Compressor Housing Machining — Bores, Tools, RFQ
The housing RFQ still asked for “compressor tools” while the print marked bearing bores, locating diameters, and oil galleries that do not share one flute story—and the scroll-plate page does not own this case.
This page owns compressor housing bore machining: housing hole map, short Al vs ferrous fork, tool match, and RFQ. Scroll-plate / orbiting-disk work stays on Aluminum Scroll Compressor Plate Machining. Industry context: Automotive Powertrain. XRZ quotes from your housing print with critical bores marked (sample validation · Custom Cutting Tool RFQ).
Housing bore map
| Feature | What usually drives tooling |
|---|---|
| Bearing / main fit bores | Diameter, roundness, alignment → often drill → measure → PCD ream |
| Locating / register diameters | Position + fit; ream when gauge requires |
| Oil / coolant / vent holes | Create-hole + chip/burr plan; ream only when print demands |
| Coaxial / multi-diameter stacks | Treat as one alignment problem — soft EV Housing Coaxial Bore Machining (sibling) |
Do not expand into a scroll-plate encyclopedia—soft Aluminum Scroll Compressor Plate Machining.
Aluminum vs ferrous (short fork)
| Material fork | Typical holemaking posture |
|---|---|
| Aluminum / Al-Si housings | Carbide create-hole + PCD ream on fit-critical bores; send Si% when known |
| Ferrous / cast-iron cases | Carbide drill primary; ream only where print + gauge justify—do not default every bore to PCD |
Soft material depth (do not restate): Aluminum silicon content — PCD vs carbide · PCD reamer vs carbide reamer. High-Si housing application: High-Silicon Aluminum Hole Machining (sibling).
Tool cards (short — not full catalog)
| Need | Open |
|---|---|
| Fit-bore finish | Custom PCD Reamer |
| Create-hole | Solid Carbide Drill |
| Cycle collapse when print justifies | Combination Drill-Reamer |
Combination tools earn a station when cycle time and capability justify collapsing steps—not as a default housing slogan. Soft: Drill-then-ream vs PCD combination.

Milling appears only as support when a face lands on the same print—never as a second pillar on this URL.
Housing RFQ pack
| Must send | Why |
|---|---|
| Housing print/model + revision; critical bores marked | Separates finish bores from clearance |
| Hole chart: Ø, depth, tol, alignment/coaxial callouts if on print | Freezes drill vs ream scope |
| Material / alloy + Si% when Al | Wear and edge discussion—not a life promise |
| Pre-hole method + allowance for finish bores | Incoming band before geometry freeze |
| Machine, holder, stickout, measured runout, coolant | Trial realism |
| Volume band + sample yes/no + written acceptance | First-article before production talk |
Checklist: PCD Reamer RFQ Checklist.
How is compressor housing machining different from scroll plate machining?
Aluminum Scroll Compressor Plate Machining owns scroll / plate features. This page owns the housing case bore map—bearing, locating, oil/coolant—and the RFQ for those holes. Use the scroll page for plate work; send housing prints here.
Do all compressor housing bores need PCD reaming?
No. PCD reaming belongs on fit-critical bearing and precision bores after a controlled pre-hole. Clearance and non-gauge openings often stay on the carbide create-hole path. Mark critical bores and send material notes via Custom Cutting Tool RFQ · product Custom PCD Reamer.
When is a combination drill-reamer useful on a housing?
When cycle time and process capability justify collapsing create-hole and finish on a diameter the print allows—not as a default for every housing bore. Soft: Drill-then-ream vs PCD combination · Combination Drill-Reamer.
What should I send for a compressor housing RFQ?
Housing print with critical bores marked, hole chart, material/Si% when Al, pre-hole/allowance for finish bores, holder/runout/coolant, and sample acceptance list. Upload via Custom Cutting Tool RFQ.
