Blending Experience in CNC Machining and Grinding with Innovative Valve Component Manufacturing Solutions in Knoxville, TN.

Ripley Machine has been in operation and serving the Knoxville, Tennessee area since the 1950s. In 1994, Quentin Bensink purchased Bornand Company and incorporated the company as Ripley Machine and Tool Company, Inc. Quentin continued to own and expand the business for the next 21 years. In 2012 Quentin was joined in management by his grandson Andrew Reinwald. In January of 2015, Andrew purchased the company from Quentin and became President. Quentin remained with the company through 2017 as an integral part of guidance for Andrew as the business transitioned ownership. Andrew remains committed to the core Christian values that Quentin operated the company through while continuing to explore opportunities to expand and develop the company. Andrew remains committed to the positive impact that the business can have on others through employment and charitable contributions.

It is the goal of Ripley Machine and Tool Company to focus on continuously improving and developing new business avenues so that we are able to positively impact the lives of our employees and their families, our customers and our community. By developing a close working relationship with our customers we understand their requirements, and can often ‘fill in the blanks’ and question inconsistencies in information from our customers.
