Rectangular Machined Plate with Aluminum Mounting Plate and Three Circular Through-Holes

Dongguan Tongshunda Precision Technology (Dongguan, Guangdong, established 2023) CNC-mills aluminium mounting plates with three circular through-holes using boring & milling, four-axis horizontal machining centre, and surface grinding at their nearly 2,000 m² Dongguan facility, with hole true position, plate face flatness, and countersink angle verified per your drawing during in-process inspection; an aluminum mounting plate with hole position error displaces the mated component off the design centreline and introduces a bending moment in the fasteners, while face flatness above 0.05 mm causes the mounted module to rock. Alloy grade selection between 6061-T6 and 7075-T6 determines whether post-machining stress relief is required before final flatness grinding. Tongshunda serves aerospace, automation, drone, medical equipment, and robotics aluminum mounting plate applications, serving military, drones, and battery applications. Supply hole true position, face flatness, countersink dimensions, alloy grade, and anodising requirement with your enquiry.
