How to choose door production machinery

Choose door production machinery by deciding which of the three jobs in a door plant you are mechanising first: the leaf, the hardware seats, or the frame. Most door workshops in Georgia start with the leaf, because leaf sizing is the operation that consumes the most operator time and where a wrong cut scraps the most expensive component.

Sizing the leaf

Leaf sizing machines are the largest group in this category, with 8 machines listed. The dividing line inside that group is whether the machine only sizes the leaf or also machines the hardware. A manual sizing machine trims the leaf to width and length and cuts nothing else. The NC-controlled RIPPER family sizes and edge-mills, and the KK versions add lock, handle and recess machining on the same pass. The twin-bridge and servo CNC versions exist for plants where cycle time per door, rather than accuracy, is the constraint. Frame, jamb and architrave components are narrow parts and are handled by the KS model rather than by the leaf machines.

Lock, handle and hinge seats

Lock and hinge mortising machines are the answer when leaves arrive already sized – from a supplier or from a machine that does not pocket hardware. The 3 mortising machines here cut lock seats, faceplate recesses and hinge seats, and the specification that separates them is whether the machine cuts locks only or locks, faceplates and hinges together at one clamping. A workshop that already runs a RIPPER KK or a CNC RIPPER usually does not need a separate mortising machine.

Making the frame

Frame production is a separate machine group from the leaf. Frame stock is profiled by through-feed moulding, and the FR-532 covers that operation. Assembling the four profiled pieces into a finished frame is what the NETMAK NKM 240 CNC frame assembly machine does. A door plant that buys leaf machines but subcontracts frames postpones both of these; a plant that wants to control the whole door buys the profiling and the assembly machine together.

Power supply, space and extraction

Door production machinery is three-phase 400 V equipment, and the installed power on this class of machine is substantial – the CNC leaf machines and the frame moulder carry multiple spindle motors plus servo drives. Confirm the incoming supply and breaker rating with an electrician before ordering, and plan compressed air as well, because clamping on these machines is pneumatic. Space is dictated by door length: allow the full leaf length clear at infeed and outfeed plus room for a stack of leaves on each side. All of this machinery produces chip and dust at every cutting head, so extraction ducting must reach each head, not only the main cabinet.

What the quoted price depends on

The price of door production machinery is driven by the control system and the number of working units. PLC-controlled machines sit below servo CNC machines; a single bridge sits below a twin bridge; a machine that only sizes sits below one that also pockets locks, handles and hinges. Add to that the tooling package – cutters, saw blades, lock and hinge templates – which is quoted separately, plus delivery to site, installation and operator training. Send your leaf sizes, frame profiles and the lock and hinge hardware you fit, and we will quote a machine specified against them.
