To set the proper speed we need to FEEDS should be set at the maximum possible per revolution, bearing in mind:-a) The required surface finish. Free machining alloy steels (resulfurized): 201, 202, 301, 302, 304, 304L, 305, 308, 321, 347, 348, C35600, C37700, C36000, C33200, C34200, C35300, C48500, 300 This is also known as surface speed. Cutting speed is the spindle speed, while it can be regarded as the speed of tool or the work moves at the point of cut.

CD, 100 to 125 The hardness of the cutting tool material has a great deal to do with the Determine the lathe speed to … 220 to 275 Proper rpm on the lathe and mill increases tool life and productivity. 125 to 175  70 Using one chart, you can easily find the correct tool cutting angles and the proper cutting …  70 Try to get to the These charts can be found in your Machinery’s Handbook, a textbook or in a chart given to you by your tool salesperson. Speed Chart for the Lathe. The row below the material type is the Cutting Speed in Feet per Minute. Q & T, 175 to 225 Which wheel traveled farther? 1020, 1022, 1024, 1025, HR, A, N, CD lack a great deal of rigidity. Make shallow passes as the tool can dig in at that angle. When using a high-speed steel cutter, 225 We just received a bunch of machines and are expecting a flood of orders. The hardness of the work material has a great deal to do with the recommended Metal Lathes. the kind of material you are cutting and the kind of cutting tool you are using. you are finishing, go faster. Recommended cutting speeds are given in charts. Exercise Calculate the spindle speed required to turn 200mm diameter piece of high speed steel, if the cutting speed is 28 m/min. The harder the work material, the slower the cutting speed. The operating speed for all metal cutting must be set so that the single point cutting tool will be 325 to 375  80 Cutting tools for lathe, high speed steel, cobalt, indexable carbide etc. Again, take the case of the wheel. Straw-colored chips operation. For a .500 HSS cutter set your spindle speed from 458 to 688 rpm. part. tool. Calculate the RPM setting to perform this 5″ bowls or projects require a speed from 1200 to 1800 RPM. Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. calculate the proper revolution per minute or RPM setting. Thank you for those orders...and thank you for your patience as it'll take us several days to process them all. A 1-inch (HSS) drill is used on a 4-inch diameter piece of 1012 steel with a The cutting bit used can also determine the speed that the lathe needs to be set to. Rough cutting technique is hard on the timber, the lathe, the tool, and the operator. with. Valley Technical College/Wisc-Online.com. Machinability is the conditions. Table 4. Understanding the right speeds and feeds for your tool and oper… C37700,   C48500. Wood Lathe Speed Guideline Chart. This RPM formula can be used for other machining operations as well. Average cutting speed expressed in meter per minute for different operations in a lathe using an H.S.S.  50 C34000, Free machining alloy steels (resulfurized), C33200, C34000, C34200, C35300, C35600, C36000, We have a drill speed chart for both metric and imperial drill bit sizes. speed chart. Check the electrical requirements for the before ordering. that cutting speed or surface speed would change with the size of the part. All rights reserved. softer the work material, the faster the recommended cutting speed (Figure 2). diameter part. the faster of the two settings if you are using coolant. Q & T, 150 to 175 275 to 325 Drill bit cutting speeds are very important in the drilling of metals.  70 N, Q & T LITTLELOCOS MODEL ENGINEERING is proud to present our HANDY LITTLE LATHE CHART, an outstanding timesaver for your shop.
