CNC Plastic Machining and Turning Parts Photos
Delrin Machining, CNC Mill Turning
Complex close tolerance configuration required for success of product.
Mill turn completes component in one setup. Accuracy and repeatability of positioning is ensured between ID & OD features.
Acrylic as CNC machined
Customer needs optical finish with low distortion for bubble & liquid visualization
Cast acrylic has the highest light transmittance. Finish as machined with no secondary polishing.
Black Ultem 1000 machining
Double cam design to close tolerances (+/- .001).
Full C axis turning completes component in one setup for feature consistency. Cam profiled. Specialty tooling allows accurate formation of small features.
Direct machine acrylic polishing
Acrylic lens as machined. Customer requires no scratches for viewing through the long end of the part.

Vapor Polished Acrylic 
Flame Polished Cast Acrylic Lens
Military application requires high degree of consistant finish for light lens
Combination of machined finish with flame polish and buffing
Machined Delrin Handles 
Micro CTFE Machining
CTFE valving components require no burrs, close tolerance
Parts produced burr free and complete using special tools running on a swiss turn lathe.
CPVC & Noryl Machining
Noryl valve stem has brittle failure in tension
Suggested material of CPVC solves the problem

Various Acetal Machined Components 
Ultem Plastic Assembly
ESD Ultem component requires consistent black color for optical recongnition
Turning tool testing plus tool maintenance schedule maintains black ESD color for optical readers
HDPE machined components 
Noryl Machining
Black Noryl components used in deep diving application. Customer concerned with potential stress cracking
Proper tool geometry for low stress machining. Annealing cycles to eliminate any future potential cracking and crazing. Components successful in pressure testing.

Polycarbonate machined part 
Polycarbonate machined dilator
Medical Dilator, machined in polycarbonate, and vapor polished.
Polycarbonate Medical Part
Machined Polycarbonate Fitting
Medical device needs near sharp edge (.002-.006) for minimal dead space in blood flow path. No nicks or scratches
Difficult application as processing through vapor polish can scrap part. Special handling procedures meets the customers quality requirements.

PEEK Manifold Machining
Manifolds require instersecting holes with no burrs or debris.
Specialized drills plus machining complete whenever possible produces a consistent part.
30% Carbon Filled Peek
Customer requires oven wagon wheel to be made from 30% Carbon filled Peek billets
Compression molded peek billets are tough on tools. Plastic compatiable coolant with diamond tooling gets the finish needed.

Ultem Machining 
Black Ultem Machined Component
Surgeon's Light has close tolerance helix for light tracking and focusing
Black ultem component turned complete on mill turn lathe. Helix profiled to meet +/- .001 tolerance throughout curve.
Machined polycarbonate coupling. Customer requested flexible coupling for medical application. Part is essentially a spring with little rigidity and C axis machining requirements. The challenge is to remove material in a predetermined fashion to meet the final design without compromising the material. Part must finish complete off of the machine, no secondary operations.
