Overview
XCM CNC is a Shenzhen Acrylic (PMMA) CNC machining factory with batch-supply capability for transparent windows, light-guide parts, and display components. Certified to ISO 9001, ISO 13485, and IATF 16949, the factory uses Mazak, Brother, and other equipment to mill and turn cast acrylic, extruded acrylic, and optical-grade PMMA. Before batch supply, it assesses material-lot management, polishing routes, and export packaging protection. MOQ is one piece, standard lead time is 10-15 days, and samples take 3-7 days.

Acrylic (PMMA) Large-Format Equipment Capacity for China Supply
The Qiaofeng 3016-4A offers 3000 x 1600 x 1400 mm milling travel and a Shenyang CK61125 lathe covers Dia. 1250 x 2000 mm turning, allowing direct scheduling of large PMMA display panels and transparent equipment covers. Regular +/-0.03 mm tolerance is included in base pricing; +/-0.005 mm precision features are assessed separately from the drawing. Fixture datums and deformation control for large transparent parts are confirmed before scheduling.
PMMA Batch Traceability and Material-Lot Routing
Material-lot numbers on repeat PMMA orders are linked to each part inspection record, and cast versus extruded sheets are controlled separately by supplier batch number. Hexagon CMM dimensional reports establish inspection datums on the first delivery; later batches recheck critical dimensions and 0.015 mm position against the same datum. When batches change, engineering confirms consistency of sheet-thickness tolerance and light-transmission direction.
Acrylic (PMMA) Surface Protection Routing for Export Shipments
Export PMMA parts receive cosmetic reinspection after polishing, protective film on transparent faces, and then isolation packaging. After edge polishing, a WanHao VMS-3020G video measuring machine rechecks critical holes and outer dimensions; Ra 1.6 um mating faces and 0.02 mm coaxiality on selected features are confirmed before packing. DHL, FedEx, UPS, and sea freight are available, with wooden-crate reinforcement for large displays.
PMMA Repeat-Order Inspection and Consistency Control
Repeat PMMA orders continuously monitor +/-0.03 mm regular dimensions and polished-face appearance using the inspection datum confirmed on the first article. Light guides, viewing windows, and display parts are reinspected with TRIMOS 600L height-gauge and CMM support; critical-dimension sampling is adjusted for order volume. Material certificates and inspection reports ship with every batch for customer receiving checks.

Applications
Optical Light Guides and Clear Lens Supply Parts
Typical parts: Light Guide Plate, Prism, Clear Lens.
PMMA high light transmission (92 percent), low birefringence, and polishing compatibility suit batch supply of light guides, prisms, and clear lenses. Qiaofeng 3016-4A mills large light-guide plates, Brother machining centers process small prisms and lenses, and material lot numbers are linked to inspection reports order by order for repeat-order traceability.
Medical Viewing Windows and Transparent Housing Batches
Typical parts: Viewing Window, Flowmeter Housing, Transparent Guard.
PMMA is transparent and easy to polish, making it suitable for repeat production of viewing windows and transparent flowmeter housings. After the first batch establishes inspection datums for sealing grooves and mounting holes, later batches are sampled to the same standard. Material certificates and FAI reports can be supplied under the ISO 13485 system.
Laboratory Viewing Cells and Transparent Container Supply Parts
Typical parts: Cuvette, Viewing Cell, Transparent Container Part.
PMMA transparency and mirror polishing support continued supply of cuvettes and viewing cells. Video measurement rechecks internal wall thickness and locating-hole size after cavity polishing. When material lots change, light-transmission direction and stress state are revalidated to reduce batch-to-batch variation.
Lighting Covers and Transparent Display Panels
Typical parts: Diffuser Plate, Lighting Cover, Display Window.
PMMA light-guiding and diffusion characteristics suit factory supply of lighting covers, diffuser plates, and large display windows. A 3000 x 1600 mm travel can machine large panels in one setup; protective-film application and wooden-crate reinforcement are arranged before shipment to reduce surface damage in transit.
Why Choose Us
Complete Quality System and Equipment Coverage
The factory organizes quality processes around ISO 9001, ISO 13485, IATF 16949, and GJB9001C, using DMG, Mazak, Matsuura, Brother, and other equipment for acrylic transparent parts, light-guide parts, and window parts. For optical-grade PMMA display parts and medical-device windows, drawing review can confirm tools, polishing, stress cracking, and protective-packaging requirements together.
Broad Size Coverage
Machining can cover needs from small connectors to large structural parts, including PMMA light guides, transparent windows, small prisms, larger display structures, viewing windows, and transparent equipment covers. Three-axis travel reaches 3000 x 1600 x 1400 mm and turning diameter reaches 1250 mm; the actual plan remains subject to fixturing, polishing, stress control, and transport-protection requirements.
Tiered Equipment Strategy for Low-Cost CNC Machining, Quality-Assured Production
XCM CNC uses CNC equipment from mainland China, Taiwan, Japan, and Europe or the United States. Lower-tolerance operations can run on domestic or Taiwan machines, while high-precision work uses imported equipment such as DMG and Mazak. Matching equipment to actual precision needs avoids using high-hour machines for simple operations and reduces cost while meeting drawing requirements.
Batch Control and Repeat-Order Stability
For repeat PMMA supply, material batch number, machining parameters, and inspection datum are filed by order so later batches can reuse the same machining plan. When lots change, engineering checks sheet-thickness tolerance and supplier consistency; critical-dimension sampling is adjusted to customer acceptance requirements to reduce batch variation.
Export Packaging and Logistics Coordination
Before shipment, PMMA transparent parts undergo cosmetic reinspection, protective-film application, foam isolation, and corner protection as a standard sequence. Large display parts and viewing windows use reinforced wooden crates. DHL, FedEx, UPS, and sea freight are supported; packaging is adjusted to transparent-face location and acceptance requirements, with T/T, PayPal, and Western Union payment supported.
FAQ
What is the minimum order quantity and lead time for Acrylic CNC parts?
MOQ is one piece, with no minimum-order barrier. Standard lead time is 10-15 days, assessed by part complexity and order quantity; samples can be delivered in 3-7 days. Urgent orders can receive prioritized scheduling after drawing confirmation.
How do you track material lots for repeat PMMA production orders?
Supplier batch number, sheet-thickness tolerance, and light-transmission direction for every PMMA sheet are recorded on incoming inspection records and linked to the machining order and inspection report for each part. Material state is revalidated at batch changes, and order-filed data can be retrieved for traceability.
Why do Acrylic parts crack after machining or polishing?
Can your factory supply large-format Acrylic display panels over 1 meter?
Milling travel of 3000 x 1600 x 1400 mm can machine PMMA display panels and transparent equipment covers over one meter in one setup. Large parts require assessment of sheet flatness, fixture-deformation control, and transport protection; wooden crates with internal foam support are used for shipment.
What inspection reports come with each batch of Acrylic parts?
Standard supply includes a dimensional inspection report. Precision parts can include CMM and FAI reports, and material certificates are provided to order requirements. Repeat orders use the first-batch confirmed inspection datum, with critical-dimension sampling adjusted to lot size and customer requirements.
How do you handle Acrylic batch transitions when material suppliers change?
When suppliers change, engineering compares thickness tolerance, light transmission, and machining behavior of old and new sheet lots and may arrange a small trial cut. Trial parts are checked against the original inspection datum for dimensions and polish result before formal production switches.
