Disconnect the lathe from power source, during maintenance, commissioning or repair. Failure to do so may cause serious injury. G E F Fig 11 GENERAL DESCRIPTION 1 Lathe Bed - the lathe bed (A, Fig. 12) is made of cast iron with low vibration and high rigidity. The bed integrates the headstock and drive unit, for attaching the lathe saddle and leadscrew and for guiding the lathe saddle and tailstock. B 2 Headstock - the headstock (B, Fig.12) houses the work spindle with bearing arrangement and the drive unit. The work spindle transmits the main movement during the turning process by gears. It also holds the workpieces by clamping device. The work spindle is driven by motor via pulleys. 3. Apron the apron (C, Fig. 13) is mounted to the carriage. Quick travel of the apron is accomplished by means of rack and pinion which is mounted on the bed, operated by a hand wheel on the apron. Automatic longitudinal feed is accomplished via the leadscrew also. A Fig Carriage the carriage (D, Fig. 14) contains the control elements for the different feeds and supports the apron. 5. Cross Slide - the cross slide (E, Fig.14) is mounted on the carriage and moves on a dovetailed slide which can be adjusted for play by means of the gib. 6. Top Slide the top slide (F, Fig.14) is mounted on the cross slide by T-screw which can be rotated 360 degree. The top slide moves on a dovetailed slide and has an adjusted gib, locking screw. Fig. 13 C E 7. Tool Post the tool post (G, Fig. 14) is located on a central pivot mounted on the top slide. It has four position click locator that locates it to its major axis. It can be held at any angle by the tool post locking clamp. D G F. Fig 12 8. Tailstock the tailstock (H, Fig. 15) can be locked at any location by a bolt. It has a heavy duty quill which can be moved forward or backward. It is used for centring and drilling, supporting long shafts, turning between centres as well as turning long, thin tapers. H 9. Leadscrew the leadscrew (I, Fig.

15) under the leadscrew cover through the various gear trains available rotates at selected ratio to the spindle to enable the various threads to be cut, or to provide a feed rate for the saddle when auto feed is selected. 10. Change Gears Box the box (J, Fig. 16) is mounted the side of headstcok. It is consists of pulleys and change gears. The rotation is transmitted through motor to spindle by pulleys and the feeds or threads are achieved with change gears and leadscrew. Open the lid case (K, Fig. 16) to make long workpieces! Fig. 15 I 11. Steady Rest the steady rest (L, Fig. 17) serves as a support for shafts on the free tailstock end. The steady rest is mounted on the bedway and secured from below with a bolt, nut and locking plate. The sliding fingers require continuous lubrication at the contact points with the workpiece to prevent them from premature wear. K 12. Follow Rest the follow rest (M, Fig. 17) is mounted on the saddle and follows the movement of the turning tool. Only two fingers are required as the place of the third is taken by the turning tool. The follow rest is used for turning operations on long, slender workpiece. It prevents the workpiece from flexing under the pressure of the cutting tool. Fig. 16 J L M Fig 13 OPERATION WARNING. Don t change the speed while the lathe is running. Failure to comply may cause serious damage to the lathe! B A 1. Headstock Gear Change Levers - located on front top portion of headstock. You can select six kinds of spindle speeds by moving levers (A, B, Fig.18) right or left. 2. Apron Controls the automatic longitudinal feed and thread cutting are achieved by engaging the lever (C, Fig. 19), push lever down to engage, pull lever up to disengage. The handwheel (D, Fig.19) is used to manually traverse the carriage. Fig. 18 G 3. Cross Slide Lever (E, Fig.19) cross slide is moved forward and backward manually with the lever. Rotate clockwise to forward and counter-clockwise to backward. F 4. Top Slide Levers (F, Fig.

19) located on the end of top slide. Rotate clockwise or counter-clockwise to move or position. Tool post clamping lever (G, Fig. 19) located on top of tool post. Rotate counter-clockwise to loosen and clockwise to tighten. Turning tapers with the top slide loosen the two nuts (H, Fig.19) to left and right of the top slide. You can then rotate the top slide. After setting the required position, tighten the top slide. H E D Fig. 19 C 5. Tailstock Controls the tailstock sleeve (H, Fig. 20) is used to hold the tools. The sleeve is clamped with the clamping levers (I, Fig.20), Rotate counter-clockwise to loosen and clockwise to tighten. Rotate the handwheel (G, Fig.20) clockwise to advance the sleeve and counter-clockwise to retract it. The tailstock on the lathe bed can be clamped with the locking nut (K, Fig.20). If the tailstock has a heavy load, tighten the nut at right side on the bed. Tailstock off-set adjustment two screws (L, Fig.20) located on the tailstock base are used to off-set the tailstock for cutting tapers. Loosening one screw while tightening the other will off-set the tailstock. H I K L G Fig 14 The locking nut must be loosened for this purpose. In order to avoid accidental extraction of the tailstock out of the lathe bed, a securing screw (M, Fig. 21) has been fitted at the end of the lathe bed. CAUTION! Check clamping of tailstock and sleeve respectively for tuning jobs between centers! M 6. Spindle Speed the label is attached to the hedadstcok. After a period of time some of the moving components may need to be adjusted due to wear. B 1. Gib Of The Top Slide loosen the nuts and readjust the screws (A, Fig.24) clockwise slightly. Then retighten the nuts. The top slide can be immobilised with the locking screw (B, Fig.24). A Fig Gib Of Cross Slide - loosen the nuts and readjust the screws (C, Fig.25) clockwise slightly. The cross slide can be immobilised with the locking screw (D, Fig.25) to prevent it moving axially during process. C 3.

Clamping Plate Of Carriage Two front clamp plate of carriage (E, Fig.25) are mounted on two side of carriage with four hex screws. Loosen the screws, dismount the clamping plate and regrind it. One back clamping plate are mounted on the carriage with four hex screws. Only through good care, you can be sure that the working quality of the machine will remain constant. Disconnect the machine plug from the mains supply whenever you carry out cleaning, maintenance or repair work! 2. Lubrication all slideways lightly before every use. The change gears and the leadscrew must also be lightly lubricated with lithium base grease. 3. During the operation, the chips which falls onto the sliding surface should be cleaned timely, and the inspection should be often made to prevent chips falling into the position between the machine tool saddle and lathe bed guide way. Asphalt felt should be cleaned at certain time. Do not remove the chips with your bare hands. There is a risk of cuts due to sharp-edged chips. 4. After the operation every day, eliminate all the chips and clean different part of the machine tool and apply machine tool oil to prevent rusting. 5. In order to maintain the machining accuracy, take care of the center, the surface of the machine tool for the chuck and the guide way and avoid mechanical damage and the wear due to improper guide. 6. If the damage is found, the maintenance should be done immediately.

I will in the near future up date my personal folio so then at least you can find out a bit about me. My reason for this post is to ask, if anybody can tell me if it is possible to install change gears on the BV20 Lathe.

I read a recent post that had a photo and discussion relating to a BV20 Lathe that had two(2) change gears fitted to the front of the Headstock. If I could source the change gears and levers maybe I could install them to my lathe. As it is If I want to change speed I have to get a spanner and change the drive gears. (Pain) Any information would be appreciated. Thanks My lathe BV20 has never had any change gears. Maybe when the lathes were sold here in Australia they were manufactured without the change gears. If I could source the gears and levers I am sure that it would not be a major job to fit them. The manual shows the same lathe. The only difference is my lathe has a maximum length of workpiece of 550mm. There is a shorter version of the BV20 that only takes a 400mm workpiece. Thank you for the links. Graham. Strange as it's a nice little Lathe as it was. My lathe BV20 has never had any change gears. If I could source the gears and levers I am sure that it would not be a major job to fit them.Which model do you have. Would you please point us to the Forum you mention in your original posting Eric My lathe BV20 has never had any change gears. If I could source the gears and levers I am sure that it would not be a major job to fit them.Would like to convert it to a change gear to give an easy selection for the chuck speed. I am not worried about the lead screw speed as that can be changed by the drive gears. I cannot remember where I saw the original setup but Omnimill has forwarded a link to the Manual for a gear change BV20M. Graham There is a Yahoo Group for the 9x20 lathe. They cover just about everything you'd want to know about your lathe. Regards, Rich My preference is for 180 volt DC motor and 230 volt AC to DC Convertor and Speed control. The DC advantage is that the Torque does not fall sharply as the speed decreases. My own setup is BV25BL lathe with six speed gearbox and DC motor and Control a very similar lathe to yours.

Normaly I select the gear for the diameter and approximate surface speed required and then fine tune the speed with the control. Being a DC motor fanatic my views are very biased with a lathe, milling machine on DC With power feeds on DC, Also two drill presses. Have a peek at my postings on HMEM Eric I think I will go with and research more info on what Eric has said. I will see what is available in Australia. Thanks to you all. Graham I am going to research the possibility of using a DC motor and electronic speed variation. Did you come up with a solution to the speed control.Unfortunately the guy who gave it did not have any manual to give me. I tried the provided link in the forum but it seems the file does not exist any more. Anyone who has the manual and is willing to share it. I need to check how to read how change speed of revolution. Thanks in advance. It is not much of a read but better than nothing. Let me know how you go. Hope this helps. Graham Mine is a Chinese model: BV-20 Bengbu Machine Tool Co. Also the photo of BV20-1 is not quite like mine. The reason I am looking for a manual is that I have no idea how to regulate lathe speed. I don't even know the revolving speed. The BV20-1 shows some levers above the start-stop buttons, which are not present in my lathe. It is not much of a read but better than nothing. Hope this helps. GrahamHelp needed.
