Precision CNC machining.精密CNC加工
Forty-two machining centers across three- and four-axis milling, 4.5-axis indexed, turning, and Swiss-type platforms, staffed by a dedicated machining engineering team. Production tolerances held from prototype through fifty-thousand-unit annual programs across aluminium, titanium, stainless, and engineering plastics.
What is actually in our machining facilities.我们的加工厂房里到底有什么
Forty-two machining centers and lathes, organised into four bays by platform and material profile. Equipment count and inventory shared openly — every program quote is grounded in real spindle availability, not aspirational capacity. 四十二台加工中心与车床，按平台与材料属性划分为四个工区。设备数量与库存透明公开——每个项目报价都基于真实主轴产能，而非夸大的理论产能。
4.5-axis indexed machining.4.5轴定向加工
Six trunnion-table machining centers run in 3+2 indexed positional mode — the rotary axes position the part, lock, and the cutting motion stays 3-axis. Faster setup, simpler programming, and complete coverage of complex parts in a single fixturing — without the cost premium of full simultaneous 5-axis. 六台摇篮式工作台加工中心以 3+2 定位方式运行——回转轴将零件定位锁定，切削运动保持三轴。装夹更快、编程更简单、复杂零件一次装夹全部完成——没有完整五轴联动的成本溢价。
Five faces, one fixturing, one datum.五个面，一次装夹，同一基准
Aerospace structural brackets, optical housings, and instrument bodies have features on five faces. On a 3-axis platform, each face requires a re-fixture — and every re-fixture introduces datum drift. With trunnion indexing, the part lands on the fixture once; the table rotates and tilts to expose each face, and every feature is cut from a single datum. 航空航天结构支架、光学外壳、仪器机身在五个面均有特征。在三轴平台上，每个面都要重新装夹——每次重装都引入基准偏差。使用摇篮式定位轴时，零件只装夹一次；工作台旋转倾斜以展露各面，所有特征均以单一基准切出。
What 4.5-axis (3+2) gives up versus full simultaneous 5-axis is contour following on organic surfaces — impeller blades, blended airfoils, complex freeform geometry. For the parts a contract manufacturer sees most often — prismatic housings, brackets, valve bodies, fittings — 3+2 delivers the coverage benefit at a substantially lower programming and tooling cost. When organic 5-axis surfaces come up, we say so and route the work to a partner shop.
Aerospace fittings, optical housings, monolithic brackets.航空配件、光学外壳、整体支架
Parts that previously required three to five fixturings now run in one. We typically see 30–50% cycle time reduction on parts moved from 3-axis to 4.5-axis indexed, and equally important, the scrap rate at the FAI stage drops because every face references one datum.
Swiss-type turning.瑞士型车削
Eight Swiss-type CNC lathes for small-diameter, high-precision turned parts. Bar-fed through a guide bushing positioned millimetres from the cutting tool — the cut zone has no overhang, and parts hold tight tolerance even at 30:1 length-to-diameter ratios. 八台走心式 CNC 车床，用于小直径高精度车削件。棒料经导套送料至距刀尖仅数毫米处——切削区无悬伸，即使在 30:1 长径比下仍能保持高公差。
Why Swiss-type holds tolerance where other lathes don't.瑞士型车床在其他车床达不到的地方守得住公差
On a conventional lathe, the bar stock projects from the chuck like a cantilever — the further from the chuck the tool cuts, the more deflection. On Swiss-type, the bar slides through a guide bushing and the tool always cuts within a few millimetres of that bushing. Effective rigidity is constant along the part length. 在普通车床上，棒料从卡盘悬伸而出——刀具越远离卡盘，挠度越大。在走心机上，棒料穿过导套，刀具始终在距导套几毫米处切削。零件全长上的有效刚性保持一致。
For pivots, optical retaining rings, dowel pins, fasteners, and shafts where surface finish and concentricity over a long length matter — this is the right machine. 用于轴销、光学挡圈、定位销、紧固件、长轴件——只要表面光洁度与长距离同心度有要求，这种设备就是正确选择。
Sophisticated fixture design.精密夹具设计
A well-designed fixture is where part cost actually comes out of high-volume programs. We design fixtures in-house, machine them in the same complex, and qualify them through FAI before any production lot runs. A dedicated fixture engineer sits with the machinists — iteration is measured in days, not weeks.
Designed, machined, and qualified across one complex.设计、加工、资格认证同处一厂
Generic vises and parallels work for prototypes; for production they are slow, inconsistent, and demand operator skill that doesn't scale. Custom fixtures — soft jaws contoured to the part, hydraulic clamping on production lines, modular bases that swap in seconds — turn a three-minute setup into thirty seconds and let a junior machinist load the same part as accurately as a senior.
Every program with a forecast volume above pilot scale gets a fixture review. The design lives in our system, gets revision-controlled alongside the part drawing, and is qualified through a fixture-FAI before the first production lot ships. 凡是预测量超出试产阶段的项目都做夹具评审。夹具设计存档于我们系统中，与零件图纸同步版本控制，并在首次量产出货前通过夹具首件检验。

Custom grades sourced from qualified mills on program request. 常用规格的热处理与认证材料常备库存。按项目要求每批出货均记录厂商证书、炉号与批次追溯。特殊规格根据项目需求从合格供应商采购。
General-purpose aerospace and structural aluminium. Excellent machinability, weldability, and corrosion resistance.
High-strength aerospace aluminium. Used where part stiffness and fatigue resistance matter — brackets, mounts, gimbals.
Aerospace skin alloy with high fatigue resistance. Less corrosion-resistant — typically clad or anodized.
Marine-grade aluminium. Good formability, excellent corrosion resistance. Used on housings exposed to wet environments.
Precipitation-hardening stainless. Heat-treatable to high strength while maintaining corrosion resistance. Aerospace and tooling staple.
Low-carbon austenitic stainless. Standard for medical, food, and chemical applications. Good weldability and corrosion resistance.
General machining stainless (303) and standard food-grade (304). Free-machining grade is the workshop's go-to for fasteners and pivots.
Workhorse aerospace titanium. Strength-to-weight ratio of steel at half the density; calls for specialised tooling and feeds.
Commercially pure titanium. Used where biocompatibility or chemical inertness matters more than strength.
Chrome-moly alloy steel. Used for shafts, axles, and high-load fittings. Through-hardenable for tooling applications.
Nickel-chromium superalloy. High-temperature aerospace and turbine work. We machine on dedicated 4.5-axis bays with rigid production fixtures.
High-performance thermoplastic. Self-lubricating, high temperature, chemical-resistant. Used in optical and medical assemblies.
Acetal homopolymer. Excellent dimensional stability, low friction, good machinability. Common for gears, bushings, low-load mechanical parts.
Ultra-high molecular weight polyethylene. Wear surfaces, sliding components, low-friction guides.
PTFE for seals and chemically inert components; Torlon for high-temperature, high-strength engineering applications.
Cured carbon-fiber-reinforced epoxy plate. PCD-tooled CNC trim and feature machining for limbs, drone arms, optical shrouds.
Glass-fiber-reinforced epoxy laminate. Excellent dimensional stability and electrical insulation. Machined for jigs, fixtures, archery limbs, electronic housings.
Solid bar, plate, or block from mill stock. Default starting form — most prototype and low-to-mid volume work begins here.
Near-net shape with directional grain flow. Higher fatigue strength for aerospace fittings, gimbal yokes, and structural brackets.
High-volume non-ferrous near-net parts. We finish-machine critical features, ports, threaded bores from as-cast blanks.
Constant cross-section profiles cut to length. Common on heat sinks, structural rails, and Picatinny-style platforms.
Complex shapes and larger parts. Investment for tighter as-cast tolerance, sand for cost on bigger geometry — both finish-machined.
Laser-cut blanks from sheet or plate stock, then formed and machined. Common for thin-wall housings and brackets.
Other grades — magnesium AZ31, brass C360, nickel alloys, additional engineering plastics — quoted on program request. Material certs and lot traceability supplied with every shipment as standard.
