Precision Machining

Milling

Acutec is established as a premier long and short run part milling facility in northwestern Pennsylvania and the world.

All Acutec milling centers are equipped with Renishaw touch probes. We can machine in four- and five-axis and machine parts from .250 inches diameter to 20 inches diameter. Our horizontal machining centers have automatic pallet changers.

Tools are gaged and set with a Speroni Optical Presetters and offsets are uploaded to a local server. All mill programs are stored and transmitted via a shop-wide DNC and ethernet connection system.

Turning

Our CNC Turning Centers support large diameter turning at close tolerances. Extensive resources of tooling, gaging, and quality machines enable Acutec machines to run at maximum productivity and maintain unmatched quality.

We have turning capabilities from .250″ diameter up to 16.5 inches in diameter. For turning up to 1.625 inches in diameter we can turn up to 27.5 inches long. We can bar feed material up to 3 inch diameter and 12 feet long. Many of our turning centers are set up to run in cellular arrangements. We also have turning centers with live tooling and dual turrets for maximum productivity.

We can turn within .0005″ tolerance and with finishes of 16√. For parts under .0005″ tolerance, we employ our own CNC honing and grinding in house. All programs are stored and transmitted via a shop-wide DNC and ethernet connection system.

Quality Assurance

Intrinsic Quality
When a part is processed at Acutec, a feature-based inspection criteria guide is also created for every dimension at every operation. Every machine workcenter is equipped with surface plates and the necessary inspection equipment to allow operators to perform consistent and reliable in-process inspection. At Acutec, quality is not a department, it’s an integral part of what we do.

Continuous Improvement Philosophy
At Acutec, every single employee is dedicated full-time to continuous improvement projects. We don’t employ button-pushers. Our people–at all levels of the organization–think. We recognize that we are in competition with the world every single day. Using the lean manufacturing philosophy, Six Sigma methodology, AS9100:2009 and our ISO 9001:2008 and NADCAP certifications, we are able to drive down costs, improve quality, and reduce lead times through all areas of our business. This allows us to provide you with high quality components in less time and at a lower cost than the competition.

Strategic Partnerships

Acutec has partnered with an extensive network of outside service suppliers to meet the special process requirements common to aerospace parts. Acutec coordinates the processes of heat treat, shot peening, specialized coatings/plating, and others. Outside service suppliers are selected based on customer directive , NADCAP accreditation, and their ability to meet or exceed quality and delivery standards.

Outside service suppliers are evaluated on a constant basis to ensure that quality and delivery requirements are met.

New part introduction includes a rigorous process, including APQP and FMEA to ensure scope of work is clear and potential concerns are addressed timely and completely.
