Features of Precision Machined Base Plates
When machining large precision base plates, deformation and dimensional stability are common challenges. We address these through proper clamping methods, aging treatment, and step-by-step processing to ensure accuracy and stability. Below are the main features of our base plates:
High Flatness We can control the flatness of base plates within 0.02 mm. For large or thin plates that tend to warp during machining, we use multiple roughing and finishing steps combined with aging treatment to minimize deformation and maintain flatness after installation.
Accurate Hole Positioning We use 4-axis and 5-axis CNC machines to process threaded holes, dowel pin holes, and hole arrays. For base plates with large hole spans, we perform multiple position corrections and measurements to reduce cumulative error and support accurate alignment during assembly.
Tight Tolerances We can routinely achieve ±0.005 mm tolerances. For critical mating features, we apply step-by-step machining with intermediate resting periods to reduce the effects of temperature and internal stress.
Surface Finish Surface roughness is generally controlled between Ra 0.8 – 3.2 μm. We can provide standard industrial surfaces or smoother finishes according to customer requirements. Tool paths and cutting parameters are optimized to avoid visible tool marks.
Structural Strength We select common materials such as aluminum alloys, carbon steel, and stainless steel. By following a reasonable machining sequence and avoiding excessive material removal, we maintain sufficient rigidity to meet the strength requirements of equipment and automation applications.
Corrosion Resistance Stainless steel base plates are passivated after machining. Aluminum alloy plates can be anodized or hard anodized. We select appropriate surface treatments based on the customer’s operating environment to enhance corrosion resistance.
FAQS
What is a CNC machined base plate?
A CNC machined base plate is a precision-manufactured component used to support, align, and mount equipment, machinery, fixtures, or assemblies. CNC machining ensures accurate dimensions, flat surfaces, and precise hole locations, making base plates ideal for industrial, automation, robotics, aerospace, and electronic applications.
What materials are commonly used for base plates?
Base plates can be machined from a wide range of materials depending on the application requirements. Common choices include aluminum alloys (6061, 7075, MIC-6), carbon steel, stainless steel (304, 316, 17-4PH), brass, copper, and engineering plastics such as PEEK, Delrin, PTFE, and Nylon.
What tolerance can be achieved on a machined base plate?
Standard machining tolerances are typically ±0.05 mm (±0.002″). For precision applications, tolerances as tight as ±0.01 mm (±0.0004″) can be achieved depending on part geometry, material, and size requirements.
How is flatness controlled during machining?
Flatness is controlled through optimized machining strategies, stress-relief processes when required, precision fixturing, and final inspection. For critical applications, surface grinding or additional finishing operations can be performed to achieve tighter flatness specifications.
