Complete Sets of Spindle
If Siemens 808D or Syntec controller is selected:
8000rpm: standard spindle speed for DATAN vertical machining centers, which is of spindle belt drive;
10000rpm: Beijing CTB high speed spindle motor should be adopted. The spindle is of belt drive. In this case, customers need to pay additional 500usd basis on the basis of 8000rpm;
12000rpm: Taiwan SOLPWER high spindle motor, high-speed spindle of little steel ball bearings and spindle oil cooler should be adopted. The main motor and the spindle is of belt drive. In this case, customers need to pay additional 1,800usd at the basis of 8000rpm;
15000rpm: Taiwan SOLPWER high spindle motor, high-speed spindle of ceramic ball bearings and spindle oil cooler should be adopted. The main motor is directly connected with the spindle. In this case, customers need to pay additional 4,300usd at the basis of 8000rpm.
Note:
1. The spindle speed mentioned here is the max. spindle speed, which is different from the speed used in practice. A lot of heat will be generated due to high speed rotation of the spindle. Thermal expansion of the bearings will easily be caused. Therefore, in the absence of peripheral cooling device, the long time running speed can only be calculated at 80% of the max. speed; If a long-term operation at high speed is needed, oil cooler is suggested then.
Even so, in most cases, the 8000 rpm(10000 rpm) spindle speed has been able to meet the processing needs of most customers.
If the dia. of the tool is particularly small and the material to be processed is special (like graphite), you can consider choosing higher spindle speed, but the rigidity of the spindle will mostly likely be weakened.
2. Except for the above recommended configuration, customized configuration is also available according to customer’s needs.
3. The above just set cnc machining center ME850 machining center as an example. The price varies with different model, thus please contact our sales engineer for details.
If FANUC, Mitsubishi or Siemens 828D controller is selected:
10000rpm: standard spindle speed for DATAN vertical machining centers, which is of spindle belt drive;
12000 rpm: the max. Spindle motor for Mitsubishi system can be 5.5/7.5kw;
the max. Spindle motor for FANUC system can be 7.5/11kw;
the max. Spindle motor for Siemens 828D system can be 9kw;
High-speed spindle of little steel ball bearings and spindle oil cooler should be adopted. The main motor and the spindle is of belt drive. In this case, customers need to pay additional 1,800usd at the basis of 10000rpm;
Note:
Electric spindle is still needed when your actual speed demand is over 15000rpm. (for Complete Spindle)
It is of bus interconnection when equipped with FANUC, Mitsubishi, Siemens 828D controller. Its main motor and the numerical control system must be consistent thus price is relatively high.
