Hello Please suggest for below. 1. Whether less than 1 Ra surface finish is possible with 10 d boring bar AV -D40-10 D-C. 2. Material is Steel with hard ness 27-29 HRC. 3. Suggest nose radius to be used 04 or 08 ( cxmg 12). 4. How to adjust the centre height . Pl share details with animation. Thanks
To achieve the desired result the required surface quality can be performed on steel in accordance with ISCAR's technical recommendations. ISCAR's recommends to machine with a 0.4mm radius insert based on 2 options which enable adjusting the center height as shown in the links below: ua-cam.com/video/RPnJatXEPhs/v-deo.html ua-cam.com/video/60683scwShA/v-deo.html
these are all silly questions. ask the machinists who are going to make the parts for you. too little info to give an answer. but generally achieving that surface finish is up to many things other than the boring tool. material hardness doesnt determine surface finish. you can get get the same Ra value with a bigger nose radius by having a low enough Feed/rev. center height is determined when you insert the tool holder, or digitally by offsetting the Y-axis.
