processing of hard and brittle materials. However, the most common ultrasonic assisted grinding is a type of contact ultrasonic grinding where the grinding tool directly contacts the workpiece, which means that it is necessary to accurately control the pre …

In single-pass grinding processes, grinding wheels with conic chamfer are used. That chamfer allows to distribute machining allowance on a larger surface of rough grinding zone. When height of grinding wheel T = 20 mm and grinding allowance ae = 0.20 mm, than angle of conic chamfer χ are very small - less than 1°. In the paper pneumatic measuring method of axial contour of grinding wheel ...
The non-uniform contact lasts almost throughout the whole experiment. Similar non-uniform contact occurred in Fig. 18(b), at start of ELID grinding, strong interaction phenomenon was observed. The interaction phenomenon indicates that the non-uniform contact lasts only 1/3 of the experiment. The interaction phenomenon does not last any longer.

Thickness control by using NCG. NCG is The Non Contact Gauge. DISCO's Fully Automatic Grinder and Grinder/Polisher usually measure wafer thickness in grinding process and control wafer thickness by contact gauge. NCG measure wafer thickness without contact, and has advantage below. NCG avoid the risk of breaking wafer which is weak in load, for ...

Balance head is a key component of grinding wheel auto-balance device. The key issue is to design a balance head with high accuracy and durability. Considering these two factors, a new type of balance head with non-contact driving structure is proposed and described in this paper.
Meanwhile, non-contact ultrasonic grinding could effectively avoid the uneven grinding quality caused by uneven force and grinding fluid aggregation in traditional contact grinding. Non-contact ultrasonic grinding can provide new ideas for ultrasonic grinding of hard and brittle materials.
The paper presents the results of contact and non-contact measurements of external profiles of selected grinding pins. The measurements were conducted in order to choose the appropriate measuring technique in the case of the considered measurement task. In the case of contact measurements the coordinate measuring machine ACCURA II was applied.
For maximum control, an upgrade to in-process thickness measurement with feedback to the grinding cycle in real-time is available. The ADM model offers automated thickness options: multi-point contact probing for multiple wafers grinding or a choice of contact or non-contact continuous in-process measurement for the single wafer.
It is a challenge for grinding internal screw threads due to the narrow space limitation. This paper proposes an automatic tool setting method for grinding internal screw threads with non-contact proximity switch, which can be effectively applied into realistic situation with low cost.
