5Inch 3 Jaw Chuck Dividing Head Set Precision Semi Universal Dividing Head for Milling Machine Rotary Table Tailstock Milling Set

I recently purchased a Vevor BS 0 Dividing head and I would like to do a review. Quick take -A good buy for about $220 ( with tax). The main body is well made, but the additional work that would make this a $500+ unit are left to the buyer but are easily done. Out of the Box - all parts were present, although one of them should have been scrapped. A carrier had been double drilled and broke out the side. My options with Amazon were to return the unit entirely or contact the manufacturer. I contacted Vevor and received a request for a picture of the damaged part within 24 hours. I sent them a picture and I received an immediate answer that they would send me a replacement. EDIT: The part arrived and is in good shape All of the parts needed deburring, A total of about 30 minutes to knock off sharp edges. All of the machining looked good. The tail stock is fine, the dead center was clearly heat treated, but not polished afterward. Some of the bolts are a bit rough - again a touch with a file. The dividing head is impressive in weight, very solid. The index marks are very clear. I tore it down because various YouTube videos said there might be debris inside. There was some, and it was worth doing. I've greased and lubed it. I deburred and stoned the dovetails and it is much smoother. I got the chuck off, it is quite tight, but finally unscrewed ( check You tube videos). I felt that the thrust bearings were too tight, making it very difficult to rotate the spindle. I adjusted them to my satisfaction and checked the runout. Using the provided dead center it was about .0025, but when I used one of mine it was about .0005, quite nice. The three jaw chuck had about .003 runout which I think is ok for a 3 jaw. When I put on the direct index plate, I rotated it so that the 0 mark was on top, and reset the index mark. The indirect plates seem to be fine, but the right and left index arms would slip badly, a very bad thing for a dividing head! I used a file on the back of the arms to remove the residue of sprues left after manufacture. I then sanded the back till it was flat, also filed/sanded the round portion of the arms, until they were flat. They now are quite secure. Hope this helps anyone trying to make a decision.

The Vevor Dividing Head Set is offered at a Great Price. I have had Success with Vevor Tools in the past so I went for the BS-0 Package for my Mill. The Dividing Head arrived, Securely Packaged with no Damage. All of the Accessories were in a Nicely protected Styrofoam & a Heavy Duty Box. There were Steel Chips and other Debris on the Outside of Almost Everything, Cleaning the Outside of the Tool & Deburring All Three of the Dividing Plates is a Must! I Did Not Disassemble the Headstock, The Rotary Action & Tilt Feature is Smooth & Extremely Accurate. I am very Happy with the New Addition to our Shop. We Also use our 4 Jaw Chuck when needed, Adding More Versatility to the Dividing Head. Vevor has Always Had a Good Reputation of Honoring their Warranties, I Hope They Follow-up with their Suppliers, Overall Cleaning The Tool Took Very Little Time, Including Deburring the Indexing Plates. In All Honestly, This is a Very Nice Dividing Head -> Well Worth Every Dime.

I've spent two days cleaning, deburring and adjusting this thing. Depending on how valuable your time is, or if you actually have to make money with this, it may not be for you. I'm retired and equipping a hobby machine shop, so making this into a useful tool is interesting and educational for me. The quality of machining is generally good, but QC is virtually nonexistent. I completely tore it down and cleaned out all the factory grease, which left me with a pan full of grinding grit (but very few metal shavings). I'm stoning surfaces and deburring and chamfering sharp edges as I reassemble the head, and oiling and greasing where appropriate. Some of the screws are very poor quality, so I will be replacing them. The engraving on the fixed indexing plate is off by a full degree at 180, but at least the holes appear to be reasonably accurate. The ball on the end of the worm shaft was so soft it had already developed a flat spot, so I'll be replacing it with a hardened bearing ball. I added a washer to the eccentric clamping screw, making it quite a bit easier to adjust the worm. The included chuck was a Sandu (reject?). The logo was partially ground off, and it had a runout of 0.009" with a 1/2" rod chucked in it. It was also full of grinding grit and operates much more smoothly when cleaned and re-greased. My excellent 1946 Logan lathe has a 1-1/2 x 8 spindle nose, so I installed the chuck and re-ground the jaws, but the best runout I could get was still 0.003". Not exactly horrible for a cheap 3-jaw, but not great either. P.S. The "spring" that tensions the sectors against the indexing plate is a joke. I bought some bowed side-mount external retaining rings (98398A155) from McMaster-Carr and deepened the groove on the worm shaft to 0.675" (about 0.02"). With it snapped in the sectors are properly tensioned against the plate and feel like they should. I also replaced the cheap screws holding the indexing plates with some good black oxide flathead allen screws (also from McMaster). I had to chase the badly tapered threads in the spindle nose cap too, to get it to even thread on. Like the title says, it's a kit, but the only thing that couldn't be fixed was the distorted degree markings etched on the front plate that are out a full degree at 180.

This dividing head is not a bad deal for the price point when compared to other brands in this size range. The accuracy of this is OK for the hobbyist that is not working within very tight tolerances, it is out of tolerance 1 degree in it's 360 degree rotation. When received it is highly recommended that it be disassembled and CLEANED! The worm gear for the head rotation is very sticky and has what appears to grit/fine sand/lapping compound mixed with the grease ... not sure for the reason of this?! The rotation pin/locating handle was stuck and somewhat rusty inside and had to be disassembled and cleaned to make functional. The manual that comes with this is mostly worthless with the exception of the indexing charts in the back! With this being said it is not a bad tool for the cost and will make a very good cost effective tool for someone that is desiring to learn how to use this type of tool without the cost of one that is three times the price.

This is a very nice dividing head for the money. Pretty well finished and smooth operating, very little lash in the gearing. If you were thinking to use an ER32 chuck in the headstock taper note that the taper is #2 Morse not #7B&S as stated in the specifications. That is really good news given that the ER32 chuck adapter for #2 Morse is much cheaper than the #7 B&S. They are also available with 10mm drawbar threads so you can eliminate the chance of slipping in the taper. I checked the run-out specifications and found the following: Radial run-out of the spindle nose spec 0.0006" Actual <0.0002" Radial run-out of spindle taper nose spec 0.0008" Actual was about 0.001" Radial run-out of spindle taper hole 4" distant 0.0014" Actual was 0.0025" Radial run-out of test bar with 3-jaw chuck 0.0031" Actual was 0.003" So the specs were pretty close and my measurements might not be perfect. The run-out with the 3-jaw chuck was due the the chuck back-plate (spindle nose locating diameter had <0.0002 TIR). The locating diameter for the chuck had a run-out of 0.0025". That could be corrected by taking a few thousandths off the locating diameter, center the chuck and use the mounting screws to lock it in.

I haven't actually used this for anything yet. I did however disassemble and check everything. Initial run-out was 7-10 thousandths and I was disappointed. I then installed the dead center and checked run-out and it was .0005 in. OK. that is great! I then re-installed the chuck and chucked in some ground drill rod and now run-out is .00025 in. WOW! Backlash is adjustable and was nearly perfect. The index plates look accurate so dividing should be accurate as well. I couldn't be happier with the value and the quality far exceeds my expectations. I was surprised there is no lock on the face plate to the spindle, not having used an dividing head before, I have no idea if this is normal. so while it's is possible to drive this up to 2400 rpm (its in the manual) there is no lock to keep the chuck on the face plate so turning something in reverse could unscrew the chuck. I'm not driving it so I don't care. I've paid nearly the same price for my MT-2 JT3 Jacobs chuck (super ball bearing chuck and arbor) for my drill and it has more run-out than this table.

Sometimes you have to make a purchase for a project you’ve been putting off. After some research I went with this. Works as it should. Now I wish I purchased sooner. Just note it will need some cleaning and adjustments.

I knew by watching videos about this dividing head it would need a bit of work, but not this much. Maybe if you buy it from the Vevor website it would be better and they just dump the rejects on Amazon. Screws in the wrong locations, fit issues where if you tighten the backlash adjuster too tight nothing moves. Sector arms would barely move. The locking mechanism, the bronze colored wedges are just that, Bronze colored, made out of steel. If I didn't already disassemble and start to clean and re-machine everything I'd send it back.

Buen producto práctico y a buen precio

It is of good quality, for home use its a bit big , but I would be lost without it,

Very well built, smooth operation, fast delivery, but have yet to put it through it’s paces.

The order arrived early, , "great" , chuck key was missing and so were the reverse jaws for the chuck "NOT SO GREAT" not sure how to get this rectified other than this review. I cannot find an avenue to contact anyone. The locking handle for the main spindle is mild steel with an M6 thread (wont last long) I replaced it with an 8.8 grade bolt and sleeve. The rest of the unit is fine for the purpose mechanism seems smooth enough. If all the parts were there It would not have been worth the commet

It looks fine under the three plates I got two of them same plates
