Why do our Customers Choose Tufnol for CNC Machining Projects?

Tufnol, a phenolic resin laminate composite, excels in precision machining for applications requiring electrical insulation, mechanical strength, and chemical resistance. Its machinability, when paired with advanced CNC techniques, makes it ideal for electrical (e.g., insulators and switchgear), mechanical (e.g., gears and bearings), and aerospace (e.g., lightweight panels).

Key benefits include:

  • Excellent Electrical Insulation: High dielectric strength (up to 10 kV/mm), perfect for machined insulators.
  • High Mechanical Strength: Compressive strength around 300 MPa, suitable for load-bearing machined parts.
  • Chemical and Thermal Resistance: Withstands temperatures up to 120°C and resists acids/oils.
  • Low Weight and Dimensional Stability: Density ~1.3 g/cm³, ideal for precision machined components.
  • Sustainability: Durable and long-lasting, reducing replacement needs in 2025 eco-focused designs.

Midlands-based Tufnol CNC Machining Specialists

Precision CNC Machining for Tufnol Components

As Tufnol machining specialists in Coventry, we focus on high-accuracy CNC operations to produce intricate components, from prototypes to full production runs. Our 3, 4, and 5-axis CNC mills (up to 2m x 2m envelope) and CNC lathes (500mm diameter) achieve tolerances as tight as ±0.01mm, handling Tufnol’s composite nature with dust extraction and sharp tools. With crane handling up to 10 tonnes, we manage large-scale machined workpieces with precision.

We work with industry-standard Tufnol grades, including:

  • Crow (Paper-Based) – Economical with good insulation for electrical CNC machining
  • Whale (Cotton-Based) – High mechanical strength for gears and bearings
  • Bear (Fine-Weave Cotton) – Superior toughness for demanding machined parts
  • Kite (Glass-Based) – High temperature resistance for aerospace
  • Custom-Specified Grades – Sourced to meet your exact machining requirements

We accept client-supplied materials or source from approved UK suppliers.

Repeatable Precision with Robotic Assistance

For batch production of machined components, our robotic systems ensure consistent results, ideal for repeatable features like slots or holes in Tufnol parts. Overseen by certified engineers, this boosts efficiency for Tufnol CNC machining specialist projects.

Assembly & Integration of Machined Components

We can integrate machined components into complex assemblies or sub-assemblies, incorporating precise mounting points for hydraulic systems, electronics, or drivetrains—essential for automotive and industrial applications.

Testing & Surface Finishing Services

We conduct pressure and leak testing to verify machined enclosures. Additionally, we can also offer surface finishing to enhance performance:

  • Polishing: For smooth, low-friction surfaces
  • Coating: For added chemical resistance
  • Blasting: For textured industrial parts

Accredited Quality Systems

Our ISO 9001:2015 certification ensures traceability. We provide procedures, First Article Inspection Reports (FAIRs), and dimensional reports. Inspections use calibrated Coordinate Measuring Machines (CMMs) for machined precision.
