  • Product Description
Product Introduction

Our company is the Ministry of Agriculture China Agricultural Development Group Corporation Zibo Diesel Engine Corporation 6170, 8170 crankshaft exclusive supporting manufacturers. With an annual output of 6170, 8170, 6190, 12V crankshaft 2000-3000 production lines, and external grinding 6170, 6190, 12V series crankshaft.

The crankshaft is the most important part of the engine. It bears the force transmitted by the connecting rod and converts it into torque to output through the crankshaft and drive other accessories on the engine to work. The crankshaft is subjected to the combined action of the centrifugal force of the rotating mass, the periodically changing gas inertial force and the reciprocating inertial force, so that the crankshaft is subjected to bending and torsion loads. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the surface of the journal needs to be wear-resistant, work evenly, and have good balance.

processing technology

Crankshaft rough machining will widely use advanced equipment such as CNC lathes, CNC internal milling machines, and CNC lathe broaching machines to perform CNC turning, internal milling, and turning-broaching processing on the main journal and connecting rod journal to effectively reduce the deformation of crankshaft machining. Crankshaft finishing will be widely used CNC-controlled crankshaft grinding machine for precision grinding of its journal.
