Robotics CNC machining parts are precision-machined aluminum, stainless steel, or titanium components used in robot arms, joints, end effectors, and frames. CNC machining achieves tolerances of ±0.01mm to ±0.05mm, which is required for servo motor mounts, bearing housings, and harmonic drive interfaces. At GD Prototyping, we produce robotics parts in 7 to 15 days with full ... Read more

Introduction CNC Machining has revolutionized construction with aluminum. In 2026, the new standard is outlandish engineering designs which challenge 3-axis machining. Gone are the days with lead times of weeks, and several setups for intricate multi-faceted features, and deep cavity machining. At GD Prototyping, engineering support partnered with 4-axis and 5-axis Aluminum CNC Machining enables ... Read more

Vacuum Casting Prototyping has long been valued for speed and low-volume cost, but many buyers still assume it delivers parts that look like prototypes—soft edges, visible bubbles, or mismatched colors. That assumption is outdated. In 2026, GD Prototyping has transformed vacuum casting into a surface-critical manufacturing process. Today, your small batch of 20 or 200 ... Read more

A European industrial automation OEM needed 304 hydraulic valve bodies in Aluminum 6061-T6, with tolerance held to ±0.02mm and surface finish at Ra 0.8 μm. Using 5-axis CNC machining on a DMG Mori DMU 65 monoBLOCK, our team at GD Prototyping delivered all 304 parts in 12 days. First-pass yield hit 99.3%. The client cut ... Read more

We machined 200 aluminum 6061-T6 heat-dissipating electronic housings for a South Korean consumer electronics OEM. Parts measured 120mm x 85mm x 22mm, with tolerances held to ±0.01mm on critical bore fits. Using 5-axis CNC milling on a DMG Mori DMU 50, we delivered all 200 parts in 9 working days with a 99.5% first-pass inspection ... Read more

TL;DR We machined 120 titanium Grade 5 (Ti-6Al-4V) surgical implant housings for a European medical device client. Parts required ±0.01mm tolerances, Ra 0.4 µm surface finish, and a 14-day lead time. We solved a thin-wall deformation issue on the second attempt and delivered a 99.2% first-article pass rate — on time. Introduction A European orthopedic ... Read more

CNC machining is the most reliable method for producing tight-tolerance titanium aerospace parts. Titanium alloys like Ti-6Al-4V (Grade 5) can be machined to tolerances of ±0.01mm using 5-axis CNC milling with proper tooling and coolant strategies. This guide covers material grades, machining parameters, design rules, cost factors, and how to choose the right supplier. Why ... Read more

We used full simultaneous 5-axis CNC machining on a European aerospace OEM's titanium turbine support bracket. The part was Ti-6Al-4V, 187mm x 94mm x 62mm, with a ±0.01mm critical bore tolerance. We delivered 50 validated parts in 14 days, achieving a 98% first-pass inspection rate and zero field failures in post-delivery functional testing. Introduction An ... Read more

A European automotive supplier needed 150 aluminum sensor housings with wall thicknesses of 1.2mm and bore tolerances of ±0.01mm. We machined them from Aluminum 6061-T6 using 5-axis CNC milling on a DMG Mori DMU 65 monoBLOCK. Final inspection showed a 99.3% first-pass yield. Parts shipped in 12 working days, 2 days ahead of schedule. Introduction ... Read more

CNC machining is the most reliable method for producing plastic functional prototypes with tight tolerances (±0.01 mm to ±0.05 mm), real engineering-grade material properties, and fast turnaround (3 to 7 days). It works best for 1 to 100 units where design validation, fit testing, or functional performance testing is required before committing to production tooling. ... Read more

We machined 75 units of a precision aluminum 6061-T6 sensor housing for a European automotive client using 5-axis CNC milling on a DMG Mori DMU 50. Parts measured 148mm x 62mm x 38mm with a tolerance of ±0.02mm. We delivered all 75 units in 12 business days with a 98.7% first-pass yield. This case study ... Read more
