American Precision Services, Inc.

A customer in the steel producing industry contracted us at American Precision to manufacture the bearing housings highlighted here. Utilizing 304 stainless steel, our CNC lathe, CNC mill, and welding equipment were employed to carry out production, performing precision milling, drilling, tapping, and fabricating processes to form the parts to customer requirements. The tightest tolerance of ± 0.1 mm was achieved during production. The machined housings were deburred for smoothing and cleaning. The bearings housings were then pressure tested, and thoroughly inspected with dimensional, visual, and magnetic particle inspection methods to ensure quality. Overall part dimensions were 263mm in length, 246mm in width, and 104 mm in height, exhibiting a raw machined finish. Turnaround time for this project was 60 days, and included the fabrication 112 units for the customer with shipping to Burns Harbor, IN.

A customer in the steel and mining industry took advantage of our recognized manufacturing services, hiring us at American Precision Services to complete the custom fabrication of the carriage base highlighted here. Utilizing steel in beam, bar, and plate form, our advanced horizontal boring mill equipment was employed for manufacturing. Certified welding and precision milling processes including drilling, boring, and tapping were carried out to create the base as specified in the customer supplied 2D CAD drawings. The parts were stress relieved to combat instability and distortion, assembled as required, and painted with primer. The tightest tolerance met was ± 164”, with finished overall dimensions being 5'-8½" in length by 4'-¾" in width. Quality and accuracy were ensured with thorough dimensional and visual inspections. Turnaround time for this project was 60 days, shipping the base to the customer in Chicago, IL. For more information about this custom carriage base fabrication, or our other experienced fabrication and precision machining capabilities please see the table below or contact us directly.

A customer in the steel industry contracted us at American Precision Services to create the liners as highlighted below. Utilizing our advanced CNC milling machine, magnesium bronze material was manipulated to meet the specified contours, with the completed unit measuring 8’5” in length, 5” in width, and a height of 0.75”. The tightest tolerances of +0.001-0” was met during production. Flame hardening was also employed for increased wear resistance and less distortion, and the unit was also deburred to smooth and remove manufacturing debris. The liner was left with a raw finish, and received comprehensive inspections including visual, dimensional, and magnetic particle inspections to ensure quality and integrity. Thirteen liners were produced within a turnaround time of 30 days, shipped to the customer in East Chicago, IN.

In order to bring a failed single stage vertical lift pump to OEM tolerances, a customer in the pump industry contracted us at American Precision Services to inspect and repair the unit. After inspecting the pump to determine the actual deficiencies, our team reverse engineered the necessary components and drafted them in our 3D modeling software. This capability allowed us to virtually assemble the unit to verify form, fit, and function. Utilizing our CNC lathes, CNC mills, grinding machines, vertical boring mills, horizontal bar mills, blasting equipment, and dynamic balancing equipment, a range of materials were manipulated to create the pump’s new parts including 420 stainless steel, A36 steel, 4150HT steel, and 932 bronze. All of which were machined to tightest tolerance of ± 0.001", with up to a 32 RMS surface finish. The pump was assembled on site, with overall measurements of 30' in length and 60" in diameter and an assembled weight of 22, 000 lbs. This project was completed in a turnaround time of 60 days, shipped to the customer in East Chicago, IN as agreed. For more details about this single stage vertical lift pump inspection and repair project, or more about our repair and custom manufacturing capabilities please see the table below or contact us directly.

Alongside our recognized machining and manufacturing capabilities, customers trust us at American Precision Services with advanced repair services, as outlined in the project highlighted here. A customer in the water pump industry contracted us to service a six stage boiler feed water pump which had failed inspection. After careful inspection by our experts to determine necessary repairs, we reverse engineered the required components, drafting them in 3D modeling software. The software was used to virtually assemble the total unit, confirming clearances, fits, and sizes. A range of equipment was employed for the custom manufacturing process including CNC lathes, CNC mills, grinding machines, vertical boring mills, horizontal bar mills, dynamic balancing equipment and assembly fixtures. The parts were composed of 420 stainless steel, 410 stainless steel, CA-6NM alloy, 4150 HT steel, and 932 bronze all machined to tolerances of ±0.001". Functionality tests, visual and dimensional inspections were carried out to verify accuracy. Overall dimensions of the finished pump were 84" in length by 26" in diameter, with a weight of 2, 200 lbs. Features of the upgraded water pump include a capacity of 1, 400 gpm, 3, 600 rpm speed, 250°F liquid temperature, discharge pressure of 1, 500 psig, and total head of 3, 588 ft. Turnaround time for this project was 120 days, shipped to the customer in East Chicago, IN.

At American Precision Services we were contracted by a customer in the Nash pump industry to provide custom wire manufacturing services. The project required the fabrication of expanding outer flange castings as highlighted below. Employing our CNC lathe and mill, we implemented rough and finish turning processes, along with milling techniques including drilling and tapping to meet the specifications as outlined in the supplied 2D CAD drawings. The units were then cleaned and smoothed with a deburring process. Finished dimensions for the castings were 21.985” in diameter, and 1.594” in height which was verified with comprehensive visual and dimensional inspections. Turnaround time for this project was 2 weeks, with 20 units fabricated for the customer and shipped to Birmingham, AL.
