Thisproduct is a directly-connected spindle for machine, with the maximum speed of8,000rpm; the shank type connected with the spindle is BT40. It is used in themachining center for milling, cutting, drilling and tapping.
1.Highprecision: The yaw of the core taper hole is ≤0.002mm/s; the run-out at the300mm position of the standard rod is ≤0.008; the dynamic balancing grade isG0.4; so it is characterized with unparallel high precision
2.Highconfiguration: With the bearing of an international well-known brand and partsof high standards, it can ensure the long-term stability and reliability of thespindle. The spindle is aligned with the drive motor through a coupling toachieve synchronous transmission.
3.Lownoise: Under the same operational conditions, its noise at the maximum speed isabout 5DB lower than that of the straight type coupling of national standard.It can provide clients with better machining performance and healthy workingenvironment.
4.Diversityof shanks: Shank interface types such as ISO, BT, HSK, etc. can meet differentapplication needs of customers.
5.Highstability: Designed with unique and stable cutter release mechanism with anultra long service life (≥2 million times), it can ensure the long service lifeof consumables.
6.Uniquedesign: Thanks to the design of air curtain seal +labyrinth seal, it canrevolutionarily improve the sealing effect of the spindle and effectivelyprevent cutting fluid and foreign matters from entering so that the spindle canalso be operated normally under poor conditions. Therefore, it can reduce thefaults of the machine due to seal problems, thus improving the efficiency forthe customer.
7.Thefront end of the spindle is equipped with the cutter cooling ring spray system.For the ring spray, the angle of the cooling nozzle can be freely adjustedaccording to different parts or cutter cooling requirements. The spring spraymay be at the end surface of spindle nose, where it is closer to the requiredcooling position so that better effect of cooling and chip removal can beachieved.
8.Withthe drive motor, it can generate a large torque at a low speed and a big power ata high speed.
