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: Prototypes and Wire EDM production run
Client: Security Company in Charlotte, North Carolina
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: part Redesign and CNC Router
Client: Retail Jewelry Store in Concord, NC and has another location in Florida
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 technology
Client: Ultrasonic Testing in the Nuclear Power Industry in North Carolina
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. 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
Client: Bearing Manufacturer in South Carolina and North Carolina
We work with a high volume Bearing Manufacturer that is using Eddy Current Testing to locate flaws in tapered
