It shouldn't. Most of the structural HDPE is 20mm thick and the top, bottom and side plates are 10mm and held on rigidly. On top of that, there will be Hardox at the front to protect it all. I'd be very impressed if any spinner managed to get through all of that and shatter the inner HDPE structure!

The only time we've ever had any issue of HDPE cracking was one 4mm panel on Explosion when it fought NST, and even then it took a good few hits to do it. I can't really understand why often it is so brittle on other people's machines.
