CNC Machining Laser Marking & Laser Welding Wire EDM Metal Stamping Induction & Torch Brazing Bead Blasting Surface Grinding Metal Polishing Secondary Services

CNC Machining Services

JNS Industries specializes in CNC milling, turning and screw machining to produce high precision medical, dental and surgical parts. Our Ontario, CA facility houses 3- and 4-axis CNC milling centers with auto tool changers and 2-axis CNC lathes with bar feeder equipment that reduce downtime for increased production. We commonly machine a variety of stainless steel from billets, forgings and bar stock.

Each CNC machining center is directly wired to the computer which is equipped with CAM software such as Feature cam. The geometry is converted into the tool path and is directly downloaded to the machines to avoid any human error. The machining centers and software are capable of generating G codes to perform either 2D or 3D ...


Wire EDM Services

JNS Industries provides wire EDM services for close tolerance machining of parts required for the medical, dental and surgical industries. For short to medium production volumes, the submerged EDM cutting process is capable of cutting any conductive material regardless of the material’s hardness.

From a concept to a finished product, the employees at our Ontario, CA facility have the experience and knowledge to advise on each step of product’s life cycle. We use 3D modeling and CAD/CAM programming for rapid prototyping to ensure all design requirements are met prior to full production.

Laser Marking & Laser Welding

Laser Marking & Laser Welding Services

Laser Welding Services
JNS Industries provides laser welding services, including seam and spot welding, for filling voids and porosity in casting and forging materials. With regulated heat, our laser welder is capable of delivering spot of varying sizes from 0.001" to 0.015" in diameter. The clean and fast welds are superior to brazing with production costs comparable to other joining methods. Laser welding can fuse similar or dissimilar material, such as stainless steel and titanium, in an inert (Argon) atmosphere or in the presence of oxygen.
