Is Your BIG-PLUS Tooling Underperforming? We Have the Solution.

Practical Machinist recently featured an article by Jack Burley, VP of sales and engineering at BIG KAISER, with contribution by Phil Marmo, SPS’s lead BIG-PLUS grinder, focusing on the BIG-PLUS spindle system and the main reasons why it may not be performing to the best of its abilities.

SPS Spindle Parts and Service is a licensed BIG-PLUS spindle grinder that can also perform onsite grinding. They’ve serviced hundreds of BIG-PLUS spindles and know as well as anyone the causes and solutions for the most common performance issues.

If you are wondering why this topic is important, BIG-PLUS is a platform used by about 150 different machine builders and 10 other toolmakers. Here are the main reasons outlined in the article that lead to poor performance:

  • Poor shop conditions
  • Automatic tool change misalignment
  • Using BIG-PLUS tools on an old machine
  • Using unlicensed dual-contact tooling

The article then digs deeper into the preventive measures to take to avoid BIG-PLUS underperformance. Burley and Marmo state that although in some cases it may be too late to take any preventative steps, having a certified service carry out a spindle regrind can return a BIG-PLUS spindle to peak performance.
