Big Plus Spindle Repair

BigPlus® is a patented spindle system that provides dual contact between the spindle face and the flange face of BIG-Plus® tooling. Simply by switching holders, you can greatly increase tool rigidity, reduce runout and add significant productivity to your machining applications. BIG-Plus® holders and spindles are manufactured to micron level specifications.

This means a BigPlus® spindle repair needs to hold the same micron level specifications as the tool holders themselves. The repair of a BIG-Plus® taper can only be done by trained personnel using BIG-Plus® certified test equipment. Northland Tool has made the investment in this tooling to ensure our customers are receiving the maximum benefit from their investment in BIG-Plus®.
There is a Good Chance Your Spindle is already BigPlus®. If it is not Northland Tool can help determine if your spindle can be converted to use BigPlus® tooling. The spindle design dictates this but we have been successful in converting several types of spindles to have BIG-Plus® capabilities. 

Other spindle repair companies claim they can repair BigPlus® spindles, but to function properly, the precision in the remanufacturing of the tool interface must be absolute - requiring extremely advanced, temperature controlled processes with BIG-Plus® certified test equipment. If not done properly spindle and tooling damage may occur.
