Automatic Notch Preparation
Batch Preparation of Impact Specimens

The QM700NA automatic notch maker prepares standard plastic impact specimens. Blade speed 5~3000 rpm, feed speed, cutting direction and number of cuts are settable. A high-precision LM guide (±0.003 mm) and Japanese-made carbide blades ensure notch-size consistency; automatic retract/stop and vacuum chip extraction keep batch notch geometry uniform.

From batch QC to R&D experiments: notch geometry precision directly affects impact-test data. Automatic cutting plus vacuum extraction makes notch dimensions identical on every specimen; high batch-preparation efficiency and repeatable data make it a standard professional-lab setup.

Designed for batch notch preparation: automatic cutting plus vacuum extraction; reproducible impact-specimen notch precision.

FAQ

Answers to frequently asked questions about purchasing, delivery and service for the QM700NA.

What scenarios is the QM700NA mainly used for? +

The QM700NA is an automatic notch maker for automatic V-notch preparation of standard plastic impact specimens: notch-cutter speed, feed speed, cutting direction and number of cuts are set by material, with automatic vacuum chip extraction, batch-machining ASTM/ISO standard specimens; suited to automotive plastic-part and electronic-housing QC lines.

What are the core specifications of the QM700NA? +

Per the specification table: cutting method automatic, cutting speed 5~3000rpm, slider LM-Guidance resolution ±0.003mm; dimensions 680(W)×425(D)×430(H) mm.

How is automatic control achieved? +

Digital-indicator controlled; preset notch-cutter speed, feed speed, cutting direction and number of cuts by material; when machining is complete the cutter head automatically retracts and stops, with a double-lock adapter to prevent loosening.

What is the vacuum extraction for? +

The Auto Vacuum System simultaneously sucks away plastic chips during cutting, preventing chips from sticking to the blade and specimen surface and causing secondary scratching; it keeps the notch surface clean and uncontaminated.

Which test standards are supported? +

The machined specimens are suitable for ASTM D256, JIS K7110, ISO 179, ISO 180, ISO 294 and other plastic-impact specimen preparation standards.

How do I choose between it and the manual QM700N? +

Choose the QM700N practical manual type for small batches and many specimen types; choose the QM700NA automatic type for high-volume, continuous preparation with high repeatability, with ASTM and ISO standard fixtures for fast specimen changeover.

What is the lead time for standard models? +

Standard-model lead time is 3-8 weeks; special fixtures and vacuum-system options follow the confirmed contract lead time.

How are certification and after-sales service secured? +

The equipment carries CE / ISO 9001 system certification; notch-depth and speed calibration before delivery; after-sales support provides 2 hours emergency response, on-site installation and commissioning by certified engineers, and full-machine 1-Year Warranty with lifetime software upgrades.
