Either that, or put in a switch with a lower psi setting. I guess this means "Atmospheres", so 45-75 psi. Graziano told me the lower gearbox pressure should be 3-5 ATM. If it gets to be a problem, I think I would by-pass the switch and put a pressure gauge in the system, one that can be viewed from out side. There is a timer in the sytem that allows the motor to start and get up pressure. There is a oil pressure switch on the lower oil pump, if pressure drops it cuts the motor. One problem you may have - The lathe starts OK, but after a minute, the motor cuts out. Looks like the four bolts are all that holds the gearbox in.
#Graziano sag 14 manual#
My manual only shows parts, no instructions at all except for lubrication. Note, in the lower gearbox, the oil pump sticks out, you will see it when you open the door, it has a filter behind the screwed-in bung. When the spindle is started there is a whining noise from the gearbox, not too loud.
My lathe, when idling, makes some noise, the motor is turning the input shaft of the gearbox all the time. Lots of stuff in there, needle bearings, clutch packs etc. Down for reverse.ĭon't be in a hurry to dismantle unless you are pretty happy with such a job ie bearings pressed onto shafts, need for absolute cleanliness etc. Now, where was I? A manual, I've got one, if you can't find something closer to home, let me know.Ĭheck out Tony for interesting Graziano stuff.Ĭheck to see you have the motor turning in the right direction, when you lift the hand control, the spindle should rotate in the normal direction.
(Note, Graziano later made a Sag 12'S' with Reeves drive, maybe the electric change gearbox of the Sag 12 was too expensive to build)? The headstock has its own oil pump keeping the Gamet bearings happy, and the main speed change gearbox is seperate, it has its own oil pump too.Īnother good idea, it has holes in the bed casting that allow you to stick a length of round steel through at each end of the lathe, and so sling the lathe easily without doing any damage. I took my carriage to bits for a look - what a beauty! Fine engineering throughout. The tailstock ways stop well short of the spindle, so you have a natural gap-bed effect - a lathe which swings 6" over the crosslide can also swing 17" in the permanent 'gap'. This means the main ways can be well covered from above. This is because the tailstock has its own ways, they are a lot higher than the carriage ways. Well, the vee ways are covered, so no chips can get to them. And another two magnetic clutches for forward and reverse. By switching off one clutch and switching on another you get instant on-the-fly speed change. This is because the gearbox has four magnetic clutches, each attached to a constant-mesh gear. In the space of a second you can change speed four times, and change direction too if you want. Speed change is instant, just a little twist, and it immeadiately jumps to the speed you've clicked to. We suggest an inspection on site.In my possibly biased opinion, a very good lathe, fun to use and well designed and built.īecause spindle speed, direction and on/off are all controlled by one 'joy stick' on the right hand of the saddle. Please read the tender notice and the attached lot. 39 will be required to send, within and no later than 48 hours after the auction close, to the address the documents indicated in the tender regulations.
