CNC machining, forging, GD&T, heat treatment, surface finish, NDT — every discipline in one page.

CNC Turning & Milling

Multi-axis CNC machining centres and turning centres with live tooling. Tolerances to IT4 grade (±0.005 mm on diameter for Ø10-18 mm). Dedicated titanium, Inconel, and stainless machining cells with coolant-through tooling and Ti-specific carbide inserts.

Simultaneous 5-Axis Machining

Full simultaneous 5-axis (XYZBC or XYZAC) eliminates re-fixturing, enables undercut machining, and allows optimal cutter engagement for complex aerospace turbine blades, impellers, and structural brackets. Dimensional accuracy ±0.010 mm on 5-axis features.

Closed-Die & Open-Die Forging

Hot forging (900–1200°C for steel; 900–955°C for Ti-6Al-4V) refines grain structure, closes porosity, and achieves mechanical properties 30% superior to equivalent castings. Closed-die forging achieves near-net-shape with flash; open-die for large sections. Die design includes draft angles, corner radii, and flash gutters.

Geometric Dimensioning & Tolerancing

All drawings follow ASME Y14.5-2018. Critical tolerance stack-up is analysed using 1D worst-case and RSS Monte Carlo simulation (10,000 trials). GD&T ensures functional interchangeability regardless of which allowable form a feature takes — purely dimensional tolerances cannot achieve this.

GD&T StandardASME Y14.5-2018

Position tolerance⊕ Ø0.05 A B C (typical)

Flatness▭ 0.02 (sealing faces)

Cylindricity⌭ 0.005 (bearing bores)

Runout↟ 0.010 TIR (rotating parts)

TOLERANCE STACK-UP EXAMPLE

4 parts in assembly, each ±0.05mm:
Worst Case: ΔT = 4×0.05 = ±0.20 mm
RSS: ΔT = √(4×0.05²) = ±0.10 mm
GD&T reduces this further by specifying
true position (cylindrical tolerance zone)
instead of ±X, ±Y (square zone 57% larger)
→ Fewer rejections, better fit

Surface Finish Engineering

Surface texture directly affects fatigue life, sealing, tribology, and corrosion resistance. Ra, Rz, Rq, and Rmax measured by contact profilometry (Mitutoyo SJ-410) and white light interferometry. Post-processing: vibratory finishing, lapping, honing, electrolytic polishing, shot peening.

Turning (coarse)Ra 6.3 µm (N9)

Turning (finish)Ra 0.8 µm (N6)

GrindingRa 0.2 µm (N4)

HoningRa 0.025–0.1 µm (N2-N3)

LappingRa 0.012 µm (N1)

ElectropolishRa <0.1 µm + passive

SURFACE FINISH vs FATIGUE LIFE

Ground surface (Ra 0.2): Kf = 1.0 → full strength
Fine turned (Ra 0.8): Kf ≈ 0.96 → -4% fatigue
Coarse turned (Ra 3.2): Kf ≈ 0.88 → -12% fatigue
Rough (Ra 12.5): Kf ≈ 0.70 → -30% fatigue

Shot peening: σ_res = -500 MPa compressive
→ Doubles fatigue life for Ti-6Al-4V

CMM Inspection

Coordinate Measuring Machine (CMM) inspection for 100% dimensional verification of critical features. Renishaw REVO 5-axis scanning head achieves 0.001 mm volumetric accuracy. Results output as BALTECH/PC-DMIS reports with geometric deviation maps and histogram analysis.

Non-Destructive Testing (NDT)

100% inspection with NDT methods appropriate to material and defect type. Eddy current for surface cracks in conductive parts; ultrasonic testing (UT) for subsurface voids/inclusions; dye penetrant (PT) for surface-open defects in non-porous materials; radiography (RT) for castings and welds.

🌊 Ultrasonic Testing (UT)

Pulse-echo UT at 5–15 MHz detects subsurface defects ≥0.5 mm equivalent diameter. Used for titanium and Inconel forgings. ASME Section V / EN 10308. Phased array UT (PAUT) for complex geometries.

⚡ Eddy Current (ET)

Electromagnetic induction detects surface and near-surface cracks in conductive metals. Sensitivity: cracks >0.1mm depth. High-speed scanning: 100+ parts/hr. No couplant needed. Used for bore inspection.
