Product Series:Internal grinding series

Product Number:DGZM-08100QA

This product is a ball-type high-speed spindle for grinding machine,with the maximum speed up to 100,000rpm; it is mainly used for grinding andmachining of automotive high-precision component products such as fuel pump andfuel nozzle.

Designed with the advanced oil-gas lubrication method, this product canensure that bearing reaches the best lubrication effect through the accuratecontrol of oil amount and gas amount; moreover, compressed gas plays a functionof cooling and dust resistance against the bearing so that the service life ofthe spindle is greatly improved.

This product adopts the cooling method of “circulating water cooling +central water cooling”. Cooling water can forcibly remove the heat generated bythe bearing and machining so that it can effectively prohibit the temperaturerise of the spindle, reduce the thermal deformation of the spindle and achievebetter machining accuracy and surface roughness. The central water coolingmethod as the world’s leading non-contact sealing method, can extremely improvethe service life of the seal under the premise of ensuring the performance ofthe spindle seal.

Performance characteristics
1.
High precision: The run-out of the shaft end of the spindle for grindingand cutting in the inner hole is ≤0.001mm; the vibration of the spindle is≤1mm/s; it is characterized with unparallel high precision.
2.High configuration: It is equipped with the P2 bearings of internationalwell-known brands.
3.Circulating water cooling + central water cooling: Cooling water canforcibly remove the heat generated by the bearing and machining so that it caneffectively prohibit the temperature rise of the spindle, reduce the thermaldeformation of the spindle and achieve better machining accuracy and surfaceroughness. The central water cooling method as the world’s leading non-contactsealing method, can extremely improve the service life of the seal under the premiseof ensuring the performance of the spindle seal.
4.Strong compatibility and good expandability: The spindle for grindingand cutting has good compatibility, which has been successfully applied forgrinding machines of several international well-known brands.
5.Customization: The Company has powerful R&D strength to makeflexible designs, so that we can produce spindles for grinding machines withdifferent functions, speeds and accuracy according to customers’ needs.
6.Good seal: Designed with a structure of labyrinth seal + air curtainseal, it can effectively prevent cutting fluid and foreign matters fromintrusion during machining.
