CNC Machined Blocks FAQ
What block types can you manufacture?
We manufacture custom CNC machined blocks including mounting blocks (equipment fastening and assembly), bearing blocks (rotating component support), valve blocks (fluid control and manifold integration), manifold blocks (hydraulic and pneumatic integration), spacer blocks (precise spacing and alignment), alignment blocks (precision reference blocks for assembly), tooling blocks (jigs and fixtures), and custom profile blocks. All blocks are CNC machined to your exact specifications.
What materials are best for heavy-duty blocks?
Steel 4140 is the standard choice for heavy-duty blocks — tensile strength 655 MPa, excellent machinability, and superior rigidity for machinery and industrial applications. Stainless steel 316 offers corrosion resistance with good strength for chemical and marine environments. For aerospace applications, consider 17-4 PH stainless (1310 MPa) or titanium. Aluminium 7075-T6 is ideal for weight-critical applications requiring high strength-to-weight ratio.
What tolerances can you hold on block dimensions?
Standard CNC machining on blocks achieves ±0.05mm on all dimensions. Precision machining with CMM verification can hold ±0.01mm. For critical bearing surfaces or seal surfaces, we recommend finishing operations to achieve ±0.005mm or better. Flatness and straightness are typically within ±0.05mm per 100mm for standard machining.
What is the typical lead time for custom blocks?
Quote turnaround is 2 business days. Once order is confirmed, lead times depend on block complexity and current shop load. Simple mounting blocks typically deliver in 3–5 business days. Complex manifold blocks with internal passages may require 5–10 business days. Rush lead times are available — contact our engineering team for expedited scheduling.
Can you manufacture blocks with internal passages?
Yes. We regularly machine complex manifold blocks with internal galleries, passages, and cross-drilling for hydraulic and pneumatic integration. Multi-axis CNC drilling and milling allows us to create sophisticated port patterns and internal channels in a single setup. All passages are drilled, bored, and threaded to your specifications with full dimensional and cleanliness verification.
Do you offer surface treatments for corrosion resistance?
Yes. Surface treatments are managed as part of our supply service. We arrange anodising (for aluminium blocks), hard chrome plating, electroless nickel plating, and stainless steel material selection. Specify your treatment requirement on your drawing or in your quote request, and we will include it in the quote.
