Customer Reviews for Dividing Head Indexing Head Milling BS-0-4inch/100MM for Milling Grinding

originally i needed a new chuck for my lathe so while shopping i came across the dividing head. my chuck would have been over 1/2 cost of entire dividing head. secondly first day here it was put to work dividing! works great nice piece for my retirement shop

I order this item under mini mill machine and it is not for a mini mill!!! It looks awesome! I will return it!

the product is as described and arrived on time, not used yet so I will update this review after use. First impression is good.

Fine

It seems ok for the money but all the movements were very gritty, after machining they just assembled without any cleaning or deburring then filled it with junk grease and hoped no one would notice, typical of Chinese equipment.EDIT: after deburr cleaning and better lube, it seems of good quality. Runout on the chuck is.003 acceptable but I plan to make it better. Notice the picture of backplate, almost half the surface for mating to the spindle was untouched when machining it. I raised it one star that’s being generous.

Perfect for my little hobby shop! I really appreciate the Great Value here! I certainly can't afford a name brand unit. I'm very happy with it. Thank you! Ron G.

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.

This dividing head has been fantastic. It is very durable and exceedingly accurate. It fights with my vise for space on the milling machine and often wins. There are so many projects that I can get done in far shorter time than I was able to before buying this. I am so grateful to have added this to my tool collection.

This unit went into a shop that supports both a museum and a low volume commercial small job shop, so I did not expect to be doing divider work very often. However, I have found it to be very versital and its low profile makes it easy to add to the BP table along side the mill vise. My only complaints are that the tilt feature does not have a shot pin at either the 90 or 0 degree position and the jaws are not soft-jaw compatible. The tilt issue means that the chuck needs to be dialed in whenever it is moved and that it can be knocked out of tram just under normal operation. The soft-jaw problem is not really fixable, its just nice to be able to use soft jaws for delicate work. Despite these minor issues, its a good value for the money and I can see that it will be a workhorse in my shop.

Product has very good quality. Great product at an even better price.
