Product Features

In the processing of automobile engine cylinder block cylinder head parts, milling processing is mainly reflected in the  following aspects:
Time-consuming, great impact on the production line;

The consumption ratio of the blade is large;

Surface can be used as the positioning benchmark between processes, which has a great impact on the quality of the final product;

The surface is also the assembly standard, and its surface quality directly affects the assembly accuracy and performance of the engine.

 

Aluminum alloy material processing

The PCD blade is directly welded to the tool holder, and the axial runout of each tool tip can be accurately adjusted through the adjusting mechanism on the tool holder. The cutter holder adopts radial screw locking on the cutter head, which takes up little space, can realize the design of dense teeth and improve the processing efficiency. The blade mounting groove is designed as dovetail groove structure, and the blade will not fly out even if the locking screw is damaged under the condition of high speed machining, so as to ensure the safety of personnel and equipment.

Processing case

Aluminum alloy cylinder head joint surface finishing milling cutter head: Φ220 mm (Z=22) inserts: PCD inserts  

processing parameters: VC = 2800 m/min; N= 4050 r/min; Fz/r = 0.08 mm; F=7130 mm/min

longevity: 12000-16000 PCS

 

Cast iron processing

Each tip can be precisely adjusted axial length to ensure good end tooth runout. The whole cutting edge of the trimming blade is designed into a very large circular arc, which can obtain good flatness and surface finish even under the condition of high feed of large diameter cutter head. The blade has cemented carbide and CBN two kinds of material, according to their own production program and cost requirements to choose their own blade.
