Foam Boring Machine with 45-80 mm Adjustable Hole Diameter and 2300 mm Boring Length

The TDP-52 is a horizontal cylinder foam boring machine with a 230 r/min main shaft. Hole diameter is adjustable from 45 mm to 80 mm, boring length is 2300 mm, motor power is 1.5 kW, machine weight is 800 kg and overall dimension is 6000*1500*1800 mm. The machine is CE certified.

The hole has to match the shaft. A mandrel that is loose in an oversize bore lets the block rock while it is peeled, and an undersize bore will not take the shaft at all. Shafts are not standard across a plant, so the machine has to cover the range without a second unit.

The TDP-52 covers 45-80 mm with interchangeable cutter heads and holds a 230 r/min spindle speed through the cut. That combination keeps the bore round and the wall clean across the whole range, including at the larger head sizes where a slower spindle would tear the foam.

• Model: TDP-52

• Spindle speed: 230 r/min
• Boring length: 2300 mm
• Motor power: 1.5 kW
• Weight: 800 kg

1. Pick the head. Select the cutter head for the shaft diameter being used.
2. Seat it fully. Check the head is seated and locked before the spindle starts.
3. Clamp the block. Square the block to the spindle and lock the stop.
4. Bore a test hole. Cut a test block and measure the hole at both ends.
5. Check the fit. Slide the shaft in; the fit should be firm without forcing.
6. Run the batch. Keep the same head for the batch to hold the tolerance.

Keep one head per shaft size and label it. Mixing heads between batches is the most common reason two blocks from the same order bore differently.

Foam does not cut like wood. The cutter shears the cell structure, so the wall finish depends on spindle speed and feed rate working together. At 230 r/min with a matched feed, the wall comes out clean; slow the spindle and the cutter starts to tear instead of shear.

Hole diameter is a head question, not a spindle question. Each head is set for a shaft size, so the tolerance is held by the head and the operator only has to seat it properly and keep it sharp.

The third factor is clamping. Foam is soft enough that a badly clamped block deforms under the cutter, which shows up as an oval hole. Squaring the block against the stop is what keeps the bore round.

• Speed: 230 r/min shears the foam cleanly.
• Range: 45-80 mm without a second machine.
• Tolerance: held by the cutter head and proper clamping.

• 2300 mm stroke: a full cylinder block is bored in one continuous pass.
• 45-80 mm holes: the cutter head is changed to suit the shaft being inserted.
• 230 r/min spindle: a steady cut through soft and medium density PU foam.
• 1.5 kW motor: low running cost on a single-phase-friendly drive.
• Horizontal layout: a low, compact frame that fits beside the peeling machine.
• Peeling line match: the bore is aligned with the peeler mandrel, so the block loads straight on.
• CE certified: export-ready guarding and electrics.

• Cylinder foam lines: centre holes bored after the block is poured.
• Peeling stations: pre-processing ahead of the peeling machine.
• Mattress foam plants: blocks prepared for shaft insertion.
• Sponge converting: round blocks bored before slicing.
• Foam recycling: reclaimed cylinders prepared for re-peeling.
• Contract boring: short runs bored without a second set-up.

• Isolate the spindle before changing the cutter head.
• Clamp the block before the feed is engaged.
• Keep the stroke path clear during boring.
• Wear eye protection when clearing foam from the bore.

• Check the cutter head edge at every shift start.
• Clean foam dust from the guides daily.
• Grease the feed screw weekly.
• Check spindle run-out monthly and record it.

The machine travels in an export-grade wooden case with the electrics protected and the cutter or blade assembly braced separately. Machine weight is 800 kg and the overall dimension is 6000*1500*1800 mm, so the unit is quoted against a 20ft or 40ft container depending on the line it ships with.

A packing list, wiring diagram, operation manual and CE declaration travel with every unit. Delivery is 45 working days after downpayment; installation and commissioning support is available remotely or on site.
