Use high precision standard ER nuts
Use standard ER collet：ER20、ER25、ER32、ER40、ER50
Locking method: external locking, internal locking
External Lock Internal lock nut Internal Lock
As can be seen from the perspective view:
Compared with the external locking tool holder, the tool overhang distance of the internal locking tool holder is shorter and the internal locking clamping is more stable.
Therefore, the use of the internal locking tool holder to process the workpiece has stronger rigidity, higher efficiency and smaller interference range.
Ultra-low temperature, low noise technology, using NSK bearings imported from Japan, 1:1 maximum speed can reach 6000 rpm, 8000 rpm, 10000 rpm, 12000 rpm, three levels, output accuracy 0.002mm.
Application scenarios: punching, tapping, milling, drilling, milling, grinding and tapping, etc.
1. The main body of the DRAKE brand NEW MODEL BMT-0 degree power tool holder is made of forged steel in one piece,
and the processing is also done by a five-axis machine tool at one time, which ensures the accuracy of the relevant geometric tolerances.
The advantages are: the thermal expansion coefficient of forged steel is the same as that of bearing steel,
and the bearing clearance will not be too large or too small due to cold or heat, ensuring the stability and service life of the bearing operation.
Because it always maintains the consistency of the bearing clearance,
it ensures that the tool holder does not vibrate when the machine is cold and does not lock when the machine is hot, making the tool life longer.
2. The front and rear spindles of new model structure use NSK tapered roller bearings in combination,
which has a greater load-bearing capacity and stronger cutting, greatly improving the processing efficiency, tool life and surface finish.
3. The bearing grease uses SKF special bearing grease, which has mechanical stability and suitable adhesion, avoids lubrication loss, and is maintenance-free for life.
4. The new model spindle head adopts a bowl-shaped fluororubber end face water seal ring,
which can withstand high speed and high temperature without easy wear and tear, has a long service life,
and can also adjust the damping force of the spindle, so that when the turret changes the tool position,
the drive shaft will not be inertial and cannot be fixed at the zero point in time. In other words,
this power tool holder can brake in time and achieve synchronous tool change with the drive shaft,
which is smoother. (This sealing structure has obtained a national patent)
5. The new design of the tool holder can be immersed in water for a long time without getting wet.
6. The drive shaft adopts a soft sleeve, the purpose of which is to protect the module in the turret from being damaged due to hard collision during the tool change process.
