Mark shows you everything you need to know to drill on a Haas lathe. Whether you have a standard 2-axis lathe, a dual-spindle lathe, or even a live-tool lathe, Mark simplifies the process, and explains all the G and M codes you’ll ever need.
Mark demonstrates how using a G53 command instead of G28 not only saves valuable cycle time, but also reduces the risk of crashing your machine. Mark walks you through both G-codes, and explains how and when to use each one.
Why move your turned parts to a mill for secondary operations when you can machine them complete on a Haas lathe with the BMT65 turret and live tooling? The BMT65 system provides increased cutting performance, longer tool life, and better tool clearance.
Setting Up Live Tools
Properly setting up live tools on a turning center can be tricky. Mark guides you through the process with a step-by-step tutorial that will answer all your questions.
