1. Features of Crankshaft Grinder: High precision, high rigidity, high efficiency, mass production stability
Used in aviation, medical, hydraulic, mold, high-end automobile manufacturing, robot reducer and other industries of camshaft, crankshaft and drive shaft, eccentric shaft type workpiece precision grinding, and can achieve a clamping, grinding two eccentric shaft outside diameter and multi-eccentric outside diameter.
The use of advanced numerical control system, the manipulator to achieve automatic clamping, further high efficiency, shorten the production rhythm, but also to avoid the accuracy error of human tooling.
2. High rigidity bed
Bed design:
Integral cast iron bed structure,With excellent heat dissipation and vibration absorption ability, maximize the accuracy of the machine tool retention. Suitable for complex environmental requirements in mass production.
Bed part:
The wheel head frame, workpiece head frame, spindle and all bearing support elements are made of high-grade cast iron or steel material, ensuring a homogeneous, continuous and stable coefficient of thermal expansion between the machine bed and components. Thus providing a more stable working environment
Rapid hollow drainage structure design:
● Unique drainage structure, the grinding area of the body
● work surface is designed with inclined surface and hollow
● drainage structure to form a drainage channel, and the oil sewage slag flows into the embedded
● drainage tank along the drainage outlet, making full use of the internal cavity, so that the grinding coolant is discharged in time
