5 Products · MCS-001 to 005
Multi-face mounting seats, complex angular brackets, irregular connecting blocks, multi-face locating blocks, and integrated mounting bases. These parts carry multiple functional surfaces at defined angles with tight parallelism, perpendicularity, and position tolerances — the defining challenge is maintaining all geometric relationships across multiple setups or in a single 5-axis operation.

Manufacturing Capability
Why Complex Structures Need Dedicated Capability
CAP / 01
5-Axis Simultaneous CNC — All Faces in One Setup
The defining advantage for multi-face structural parts: machining all geometric features in a single 5-axis setup eliminates re-fixture positioning error. For a mounting base with six functional faces, each re-fixture introduces ±0.01–0.05 mm error. One 5-axis setup holds all geometric relationships from a single datum — achieving the ±0.005–0.01 mm inter-face positioning that complex structural parts require.

High-Flatness Precision Grinding
Surface grinding for base plates and datum faces to ±0.003 mm flatness. Stress-relief anneal before grinding for aluminium and steel plates prevents post-grind distortion. Flatness verified on CMM after grinding.

Large Format Machining — Up to 2,000 mm
Large precision mounting plates and skeleton frames up to 2,000 mm length, 1,200 mm width on horizontal machining centers with thermal compensation. Large parts particularly benefit from stress-relief annealing of plate stock before finish machining — plates cut from rolled stock contain residual stress that causes distortion after material removal. We anneal all aluminium plate stock above 300 mm dimension before precision machining.

DFM Review & Fixturing Plan
Drawing reviewed for machining accessibility, datum strategy, and fixturing plan. 5-axis single-setup vs multi-setup analysis. Feedback within 24h.
02
Material Stress Relief
Aluminium plate and billet stress-relieved at 200–250°C before roughing cut. Prevents post-machining distortion on precision plates and thin-wall structures.
03
Rough Machining (Leave 0.3mm Stock)
All faces rough cut with 0.3 mm finish stock. Part allowed to temperature-equalise and any residual stress released before semi-finish and finish operations.
04
5-Axis Finish Machining
All functional faces finish machined from single datum — 5-axis simultaneous where required. Tight parallelism, perpendicularity, and position maintained relative to a single part datum.
05
Surface Grinding (where spec'd)
Datum faces ground to flatness ±0.003–0.005 mm after machining. Used for base plates, datum blocks, and parts where milled flatness is insufficient.
