Custom Aluminum CNC Machined Plate with Recessed Pocket and Central Interface
Custom Aluminum CNC Machined Plate with Recessed Pocket and Central Interface
Drawing-based CNC machining for an aluminum plate with a recessed pocket, central bore feature, threaded mounting holes, curved reliefs and finished edges. Shenzhen Perfect Precision Products Co., Ltd. reviews your drawing, material, tolerance, finish and quantity before confirming the process and quotation.
A machined plate designed around the details that affect fit
The pictured component appears to be a custom aluminum plate or mounting component. Its top face contains a recessed pocket with rounded internal corners, a central circular opening surrounded by a regular serrated or tooth-like rim, and several threaded mounting holes. The outside profile includes curved reliefs and chamfered edges. These visible features point toward CNC milling with drilling, tapping and multi-operation machining, but the final product function must be confirmed from your engineering documents.
The central feature is intentionally described in neutral terms. A photograph cannot confirm whether it is an internal spline, serrated bore, gear-like interface or another custom profile. The drawing should define the mating datum, profile, bore size, depth, orientation and clearance requirements before production.
Complex pocket geometry
Rounded internal corners, pocket depth and tool access are reviewed during quotation so the machining route matches the design.
Defined mounting interface
Threaded holes and the central opening are quoted from the drawing, not treated as generic holes or unverified standard features.
Prototype to production
The documented service model supports prototype, pilot and production programs subject to drawing, material, capacity and inspection review.
Documented quality resources
The company documents six QA/QC inspectors and five testing instruments, including CMM and 2D measuring instruments.

Why the machining details matter
Central interface definition
A central opening with a serrated or tooth-like rim can determine how another component locates, rotates or transfers load. The visual cannot establish the profile standard. The buyer should provide a drawing that identifies the profile, bore size, depth, angular orientation, datum and mating clearance. This allows the feature to be reviewed against the assembly rather than quoted as a generic hole.
Pocket and curved relief review
A recessed pocket with rounded corners affects cutter diameter, tool reach, corner radius, chip evacuation, workholding and inspection access. Curved end reliefs can also influence fixturing and the number of setups. Engineering review can identify areas where a relaxed non-critical tolerance or a revised radius may reduce cost without changing the intended function.
Threads and assembly fit
Threaded holes require a defined standard, pitch, depth and positional tolerance. Chamfer, burr removal and cleaning requirements matter when fasteners must seat consistently. These call-outs should be tied to the selected datum scheme so inspection records measure the features that actually affect assembly.
Manufacturing and quality workflow
- Drawing and DFM review: engineers review the 2D drawing, 3D model, datums, pocket, central interface, threads, finish, quantity and inspection requirements.
- Material verification: the alloy and temper are recorded, with material certificates or test reports available when requested and agreed.
- CNC machining: the documented facility supports 3/4/5-axis CNC machining, CNC milling, CNC turning and mill-turn work. This plate is likely to use milling, drilling and tapping, subject to review.
- Deburring and edge finishing: burrs around threads, the central interface, pocket edges and external profile are addressed according to the drawing.
- Surface treatment: anodizing, powder coating, polishing, plating and other finishing routes are available through in-house or qualified partner arrangements as applicable.
- Dimensional inspection: six QA/QC inspectors and five testing instruments, including CMM and 2D measuring instruments, are documented. The inspection plan should identify critical dimensions.
- Final inspection and packaging: incoming, first-article, in-process or sampling, and pre-shipment inspection stages are documented. Packaging and protection requirements should be included in the RFQ.
Factory capability and buyer support
Shenzhen Perfect Precision Products Co., Ltd. is documented as a custom OEM/ODM manufacturer founded in 2012 in Shenzhen, China. The supplied company information identifies 79+ machines, more than 100 professional staff and monthly capacity exceeding 300,000 pieces across its operations. The company supports CNC machining, injection molding, sheet metal, casting, forging, rapid prototyping, gears, linear modules and finishing coordination.
The verified quality information supplied for the company identifies ISO9001:2015 and ISO13485:2016, together with onsite verification by TÜV Rheinland. ISO14001, ISO45001, AS9100 and IATF16949 are listed in the source material as requiring current-document verification and should not be presented as confirmed certifications without original evidence.
The company documents prototype, pilot and production support, engineering review, DFM feedback, revision control and drawing confidentiality. Simple CNC prototypes may be possible in 1–3 days, while standard prototypes and production orders require confirmation of material, complexity, finish, inspection, quantity and current capacity. These are indicative capabilities, not a fixed promise for this component.
For international supply, logistics partners can coordinate express, air, sea and door-to-door options. Transit, customs, duties and arrival dates depend on destination, carrier and Incoterm. Customer drawings and product information are treated as confidential business information, and an NDA can be requested before sensitive design data is exchanged.
Design review points for a reliable quotation
A photograph communicates the overall form, but a production quotation depends on the relationships between features. For this plate, the primary datum should be connected to the surfaces that locate the part in the buyer’s assembly. The location of the central interface, the threaded holes and the recessed pocket should be dimensioned from that datum rather than from unrelated outside edges.
If the central feature engages a mating shaft, hub or insert, include the mating component or its controlled dimensions. Profile definition, angular orientation and clearance can affect whether the part assembles smoothly. If the feature is only a clearance opening, state that clearly so the supplier does not apply an unnecessarily demanding profile or inspection method.
For threaded holes, identify whether each hole is blind or through, and state the usable thread depth rather than only the drill depth. Include the fastener standard when known. A clear edge-break requirement helps prevent sharp edges while preserving the material around the threads. For the pocket, identify floor flatness, corner radius, wall condition and any surface appearance requirement.
These details support a practical DFM review. The goal is not to tighten every dimension, but to protect the features that control assembly while avoiding unnecessary machining time, inspection cost and rework risk on non-critical surfaces.
