Virtually all lead screw tappers and drilling units can be outfitted with adjustable or fixed center multiple spindle heads. A thorough analysis of your application will reveal if these types of multiple spindle drilling or tapping heads are warranted.
JS Tooling is always my go-to for any components I need for my equipment. Definitely recommend them.
I needed several customized machines to optimize my production, and JSTooling was able to help design and create everything I needed.
Nothing but great experiences with these guys. Highly recommend.
Hands down the best I've ever worked with.
