Modular Tombstone

Milling and finish machining of the steel and aluminium tombstones are completed with high precision machines using the highest quality tools available. This assure the highest accuracy possible and outstanding dimensional repeatability. All tombstones are quality controlled using a coordinate measuring machine.

The steel tombstones are manufactured from high resistance steel plate (50/55,5 kg.mm2 ). After welding, the steel is allowed a normalization period (800 degrees) in order to eliminate the inner stress. Afrer the milling and finish machining, the tombstones are painted and dried in an oven at 60 degrees.

The aluminium version tombstones are casted using the latest generation materials (AlCu4TiMGka) maintaining a high resistance (HB 90-115). After the milling and finish machining, the tombstones are anodized (type EN 12373/1 ex UNI 4522-66) in order to avoid the wear and tear of the surfaces.
