New guy here. I have a oilfield service company and bought a little 1236 Matthews lathe. Usually working with 4140 & 4145 material. Basically just turning and boring. I have very little knowledge when it comes to machining, but would like to learn. I need to buy some new inserts but have literally been online for 3 hours and still dont know anymore than when i started looking. I know that the inserts that came with the machine are CCMT & CCGT. Could someone please point me in the right direction on what to look for. Any help is much appreciated.
