  Wood router classes and what each one is for

Most quotes go wrong before anyone opens a spreadsheet. A buyer asks for a cnc machine for wood price, then describes the machine instead of the part. What matters is the cut: material, sheet size, depth of cut in one pass, edge quality, and how many identical pieces you run per week.

Write the part family down first. Panel furniture uses 18 mm MDF or particleboard with a 6 mm compression bit. Sign work uses 12–20 mm acrylic or PVC. Musical instrument bodies and chair frames use hardwood at 30–60 mm thickness with a ball nose. Each group needs a different spindle and a different fixture.

Depth of cut per pass sets spindle power. Softwood and MDF cut at 6–10 mm per pass on a 3 kW spindle with a 6 mm bit. Hardwood and plywood usually run 3–6 mm per pass. If your part needs 18 mm in one pass, you are in a different machine class.

Count the axes you truly need. A flat panel is a 3-axis job. A shaped chair leg, a curved handrail, or a carved mold needs 4 or 5 axes, or a fixture that lets you index the part by hand. Manual indexing is cheap and slow. It is often the right answer for ten parts.

Bed size is the first hard number. A 600 × 900 mm bed handles signs, guitar bodies, and small fixtures. A 1,300 × 2,500 mm bed handles full 4 × 8 ft sheets. The step between them is not linear: the frame gets heavier, the gantry beam gets longer, and the rails need more support to hold the same deflection.

Measure the largest part you will run in the next two years, then add 100 mm on each side for clamping. Buying a bed that is 30% larger than needed costs money twice, once at purchase and again in floor space and warm-up time.

Spindle power is the second hard number. A 1.5–2.2 kW air-cooled spindle cuts signs, foam, and thin plywood. A 3–4.5 kW spindle handles 18 mm particleboard and MDF at production feed rates. A 6–9 kW spindle is for deep hardwood cuts, dense composites, and heavy nesting.

Air-cooled spindles are simpler and cheaper. Water-cooled spindles hold lower bearing temperature and are quieter, but they add a chiller and a maintenance item. For a shop running eight hours a day, the chiller is usually worth it.

Motion hardware decides accuracy more than the control brand does. Linear profile rails with a preload class hold better than round rails over a long gantry. Ball screws are better than rack and pinion for short axes; rack and pinion is normal on a 2,500 mm axis because a long ball screw whips at speed.

Wood routing produces two waste streams: chips and fine dust. A dust shoe around the spindle with a 100 mm hose captures most chips. Fine dust needs a cyclone or a cartridge extractor. If the extractor is undersized, dust settles in the rail covers and the machine starts losing position within months.

Hold-down choice changes cycle time. A vacuum table with a 5.5–7.5 kW pump holds full sheets and lets you nest parts edge to edge. Mechanical clamps or screws are cheaper but need tabs and a trimming pass. Pod and rail systems suit window frames and long parts.

Fire risk is real on MDF and hardwood dust. Keep the extraction path grounded, empty the bin before it is full, and never leave a warm spindle parked over a pile of dust at the end of a shift. A small compressed-air blow-off helps clear pockets.

Safety is a cost line, not an afterthought. An enclosure with interlocked doors, a pressure-sensitive bumper, and a physical emergency stop on the gantry side are common requirements in Europe and North America. Add them at order time.

Tooling is where the yearly money goes. A 6 mm compression bit for double-sided melamine costs far less than the machine, but a busy nesting shop replaces bits every 40–80 cutting hours. Add up-cut, down-cut, compression, ball nose, V-groove, and drill bits. A modest starter set of 15–25 cutters is normal.

Collets and holders wear too. Keep a spare set of ER20 or ER32 collets and replace any collet that shows a score line. A worn collet lets the bit slip, and a slipped bit breaks on the first heavy pass.

CAM software has two costs: the license and the learning time. Panel nesting packages handle sheet optimization and labeling. General CAM handles 3D relief carving and guitar bodies. Post-processors must match the control on the machine, or you will hand-edit G-code every job.

The control decides who can run the machine. A basic DSP handset is cheap and fine for signs. A PC-based control with a tool library, feed override, and simulation shortens setup for mixed work. Ask what happens when a job stops halfway: can the operator resume from a line number?

Bring one real part file to the demo. Watch the whole chain: import, toolpath, post, dry run, cut. That single test tells you more than a spec sheet.

A machine price is a one-time number. Cost per finished panel is the number that decides whether the purchase works. Divide the machine price over its expected service life, then add tooling, extraction power, spindle chiller power, labor for setup, and scrap rate.

Setup time dominates short runs. A job of twenty panels may spend more spindle hours loading and zeroing than cutting. Vacuum tables with a defined datum corner cut zeroing to one minute. Clamped jobs can take ten. On small batches, that gap decides the schedule.

Scrap rate follows the hold-down and the toolpath. Thin plywood with an up-cut bit and a weak vacuum tears out on the last pass. Use the right bit, leave an onion skin, and run a finishing pass. A 2% scrap rate on expensive hardwood is a real cost line.

If wood is only part of your product, do not buy a router for a few parts. A metal machining shop with 3-axis and 5-axis capacity can cut wood fixtures, jigs, molds, and tooling boards alongside the metal parts, and you skip the floor space, the dust system, and the operator training.

GreatLight runs 127 high-precision CNC machines, including 16 simultaneous 5-axis centers and 27 three-axis machines, with a 4,000 mm maximum processing size. Tolerance holds at ±0.005 mm and surface finish is available from Ra 0.2–0.8 μm on request. That covers wood pattern work, tooling board, and fixtures without a dedicated router purchase.
