Study Notes
General Fitter Responsibilities
- Assembling and maintaining mechanical components is the primary responsibility of a general fitter.
Hand Tools
- A lathe machine is not a hand tool. Spanner, screwdriver, and hammer are hand tools.
Vernier Caliper
- The least count of a vernier caliper is 0.01 mm.
Nut and Bolt Tools
- A spanner is used for tightening or loosening nuts and bolts.
Bearings
- Bearings reduce friction.
Gaskets
- Gaskets prevent leakage between mating surfaces.
Shaft Couplings
- Shaft couplings connect shafts for power transmission.
Tool Materials
- High carbon steel is commonly used for hammers and spanners.
Stainless Steel Properties
- Stainless steel's corrosion resistance makes it suitable for mechanical fittings.
Metal Part Finishing
- Filing is used to remove burrs and sharp edges from metal parts.
Shaft Alignment Tool
- A dial gauge is the most suitable tool for checking shaft alignment.
Bearing Maintenance
- Worn-out bearings should be replaced.
Personal Protective Equipment (PPE)
- Safety gloves are part of PPE.
Lockout/Tagout System
- The lockout/tagout system prevents accidental machine operation during maintenance.
Preventive Maintenance
- Preventive maintenance involves regular inspections to avoid breakdowns, not just repairing after failure.
Excessive Machine Vibration
- Checking for loose components is the first step when a machine vibrates excessively.
Loosening Stuck Bolts
- Heating the bolt slightly and using penetrating oil is a method to loosen a stuck bolt.
Reducing Wear and Tear
- Proper lubrication reduces wear and tear on moving parts.
Hydraulic Systems Medium
- Hydraulic systems use oil for operation.
TMT Godets in IDY Manufacturing
- TMT godets maintain tension and control yarn speed in IDY manufacturing.
TMT Goded Operation Stage
- TMT godets are primarily used during the drawing and stretching stage of IDY manufacturing.
Heating Element in TMT Godet Function
- The heating element in TMT godets maintains the required yarn temperature for stretching.
Smooth Goded Rotation
- Bearings ensure smooth rotation in a godet.
Goded Surface Coating
- Chrome or ceramic coatings are typical on a TMT godet surface.
Avoiding Yarn Damage
- A smooth, scratch-free godet surface prevents yarn damage during operation.
Excessive Noise in TMT Godet
- Misaligned bearings are a primary cause of excessive noise in TMT godet assemblies.
Oil Seal Function
- Oil seals prevent lubricant loss and contaminant entry.
Goded Replacement Procedure
- Isolating the machine and ensuring it's powered off is the first step in godet replacement.
Detecting Goded Wear
- Visual inspection for scratches or grooves detects godet wear.
Goded Rotation Issues
- Worn-out bearings cause nonsmooth godet rotation.
