Our new product SinterGrip is born to satisfy the current need to clamp a workpiece for very few millimeters (with SinterGrip 3,5 mm clamping surface), and this for the following reasons:
1) In order to machine the workpiece completely in a single operation (especially for 5 axis machines);
2) In order to save money for the raw materials, especially when they have a big impact on the price (aluminum, titanium, etc.)

Indirectly to these reasons, and in order to improve the performance of the machine tool and the tools

higher cutting speed + higher feed rate
= bigger volume of metal removed
= less time to machine the workpiece

The market requires safe clamping, which could at the same time possibly avoid the deformations of the piece itself.

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.

STEEL
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

ALUMINIUM
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.

CAST IRON
Type UNI EN 1561 GJL - normalized at 500/550°C - High resistance HB 180-220
