Reseñas de clientes para VEVOR Mandril de Torno de 3 Mordazas Diámetro Exterior de 160 mm Autocentrante con Placa de Soporte Roscada, Rango de Sujeción de 3-145 mm con Tornillos de Llave en T para Torno de Madera y Metal

tutto ok come descrizione grazie

Sehr preiswertes Futter, robust und gut verarbeitet. Den Camlockflansch kann ich nicht bewerten, habe einen Flansch für meine Maschine gedreht. Die originale Rundlaufgenauigkeit ist für diesen Preis ok (0,07mm gemessen mit Feintaster), durch Nachbearbeitung der Futterrückseite konnte ich das noch etwas verbessern. War ein guter und nützlicher Kauf, kann ich empfehlen.

This chuck was stiff on arrival from leftover machining dust. I disassembled it (easy to do), cleaned all the parts, and reassembled with super lube. The unit is now nice and smooth. Accuracy with a 1/2 in pin gauge chucked is around .001", which is in the same ballpark as the lathe spindle (12x35 Grizzly), so hard to fault the chuck for this application. It was best at one location, so I put timing marks on that position. The unit has a nice range with bolt-on reversible jaws, so very handy for grabbing tubing or other hollow objects.

Came in with smashed box and had been retaped, problem with the shipper not Vevor. Bolts for backing plate were missing, once again I believe because of the broken box. Chuck itself seems to be fairly well made and heavy, jaws are a good fit. Very gritty so had to take apart and clean before use. Mounted and tried it, and T.I.R. was .0075". Set it up and did a minor grind to the jaws and have it to .002" T.I.R. Will run it for a while to loosten it up and then final grind it. I have had to do this with others too. Seems pretty common. All in all it seems pretty good. Backplate runout on face was about .0002" and outside was .0001", very good.

Aguasta uso constante sin problemas.

well made, a few nicks needed to be stoned out. would have been nice if the back plate bolt holes were counter sunk.

Bonne qualité du produit point faible mauvais ajustement des tripodes et manque de graisse

I am an amateur, home shop machinist. I bought this chuck with the back plate and shipping included for less than $125.00, an outstanding value IMHO. The two-piece jaw configuration was a requirement and the source of some problems that may or may not affect your decision to purchase this chuck. If you purchase this chuck, be prepared to disassemble it and thoroughly clean and lubricate it. This one was FILTHY, but I expected it would be. After cleaning, a precision 0.5000 pin ran within 0.0020" TIR. , well within spec. I trued the back plate mounted on my lathe spindle (70-year-old South Bend 9-A) and turned the register boss to 0.0050" smaller than the register recess in the chuck body. The test pin repeats within 0.00050 after assembly and adjustment. Amazing IMHO! I removed the top jaws and cleaned the interfaces with the jaw base. Upon reassembly, I could not get the chuck adjusted any better than 0.015" TIR. I reground the key slot so the top jaws would actually seat properly. I will regrind the jaw faces under clamping load with a tool post grinder when I get time. In the meantime, I'm using machinable steel top jaws to hold some 2" diameter steel discs for turning, facing and boring on both faces. The chuck repeats within 0.00050" TIR with this configuration. Again, amazing. I would purchase this item again but only if I had time to do the aforementioned rework.

Very good tool, runout was only .002 thousandth installed out of box. Very good for what I use it for. Neighbor bought a 4 inch to expand centrifugal clutches , I had to machine jaws thinner for unique tool use. The 4 inch was so nice it caught my attention so I ordered a 6 inch to put on one of my small lathes.

Muy buen tiempo de entrega
