Abstract
Everyone knows a tool post grinder is one mighty handy item to have as an addition to a lathe, how ever, if you ever priced one, you know they run in to some serious mounts of money. So, with this in mind, I set off to build my own. Pictured below is the outcome of that project. I have to say the tool post grinder works extremely well. By varying the pulley sizes I can get a high end speed of over 10,000 rpm if needed. The only change I would make is to have a totally enclosed motor to keep out the grit.
INTRODUCTION
Our project is design and fabrication of Multi Use Tool Post Grinder. It is used to grind the machining surfaces to super Finish and accuracy. It can be used as an internal and external Grinder by fixing the attachment on the Carriage of a centre Lathe. The principle parts of this attachment are main body, Spindle shaft, bearings, rope pulley and grinding wheel etc.
NEED FOR ATTACHMENT
Generally some components in engineering field require high surface finish and accuracy. For example a cylindrical part requires high finish inside the bore or outside the body, it requires cylindrical grinding machine and centre less grind machine. The above machinery cost will be more, and also unless we have lot of similar jobs, we equity keep these costly machines idle. To avoid this heavy investment and also to fill our requirement in grinding of such above jobs, we can manufacture this attachment.
