How can you optimize the drilling cycle without compromising processing safety? Which processing strategy will shorten the cutting cycle to an important one or two seconds? These are the main challenges facing the automotive industry.

How to deal with these challenges, but also from the automotive industry drilling and thread processing process features. In general, the materials used in the automotive industry are conventional, mainly cast iron, aluminum, cast steel and forgings. But the workpiece structure is extremely complex, and its required production efficiency, tolerance and surface quality are also very challenging.

The shallow hole, deep hole and tapping solution of the Sandvik Coromant is designed to provide a range of special threads for specific types of holes and key components such as engine blocks, cylinder heads, housings, and crankshafts. Key tool.

Resolving crankshaft machining problems: CoroDrill® 865 crankshaft oil hole drilling

CoroDrill® 865 provides an efficient solution for the common expansion of automotive cast iron parts and steel parts, especially crankshafts, when applying special centering drills. CoroDrill® 865 features, such as reduced vertex angle (more accurate centering), optimized rear and front angle features (feeds are higher, chip removal is smoother), increased blade width (stability Better), updated the spiral groove type (chip forming more effective, higher tool strength), so that production efficiency and tool life has been greatly improved. The use of effective processing strategies, coupled with well-controlled coolant or MQL, is the key to ensuring success.

 Deep hole applications can achieve high production efficiency and long tool life

 Optimize the base material for ISO-K and ISO-P parts

Extremely excellent processing safety

 diameter range: 3-10 mm (0.118-0.394 inches)

 Drilling depth: up to 25 times the diameter

 achievable hole tolerance is H8
