Parts Manufacturing Portfolio - Prototype Machining

CNC machining services for optics. Prototype of night vision binoculars.

MACHINING SERVICES OPTICS: Customer-supplied design, constructed from a combination of aluminum and plastic materials. All parts machined from solids before being cast for production. All aluminum parts machined to .001 total tolerance after plating. Plastic components machined with ultra-fine thread design and close tolerance drops to maintain lens focus. This short run (20 units) was developed in under eight weeks with a total of 13 different components.

RAPID PROTOTYPE OPTICAL ASSEMBLY: One-off optical assembly machined from solid aluminum. Numerous .001 total tolerances after plating with a .0012 perpendicularity from base surface to lens mount on a 12 x 12 x 11.5” total assembly size.

Machine shop prototype of teflon mixer. Part fabricated by TPM, a NH machine shop.

PROTOTYPE TEFLON MIXER: Teflon static mixer element 4-axis machined from solid stock. Although tight tolerances were not an issue, optimum finish with lack of rigidity were. Part size approx. 16 x 2.5” diameter with .100 thick web between elements.

Machine shop prototype propeller in aluminum. From TPM north of Boston in NH

PROTOTYPE PROPELLER MOCK UP: Scaled aluminum propeller mock-up machined from solid stock with a final fin thickness of .042.

Plastic machining, aluminum battery housing by NH machine shop True Position Machine

PLASTIC MACHINING BATTERY HOUSING: Glass-filled plastic housings machined from solid stock. Surfacing done inside and out with a max wall thickness of .04 on top left battery housing. 16 finish required on all surfaces.

Machine shop producing optic lens components in NH, north of Boston, MA

MACHINING OPTIC LENS COMPONENTS: Optic lens components cut from solid stock with arm perpendicularity of .001 to base. Tolerances of .001 total apply after plating. Black hard coat and black anodize shown here with a final machined surface after plating for electrical purposes.
