Our Happy Clients
What are your core CNC machining capabilities?
We specialize in precision CNC machining, including 3, 4, and 5-axis milling, CNC turning, and mill-turn operations. Our focus is on high-accuracy aluminum components, providing scalable solutions from rapid prototyping to high-volume mass production.
Do you provide secondary surface finishing for machined parts?
Yes, we offer a comprehensive range of surface finishes. For aluminum parts, this includes Type II and Type III (Hardcoat) anodizing, bead blasting, polishing, brushing, and powder coating to meet both your functional and aesthetic requirements.
Which aluminum alloys do you most commonly machine?
We extensively work with aerospace and industrial-grade aluminum alloys, most notably 6061-T6, 7075-T6, 5052, and 2024. These materials offer an excellent balance of machinability, strength-to-weight ratio, and corrosion resistance.
What is the tightest machining tolerance RALLY can achieve?
Depending on the material and part geometry, our advanced 5-axis CNC machines and skilled technicians can hold standard tolerances of ±0.01 mm, and up to ±0.005 mm for highly critical dimensions.
What is your standard turnaround time for prototypes vs. mass production?
Rapid prototypes typically ship within 1 to 5 business days. For low-volume production (100-1,000 parts), lead times average 5 to 15 days. High-volume mass production runs are scheduled based on batch sizes, usually taking 2 to 4 weeks.
How quickly can I get a quote for my project?
Our engineering team reviews your files and typically provides a detailed, comprehensive quote within 12 to 24 hours. Complex multi-part assemblies may require slightly more time for accurate manufacturing evaluation.
What CAD file formats do you accept for quoting?
We accept all major 3D and 2D CAD formats. For 3D models, STEP (.stp/.step) and IGES (.igs/.iges) are preferred. For 2D drawings (which are essential for checking tolerances and threads), PDF or DWG formats are ideal.
How do you ensure the dimensional accuracy of my parts before shipping?
We employ a rigorous quality control process, utilizing advanced metrology equipment such as ZEISS Coordinate Measuring Machines (CMM), optical vision systems, and profilometers. We can provide full inspection reports and material certifications upon request.
