Turbo Abrasive Machining – Lean DeburringTurbo Abrasive Machining – Lean Deburring
This abrasive fliudized bed machining center is capable of processing 20 inch (500mm) disks
Turbo Abrasive Machining in Motion…
INDUSTRY: Aerospace
PART: Turbine; Compressor Disks
PROBLEM: Reduce deburring timeand cost; develop edge-contour, develop isotropic surfaces, develop compressive stress
PROCESS(ES) REPLACED:hand-tools; pencil grinders
TURBOFINISH SOLUTION:Implement TAM Process withTF-Turbo-Abrasive Machine
TURBOFINISH PROCESS IMPROVEMENT:10 inch disk processing time reduced from 3 hrs to 3 min. Per part abrasive cost reduced to 0.15 each.20 inch disk processing time reduced from 3-10 hrs to 6 min.
Turbo Abrasive Machining Basics Lean Deburring Case Study
TAM vs. Manual Deburring Service Improvement, fatigue resistance TAM vs. Manual Deburring Service Improvement, fatigue resistance
Also, destructive testing of steel plates:
Conventional ground plates fail after (1.1 – 1.5) * 104 cyclesTAM process plates fail after (3 – 3.75) * 104 cycles
COMPARISONS:
Fatigue Limit Value σ_1
Grinding = 250 + 43 MPa
TAM = 330 + 20 Mpa
Spin Test Results: (cycles)Disks with Manual treatment
Cracks appear: 2600 + 700
Disks destruct: 5685 + 335
Disks with TAM treatment
Cracks appear: 7300 + 700
Disks Destruct: 13090 + 450
IMPORTANTTAKE AWAYPOINT
LEAN Rapid Edge Contour – Isotropic Finish of Large Rotational Aerospace Components with TAM
Turbo Abrasive Machining technology replaces batch and queue hand deburr with LEAN cellular machining concept.
Drives down defect rate to near zero. Drives down WIP from hours to minutes in single piece continuous flow
