Precision CNC Turning & Turn-Mill Manufacturing

We manufacture custom fasteners, shoulder parts, pivot shafts, threaded shafts, sleeves, bushings, spacers and related OEM components. The examples on this page show existing geometries. For your order, the approved drawing defines the dimensions, material, mating interfaces, surface condition and acceptance requirements.

CNC turning primarily creates rotational features such as outside diameters, shoulders, faces, bores and threads. Turn-mill machining combines turned geometry with suitable cross-holes, slots and flats. Process planning connects the complete feature set to workholding, tool access and inspection references, including any additional operations the part needs.

Yes. Our CNC turning and turn-mill capabilities support parts combining rotational geometry with milled details. Show the position and orientation of cross-holes, flats or slots relative to the drawing datums. Those relationships, together with access and clamping requirements, determine the machining sequence and inspection plan.

Material options include 304 and 316 stainless steel, 6061 and 7075 aluminum, carbon and alloy steels, and drawing-specified titanium grades such as TC4 or Ti-6Al-4V. Specify the applicable standard, stock condition or temper, treatment and documentation requirements. Material selection must match the component's geometry and intended service.

Yes. Include the thread standard, size, pitch, tolerance class and effective engagement length. For blind internal threads, show hole depth and bottom clearance separately from usable thread length. Identify the mating thread and any treatment or masking requirement so that acceptance concerns the supplied, finished connection.

Tolerance capability depends on the feature, size, material, wall section, treatment and inspection conditions. Send the drawing with its functional fits and geometric requirements so we can confirm the production and measurement approach. A diameter tolerance does not replace separate requirements for roundness, position, straightness or runout.

Datums give manufacturing, assembly and inspection a common reference. Mating-part information shows which diameters locate, which faces seat and where clearance is needed. This helps connect shoulder positions, thread engagement and cross-feature locations to the actual assembly, rather than evaluating each dimension as an isolated number.

We manufacture sleeve and spacer geometries. Thin-wall requirements need a review of wall thickness, bore depth, material and clamping because the part can change shape when released. Show the functional surfaces and finished dimensions, including the measurement condition, so workholding and inspection address the supplied part.

Treatments can change the size or surface condition of mating features. Specify which dimensions apply after treatment, especially bores, bearing seats and threads. Define treated and masked surfaces and any permitted subsequent machining. Finish appearance, edge condition and surface texture should also be part of the acceptance criteria.

Yes. We support prototypes, small batches and repeat production. State what the sample must establish, such as fit, geometry or assembly clearance, along with material and critical requirements. Include both sample quantity and expected production quantity so the quotation can distinguish preparation work from subsequent manufacturing.

Repeat orders reference the approved drawing number, revision, material and finished requirements. Identify any changes to dimensions, treatment, inspection, mating parts or packing before production is arranged. Sample approvals and agreed records provide the order reference; an unchanged part name alone is insufficient to control an engineering change.

The certificate names Guangdong Pinshang Hardware Products Co., Ltd. and covers its ISO 9001:2015 quality management system for the production of hardware screws and nuts. It does not certify every product individually. The original certificate and scope are available above, together with the issuer and validity dates.

Yes. Share a BOM identifying each part number, drawing revision, material and quantity per assembly. Include mating drawings, finished interface requirements and the required packing relationship. Our fastener system manufacturing process connects shafts, sleeves, spacers, nuts and other related components to the same project definition.

Send the drawing and revision, material and condition, sample and production quantities, finish and critical acceptance requirements. Add mating drawings or a BOM where relevant, plus requested timing and inspection documents. If a detail remains undecided, identify it clearly so the quotation records the agreed basis.
