How work the maintenance department in RMG sector.

Maintenance:

The technical meaning of maintenance involves functional checks, servicing, repairing or replacing of necessary devices, equipment, machinery, building infrastructure, and supporting utilities in industrial, business, governmental, and residential installations.

Types of maintenance:

1. Corrective maintenance.

2. Predictive maintenance.

3. Preventive or schedule maintenance.

4. Remedial maintenance.

5. Restorative maintenance\emergency maintenance.

RMG sector follows mainly three types and overhaul.

Preventive maintenance: preventative maintenance is maintenance that is regularly performed on a piece of equipment to lessen the likelihood of it failing. It is performed while the equipment is still working so that it does not break down unexpectedly. In terms of the complexity of this maintenance strategy, it falls between reactive (or run-to-failure) maintenance and predictive maintenance.

Corrective maintenance: Corrective maintenance is maintenance performed to return equipment to proper working order. Depending on the context of its use it may refer to maintenance due to a breakdown, or maintenance identified through a condition monitoring program.

Predictive maintenance: Predictive maintenance is a technique to predict future failure point of a machine component, so that the component can be replaced, based on a plan, just before it fails. Thus, equipment downtime is minimized and the component lifetime is maximized.

Overhaul (zero hours maintenance): The set of tasks whose goal is to review the equipment at scheduled intervals before appearing any failure. The aim is to ensure with high probability a good working time fixed in advance.

Tools and their function:

• Combination tools: Tightening and loosening of nut & bolts.
• Socket Ratchet set: Tightening of the nut & bolts.
• Slide Range: Tightening and loosening of nut & bolts.
• Pliers: Tightening and loosening of the nut & bolts, grip the object.
• Threat cutting Tools: To cut the threat.
• Bearing Puller: To assist the opening of bearing from the shaft.
• Pipe Range: Tightening and loosening of round types of objects.
• Pipe cutting tools: To pipe cut.
• Scissor: To cut gaskets & steel sheet.
• Oil can: Oiling of moving parts.
• Drill M/C and Drill bit: For drilling.
• Grease Gum: For greasing of moving parts.
• Girding M/C: For grinding & cutting of melt steel.
• File: For smooth surface.
• Hammer: For scaling & right angling.
• Hacksaw blade: For metal cutting.

Solution

Procedure of maintenance of a sewing machine:

DB board check for wire loose.

DB Board clean.

Power on by the main circuit board.

Power supply to m/c line.

Join the plug in the bazaar.

Check the oil level.

Ensure cleanliness of the machine.

All parts of the whole machine are checked.

Switch on.

Run the machine.

If comes layout change gauge set.

Check by the operator.

Run the machine.

Remarks: 

Maintenance is an important part that keeps the machine in an optimal working condition. RMG Preventive maintenance& Breakdown maintenance carried out. Before layout planning, machine maintenance is done so that during production machine break down does not work.
