Нужны стальные каленые ровные валы диаметром 5мм и длиной от 100мм, без лысок. Покупал на ебее 5х200 HSS, в первый раз прислали нормальные, а во второй - аццки кривые, около миллиметра прогиб в середине (продавец и товар те же). Может кто-нибудь знает надежный магазин?
Толкатели для прессформ поищите в Питере. Наверняка, фирмы которые продают комплектующие, 5-ки имеют на складе.
В Москве я например иногда брал необходимые мне размеры тут
Пятку отрезаете болгаркой, нужный размер на наждаке.
У обычных поверхностная закалка до 60-64 HRc. Допуск по диаметру как правило -0.01 мм.
