BROACHING TOOL LIFE EXTENDED SIGNIFICANTLY THROUGH CRYOGENIC TREATMENT

Deep cryogenic treatment of broaches at temperature levels below -300°F have shown significant improvement in extending broach life four to five times. Cryogenic treatment of these broaches has allowed the broaches to produce between four and five times the amount of parts. Broaches saw a minimum of 300%+ increase in lifetime after cryogenic treatment.

	APPLICATIONS	AVG. LIFE BEFORE TREATMENT	AVG. LIFE AFTER TREATMENT	PERCENT IMPROVEMENT
	C1029 Steel Torque Tube Yoke	1810 PARTS	8620 PARTS	376%
	Forged Connecting Rods	1500 PARTS	8600 PARTS	573%
