5. Accessories and Spare Parts

Wrenches, adjusting screws, sealing nuts, coolant-through components, protective cases, taper cleaners, and exclusive stop blocks for angle heads and air turbine spindles.
Collets and nuts must often be ordered separately; use only BIG-manufactured collets and nuts with BIG chuck bodies to maintain accuracy.

6. Usage Recommendations and Limitations

Adhere strictly to maximum rotational speeds and coolant pressure limits (generally max 2 MPa) to ensure safety and tool longevity.
Use exclusive stop blocks for angle heads and air turbine spindles to prevent damage and ensure correct positioning.
Coolant-through features are recommended for high-speed and heavy-duty machining to improve cooling and chip evacuation.
Do not use neat oil coolant with air turbine spindles due to fire risk.
Proper assembly using specified wrenches and adjusting screws is critical to maintain precision and avoid damage.
BIG-PLUS tooling is compatible with machining centers equipped with conventional spindles.

7. Standards and Compliance

All components conform to DIN 69871 A/B (BIG-PLUS) standards ensuring interchangeability, reliability, and enhanced rigidity via dual contact spindle systems.
Tapping holders comply with DIN and ISO standards for thread sizes and tapping ranges.
