What spare parts do I need for my motor motor rotor (single station) spot welding machine and how do I set up a guaranteed inventory?

What spare parts do I need and how do I keep them in stock for the spot welder for motor rotors (single station)?

In response to your request, here are the details of the spare parts required for the motor motor rotor (single station) spot welder and how to set up a guaranteed stock:

Spare parts:

1、Molds: as the key components of spot welding machine, you need to prepare a certain number of molds for replacement and maintenance.

2、rotor: as the main material of production, need to prepare sufficient rotor according to the production plan.

3、crowbar (copper ring meson): also need to prepare enough crowbar according to the production demand.

Guarantee inventory setup:

• Demand analysis: First, the uncertainty of demand needs to be quantified, i.e., the accuracy of the forecast and the error between the actual demand and the forecast.

  
  

• Supply analysis: Consider the uncertainty of supply, such as the lead time and reliability of suppliers, which can be assessed through historical data and supplier communication.

  
  

• Service level: According to the service level requirement, for example, it is hoped that there will be no stock-out 95% of the time, corresponding to a z-value (quantile of standard normal distribution) of 1.65, which can be used to calculate the guaranteed inventory.

  
  

• Safeguarded Stock Calculation Formula: The safeguarded stock can be calculated by the following formula: SS = z * SQRT(σd^2 * μL + σL^2 * μd^2), where SS is the safeguarded stock, z is the z-value corresponding to the service level, σd is the standard deviation of the demand, μL is the mean of the supply cycle, σL is the standard deviation of the supply, μd is the mean of the demand.

  
  

• Regular Inventory: Regularly conduct all inventory counts of the inventory to ensure that the accounts are in line with the actual situation and to avoid blind increase or decrease of the inventory.

  
  

• Reasonable structure: According to the product characteristics and market demand, the inventory structure is reasonably configured to reduce the slow-moving inventory.

  
  

• Informatization management: Improve the automation and intelligence of inventory management with the help of informatization technology and management tools.

Through the above methods, we can set up a reasonable guaranteed inventory for the motor rotor spot welder to ensure the continuity of production and the timeliness of spare parts supply.
