As the cost of this attachment is less, we can keep this idle when we dont have. A pressure vessel is defined as a container with a pressure LearnMech.Com is a Mechanical Project-oriented platform run by Sachin Thorat who is a B-Tech Graduate in Mechanical Engineering. I have to say the tool post grinder works extremely. It may not display this or other websites correctly. Something not often considered is the lenght of the spindle from wheel to belt, a center in the TS is often needed on long work, but then the spindle hits the TS base, I doubt your mini lathe has the crosslide travel to clear the TS and twist the grinder to clear, and still contact the work. Good post. This whole arrangement is fixed on the, carriage where the component rests. It sure looks a lot handier, but I suppose a great deal would depend on what type and grade of "mounted points" (grinding wheels potted onto arbors) are available. To avoid this heavy investment and also to fill our.

This attachment is not used for taper job to grind but it can grind by using extra taper thread turning attachment. I learned lot of things. Having used a few different TP grinders over the years there are things that add or subtract from success. Does anybody know of a company that sells a set up like that? I am considering buying a toolpost grinder for my lathe from Little Machine Shop. Learn how your comment data is processed. The attachment is compact and rigid in size. well. He also likes to write articles related to the mechanical engineering field and tries to motivate other mechanical engineering students by his innovative project ideas, design, models and videos. It would be much simpler if the grinder could be held in one of the tool holders on my AXA quickchange toolpost. One thing that i have had good success with when turning small diameter thigs like needle valves is to spin the shaft in your chuck, and use a hand file to form the tapered point. It is used to, grind the machining surfaces to super Finish and accuracy. 1. It would also be angle adjustable and could be fed at an angle. this one fits in the boring bar holder on an AXA toolpost. Register today and take advantage of membership benefits. Mount a TP grinder to the compound, if that type can't be modified to do that don't buy it. For example, bore of industrial valves, outer diameter of spindle of varies machines. The rotation of the grinding wheel will be opposite to, Depth of cut may be given by cross slide, and the longitudinal movement will be. Remember, this is only for needle valves and perhaps very small (as in 3/8" diameter) valves vor i.c. Our project is design and fabrication of Multi Use Tool Post Grinder.

The, above machinery cost will be more, and also unless we have lot of similar jobs, we equity, keep these costly machines idle. My first model engine. http://littlemachineshop.com/products/product_view.php?ProductID=2001&category, http://www.deansphotographica.com/machining/projects/filingrest/filingrest.html, Finishing piston o.d. Normally depth per cut will be 0.02 to 0.05 MM. with toolpost grinder, Protractor base for grinder mounted on cross-slide, Small heat treat or ceramic oven and toolpost grinder, 18 Cylinders Isotta Fraschini (straight six-cylinder x3 ), Another Tiny I.C. Additionally, he has interested in Product Design, Animation, and Project design. retrieve your Don't know if I was using the wrong grade, grit, or composition, but after trying a number of different wheels and speeds, I decided it must be a black art that I didn't want to invest any more time in. It can be used as an internal, and external Grinder by fixing the attachment on the Carriage of a centre Lathe. I had a small Dumore grinder and could never get a very good finish with it. removes the material, but in this process, a grinding wheel is used to super finish the jobs, This attachment is fixed on the lathe carriage, where the compound rest rests. 1. IMO mounting a TP grinder as pictured to a QCTP is asking for poor results. 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. It is just like a boring bar. Sachin is a B-TECH graduate in Mechanical Engineering from a reputed Engineering college. The only change I would make is to have a totally enclosed motor to keep out the grit. First is rigidty, the more rigid the better, this will show in the surface finish right away, waves, scallops, lines, mean lack of stiffness. on tool post. The, principle parts of this attachment are main body, Spindle shaft, bearings, rope pulley and, Generally some components in engineering field require high surface finish and, accuracy. Currently, he is working in the sheet metal industry as a designer. The, spindle of the attachment will be parallel to the lathe spindle. You can also use this method to reduce the diameter of small shafts without having to worry aboutthe tool digging in because of flexing.

Where the motor is on, the spindle and the grinding wheel will be rotated, on the RPM of about. This attachment is used on centre lathes. 3. The operation is similar to grinding operation. So, with this in mind, I set off to build my own. Maybe for the small amount of grinding I want to do, this is what I want. 1. By varying the pulley sizes I can get a high end speed of over 10,000 rpm if needed. 2. I would be looking to turn the mounting through ninety degrees , and mount it on the tool post for tapers , as I have only 2 3/16 " over my saddle . You are using an out of date browser. It can be used on any lathe by small change in centre heights. requirement in grinding of such above jobs, we can manufacture this attachment. Wherever grinding finish is required it can be used. A grinding wheel is mounted on the spindle which, is supported by two bearings, and is rotated by a motor through V rope in high, also rotating on the chuck, Material will be removed according to the cut which we, select. Introduction to Pressure Vessels Vessels, tanks, and pipelines that carry, store, or receive fluids are called pressure vessels. My shop has an air supply. I've not had good a experience with toolpost grinders. Thanks for sharing. As the feed is given automatic, 0.8 micron finish may be achieved. Grinding inside the bore in any size of body can be done.
