How to control cutting heat during CNC machining of plastics?
A: Employ a three-stage temperature control strategy: Tool optimization — diamond-coated tools with sharp cutting edges (rake angle >10°); Cooling adaptation — low-temperature air cooling for PEEK, minimal lubrication for ABS, alcohol cooling for PC; Parameter control — high spindle speed (8000-15000 rpm) with shallow depth of cut (≤0.1mm).
What are the anti-deformation measures for thin-wall plastic parts?
A: Implement a four-step anti-deformation process: Structural design — add stiffening ribs (40-60% of wall thickness); Machining strategy — symmetrical alternating cutting with layered machining (each layer 0.05mm); Special fixturing — low-melting-point alloy support filling; Stabilization — constant-temperature aging at 65-80°C for 2-4 hours.
How to reduce tool wear when machining glass-fiber/carbon-fiber reinforced plastics?
A: Professional process combination: Tooling — PCD tools (tool life increased 5-8 times); Parameters — climb milling with high feed rate (≥0.15mm/tooth); Dust extraction — 0.15MPa high-pressure vacuum suction; Speed — recommended 180 m/min for glass-fiber reinforced nylon.
How to achieve optical-grade surfaces on transparent plastics?
A: Three-stage polishing process: Mechanical polishing — diamond polishing paste (grade W3); Chemical polishing — ethanol + ethylene glycol mixture; Flame polishing — oxy-hydrogen flame (280-320°C); plus a clean environment: Class 1000 cleanroom.
How to ensure accuracy in CNC machining plastic parts with metal inserts?
A: Co-machining solution for dissimilar materials: Machining sequence — metal first, then plastic; Temperature control — interface temperature difference <3°C; Tooling — progressive cutting with variable-diameter tools; Compensation — laser scanning plus thermal expansion coefficient difference compensation.
