What to prepare before your press brake arrives

Most first-time buyers worry about the wrong things — the machine, not the doorway, the panel, or the slab it will sit on. Here is what to sort out before the truck is booked, so delivery is a half-day job rather than a two-week problem.

Why plan before the truck shows up

The machine is what everyone thinks about, but the delays come from everything around it: the power in the wall, the doorway, the slab, and the paperwork that clears it into the country. None are hard to fix in principle, but slow and expensive once the truck is in the yard. A few hours of planning before you order turns delivery into a half-day job.

Power: voltage, breaker and the phase question

In the US, three phase supply shows up at a few common voltages. 480V is the most common industrial voltage; 240V and 208V also appear depending on the building. The voltage you have dictates the motor and any transformer the machine needs, so confirm it first.

Breaker sizing is set by the motor rating, not by the tonnage. Take the motor power from the specification, allow for starting current and power factor, and size the circuit so the continuous load stays within the standard North American 80 percent rule for the breaker. Ask the supplier for the motor rating and their recommended breaker; if they cannot give it, treat that as a warning. Do not size the panel from the tonnage and hope.

If your shop only has single phase, that is a separate problem with its own ceiling. Lower tonnage machines can sometimes run on single phase or through a phase converter; larger machines generally cannot. Oursingle phase guide walks through how to work out what your supply will actually support before you commit — worth reading before you decide which machine to order.

Moving it in: weight, rigging and the path

Get two numbers from the supplier before you book anything: the net machine weight and the crated weight. Those drive everything below — forklift capacity, slings, floor load and the doorway. Do not estimate from the tonnage; the real figure is on the packing list.

  • Forklift or rigging. A machine over your forklift's rated capacity at the load centre needs an overhead crane or gantry with rated slings, not a bigger guess. Check the load centre, not just the lift capacity.
  • Doorways and aisles. Measure the crated width and height against every doorway, turn and overhead obstruction on the path from the truck to the final spot. Crated machines are often taller and wider than the bare machine, and a half-inch miss is still a miss.
  • Floor load. Most shop slabs handle a properly distributed machine, but point loads at the feet matter, and very old or cracked slabs are a different conversation. Spread the load with the supplied mounting plates and anchor properly.

Foundation and levelling

Most small and mid-tonnage press brakes do not need a poured foundation — they sit on a level concrete slab and are held down with anchor bolts. The requirement that is easy to skip and expensive to ignore is levelling the machine itself.

An unlevel bed does two things. In the short term it shifts accuracy: the Ram and bed are no longer parallel, so angle and dimension drift along the bend length and crowning works harder to cover it. In the longer term, running a twisted frame accelerates wear on the guides and hydraulics and can permanently stress the bed. Levelling with a precision level, shimming at the feet and anchoring is a half-day task that pays for itself in the first week of correct parts.

Arrival acceptance: a list to work through

Signing the delivery receipt without checking the machine is the most common mistake, because it makes a later damage or non-conformance claim much harder. Work through this in order:

  1. Visual. Inspect the crate and machine for shipping damage before signing, and note any damage on the paperwork.
  2. Hydraulic oil. Confirm the level and no leaks from fittings or seals after the machine has been moved.
  3. CNC power-on. Run the controller self-test and confirm axes home and readouts are sane before any motion.
  4. Empty stroke. Cycle the Ram with no load to confirm approach, bend and return behave with no abnormal sounds.
  5. Trial bend. Run your actual part or a sample and measure angle and key dimensions across several repeats. Repeatability is the number that matters, not a single good part.
  6. Safety devices. Functionally test the light curtain and e-stop — interrupt the beam and confirm the Ram stops, then trip the e-stop and confirm a full stop. Do not assume they work because they are fitted.

Import basics you should know

If this is your first imported machine, a few things are worth understanding before the container leaves the port of loading:

  • Who clears it. A customs broker or freight forwarder usually acts for you and needs the commercial invoice, packing list and any required documentation. The declared machine value is what duty is assessed on, so the paperwork has to be consistent. A broker experienced with industrial machinery avoids the common holds.
  • Container limits. Standard internal dimensions are roughly 19 ft 4 in long, 7 ft 8 in wide and 7 ft 10 in high for a 20 ft dry container, with similar height on a 40 ft box. Long or tall crates may need a flat rack or open-top, which changes cost and handling. Check the crated dimensions against both the container and your doorway.
  • Crating and rust proofing. Require ISPM-15 heat-treated wood for the crate, and specify rust prevention for the ocean leg — VCI paper, desiccant in the crate, and a coating on machined surfaces. Salt air at sea will mark bare steel.

Warranty and after-sales: settle these before you pay

The questions that matter later are the ones to ask before you pay, because once the machine has shipped your leverage drops. None have a single right answer across suppliers, so ask directly and get it in writing:

  • What is the warranty period and what does it cover — parts, labour, travel, or parts only?
  • How does remote support work, and in what time zone? A problem at 7am your time is the middle of the night elsewhere.
  • What is the spare parts situation — are common wear items stocked, and the lead time on the rest?
  • What is the realistic response time for a machine-down situation, and who in your region can do the work?

Questions we get asked

What voltage does a press brake need in the US?

US shops run three phase at a few common voltages, with 480V the most common industrial supply. The voltage you have dictates the motor and any transformer the machine needs. Single phase is a separate question — covered in our single phase guide — and usually only works for lower tonnage machines or via a phase converter. Confirm your actual supply voltage and breaker size on the intended circuit before ordering.

How big a breaker do I need?

It is set by the machine motor rating, not by the tonnage. Take the motor power in kW or HP from the specification, account for starting current and power factor, and size the circuit so the continuous load stays within the North American 80 percent rule for the breaker. Ask the supplier for the motor rating and recommended breaker; if they cannot give it, that is a red flag. Do not guess from the tonnage alone.

Will a standard shipping container fit my machine?

Standard internal container dimensions are roughly 19 ft 4 in long, 7 ft 8 in wide and 7 ft 10 in high for a 20 ft box. Long or tall crates may need a flat rack or open-top rather than a standard dry container, which changes both cost and handling. Get the crated dimensions and weight from the supplier and check them against the container and your doorway before booking freight.

Do I need to pour a special foundation?

Most small and mid-tonnage machines sit on a level concrete slab and are anchored with hold-down bolts. The real requirement is a level, sound slab and proper distribution of the machine weight across its feet. Very old, cracked or uneven slabs, or machines at the heavy end of the range, are worth checking. Levelling the machine itself is non-negotiable — an unlevel bed causes drift and long-term strain.

What should I verify when the machine arrives?

Work through a fixed acceptance list: visual check for shipping damage, hydraulic oil level, CNC power-on self-test, an empty-stroke test, then an actual trial bend where you measure angle and dimension repeatability across several parts, and finally a functional test of the safety devices — light curtain and e-stop. Signing the receipt without this check makes a later damage or non-conformance claim hard.

Who handles customs clearance on an imported machine?

Typically a customs broker or freight forwarder acts for you, and you supply the commercial invoice, packing list and any required documentation. The machine value is what duty is assessed on, so the paperwork has to be consistent. If you have never imported machinery, a broker experienced with industrial equipment avoids the common holds. Settle this before the container leaves the port of loading, not after it lands.
