Product catalog summary

Specifications:
The document outlines specifications for collet chuck types with coolant supply, specifically the BT40-HDC16A-135CS and BT40-CDC16-135 models. These models are designed for high-speed operations up to 8,000 RPM and can handle coolant pressures up to 870 psi. The document also mentions different types of cutters, such as the FDC-OH type with oil holes and the FDC-C type without oil holes, both designed for effective coolant flow.

Design Features:
The collet chucks are completely sealed to prevent damage to ball bearings from coolant leakage. They feature a replaceable seal unit for easy maintenance, ensuring quick and low-cost upkeep. The NT fluid heads are designed to deliver coolant directly to the tool tip, enhancing cutting performance by flushing out chips and reducing heat.

Performance and Maintenance:
The document emphasizes the importance of multi-seal construction and corrosion-resistant surface treatment for precise and trouble-free operation. It also highlights the benefits of delivering coolant directly to the tool tip, which extends tool life and prevents breakage.

Technical Details:
Various dimensions and part numbers are provided for different components, including the seal sleeve, seal unit, and plunger types. The document specifies maximum RPMs for different configurations and provides ordering examples for different models.

Maintenance Recommendations:
When replacing seal units, both the seal body and seal sleeve should be purchased together. For replacing seals only, a seal set consisting of two seals and one seal sleeve is recommended. The document notes that CT S-CS coolant inducers must be returned to NT USA for seal unit replacement.

Additional Information:
Accessories such as coolant collets and spanner wrenches are sold separately, and specific pages are referenced for further details on these items.
