Super Abrasive Machining

SAM Advantages

Super Abrasive Machining represents a virtually untapped process technology that greatly enhances PM’s ability to further its offering of complex and cost effective components

Grinding at machining rates
Both stock removal and finishing
Predicable wheel wear / no breakage
Highly productive
NO MACHINIBILITY ADDITIVES
Minimal burr issues
No wheel dressing = rate
High dimensional repeatability
Low pressures- no part distortion or damage
Heat treated or as sintered (soft)
CNC and machine features allows massive stock removal and tight tolerance finishing in the same chucking/machine cycle

Circumferential/Radial cutting

Facing

Slotting, flats, geometries perpendicular to the direction of pressing

5 AXIS SAM

Grinding	Machining	Super Abrasive Machining
Typically a finishing operation	Both stock removal and finishing	Both stock removal and finishing
Hard or heat treated materials	Sintered materials -Hard turning advancements -Machinability additives	Heat treated or as sintered materials NO MACHINIBILITY ADDITIVES
High work piece pressures- distortion/damage	Tool wear and breakage	Predictable wheel wear/no breakage Low pressures-no part distortion/damage Minimal burr issues
Slow	Productive	Highly Productive
Wheel dressing required	Traditionally performed on PM to improve tolerance or add certain features	No wheel wear No wheel dressing
Costly		Grinding stock removal at machining rates
A necessary evil	Used on interrupted cuts "because we had no other choice"	CNC and machine features allows massive stock removal and tight tolerance finishing in the same chucking/machine cycle
