Product details

PP Boards – an excellent insulation material widely used in various industries. For precision fabrication, CNC machining is ideal for creating high-quality insulation material CNC machined parts. Whether you need custom shapes or complex designs, insulation material processing via insulation material CNC processing ensures durability and accuracy. PP Boards’ versatility makes them perfect for both industrial and commercial applications.

Points to Note in CNC Machining of PP Boards

Know Material

Low melting point: PP starts melting around 160–170°C, so it can get gummy and stick to tools. Keep things cool to avoid gooey messes or warping.

Expands when hot: PP grows as it heats up. Let parts cool completely before measuring or finishing—otherwise, sizes will be off.

Tough but clingy: Chips love to wrap around tools. Clear them often to keep your cuts clean.

Picking the Right Tools

Sharp is key: Use high-speed steel (HSS) or carbide tools—they stay sharper longer and reduce heat.

Coolant helps: For long jobs, tools with coolant channels keep temperatures in check.

Dialing In Your Settings

Speed: Go slow to medium (e.g., 300–600 RPM for milling).

Feed rate: Stay in the middle (e.g., 0.1–0.3 mm/tooth).

Cut depth: Light passes work best (0.5–2 mm for roughing; 0.1–0.5 mm for finishing).

Holding It Down Right

Gentle grip: Use soft jaws to avoid squishing or marking the material.

Vacuum tables: Great for thin or big sheets—they cut down on vibrations.

Keeping Things Cool

Blow it away: Compressed air cools and blows chips clear. Skip oil coolants—they can mess up PP.

Dry is fine: If possible, skip coolant altogether to avoid moisture warping.

Dealing with Chips

Clean often: PP chips are clingy. Clear them regularly to avoid clogs or re-cutting.

Suck it up: Use a dust extractor to keep your workspace tidy.

Getting a Smooth Finish

Sharp tools only: Dull tools tear up PP. Check and replace them often.

Take it layer by layer: For thick sheets, multiple passes prevent warping from stress.

Safety First

Gear up: Wear goggles and a mask—PP dust isn’t fun to breathe.

Fire risk: PP burns easily. Keep sparks and high heat away.

Final Touches

Deburring: Hand-sand or scrape edges. Heat-based methods can warp the part.

Let it relax: For critical parts, wait 24 hours before measuring/assembling—PP needs time to settle.
