Product Series: Dental Milling Spindle

Product Number:DGZ-03380/0.25A1-PG

This product is a high-speed ball motor spindle with a maximum speed of 80000 rpm. The spindle is designed with a long nose end. The spindle core and body conduction function (ESD) are optional, and it is sold with a low-voltage frequency converter.

1、Low temperature rise

The unique low-voltage motor design minimizes the heat generated, and plus forced circulation and efficient cooling, the dual technology significantly reduces the temperature rise of the spindle (2 ℃ lower than that of foreign competitors).


2、Low vibration

The integrated spindle core structure completely reduces the vibration of the spindle (at the highest speed, our vibration is ≤ 1.5mm/s, and the one of our competitors is 3.9mm/s), improving the stability of the shaft system, and reducing the abnormality of the spindle.


3、Reliable sealing:

the front end of the spindle is in a Frisbee structure, which effectively prevents chips from entering the spindle and contaminating the bearings, making it able to cope with complex and harsh working conditions.


4、High-performance frequency converter

The frequency converter adopts low-voltage drive technology, and its volume is 80% less than that of general-purpose frequency converters. It can be controlled in multiple ways. Thus, cost effective application schemes can be tailor made for our customers.
