Stable and rigid spindle head
·The spindle runs on precision bearings, assuring maximum spindle stability. It guarantees outstanding grinding accuracy for external dia., internal dia. (optional) & end face.
·Rotation angle +90° ~ -30°.
·20 series spindle head adopts variable speed.
·32 & 42 series spindle head is servo motor driven with variable speed.
·Rotation angle +90° ~ -30°.
·20 series spindle head adopts variable speed.
·32 & 42 series spindle head is servo motor driven with variable speed.
Special hydrostatic bearing
The wheel spindle runs by using a special hydrostatic bearing and is especially ideal for precision grinding work. It features high speed, no friction between metals, no heat generation, deformation-free, extra high accuracy and continual use.
Precision wheel head
The grinding wheel spindle is made of SNCM-220 high grade alloy steel, which is normalised, tempered, carburized and sub-zero treated. The surface hardness reaches HRC62° and above. The surface hardness reaches above HRC62°, which guarantees no deformation, wear-resistant and high precision.
Various grinding application
·GU20x40NC Cylindrical Grinding Machine is capable of processing higher hardness materials, such as hardened steel, cemented carbide, etc.; it can also process brittle materials, such as glass and granite. The grinding machine can make high precision surface roughness very small grinding, also can carry out high efficiency grinding, such as powerful grinding.
·One grinder allows straight plunge grinding, shoulder grinding, traverse grinding, end face grinding, taper grinding & internal grinding (optional) functions for different machining purpose.
