美国采购需求：刀切机、切割服务器、模切机、激光切割机、数控切割机、IBright Cut

I am reaching out to explore ways to enhance the textile cutting capabilities of my machine, particularly for mattress zippered covers. I would like to know if there are any modifications available, such as knife replacements or belt upgrades, that could improve performance. Additionally, I'm in need of a quote for linear guide replacements. I've noted several numbers on the four guides I require, which may aid in identifying the right parts. I would appreciate any guidance you can provide regarding the necessary specifications and an estimate for the costs involved. Thanks!
