Design and Construction of a Bench Tool-Type Grinder

Abstract

A bench grinder is a type of bench-top grinding machine used such as those used for sharpening our knives, cutting tools, clean or polish work-pieces, grinding softer metals, like aluminium and perform other rough grinding. This study therefore is aimed at designing a bench tool grinder with good efficiency, better versatility for better productivity. The bench tool type grinder was constructed with the use of an adjustable electric motor. The fabrication of all the parts of this machine was done using fabrication technique such as welding and brazing. And the software prototype presented herein was designed using the AutoCAD. The use of mild steel was preferred in the design of the bench type grinder because it’s cheap and wide varieties are available with different properties. The result presents that welding carbon steels with carbon content greater than 0.3% requires special precautions to be taken. However, welding carbon presents for fewer problems than welding stainless steels. While the corrosion resistance of carbon steel is poor (i.e they rust), mild steel is therefore found to be more corrosion resistance. The construction of the designed machine was simple, and they are cheap to maintain hence, its acquisition is affordable to all scale of users, ranging from the work-shops to even the wood-working shops. The use of high strength materials ensures its long life and durability. The use of goggle is highly recommended for engineer as safety measures while constructing bench type grinders as wielding can easily cause damage to the eye if not protected.
