Automatic Feeding Foam Boring Machine with 4 kW Motor and 2300 mm Boring Length

The C519 is a 4 kW CNC foam boring machine with automatic feeding. Boring length is 2300 mm, hole diameter range is 50-80 mm, machine weight is 1500 kg and the overall dimension is 6000*1600*2500 mm. The machine is CE certified.

Boring is a support step, not the product. Every minute the operator spends holding and pushing a block is a minute not spent on peeling or cutting. Automatic feeding turns the C519 into a station the operator loads and leaves, which is where the throughput gain comes from.

• Model: C519
• Boring length: 2300 mm
• Hole diameter: 50-80 mm
• Motor power: 4 kW
• Weight: 1500 kg
• Footprint: 6000*1600 mm

1. Set the recipe. Enter the bore size, feed rate and stroke for the batch on the CNC control.
2. Load the block. Place the block against the end stop and close the clamp.
3. Start the cycle. The feed advances the block into the rotating cutter at the set rate.
4. Unload and reload. The operator prepares the next block while the current one is bored.
5. Check the first block. Measure the bore and confirm the setting before the batch continues.
6. Log the batch. Record bore size, block count and any deviation for the shift.

Set the recipe once and run the batch. Re-entering settings block by block is where variation creeps into a run, and the CNC control is there to remove that variation.

Boring looks like a fast operation and is often treated as one, but the real cost is the operator's attention. If the operator has to stand at the machine and push the block through the cut, the boring station sets the pace for the whole line. Automatic feeding breaks that link: the machine advances the block while the operator loads the next one.

The 4 kW spindle is part of the same argument. A spindle that bogs down at depth forces a slower feed, and a slower feed lengthens the cycle. Holding torque through the full 2300 mm lets the feed run at the rate the foam allows, not the rate the motor can survive.

The CNC control is what makes the gain repeatable. Once the recipe is set, every block in the batch is bored with the same feed, stroke and centre position, so the bore quality does not drift from block to block or from shift to shift.

• Operator time: loading and unloading, not holding and pushing.
• Cycle time: full torque allows a feed rate set by the foam, not the motor.
• Repeatability: CNC recipes keep the bore consistent across the batch.

• One operator, one station: the operator loads the block and starts the cycle.
• Automatic feed: consistent advance rate produces a consistent bore wall.
• 4 kW spindle: steady torque at full depth in denser PU foam.
• CNC settings: feed, stroke and centre position are repeatable between batches.
• 2300 mm stroke: full-length blocks bored in one pass.
• 1500 kg frame: mass under the spindle reduces vibration at depth.
• CE certified: export-ready guarding and electrics.

• PU sponge factories: continuous boring ahead of the peeling line.
• Mattress foam plants: blocks bored for shaft handling at line speed.
• Cylinder foam production: centre holes bored in rolls before peeling.
• Foam conversion workshops: boring handled by one operator alongside other work.
• Recycling lines: reclaimed blocks prepared for further processing.
• Contract boring: repeatable settings across mixed batches.

Most boring faults show up as a hole that is off centre or oversized before they show up as a mechanical breakdown. Check clamping, cutter condition and feed speed first, because those three settings cause most of the scrap on a boring station.

Automatic feed does not remove the need to check the clamp. A block that is not clamped square will still feed, and the bore will still be off centre; the machine cannot correct a bad set-up.

Keep the feed zone clear before starting the cycle. Automatic feed advances whatever is in front of it, including tools left on the table.

• Confirm the recipe matches the batch before the first block.
• Check the clamp and end stop with every block.
• Keep the feed table clear of tools and offcuts.
• Stop the spindle before reaching into the boring zone.
• Measure the first block and log the result.

The feed system is the part that carries the throughput advantage, so it needs the most consistent attention. Check the feed screw, slideways and clamp pressure on a weekly schedule and keep foam dust off the guides.

The spindle and cutter head follow the same rule as any boring machine: a sharp head and correct belt tension protect the bearing, and a dull head shortens the life of both.

• Inspect the cutter head daily and replace on condition.
• Clean the feed screw and slideways at shift end.
• Check clamp pressure and end stop weekly.
• Check belt tension and spindle bearing play monthly.
• Grease the feed screw and guides on schedule.

The machine ships in a reinforced export crate with the spindle head, feed table and control panel braced for transport. The crate matches the 6000*1600*2500 mm machine envelope.

The shipment includes the crating list, lifting points and a commissioning checklist, with remote support available during installation.
