FAQ – Everything You Need to Know About Steel Turned Ground Polished Shafts
A turned ground polished steel shaft, also known as TGP shafts or precision shafts, is a solid cylindrical steel product that has undergone precision finishing processes to achieve a smooth surface finish and tight dimensional tolerances.
The turning, grinding, and polishing processes remove surface imperfections, improve straightness, and ensure consistent dimensional accuracy.
These products are commonly referred to as Turned Ground Polished Shafts in industrial and mechanical applications where precision and surface quality are required.
The main difference lies in surface finish and dimensional precision.
- HR (Hot Rolled) round bar
o Rougher surface finish
o Wider dimensional tolerances
o Used for general and structural applications
- Turned Ground Polished Shaft
o Smooth and uniform surface finish
o Improved dimensional accuracy and tighter tolerances
o Ideal for machining and precision mechanical applications
Turned Ground Polished Shafts are preferred when high precision and surface quality are required.
Turned Ground Polished Shafts are available in several grades designed for mechanical applications:
- 1045 Steel
o Medium carbon steel
o Good balance between strength and machinability
o Commonly used for general mechanical components
- 1144 Steel (Stressproof)
o Resulfurized carbon steel
o Improved machinability
o Excellent dimensional stability
o Reduced internal stresses for precision applications
4140 Steel
o Chromium-molybdenum alloy steel
o High mechanical strength
o Used for demanding industrial applications
