Precision CNC Machining


Impossible Tolerances? Unbelievable Complexity? Count on Ego Manufacturing Group

When you need a machine shop capable of machining complex components with the highest precision, you can count on Ego Manufacturing Group. Our team of highly skilled CNC machinists has the experience and expertise required to produce close tolerance components with 1 to 100 micron accuracy. If other CNC machine shops CAN’T do it, Ego WANTS to. Give us a call today to discuss the manufacturability and surface finish of your design ideas or to learn more about the capabilities of our facility, machines, and staff.


Our precision machining service is supported by our experienced specialists and CNC machinists who are experts in programming, fixture design, and development. Ultra-precision requires our machinists to possess a deep understanding of a machine’s behavior – not just programming and running in accordance with a manual. CNC machinists’ familiar with their machines give them the ability to push the machines beyond the manufacturers intended design and tolerance capabilities, maximizing their performance when needed. With knowledgeable, industry leading ultra precision machining professionals on our team, we have been able to develop processes achieving practically impossible levels of perfection with the manipulation of temperature compensation curves and control.

Precision CNC Machining


If you are looking for the sharpest, cleanest, and most precise CNC machining company in the nation, Ego has the capabilities you need to get your orders cut and delivered on time and in budget. Our precision machining services are highly sought after in multiple industries because we require our CNC machinists to truly understand their machine’s behaviors – not just the electronic makeup, technical controls, and power button. By hiring true professionals and not just standard workers to operate our CNC machines, our customers receive the best precision components they need with the repeatable accuracy they demand. We perform a number of ultra precision machining services, such as:


a. 3 and 4 Axis Milling
b. 5 Axis Machining
c. Super Precision Lathes
d. Wire EDM
e. Sink/RAM/Plunge EDM



For customers seeking precision CNC machining, we recommend our 4 and 5 axis mill machining. Two of the most accurate machining options in the industry today, these precision machining methods give our machinists the most potential for close and exact cuts. Owens Industries’ 5 axis milling services have an impressive tolerance range, able to cut down from 100 to 1 micron. Doesn’t sound accurate enough for the needs of your company? Our state-of-the-art, specially calibrated 5 axis machines’ tolerance range breaks down to a thousandth of an inch, bringing with it the tightest precision machining capabilities today:


a. 1 Micron: .000039”
b. 100 Microns: .003937”




Wire EDM for Guaranteed Precision

Although it may initially be overwhelming, getting a handle on the full scope of CNC machining capabilities available and how they can benefit your products is easy once CNC techniques have been properly defined. Starting with wire electrical discharge machining (EDM), Ego Manufacturing Group would define an EDM machine as one of the most effective CNC indentation and cutting methods available today.

“EDM machining services utilize electrical discharges to make cuts in hard metals.”

Applications best suited for the EDM process are those characterized by extremely exacting tolerances, making it difficult or impossible to handle with any other material removal process. EDM machining is a no-contact and stress free process, meaning it is also best suited for making fragile parts unable to handle the stress of a normal CNC machining process. (Printer hammers, graphite electrode, miniature gears, and any part featuring honeycomb shapes).

With your fresh knowledge of what EDM machining is, you may now be looking for the best EDM precision machining services to cut your production costs and reduce your turnaround times. If so, Ego Manufacturing Group has the precise CNC machining solution for you. Our wire EDM engineers are able to achieve a one micron positional accuracy with EDM produced walls as thin as 0.010” (.254mm). If you have an unusual design needing the impressively precise cuts of EDM, give Owens Industries your first call!



Wire Cut Precision Machining

Whether your company is looking for custom tools and dies, to cut titanium products for an aerospace mission or steel tools for a medical facility, Ego is the best company you can choose for wire cut precision machining in the Midwest. With excellent positional accuracies, precision wire cut machining offers exactly measured cuts down to ½ a micron (0.00002”). With different wire diameters available for individual client orders, we can select the proper sized wire for your product, including: 

a. .001” (.0254mm) Diameter Wire
b. .002” (.0508mm) Diameter Wire
c. .006” (.1524mm) Diameter Wire
d. .0015” (.0381mm) Diameter Wire


Although our .006 diameter wire cut machining is most commonly requested by our customers, you can still receive excellent corner radius control with our .0015 diameter wires. While it is convenient to offer .001 wire capabilities to you and your company, we would caution it is extremely expensive and not usually necessary in 99% of orders. If you are looking for other CNC precision machining services like our rotary axial precision wire cut work, they are available for your consideration as well.



From small simple components to large complex tools for plastic molding, stamping, deep drawing, and investment casting, Ego’s CNC machining capabilities are incredible – matching the incredible precision seen in every component and part our professionals produce.


Decades of experience paired with the personal dedication of our CNC machinists and programmers means no project is too big or too difficult for Ego – making us the best possible machining parts producer for manufacturers globalwide. We continue to service our customers all over the world with high precision machining services, including USA, CA, AUS, UK, and more.


It takes an experienced engineering team to properly operate our software and produce high-quality parts—but this difficulty threshold is precisely what sets our CNC Machines and their operators apart. X, A three-dimensional CNC Machine gives us more precise positioning and velocity than is possible with manual machining. X, Y, and Z axis control points provide our technicians with the exact machining capabilities our customers need.  It makes every product we create better than anything else on the market.
