Precision Equipment Base Plates serve as the rigid structural foundation for alignment-critical industrial systems, automation assemblies, and heavy machinery. Built to exact OEM print specifications, these plates maintain long-term dimensional stability under dynamic mechanical loads.
Primary Function: Provides a flat, parallel reference plane for mounting actuators, gearboxes, rails, and optical assemblies.
Manufacturing Route: Saw cutting → Rough milling → Thermal stress relief (optional) → Precision CNC milling → Surface grinding → Threading/tapping → Deburring → Surface treatment → Inspection.
Standard Compliance: ISO 2768-mK (tolerances), ASTM/DIN material standards.
Key Features
Structural Rigidity: Optimized ribbing and thickness distribution prevent deflection and torsional twisting under heavy payloads.
Precision Machining Zones: Critical datum surfaces and mounting pads are finished in a single clamping setup to guarantee perpendicularity and parallelism.
Thread Integrity: Tapped holes (UNC, UNF, Metric) are precision-machined with controlled depth and thread engagement, verified by Go/No-Go thread gauges.
Stress Relieved: Plates undergo thermal annealing or natural aging prior to finish machining to eliminate internal residual stresses and prevent post-machining warpage.

Frequently Asked Questions
Q: What is the standard Minimum Order Quantity (MOQ)?
A: MOQ is 1 piece for prototypes and custom engineered orders. Batch pricing tiers apply for volume production.
Q: What is the typical lead time?
A: Prototypes typically ship in 10 to 15 business days. Batch production schedules are established upon order confirmation (averaging 3 to 5 weeks).
Q: What 2D drawing formats are required for quotation and production?
A: PDF drawings containing critical tolerances, surface finish callouts (Ra), geometric dimensioning and tolerancing (GD&T), and material specifications, accompanied by a 3D STEP or IGES file.
Q: How do you prevent plate warpage after deep pocket milling?
A: We utilize stress-relieved stock material, balanced roughing/finishing toolpaths, and intermediate thermal stabilization steps to neutralize internal material stresses.
Q: Can you handle post-machining surface treatments?
A: Yes. We manage commercial treatments including clear/black anodizing, hard anodizing, electroless nickel plating, black oxide, and powder coating.
Q: Are material test reports (MTRs) provided?
A: Yes. Mill test certificates (EN 10204 3.1) are supplied for all raw metals upon request prior to production.
