The Challenge

The customer is manufacturing automotive pump housings made from Grey Cast Iron using a Haas VF4 machining center with water soluble coolant.

The tools had a tendency to break, and the customer wanted to eliminate the inconsistent tool life. The machine down-time increased the cost-per-hole.

The T-A GEN2 met the customer’s requirements by providing consistency and eliminating machine down-time. In the end, the lower-priced YG-1 tool ended up costing much more in terms of tool life, machine down-time, and the overall inconvenience of inconsistent tool performance.

Product: T-A GEN2
Objective: (1) Decrease tool inconsistency
(2) Decrease cost per hole
Industry: Automotive
Part: Pump housing
Material: Grey cast iron
Hole Ø: 0.843" (21.412mm)
Hole Depth: 1.500" (38.100mm)
