Due to the unique design of XEBEC products, we have achieved optimal success when Deburring Technologies technical personnel assist in the selection of proper tool and operating parameters. Provided our representative has reviewed an application and provided processing recommendations, we are pleased to provide reasonable quantities of test product with a “Guaranteed Trial” purchase order. Such product will be invoiced and is payable per our normal NET – 30 DAY terms. Should the product not perform as promised, simply contact us for a return authorization within forty five (45) days of purchase with a written report of how the product failed to meet the promised performance. Once we have received and inspected the product we will issue full credit for the returned product. All returns for other than guaranteed trial performance must be received within thirty (30) days from date of purchase and be received in new condition in the original packaging. Once we have received and inspected the product we will issue full credit for the returned product.
