Why Do Spindle Devices Experience Difficult Startup in Winter?

In winter, spindle devices often face difficulties during startup due to several factors that are exacerbated by cold temperatures. Understanding these challenges and implementing corrective measures can ensure smooth operation and prevent damage to the equipment.

Causes of Difficult Startup in Winter  

1. Increased Lubricant Viscosity:In cold environments, the viscosity of lubricants increases, which raises friction resistance and makes it harder for the spindle to start.


2. Thermal Expansion and Contraction: The metal components inside the equipment may undergo deformation due to thermal expansion and contraction, further hindering the normal startup of the device.


3. Unstable or Low Power Supply:Fluctuations or insufficient power supply can also prevent the spindle from starting correctly.

Solutions to Overcome Difficult Startup in Winter 

1. Preheat the Equipment and Adjust the Chiller Temperature: 1)Preheat the Spindle and Bearings:Before starting the equipment, preheating the spindle and bearings can help increase the temperature of the lubricants and reduce their viscosity. 2)Adjust the Chiller Temperature:Set the spindle chiller temperature to operate within the 20-30°C range. This helps maintain the lubricants' flowability, making startup smoother and more efficient.


2. Check and Stabilize Power Supply Voltage: 1)Ensure Stable Voltage: It is important to check the power supply voltage and make sure it is stable and meets the device's requirements. 2)Use Voltage Stabilizers: If the voltage is unstable or too low, using a voltage stabilizer or adjusting the network voltage can help ensure that the device receives the necessary power for startup.


3. Switch to Low-Temperature Lubricants: 1)Use Appropriate Low-Temperature Lubricants:Before the onset of winter, replace the existing lubricants with those that are specially designed for cold environments. 2)Select Lubricants with Low Viscosity:Choose lubricants with low viscosity, excellent low-temperature flowability, and superior lubrication performance to reduce friction and prevent startup issues.
