Swiss Precision Machining (SPM) started out in 1979 in Illinois with three Swiss cam machines, and today it operates more than 90 precision metal fabricating machines.

In the last year, SPM grew from a factory of under 30,000-square-feet to one of 82,000-square-feet in its 37th year of business.

“Our modern facility is ISO 9001:2008 certified as well as meeting ISO spurgear13485 standard for medical devices. We have the most advanced, high speed machinery available, featuring 11 axis, automatic bar loading and CNC control,” SPM reports on its website.

SPM shapes complex parts from stainless steel, titanium, bronze, nitronic 60, brass, aluminum and steel. It is ISO 9001:2008 certified, and for medical devices, it meets the ISO 13485 standard for medical devices.

“Our highly skilled quality control professionals are all trained through a rigorous training program to ensure that they understand the quality expectations of SPM. Our various measurement and inspection devices are meticulously kept to a strict calibration schedule, which is carefully monitored and controlled,” said SPM on its website (

When the company manufactures a gimbal lock plate, SPM meets tolerances of 0.001 of an inch using a CNC Swiss screw machine. The product is manufactured out of 17-4PH H900 stainless steel for the medical industry. The part is used to keep cables separate during robotic surgery.

“We machine a wide range of materials, including aluminum, brass, stainless steel, copper, bronze, and plastic. Specializing in prototype to heavy production volume, we complete all phases of manufacturing on site, including all fixturing and tooling,” SPM said on its website.

cnc-vertical-machining-services-innerSPM’s capabilities include drilling, turning, milling, boring, and knurling and if required broaching, deep hole drilling, hobbing, threading, and slotting without multiple set ups. SPM can handle other tasks, including swaging, lathe work and light assembly, as well as plating, EDM, and coatings.

“Our multi-axis machines with pallet fixturing and CNC control can precisely carry out processes such as drilling, milling, boring, contouring, and counter-boring, while maintaining very tight tolerances,” SPM said on its website.

SPM makes a rotation disk from 416 stainless steel for the archery industry that meets a tolerance of 0.0003 of an inch, or three-ten-thousandths of an inch. The part is machined using a CNC Swiss Screw Machine, as a cam on an archery accessory assembly. The parts were finished by tumbling to a burr-free finish and then heat treated to add strength and to boost their corrosion resistance.
