At Niagara Precision we provide precision CNC machining services to customers in a wide range of industries. Here are just a few examples of the innovative solutions and value added products and services that we deliver every day.

At Niagara Precision, we specialize in precision CNC machining and assembly for customers in a wide range of industries. We were contracted by a manufacturer of commercial furnaces to develop a small-scale water-cooled oxygen injection lance, which was to be used in an experimental smelter. The engineering efforts included complete design and product development including feasibility studies. Because the lance was to be used in the high temperature environment of a smelter, it featured a complex water jacket system.

Composed of stainless steel and copper, components which we machined on our CNC lathe, and 4-axis CNC mill, this allowed us to meet tolerances of ±.001″. After dimensional inspections, the machined components were assembled and brazed. The finished lance had dimensions 24″ in length, 6″ in width and height, and weighed 201 lbs.

Products such as this injector lance are usually produced in Europe, because of our flexible and complete capabilities, we were able to provide this customer with a single source solution, produced domestically. To learn more about this project, see the table below or contact us directly.

As a full service provider of precision machined components, Niagara Precision provides customers with a single source solution to their custom manufacturing needs. We were contracted by a manufacturer of boilers, to fabricate a die that would be used to bend steel boiler tubes. The customer supplied us with specifications, which we used to engineer the final design. Composed of 4340 steel, the finished die featured dimensions 6″ in length, height, and thickness, with machined tolerances of ±.001″, in addition, it also required a polished finish. After machining and dimensional inspections, the die was then heat treated with a nitriding process, before receiving a surface coating. Although this project is outside of our normal scope of work, we were still able to complete the entire job is just 8 weeks. For more information see the table below or contact us directly.

Niagara Precision was approached by a producer of food products to precision CNC machine a rotary impression die, which was designed for use in a cereal manufacturing process. Composed of food grade stainless steel, the specifications required extremely tight tolerances. Final dimensions had to meet tolerances of ±.001″, in addition, the finished piece had to pass functionality testing. Manufacturing required extensive CNC milling and turning and drilling, as well as assembly and fitting of the finished components. Through the manufacturing and assembly process, all parts were subject to stringent quality measures including comprehensive dimensional testing. Completed in only 8 weeks, this product met all of the customer specification, for precision and quality,

The project highlighted here represents a large scale machining effort for Niagara Precision. These doors were designed for use on the front of an X-ray radiation containment structure, and were ultimately installed at a nuclear power facility in Ontario, Canada. From the customer’s specifications, we developed a design and conducted feasibility studies to ensure that the finished product would perform exactly as expected. Composed entirely of structural steel, the design also included a low speed drive mechanism to operate the two 19,000 lb. doors. Each door had a final dimension of 10’ in width, 20’ in length, and 3” thick, which had to be manufactured to tolerances of ±.005”. The machining, all of which was complete in-house, consisted of CNC turning and milling, as well as the use of our boring mill. After extensive dimension and visual inspections the doors were painted, assembled, and put through vigorous functionality testing. This project was designed, manufactured and delivered in 5 months.

At Niagara Precision we specialize in tight tolerance, precision CNC machining. These valve stems are used with extreme condition valves for oil, gas and chemical industry applications. Composed of Inconel, an exotic alloy suited for high temperature applications, the parts also required very tight tolerance machining as well as a high finish. Inconel being an extremely hard material to machine, this project required specialized tooling for the CNC turning needed to manufacture this product. Raw stock was saw cut before moving onto machining, after turning and milling, all parts were deburred before final inspection. At Niagara Precision we take quality seriously, our facility is ISO 9001:2015 certified, as a result everything that we manufacture is subject to stringent quality measures. Parts vary in length from 6″ to 15″, diameters of 3/8″ to 4″, and weighing ¼ to 10 lbs. each. We currently manufacture large quantities of these pieces per year, shipping to this customer in Southern Ontario with lead times of 1 day to 4 weeks.

We were recently approached by a customer servicing the oil, gas, and chemical industries, who needed a series of products machined from various exotic metals. The bodies and flanges they required were designed for use in extreme conditions, and would utilize material such as Inconel 718, Incoloy 800, Hastelloy C276, Duplex 2205, and titanium. All of these alloys exhibit different machining characteristics, but all required tight tolerances and high finishes.

Machining required precision CNC milling and turning, as well as deburring. Dimensions varied, from 3″ to 8″ in thickness, 3″ to 16″ in diameter, 11 to 200 lbs. Parts were also subject to stringent quality measures, in line with our status as an ISO 9001:2015 certified company. We currently manufacture over 1,000 of these items per year for this customer in Ontario, Canada.
