Features of single part
M2-AM low speed dental handpiece motor
The low speed dental handpiece with internal water spray features flexible and convenient operation.
Compared with the external water spray, the internal water spray has no water pipe connection on the handpiece motor. The water passes directly through the inner of the motor. Thus, it can realize 360 degree rotation of the motor at the same time. It features better maneuverability.
M2-SH low speed straight handpiece, dental drill
The low speed straight handpiece has the additional water spraying function which can reduce the dust caused by grinding during operation, thus protecting the doctors and patients from being hurt by the dust.
The jitter frequency of the handpiece is quite small. The testing results shows that the radial run-out is less than 0.03mm which is more suitable for various fine operation. This handpiece can be more convenient.
M2-CA low speed contra angle handpiece, dental drill
The water spraying hole of the low speed contra angle handpiece is fixed at the front end of the machine, thus reducing the steps of installing external water pipe and snap joint. The water spraying is more accurate as well.
The M2 dental drill adopts push type bur change which is the replacement of the original difficult clamped bur change. This method features quicker, more convenient and time saving bur assemble and disassemble, thus saving every minute for doctors. It also avoids the medical safety accident caused by bur looseness because of lacking of clamping force.
Equipment set features
The dental polishing ring of M2 low speed handpiece with internal water spray is made of material from America which is treated by many steps of process. It will not be damaged after disinfection with maximally 135 degree high temperature and high pressure steam.
This dental drill adopts ceramic bearing, imported ceramic ball, cage which is made of material from UK. The two side of the bearing is equipped with sealing device which can protect the internal of the bearing from external dust and some other impurities. The inner and outer ring of the bearing after many times of circular grinding treatment can ensure its concentricity, greatly improve the dynamic performance of the bearing and prolong the service life of the bearing.
The motor will usually stop running or be stuck because of lacking of oiling. Without the lubricating oil, the blades which lead to motor rotation will be not resistant to friction, thus generating dust. While the abrasive resistance of M2 handpiece is 50% higher than that of the others. This can directly improve the performance of the motor.
