Key Differences ( CG vs TG&P )
| Feature | TG&P Bar | Centerless Ground (CG) |
|---|---|---|
| Tolerance | Tight | Very tight |
| Surface Finish | Smooth | Superior |
| Straightness | Good | Excellent |
| Final Sizing | Pre-sized | Final size control |
What Is TG&P Used For?
- General precision shafting
- Ready-to-machine bar
- Applications with standard tolerance requirements
What Is Centerless Ground Used For?
- Ultra-tight tolerance parts
- High-precision components
- Final diameter control
- Medical and aerospace applications
When to Choose TG&P
Use TG&P when:
- Standard precision is acceptable
- Cost needs to be controlled
- Minimal machining is required
When to Choose Centerless Ground
Use CG when:
- Tight tolerances are critical
- Surface finish requirements are high
- Parts require exact sizing
Upgrade Path
Many applications start with TG&P and are then:
➡️ Centerless ground to final size
This allows for:
- Better accuracy
- Improved finish
- Consistent results
