Wał korbowy jest wykonany ze stali węglowej lub żeliwa sferoidalnego; jest to krytyczna obracająca się część silnika. Po zamontowaniu za pomocą korbowodu tłok przekształca liniowy ruch posuwisto-zwrotny w ruch obrotowy. Obecnie maksymalna prędkość obrotowa silnika samochodowego, którą znamy, może osiągnąć 6000 r / min powyżej, co stawia bardziej rygorystyczne wymagania dotyczące techniki procesu, w tym spójność lokalizacji, kolistość i prostoliniowość środka otworu w innym wale korbowym, chropowatość powierzchni itp.

 

End-face machining

FMA07 series face milling cutter, octagon insert with 16 cutting edges, combined with excellent “black diamond ”grade, can achieve super-high economical efficiency and working efficiency.

 

 

 

 

External turning

 

Insert edges has stepped appearance, external turning and step machining can be performed in one operation, greatly decrease the turning time and improve working efficiency.

 

 

 

 

Crankshaft external milling

        Teeth distribution in radial and axial direction can realize three side machining, more teeth involved in cutting, greatly improving the working stability and high efficiency.

 

Inclined oil hole machining

Convex milling: Solid carbide four flutes flattened endmill with straight shank, high stability edge treatment and high-rigidity structure design can realize multiple-functions of machining.

Inclined oil hole-making: combined with special coating grade, optimized structure design can achieve high-efficiency drilling machining.

 

 

Center countersink machining

ZTD series U drill, good mounting angle, optimized internal structure and firm drill

so the body can achieve high stable machining while bearing higher feed rate.

 

 

Flange hole-machining

Drilling: Solid carbide step drill, suitable for different high-precision drilling, can provide tailormade drills as per customer requirements.

Tapping:  Newly solid carbide taps and forming taps, according to different materials features, we design the products to meet different working conditions and machining requirements.
