1. CNC Door Fabrication Workflow
1.1. Design and Planning
The first step in making CNC doors is planning. This step decides how the door will look and work. A digital plan is made using CAD software. This software shows the door’s size, patterns, and details before making it. Keeping designs simple saves time and avoids mistakes. Removing extra features also makes the process faster.
To get good results, keep tolerances correct. This helps the door fit well and balances cost and quality. Picking the right tools is also key. Tools for fast cutting or smart paths work better and last longer. Careful planning makes the process smooth and accurate.
Tip: Always check your design carefully before moving forward. A small mistake in the plan can cause big problems later.
1.2. Material Selection
-
Board or Panel Choice: The door core and decorative panels can be solid wood, plywood, MDF or other engineered materials. CNC machines handle various densities – from softwoods for fast roughing to hardwoods for elegant solid doors.
-
Fixture Setup: Doors or panels are clamped on tables (vacuum or mechanical clamps) to secure them during milling and drilling.

1.3. CNC Cutting and Profiling
-
Panel Cutting: A CNC wood router (often 3- or 5-axis) cuts door blanks to shape and routs panel recesses. High-speed end mills can shape door outlines with smooth edges. CNC routers excel at “high-speed door milling” – carving out material rapidly with precise feeds.
-
Edge Profiling: Decoratively shaped bit profiles add chamfers or ogee edges to door faces. These features are fully programmable for consistency across batches.
-
Custom Inlets: Spaces for glass inserts or pre-hung frame fittings are precisely milled.
1.4. Joinery and Hardware Grooves
1.4.1. Mortises and Dovetails
For frame-and-panel doors, CNC machines cut mortises (e.g. tenon slots) and dowel holes with tight fits.
1.4.2. Lock and Hinge Drilling
A door drill machine bores holes for handles, locks, and hinges. CNC accuracy is critical – installers rely on “precise holes for door locks and handles”. Modern CNC door and lock drill machines often use multi-spindle heads to punch all lockset and hinge holes in one cycle.
Automated 6-sided drilling machine can simultaneously process both door faces, edges, and ends. These rigs feature multiple servo-driven spindles so that dozens of lock and hinge holes are drilled per cycle (see Figure below).
1.5. Surface Preparation and Finishing
Surface preparation and finishing are the last steps in making CNC doors. These steps make the door look nice and protect it from damage. Good preparation helps the finish stick well and last longer.
Start by sanding the door to remove rough spots. CNC machines leave little roughness, but sanding makes the surface smooth. Use fine wide belt sanding machine for the best results. After sanding, clean the door to remove dust. A clean surface is important for a good finish.
Next, apply a primer to seal the wood and create a smooth base. Primers also protect the wood from moisture. Once the primer is dry, add the topcoat. Pick a finish that matches the door’s use. Polyurethane is great for outdoor doors. Water-based finishes are better for indoor doors because they dry fast and have low odor.
Tip: Test the finish on a small hidden spot first. This ensures the color and texture are what you want.
CNC machines can also add detailed designs like engravings or patterns. You can highlight these with stains or paints for a unique look. By learning surface preparation and finishing, you can make doors that are both useful and beautiful.

2.1.1. Six-Side CNC Drill Machines: Features and Benefits
Bestin CNC (and similar suppliers) offer specialized Six-sided CNC door drilling machines. These robust machines are built for high throughput door production. Key features include:
-
Six-sided access: Hydraulic or linear lifters flip the door blank so that both faces and all four edges are drilled or milled in one setup. This eliminates manual re-fixturing.
-
Multi-spindle drilling heads: Multiple drills (sometimes dozens of spindles) operate in parallel. A multi-spindle router head can cut hinge mortises, lock pockets, and edge holes simultaneously. For example, some machines have “2 drill set 30 motors” to drill up to 30 holes at once.
-
Heavy-duty construction: Precision linear guides (X/Y gantry rails, Z-ball screws) ensure micron-level repeatability. High-quality steel frames and imported drill bits improve durability.
-
Servo-driven motion: High-torque servo motors with reducers enable high-speed door milling and drilling across wide panels (virtually “no limit to board width”). Automatic lubrication and brush dust extraction maintain reliability in 24/7 production.
2.1.2. CNC Door and Lock Drilling
CNC Door Drilling Machines are specifically applied to hardware preparation in door manufacturing. Typical use cases:
- Lockset and Handle Holes: Drilling door faces and edges to fit mortise locks, cylinder holes, and knobs. CNC mills the precise pocket shape and through-holes for each lock model.
- Hinge Drilling: Cutting hinge mortise cavities on the door edge or face. A high-end CNC drill machine can rout multiple hinge pockets with exact depth control.
2.2. Router Bits and Cutting Tools
Router bits and cutting tools are important for shaping door designs. These tools cut materials and add patterns. Straight bits make clean cuts, while V-groove bits create designs. Good tools last longer and give better results.
2.3. Dust Collection Systems
Dust Collection Systems keep your workspace clean and safe. CNC machines make a lot of dust, which can harm machines and air quality. A dust system removes dirt, protects tools, and keeps the air fresh.
2.4. CAD/CAM Software
CAD/CAM software is very important for making CNC doors. It helps you plan, design, and run tasks easily. CAD (Computer-Aided Design) software creates detailed door models. These models include sizes, patterns, and complex designs. CAM (Computer-Aided Manufacturing) software turns these models into instructions for machines. This ensures accurate and smooth production.
2.5. Safety Gear
