I have been casually looking at Harrison Alpha 400 lathes (and Milltronics and Haas equivalent) but I am a little confused on the Harrison: I have seen a couple of 1998-1999, they have a Fanuc control with a small keyboard to the left. Then a 2000 with the same but also a larger keyboard to the right. HARRISON THE LATHE: T S Harrison & Sons was founded in 1898 and in the year 1900 built their first Harrison Lathe in Yorkshire, England. Harrison enjoys a long lathe history that spans over 110 years. To date there exists a North American Machine population of nearly 20,000 lathes and 140,000 machines throughout the world.

Manual Operation
May 17, 2019 Five easy sciatic nerve exercises include knee to shoulder, standing hamstring stretch, seated spinal twist, sitting pigeon, and forward pigeon. You can include these sciatica stretches in your daily routine to relieve your sciatica pain. Though medication can help alleviate the symptoms, exercise therapy that aims to stretch the sciatic nerve and surrounding muscles can also offer relief and can serve as a useful supplement to allopathic options. However, check with your doctor before doing these stretches, and use pain as your guide. If a stretch worsens the pain, don't do it. Exercise for sciatic nerve problems.
In manual operation the Alpha machine may be used in exactly the same way as a conventional manual center lathe fitted with a DRO. Any turner can operate this machine instantly.

Semi-Automatic Sequential Operation
Programmed sequential operations in simple question/answer page format at the machine mounted console for parallel turning, chamfer, radius, taper and multistart threads. Constant surface speed is a standard feature. Ideally suited for one-off and small batch production.
________________________________________________
Auto Cycle Operation (AlphaLink)
Complex profiles and threads are generated from the AlphaLink CAD/CAM (standard equipment) which can be written during machine operation and downloaded through the RS232 Port. The component is produced from automatic cycles and setting time is further reduced. One-off, small and medium batch production is fully utilized.
