Haas explains the simplicity of the twin-spindle lathe for beginners

Added to MTDCNC by HAAS Automation on 26 August 2015

The twin spindle lathes from Haas are proving to be a popular choice among manufacturers that are aiming to reduce set-ups, improve productivity and ultimately make parts faster. Discussing the potential for the lathes, Haas engineers find the initial barrier for subcontract customers, is overcoming the advanced configuration and setting up the machines. 

For customers, the concerns often lie within the programming and the potential to move a part from one spindle to the next. When quizzed on the complexity and difficulty of moving from a single spindle turning centre to a twin spindle, Mr John Nelson, Director of Applications at Haas says: 'Its really a simple process. Looking into a Haas turning centre, we have a part set up in the main spindle and the B-axis in position ready to grab the part. All we have to do is start the spindles, provide a G-Code to synchronise the spindles. From here the chuck on the secondary spindle will open and come in to grab the part from the main spindle. The main spindle will release the part and the sub-spindle will retract with the part. We're already into machining operation two!'

With both spindles rotating, the process may look complex to new customers to dual spindle machines. However, the use of a single G-Code makes it extremely easy to conduct. Once the part is collected in the sub-spindle, the next concern for operators is how to program the part on the secondary spindle. This has also been simplified as Mr Nelson continues: 'Using the Haas control, we just have one code, G-14. Essentially what G-14 does is mirror the Z-axis motion and any spindle commands that have been given. This allows the customer to take a program written for a single spindle machine that may be broken into two operations and input them straight into the Haas control with just a G-14 code in-between. The machine will then take care of mirroring all the motion and operations on the second spindle.' 

With such a simple explanation, is there really anything holding you back from investigating the potential for a twin spindle machine?
