We partner with local Heat Treaters, Platers, and custom Plating Specialists to give our customer a completed part. Materials used are 303 Stainless Steel, 6061 Aluminum, 17-4 PH, and A2 Tool Steel. The customer is a custom machine builder in Mooresville, North Carolina. We inventory parts as well for these components so that parts are ready when needed. Larger size runs help keep costs low as well.
Precision Machining: Custom extruding die
We machine a family of simple aluminum Spacers for an electronics manufacturer in Charlotte, North Carolina. The Inside Diameter and outside diameter are always the same on this group of parts but the overall length varies with each order. We had a custom extruding die made and purchased a large quantity of aluminum tubing in advance so that we could offer quick turn around and aggressive pricing on this simple spacer. Order quantities are generally 500- 3000 pieces.
Precision Machining: Wire EDM
We cut windows out of a sleeve for a Steam Turbine manufacturer, one of the largest Energy companies in the world. We use one of our 3 Wire EDM machines to cut out the windows. The main sleeve is hardened and ground and needs to be cut stress free. Our customer experimented with many different machining methods, but none has been as successful as Wire EDM. The expensive components require extreme care as they are nearly complete when they arrive. This job also involves short notice and demanding turnaround times. There is no room for error. This Energy company is located in Charlotte, North Carolina.
Precision Machining: Wire EDM for prototypes and production runs
We make a special custom screw driver used to remove anti-theft cables placed on electronics. These cables are used by most big box electronics stores. Omega made the prototypes and then the initial production runs with production quantities of 6000 at a time. The customer took the production runs to China at one point but could not get an acceptable quality in the final part. We came up with a hybrid solution where the customer now provides us with standard screw drivers bought cost effectively from overseas, and we modify them to meet the customer specifications. The customer gets the low price and the part they need. Our customer, a multi-national security company, is located in Charlotte, North Carolina.
Precision Machining: CNC Turning
We make a small threaded and knurled nut made of Nitronic 60 for a medical instrument manufacturer. This part is made in two operations on a CNC turning center. Material Certification is required and we perform 100% inspection on critical features. This part is run in lots of 500. The customer is in Rochester, NY.
Precision Machining: CNC Router
We manufacture custom aluminum door handles for a retail jewelry store chain. In previous attempts they were unable to get the look they wanted using a CNC Router because the pattern was too intricate. We took their design and our machining expertise and gave them what they were looking for. We did a minor redesign, and successfully made these parts with milling machines. These handles are then chrome plated to make them shine. The customer was delighted that the door handle kits we made went together perfectly and had the look and feel that they wanted. They look forward to opening 50 more retail stores in the coming year across the country. Our customer is located in Concord, NC and has another location in Florida.
Precision Machining: Wire EDM, Conventional EDM, and an EDM Hole Drill
We manufacture custom components used for Ultrasonic Testing in the Nuclear Power Industry. These calibration blocks are used to simulate flaws found in the piping systems and the vessels in nuclear power plants. Omega uses Wire EDM, Conventional EDM, and an EDM Hole Drill to intentionally put features in parts, simulating flaws that can naturally occur. Technicians use these calibration blocks for training purposes. It teaches them to identify real life cracks or damage that is otherwise obscured or hard to detect in a nuclear power plant. Wire EDM technology allows us to create features in these parts that cannot be machined conventionally. This work often requires creative solutions to put a crack with specific geometry in the middle of a part. This customer is an expert on welding procedures required to build and maintain a nuclear power plant. They are located in Concord, NC.
Precision Machining: RAM EDM
We work with a high volume Bearing Manufacturer that is using Eddy Current Testing to locate flaws in tapered roller bearing pins. Omega generates nearly microscopic flaws on customer supplied pins using RAM EDM. These pins are then run through the customer’s manufacturing process as a test to verify that their inspection equipment can detect the defective pins. This customer has multiple locations in North and South Carolina.
Precision Machining: EDM and Grinding
We work with an Engineering firm in the Atlanta area that designs and builds special machines mainly for the paper and pulp industry. They use us both for overflow work, due to the cyclical nature of their business, and to manufacture the more intricate parts that use processes that we are expert at such as EDM and Grinding. The parts we make for them are always different, low volume, and seldom repeat. They like us for our flexibility, versatility, quick response and reasonable pricing. They know that they can get a quality job on short notice.
Precision Machining: CNC, manual machines and prototypes
We work with the Manufacturing Engineering and Packaging Team of a pharmaceutical company to make parts for their factory production lines. This includes making repair parts to keep production lines running, improving existing components to prevent future disruptions.
