The coolant penetration in grinding with segmented wheels—part 1: mechanism and comparison with conventional wheels
This paper aims to study the mechanism of coolant penetration into a wheel-work contact zone when a segmented or conventional wheel is used in surface grinding. Based on the principles of fluid motion and considerations of spin-off and splash, analytical models for both conventional and segmented wheels were developed for predicting the power of pumping coolant into the contact zone. It was rev...
متن کاملFixed-Load Electrolytic Dressing With Bronze Bonded Grinding Wheels
In electrolytic in-process dressing (ELID), a metal-bonded grinding wheel is dressed as a result of anodic dissolution. In this paper we describe experiments to evaluate the potential for ELID on bronze wheels in fixed-load grinding applications. A constant-force grinding apparatus was used to determine appropriate ELID conditions for a 10-20 \xm bronze bonded diamond grinding wheel used to mac...
متن کاملIn-Process Electrical Dressing of Metal-Bonded Diamond Grinding Wheels
A new development of hybrid in-process electrical dressing of metal-bonded diamond grinding wheels is proposed in this paper. The electrical dressing method is used for overcoming the limitations of the conventional dressing methods available in relation to a super-abrasive wheel because of the hardness of its abrasive grains and the durability of its bonding material. The proposed hybrid in-pr...
متن کاملNew Diamond Grinding Wheels with Electrically Conductive Cutting Edges
The application of an electrically conductive diamond material to a new type of grinding wheel whose cutting edges possess electrical conductivity has been tried in this research work. Firstly, electrical discharge machining is applied on a solid surface of an electrically conductive CVD diamond film to create protrusions like cutting edges. Secondly, it is confirmed that the EDMed surface of t...
متن کاملGrinding of Microstructures in Brittle Materials with Multiple Microprofiled Grinding Wheels
INTRODUCTION The manufacturing of complex shaped microstructures on microsystem parts in brittle materials provides a high geometrical accuracy [1]. This requirement can only be met by using microgrinding processes. There, metal bonded diamond grinding tools offer a remarkable potential due to their favorable wear behavior [2]. However, the dressing of complex microprofiles on these tools is no...
