Mini Lathe

thingiverse

This is my Ver. 2.0 Four axis X0 and X1 for table and drill tool, Y and Z for tool holder. Rotatable table(every 15 degrees). 0,1 mm precision for X0, X1 and Y. With linear bearings for X0, X1 and Y. I ll make updates regularly. Motor part will be for some el. drill at first or may be for permanent, will see (it is not ready yet). Probably I ll change things on Z. All parts are printed with my homemade 3d printer. PLA 0.2 layer, 0.3 mm nozzle 25-30% infill. 0,1 mm layer for rulers and arrows. Used support only for 002_Arrow_4_X1_line.stl. Parts 030_ToolHolderP3_ABS.stl and 031_ToolHolderP4_ABS.stl will print with ABS for better grip. 12.08.2015 Printed the 2 ABS parts and made M4 nut holder(032 number part - for tool holder)/see last Autocad picture/. Reuploaded 023_TableBaseP3Left.stl - there was missing bed for X0 arrow. Needed things for assembly of Base, Drill tool and Table here: http://www.trendi3dprojects.net/lathe2_2.html 16.08.2015 After assembly of all Tool Holder parts, I saw a lot of instability and weakness. So parts 25, 26, 29 and 30 were reworked and reuploaded. Also added part 33. Needed things for assembly of reworked Tool Holder here: http://www.trendi3dprojects.net/lathe2_3.html Now it looks a lot better, but there is some backlash from LM6UU bearings... and none from LM8UUs. 17.08.2015 So, the backlash (axial along on the 6 mm smooth rods) with the tool holder is serious and part 27 will be reworked for 4 pieces of LM6UU bearings(instead of two). If this does not improve the situation, I `ll remake it for LM8UU bearings. 19.08.2015 Part 27 for tool holder remaked and reuploaded. It is now for 4 LM6UU bearings for better stability. Extra 2 x M3 nuts and 2 x M3x12 mm bolts are needed for assembly of this part of the lathe. Reuploaded Autocad pictures with current updates. Added Autocad (Ver. 2010 or higher) file for laser cutting of heatshield of table - if the thing can manage, when ready, with soft metals - Aluminium, Copper, Brass. Added part # 36 - 25 mm spacer for the wheel on X0 axis - it is still not very comfortable for rotation, but it is better than without it. Needed things for assembly of movement rods and wheels: http://www.trendi3dprojects.net/lathe2_4.html 21.08.2015 Added parts #34 and #35 - front clamp for el. drill. It is universal for all drills with 42-42,5 mm radius behind the drill holder. Back clamp is another story. It is hard to measure and make, and it is individual for the drill, because of its shape. I ll upload the one for mine Black and Decker CD501 drill, when it is complete. So far first atempt was unsuccessful... But I still manage to use it, after a lot of filing... Added parts #37 and #38 - back drill clamp. !!! It is individual for every drill. 99,9% it won`t be usefull for You. You have to make your own back clamp: http://www.trendi3dprojects.net/lathe2_5.html So, thing is completed at 99 %. Heatshield for table - next month (got a lot of stuff for laser cutting and lack of money is putting me on stand by). Tests - next week. Then I`ll share my Autocad drafts, so You can change, remake, etc. 24.08.2015 Updated with this thing: http://www.thingiverse.com/thing:624625 25.08.2015 Video with tests of wood, plastic, aluminium, steel, stainless steel - https://www.youtube.com/watch?v=4tGpBWL564o Results are a little bit disappointing. Have in mind, that I am with 3 LM6UU bearings(not 4), so there is still a lot of wobble and instability in Y/Z. I have ordered some, but they won`t arive soon. No such bearings here (just 8 mm or above). Also got a 1 mm mistakes in arms #2 (here they are fine), so now I am printing them again. One other thing - el. drill is not very suitable as motor, bacause ot its hammer mode, relatively to that - axial movement of its drill holder. So after fixing these issues I will give it second chanse. If results are similar it will be left for wood and plastic and will use it as base for next one in the future. Uploaded drafts for Autocad 2010 or higher version.
