24 real Projects's CNC Precision parts, six industries, one shop
Each card is a genuine sample cnc parts we've produced — not a placeholder. Filter by industry, check the material and process, and use it as a starting point for your own drawing.
Drone Precision Frames & Mounts
Featherweight airframe brackets and motor mounts machined from titanium for endurance drones, holding tight positional tolerance so rotor assemblies stay balanced in flight.
Engine Mounts & Housings
Hard-anodized housings that isolate avionics packages from engine heat and vibration, milled with finned surfaces for passive cooling and integrated EMI shielding.
Flight Control Actuator Housings & Linkages
Passivated stainless linkages and actuator housings rated to 10,000 psi for hydraulic flight-control systems, finished to resist corrosion through high-altitude, high-cycle service.
Wing Ribs & Fuselage Structural Brackets
Deep-pocketed structural ribs and brackets machined from Inconel 718, holding wall sections under a millimeter while retaining the load-bearing strength airframe structures demand.
Valve Bodies & Fuel System Components
Titanium valve bodies machined with a 12-port manifold pattern for fuel and pneumatic distribution systems, engineered for weight savings without sacrificing pressure integrity.
Landing Gear Struts & Actuator Components
Swiss-turned struts and actuator pins for landing gear assemblies, held to ±0.005mm stacking tolerance so multi-part gear sets fit and cycle without play.
Transmission Gear Shafts
Motorsport-spec gear shafts turned and milled from 2618 aluminum to cut rotating mass, holding spline accuracy that keeps gear engagement crisp through repeated high-RPM shifts.
Suspension Control Arms
Forged-profile control arms machined from 6061 aluminum for EV suspension systems, cutting unsprung weight while holding the stiffness needed for consistent wheel geometry.
Brake Calipers
Titanium brake calipers turned for track applications, holding piston-bore roundness within tight limits so pad pressure stays even under repeated heavy braking.
Wheel Hub
Heavy-duty wheel hubs milled from 4140 steel and black-oxide finished for corrosion resistance, holding bearing-bore concentricity for smooth, vibration-free rotation.
Dental Implant Abutments
Swiss-turned implant abutments in 17-4 stainless, polished to a sterilizable surface finish and held to micron-level concentricity for a precise prosthetic fit.
Hip Joint Components
Milled PEEK Optima components for hip implant systems, machined with a porous surface texture that supports bone in-growth for long-term implant stability.
Orthopedic Bone Screws
Self-tapping titanium bone screws machined on 5-axis equipment, holding thread profile and shank concentricity within surgical tolerances for reliable fixation.
Surgical Forceps
Precision-milled forceps handles and jaws in medical-grade 6061 aluminum, finished to withstand repeated sterilization cycles and light enough for extended use in the OR.
Robot Gearbox Housing
5-axis machined gearbox housings for 6-axis robot arms, holding bore-to-bore alignment within ±0.01mm so gear trains run quiet and backlash-free.
Precision Gear Shaft
Stainless drive shafts with a milled serrated surface for positive torque transfer in robotic joints, held to tight roundness for smooth rotation at speed.
Robot End-Effector Mount Plate
Powder-coated A36 steel mounting plates that interface end-effectors to robot wrists, milled flat and square so tooling stays aligned across tool changes.
Robot Arm Joint Housing
Turned aluminum joint housings sealed to IP67, protecting motor encoders and wiring in robot arms operating in dusty or wash-down manufacturing environments.
CPU Heatsink
Copper heatsinks milled with 0.5mm fin walls for maximum surface area in a compact footprint, machined to hold contact-face flatness within thermal-interface tolerance.
Aluminum Enclosure
Black-anodized 6063 aluminum enclosures milled for EMI shielding and heat dissipation, protecting sensitive electronics in industrial and outdoor installations.
Ball Valve Body
316 stainless valve bodies turned to 2-inch NPT thread standard, holding bore roundness for a reliable seal in high-pressure industrial fluid systems.
Helical Gear
4140 steel helical gears cut to AGMA 10 quality for quiet, high-load gearbox performance in industrial drive systems.
Hydraulic Manifold
5-axis machined 8-port manifolds that consolidate hydraulic circuits into a single aluminum block, cutting leak points versus fitted tube assemblies.
Centrifugal Impeller
300mm bronze impellers machined on 5-axis equipment for marine and industrial pumps, with blade profiles held to close tolerance for consistent flow and efficiency.
