• C axis with RV gearbox pivoting 360° — approach from any direction without repositioning the door — the CNC centre for milling hinge and lock recesses on doors has a C axis with a robotic-type RV gearbox that rotates the milling head 360° horizontally and automatically switches the approach direction of the cutter. This configuration allows the flat hinge recess to be milled from the exact direction required for a recess with smooth depth and walls, without turning or repositioning the door. The RV gearbox — used in the joints of industrial robots — ensures stable precision and a long service life under repeated switching in intensive production.

• 4 horizontal spindles + 2 vertical — 6 milling heads in a single piece of equipment — the CNC centre for milling hinge and lock recesses on doors has 4 horizontal spindles (7,5 kW + 2 × 2,2 kW) and 2 vertical HQD spindles of 6 kW, totalling 6 active heads in a single machine with a total power of 15 kW+. The horizontal spindles cut the hinge recesses on the door edge and the lock-body hole, and the vertical HQD spindles perform the drilling and milling required on the front faces of the door. The combination of 6 heads eliminates 3–4 manual passes or passes on separate machines.

• Power 15kW+, 18,000 rpm speed — aggressive milling in solid wood and fire-rated doors — the CNC centre for milling hinge and lock recesses on doors is designed for machining solid-wood doors (oak, beech, pine) and fire-rated doors with a compact core, materials that require far greater milling force than chipboard or MDF. The maximum speed of 18,000 rpm ensures clean recess surfaces without fibre tear-out, critical for fitting screw-mounted hinges without additional finishing operations.

• 1,000 W servo with brake on the X, Y, Z axes — precision and head protection — the CNC centre for milling hinge and lock recesses on doors uses 1,000 W servo motors with an integrated brake function on all three main axes. The brake instantly stops head movement at the end of the cycle or at an emergency stop, protecting the cutters and milling heads from damage due to inertia. The 1,000 W servos (superior to the 850 W servos of simpler models) provide the feed force needed for aggressive milling in solid wood at processing speeds of up to 80 m/min.

• Taiwan #30 square rails on all axes — superior guidance for milling with lateral load — the CNC centre for milling hinge and lock recesses on doors uses Taiwan 30 mm square rails (compared with the round 20–25 mm rails of standard routers), the configuration that withstands the lateral loads generated by aggressive milling on the door edge. When milling the hinge recess on the edge, the milling force has a significant lateral component — the #30 rails of the CNC centre for milling hinge and lock recesses on doors absorb this load without deflections that would affect the depth or alignment of the recess.

• Dedicated CAM software with predefined shapes for locks and hinges — no programmers — the CNC centre for milling hinge and lock recesses on doors has an integrated professional control system with CAM software specific to doors, featuring a library of predefined shapes for all standard types of locks and hinges. The operator selects the hardware type, adjusts the dimensions directly and the machine automatically generates the milling programme — without CNC programming knowledge, without external files, without a long setup time between different orders.

• Pneumatic clamps with a door-dedicated pressing plate + durable PVC table — secure clamping, protected surface — the CNC centre for milling hinge and lock recesses on doors clamps the door onto the high-strength PVC worktable by means of adjustable pneumatic clamps with a pressing plate specially designed for wooden doors. The PVC table does not scratch the surface of the door in contact with the table, and the pneumatic clamps do not require a vacuum pump, saving energy and eliminating the risk of the door coming loose during a loss of vacuum pressure.

• Integrated oil-water separator + automatic lubrication — minimal maintenance, high reliability — the CNC centre for milling hinge and lock recesses on doors has an integrated oil-water separator that protects the pneumatic system and internal components from water vapour in the compressed air, extending the service life of the components in continuous production. The automatic lubrication system eliminates the need for daily manual lubrication of the guides and racks.

• 60-month UZINEX warranty — spare parts in stock in Iasi, national technical support within 24–48 hours, transport, installation and commissioning included.
