About Us

Hotar Machining Co., Ltd. is a professional global manufacturer and supplier specializing in high‑precision custom CNC machined parts. Rooted in precision engineering excellence, we dedicate ourselves to converting complex engineering designs into high‑tolerance industrial hardware, serving equipment manufacturers, system integrators and industrial R&D teams across the world.

Our comprehensive machining capabilities cover high‑precision CNC milling, multi‑axis turning, micro‑machining and integrated surface finishing solutions. We work with a full spectrum of industrial materials, including aluminum alloys, stainless steel, titanium, brass, tool steel, as well as high‑performance plastics like PEEK and POM. All our OEM components are fully customized and manufactured in strict accordance with clients’ technical specifications to meet diverse industrial application demands across robotics, automation, medical, aerospace and new‑energy sectors.

Advanced Production & Metrology Equipment

To deliver consistent ultra‑precision output, we have built a complete closed‑loop quality system supported by in‑house production facilities and an independent constant‑temperature, anti‑vibration metrology lab. All parts are produced and inspected in compliance with ISO/ASME GD&T standards with fully traceable quality records.

Our production floor is fitted with multiple original Japan Brother U500 high‑speed precision machining centers. These units feature pre‑wired 5‑axis expandable capability, oil‑cooled thermally controlled spindles and full linear roller guides, delivering repeatable precision down to ±0.002 mm. The oil‑cooled spindle minimizes thermal deformation during long‑run production, while expandable 5‑axis functionality enables complex 3D‑curve and multi‑angle feature machining in a single clamping. High‑rigidity machine structures suppress cutting vibration to achieve superior surface finish for prototypes, small‑batch trials and mass‑volume orders alike.

For quality validation, our metrology lab deploys dual imported CMM systems: Hexagon Inspector S and German Wenzel LH series coordinate measuring machines. Boasting 0.0005 mm resolution and stable ±0.002 mm inspection accuracy, the dual‑CMM setup handles everything from miniature intricate components to large structural workpieces. Operating within a temperature‑controlled, vibration‑isolated environment, the equipment executes full dimensional and GD&T geometric tolerance verification. We conduct regular third‑party calibration, provide traceable bilingual inspection reports, and support FAI, batch sampling and final‑inspection data archiving.

We follow a strict closed‑loop manufacturing workflow: Precision Machining → In‑process Check → 3D Full Inspection → Data Verification → Qualified Delivery. This process guarantees batch‑to‑batch consistency whether you require prototype development or high‑volume production runs.

To streamline clients’ project processes, we provide one‑stop Design for Manufacturability (DFM) verification services. Clients can submit CAD files in STEP, IGES, DWG formats or design drawings, and our professional engineering team will conduct in‑depth evaluation of tolerance rationality, processing scheme and material adaptability prior to production. This effectively fixes potential design defects, optimizes production costs and accelerates product time‑to‑market.

Adhering to the core philosophy of “TURN COMPLEX DESIGNS INTO PERFECT HARDWARE”, Hotar Machining commits to becoming a trustworthy long‑term manufacturing partner for global clients. We offer highly flexible production services covering custom single‑piece prototyping, low‑volume trial production and continuous annual mass production, paired with efficient global logistics to match various project schedules.
