  • Carrier Rebuilding and Repair

    The spindle carrier is the most substantial component in providing accuracy and holding tight tolerances with your multispindle screw machine, which is why extensive care and attention to detail is given to each and every one of our carrier rebuilds.  The entire rebuilding process is done in-house, including the grinding, which is done on our custom built Landis O.D. grinder set up exclusively for grinding carriers and tool slide stems.  We also have the capabilities required to re-bore your headstock (carrier housing) if needed as well.

    Our spindle carrier rebuilding and repair department offers quick turn around time to bring your Acme Gridley spindle carrier and tool slide back within OEM specifications.  Click on the carrier image to your left in order to review our spindle carrier and tool slide rebuilding procedures, and also to request a quote for rebuilding your spindle carrier and tool slide.

  • Custom Add On Kits

    Most all of our attachments, whether custom or standard, are able to be compiled into an "add-on-kit".  This in turn keeps costs low, and enables a more standardized and simple installation package.  One of our more popular packages is the Stock Depletion add on kit.  All of the electrical components are plugged in, with the only wiring necessary to install being a 6-wire cable to your existing main control cabinet.  Our Stock Depletion add-on kit also provides useful machine functionality, such as a "cycle stop" function, cycle time display, and resettable production counters.

    Another popular add-on kit is our Perishable Tool Counter.  This kit enables you to keep track of two tools per position, plus four auxiliary tools.  Not only does this kit save on tool changing costs, it also adds cycle time display, production counters, batch counters, daily and shift production counts, and more!
