Why use precision grinding for sputtering components?

Precision grinding achieves tight tolerances (+/-0.002mm), superior surface finish (Ra <=0.4um), and excellent flatness - all critical for vacuum sealing and proper component fit.

What is the maximum part size you can machine and grind?

1500mm x 500mm x 500mm - suitable for large sputtering chamber components, backing plates, and custom parts.

What thread types can you machine?

NPT, NPTF, BSPP, BSPT, UN/UNF/UNC, Metric, and custom threads.

Can you perform passivation for 416 parts?

Yes - passivation per ASTM A967 standard is available to enhance corrosion resistance.

Send drawings (PDF/STEP/IGS/DWG) with: material (416), heat treatment requirement, grinding tolerance, surface finish requirement, and quantity. No drawing? Send a sample, photo, or sketch - free engineering support.

What is your lead time for precision ground 416 components?

Sample (1-10 pcs): 10-15 days. Batch production: 2-3 weeks. Rush service - please inquire.

Do you offer samples?

Yes. Sample fee is fully refundable upon mass production order. Sample includes full inspection report and material certificate.

What after-sales support do you offer?

30 days to report any issue; solution within 7 days. Click 'Contact Supplier'.

AI-Powered supplier vetting

SummaryDongguan Guanneng Automation Technology Development Co., Ltd. is a China-based combined business entity identified in one record as a trade company, operating in Dongguan, Guangdong. It reports more than 15 years of machining-industry experience, while the company establishment date provided is 2018. Its stated capabilities include CNC machining, milling, grinding, wire cutting, turning, testing, assembly, and after-sales service. The supplier reports its own factory, multiple production lines, more than 10 production lines, and ISO9001:2015 certification. It serves machining, biomedical, automotive, semiconductor, automation, and petroleum machinery industries, and exports to East Asia, Europe, and North America. Lead times are stated as within 15 working days in both off-peak and peak seasons. Evidence is insufficient to assess financial credibility, innovation output, formal outsourcing or contract controls, overseas warehousing, traceability, or named customer cases. The audit record is dated November...

CertificationsThe supplier reports holding an ISO9001:2015 certificate and describes a dedicated quality control department and strict ISO9001-based production management system. A BV audit is also recorded for November 9, 2023 through November 8, 2024, although the audit result is listed as 0 without an explained scale.

After-Sales capabilityThe company description explicitly includes after-sales service among its integrated activities and states that it serves domestic and overseas enterprises. However, the records provide no specific response process, service coverage, repair policy, or overseas service infrastructure; overseas warehouse and showroom capabilities are marked unknown.

Production capacityThe supplier reports more than 15 years of machining-industry experience, its own factory, multiple production lines, and more than 10 production lines. It lists CNC machining, milling, grinding, wire cutting, and turning capabilities, serves several industrial sectors, and states lead times within 15 working days in both peak and off-peak seasons.

Customization capabilityThe product and service descriptions cover precision CNC machining, CNC turning, grinding, wire cutting, machinery parts, testing, and assembly. The supplier states that its production lines can meet different product needs and requirements, supporting customization, although no detailed engineering workflow, tolerance range, tooling policy, or sample-development evidence is provided.

Product Q&A

Q:Are you a manufacturer or trading company?

We are a direct manufacturer - 2,000 sqm, 17 years of experience, 30+ CNC machines and precision grinding equipment, ISO9001, 3D CMM.

Q:What is 416 stainless steel?

416 (UNS S41600) is a martensitic free-machining stainless steel with 12-14% chromium and sulfur added to enhance machinability. It was the first free-machining stainless steel ever developed.

Q:What is the machinability of 416?

416 has the highest machinability of any commonly available stainless steel, at approximately 85% of free-machining carbon steel.

Q:What precision grinding tolerances can you achieve?

We achieve +/-0.002mm on critical diameters and features, with surface roughness down to Ra <= 0.2um.

Q:Is 416 suitable for vacuum applications?

Yes. 416 is used in vacuum chambers and sputtering systems. For UHV applications requiring extremely low outgassing, 316L is typically preferred.
