Equipped with the ACU-RITE® 300S DRO with Thread Assist Cycle... Cut Metric Threads as Fast and Easy as Inch Threads on Clausing Lathes with an 'Inch' Leadscrew Cutting metric threads on a lathe with an 'inch' leadscrew is difficult and time consuming, requiring a more experienced operator... Cutting metric threads on Clausing Standard Lathes equipped with an Encoder and the ACU-RITE® 300S DRO with the Thread Cycle is as easy as cutting inch threads, just follow a few steps and you’re ready to go

The Advantage of Clausing Standard Lathes with Thread Assist... When cutting metric threads on an 'inch' leadscrew machine, the half nuts must remain engaged during the thread cutting sequence. This is because the standard 'inch' thread dial indicator can-not track the exact lead of a metric thread. The machinist must either reverse the spindle direction, or reverse the leadscrew on headstock (on Clausing/Colchester Lathes) in order to bring the threading tool back to the start position. This is a very awkward and somewhat confusing procedure as it requires more functions for the machinist to...

Use down arrow again to FINISH, in the highlighted area input the depth of the finish pass. This is the 6th and final pass. Step 3: Executing the Thread Cycle The P:1/6 indicates what pass you are executing, in this demo you have 6 passes, 5 normal passes and 1 finish pass. At this point you will start move X & Z axes to zero Handwheel, move cursor a' between markers '£>'. Notice cursor 'e' will start to move from right to left when the spindle is engaged. Heady to Eng»fle Thread Uvnr On the first pass only, you will engage the Half Nut (Thread Lever) either by using the thread dial on machine...
