FAQ

Answers to frequently asked questions about purchasing, delivery and service for the QM700N.

What scenarios is the QM700N mainly used for? +

The QM700N is a manual notch maker for machining standard V-notches in plastic Izod/Charpy impact specimens: a 45°/R0.25 mm notch is milled in the specimen center to create stress concentration; it is the key preparation device for uniform, repeatable impact-strength data, suited to small-batch labs and shop-floor QC.

What are the core specifications of the QM700N? +

Per the specification table: cutting method manual, cutting speed 4 adjustable stages, slider LM-Guidance resolution ±0.003 mm, dimensions 575(W)×425(D)×435(H) mm.

How accurate is the notch cutter? +

With a Japanese-made carbide notch cutter, 45°±0.5°, tip R0.25±0.05 mm; the ultra-hard edge is wear-resistant, the machined surface is smooth with no thermal deformation, and notch geometry is highly consistent.

What is the role of the LM guide? +

The slider uses an LM linear guide with movement resolution ±0.003 mm; manual feed gives even groove depth, avoiding notch-depth deviation from hand shake and ensuring consistent notch geometry across the batch.

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 and specimen-molding standards.

How do I choose between it and the automatic QM700NA? +

The QM700N is a practical manual type for small batches and many specimen types; the QM700NA is an automatic type (5~3000 rpm adjustable, auto retract/stop, vacuum chip extraction) for high-volume, continuous QC-line preparation.

What is the lead time for standard models? +

Standard-model lead time is 3-8 weeks; special notch cutters and fixtures 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 guide-precision 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.
