Wenlio Machining Service
Broaching
Extensive inventory of broaches in various sizes and shapes, making us the ideal choice for urgent order.
Grinding
These services include ID/OD, gear or spline, thread, jig or surface grinding.
Hobbing
With over 10,000 hobs in stock, we likely already have the tooling available for your custom order.
EDM -Wire and Ram
Especially well suited for operations requiring high accuarracy and low-count quick-turnaround part runs.
Laser cutting
Producing for small batches, thin-plate gears (typically <20mm), non-standard gears.
Shaping
Shaping capacities range from 0 to 40″ diameter, and pitches from 1 to 1000.
Shaving
Constructed with a heavy-duty frame for stability and often features automated loading systems.
milling
4th axis capabilities, hold tolerances within .0002″ linear and 10 arc second rotary repeatability.
Quality Control
Prior to every shipment, we conduct the following tests and provide complete quality reports for these gears.:
1. Bubble drawing
2. Dimension measurement report
3. Material certification report
4. Heat treatment testing report
5. Accuracy measurement report

Packaging
Step 1 – Anti-rust: We wrap each gear with VCI anti-corrosion paper / bag to protect it from rust during shipping.
Step 2 – Inner protection: The wrapped parts are placed properly to avoid scratches and impact.
Step 3 – Carton packing: Then we pack them into strong export cartons (logo printing is available).
Step 4 – Crate & pallet: Cartons are loaded into a reinforced plywood crate with partitions, and fixed on a pallet.
Step 5 – Secure & label: The crate is sealed, strapped, and labeled, ready for sea/air shipment.
We can also provide custom printed color boxes and logo customization (carton, color box, crate marking, labels).
Note: Please ensure the logo/design is authorized by you; if it involves any third-party brand, we will need written authorization to avoid IP risks.
FAQ
Are helical gears a good fit for machine tool servo drives?
Often yes. Helical gears are used in servo drives and reducers for smoother engagement at speed. Share your speed range, torque, and backlash requirement so we can align tooth quality, heat treatment, and inspection to your performance goal.
Can you quote from a prototype drawing and flag manufacturability risks?
Yes. Send your latest drawing and tolerance priorities. We will highlight critical items that drive cost or lead time, such as tight runout datums or interface fits, and suggest practical adjustments without changing functional intent.
What information should be included in the RFQ?
Module/DP, tooth count, helix angle, face width, pressure angle if known, bore/spline details, target backlash, speed/torque, lubrication method, and quantity. For servo systems, mention acceleration profiles because they affect tooth loading.
What heat treatment options do you support for machine tool gears?
Heat treatment depends on wear target and duty cycle. If you have surface hardness and core requirements, provide them. If not, we can propose a suitable route for quotation based on your speed, load, and expected service life.
What inspection evidence can you provide for incoming QC or PPAP-style needs?
We can provide dimensional and tooth measurement evidence, hardness checks, and other records as requested. Share your documentation list early so we can plan the inspection package correctly.
How can we reduce wear in compact reducers?
Wear control is usually about correct material pairing, heat treatment, surface finish, and lubrication. Tell us oil type, operating temperature, and contamination risk. With that, we can recommend a realistic finish and inspection focus for your application.
