Quality is built into their products and monitored at every step in the production process. Each job starts with careful adherence to print specifications for both raw material and part geometry.

Customers are encouraged to invite KKSP Precision Machining to participate in their product design discussions during which their engineers can provide meaningful Value Added/Value Engineering suggestions which can often result in important cost savings.

KKSP maintains complete and verifiable lot traceability of both raw materials and part manufacturing history for all products.

KKSP maintains state-of-the-art touch-free gauging and verification equipment.  Direct input gauging is also used to eliminate the potential for human error in measuring critical dimensions. This data can be converted into SPC documentation and statistically analyzed to continuously improve the process.
