Manufacturing of oil chiller and water chiller of cnc milling spindles

Cooling chiller for CNC milling and turning machine tool equipment
With the increase of more accurate and smaller tolerances in the machine tool industry, it is necessary to maintain the temperature of the machine, spindle and work piece at the optimal level. During the operations of milling, turning, grinding, cutting, drilling, etc., the machine and the work piece get too hot (especially modern CNC machines, they have a very high rotational speed and chipping, which generate a lot of heat) and They definitely need a cooling system. Today, with the more complex designs of machine tool spindles, the need for proper cooling of the spindle has increased. In most machines, the spindle is exposed to damages caused by overheating
An increase in temperature brings the following problems:
1. Increase in production waste
2. Reduced tool life
3. Loss of coolant due to high evaporation rate
4. Further erosion of machine tool equipment
5. Reducing the useful life of the coolant
If the spindle is well cooled, it has the following advantages:
1. Longer lifespan
2. Higher accuracy
3. Constant strength during the machining process
Spindles that are directly connected to the motor are more exposed to heat because the stator and rotor of the electric motor are connected to the surrounding housing and the spindle shaft and generate heat themselves, which is added to the heat generated by the spindle.
Advantages of using chillers and mini chillers in the machine tool industry:
1. Optimizing the production process with more precision and smaller tolerances
2. Keeping the tolerance value constant during the process (by keeping the temperature of the spindle and tool constant with an accuracy of 1°C)
3. Optimizing tool working temperature and reducing production waste
4. Ensuring the reduction of erosion of moving parts
5. Reduced CNC machine maintenance
6. Reducing the rate of erosion and evaporation of the cooling liquid (cooling oil)
7. Reduction of pollution due to the reduction of smoke and steam produced during machining
Chiller and mini chiller devices are among the most accurate and efficient cooling systems in the industry. By using a chiller or mini chiller and precise temperature control (from below zero to a few degrees above zero), the life of the CNC machine increases and the accuracy of the machining operation increases.
