Pump Housing Machining: Tooling and Parameters
October 7, 2026 · Exactalloy Technical Team
Pump Housing Machining has its own material mix, tolerance culture and cycle-time pressure. Tooling has to match all three.
Quick answer: Start from the material group, then choose the coating for temperature and adhesion, the geometry for reach and rigidity, and the coolant strategy for chip evacuation.
Material and process challenges
Heat, work-hardening, abrasiveness and thin-wall distortion are the recurring problems in this segment.
Recommended tooling
Select from the relevant family — end mills for profiling, drills for holes, thread mills for threads, and indexable tooling where batch size justifies it.
Parameters that matter
Control surface speed first, keep feed per tooth high enough to cut rather than rub, and use the largest axial depth the set-up supports.
Quality and inspection
Define the acceptance criteria before the first cut — surface roughness, dimensional tolerance and burr limits.
Specifications at a glance
| Concern | Tooling response |
|---|---|
| Heat at the edge | AlCrN or AlTiN coating, high-pressure coolant |
| Work hardening | Sharp positive geometry, no dwell |
| Abrasiveness | Ultra-fine grain substrate, wear-resistant coating |
| Distortion | Light finishing passes, stress-relieved stock |
| Cycle time | High-feed or trochoidal strategies |
