Maintenance
Maintenance may be defined as the chronological process of systematic activities done for keeping the mc or equipment’s at the heat level for well run or its proper services. Machines play a principal role in determining the productivity of an industry, the quality of its products, power consumption and working atmosphere. In spinning mill, maintenance of spinning machines are very important for getting proper efficiency. Because the performance of the spinning mill depends on the proper maintenance of spinning machines.

All the textile machinery both process and related ones are high performance machinery and they have to maintained well to ensure their high performance and efficiency. Also proper maintenance ensures their long operating life.

Types of Maintenance of Machines in Yarn Spinning Mill:
The following types of maintenance are carried out in spinning machines:

1. Schedule Maintenance: Here mainly all the machines are checked on the basis of a fixed schedule of time. Different machine parts are opened, cleaned, lubricated, gauged and replaced if necessary.

2. Predictive Maintenance: This type includes maintenance of spinning machines part on the basis of suspicion that they consists problem and will cause greater problem in future. It also includes the gear changes that are done to adjust count, ktex etc of machinery and overhauling.

3. Breakdown Maintenance: When a machine stops due to failure of machine parts, then it is called machine breakdown. The maintenance that is done to repair and make it ready to run is called breakdown maintenance.

The points that are checked during the maintenance of different spinning machines as well as different lubricating points are given in the following section –
