In August 2016 we delivered sets of boring mill jaws to our Polish customers. These boring mill jaws are 300x180mm, i.e,. 300mm jaw base length and 180mm bolt holes distance. They have 2-piece top jaws which allow the operator to change the clamping ranges without having to move the jaw bases. Casting steel made jaw bases are rigid enough to support heavy workpieces and long-term heavy cuttings, and top jaws are made of alloy steel in a forging and whole quenched in order that the jaws have its internal hardness big enough to resist wearing out in a long time clamping job. 

For being suitable for clampings in both rough machining and fine machining, these boring mill jaws are supplied with a soft top jaw for each one. They are totally customized to meet our customer's special requirements. And of course on requests for any types & sizes of boring mill jaws which are needed to fit on a second-hand vertical boring mill or a heavy-duty horizontal lathe, we can present our proposals for customers' evaluations. Until now we have supplied many sets of custom made boring mill jaws to customers worldwide in various industries such as mining equipment manufacturing, nuclear equipment manufacturing, bearing manufacturing, valve manufacturing, etc.. Some of these boring mill jaws were large and used on 8000m vertical lathes, 120 Ton horizontal lathes.

We not only supply whole sets of boring mill jaws, but also pieces of top jaw blocks. In case top jaw blocks on the current boring mill jaws fail and are no use, we can manufacture new top jaw blocks to replace them. We always standby to serve your needs for boring mill jaws.
