What spare parts should I require from a meat grinder supplier?

Start by listing blades, plates, shaft seals, bearings and whatever the maker flags as shortest-lived, then request a part number, fitted location and change interval for each. Rank them by downtime cost: anything that halts grinding is critical, the rest is routine consumable. Get recommended stock quantities written into the quotation, and ship critical items with the first machine so a sea-freight gap cannot stall you. On arrival, fit one set to verify plate-to-blade contact and leak-free sealing, then set your own min-max levels from that trial.
