2300 mm Boring Length Foam Boring Machine with 45-80 mm Diameter and 230 r/min Speed

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

A cylinder block needs a centre hole before it can be fixed on the peeling mandrel. Bore it in two set-ups and the second bore rarely meets the first on the same centre line, so the block wobbles on the mandrel and the peeled sheet runs thick and thin around the circumference.

The TDP-52 is built around a 2300 mm stroke, which covers a full block in one pass. That single feature is what keeps the bore straight, and it is the reason the machine sits between the foaming line and the peeler in a cylinder foam plant.

• Model: TDP-52
• Boring length: 2300 mm
• Hole diameter: 45-80 mm
• Spindle speed: 230 r/min
• Motor power: 1.5 kW
• Weight: 800 kg

1. Set the centre height. Match the spindle to the block diameter so the bore runs through the middle.
2. Clamp the block. Square the block to the spindle and lock the end stop.
3. Fit the cutter head. Select the head for the required 45-80 mm hole.
4. Start the feed. Let the feed carry the block into the rotating cutter.
5. Bore to 2300 mm. The stroke covers the full block without an intermediate stop.
6. Withdraw and check. Retract the cutter and check the bore at both ends.

Bore a scrap block first when the cutter head is new. Five minutes on scrap is cheaper than a peeled block that has to be re-bored.

A cylinder block is peeled from the mandrel outward. If the bore is stepped, the block does not sit square on the mandrel, and every sheet peeled from it carries the same error. The operator then spends the shift trimming sheets instead of stacking them.

The 2300 mm stroke removes the re-chuck. One continuous cut means one centre line, and the block loads onto the peeler in the position it was bored.

The 1.5 kW spindle is enough for foam. The load on the cutter is modest, so the requirement is steady speed rather than torque, and a small drive keeps the station cheap to run.

• Accuracy: one continuous bore instead of two set-ups.
• Line flow: the block goes from bore to mandrel without re-alignment.
• Cost: 1.5 kW station power keeps the step inexpensive to run.

• 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.
