General Fitter Responsibilities Quiz

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.
