A CNC machining center , also known as a CNC machine tool, is a computer numerical control (CNC) machine, an automated machine controlled by a program. The control system processes the program containing control codes or other instructions, decodes them via a computer, and directs the machine to perform specified actions. This process uses cutting tools to transform raw materials into semi-finished parts.
 
During operation, the CNC machining center generates heat from the spindle, requiring a cooling system to maintain optimal performance. To address this, a cooling chiller is used to provide water circulation cooling. This type of chiller is often referred to as a CNC machine coolant chillers.
 
A CNC machining center chiller is a cooling device that ensures constant temperature, flow, and pressure of the cooling water. It typically consists of the following components:
Cooling water tank  
Circulation water pump  
Refrigeration compressor  
Condenser and evaporator  
Cooling fan  
Refrigeration controller and other related control components.
 
This system effectively manages the heat generated during machining, ensuring the CNC machine runs smoothly and reliably, extending its operational lifespan and enhancing production efficiency.

Yes, we do.
The coolant coolers, fluid chillers, and other chillers we currently showcase are among the most in-demand types in the market. LNEYA adjusts its product lineup according to market and customer needs, discontinuing low-demand products and updating with high-demand ones. For example, LNEYA previously phased out the LX and FX series of low-temperature chillers and replaced them with the LTZ variable frequency series.
 
In addition, based on customer requirements, LNEYA engineers can develop fully customized refrigeration and temperature control systems, offering a complete service package from design to installation and commissioning. This ensures that the chiller units are perfectly suited to the customer’s application, allowing for lower coordination costs and manageable project timelines.

LNEYA coolant chillers typically use water, ethylene glycol, ethylene glycol water solution, and mixed refrigerants as cooling agents.  

For our LTZ-45 series, we exclusively use the R404A mixed refrigerant.

If you have any specific requirements for coolants, please feel free to contact us. We will customize a solution tailored specifically to your needs.
