Product Overview

The KR‑814A lever‑action circular punch cutter is a manual sampling tool built for GSM (gram‑per‑square‑meter) quantitative testing. It punches perfectly‑defined round swatches for cotton, wool, silk, linen, synthetic‑fiber woven and knitted textiles. Beyond fabric materials, this tool is also well‑suited for preparing test specimens from leather sheets, paper‑board and thin aluminium foil.

Powered by labour‑saving lever‑spring mechanics, it is capable of cleanly cutting multi‑layer stacked materials in one single pressing motion. This drastically cuts down manual‑cutting workload and improves throughput for production‑floor QC stations and material laboratories. Interchangeable cutting dies deliver three standard sampling‑area selections: 10 cm², 50 cm² and 100 cm² to satisfy varied test‑protocol requirements.

Core Product Competitive Advantages

Swap‑Able Cutting‑Dies for Multiple Sampling Areas The main machine host supports quick‑swap cutting‑ring dies for 10 cm², 50 cm² and 100 cm² specimen sizes. Operators can switch sampling dimensions without purchasing separate units, optimising laboratory‑tool investment.
Premium Imported‑Steel Circular Cutting‑Ring High‑grade imported tool‑steel forms the punch die edge. It maintains sharpness for long‑term heavy‑duty usage and generates burr‑free, distortion‑free circular swatches. Consistent specimen geometry prevents weighing errors that would skew final GSM calculation results.
Ergonomic Spring‑Return Lever‑Press Mechanism Human‑friendly long‑handle lever paired with built‑in return spring. Users complete full punch‑cutting action with one‑hand force. No electric power source required, so the cutter can be deployed on any flat work‑surface inside QC‑rooms or testing labs.
Robust Light‑Weight Cast‑Aluminium Main‑Frame High‑strength cast‑aluminium construction balances mechanical rigidity and portability. Compact footprint saves valuable bench‑top space. At only 8.4 kg net weight, the unit can be easily relocated between different workstations.
Consumable‑Based Protection for Cutting Edge Replaceable protective base pads shield the sharp steel cutting‑ring at every punch stroke. Timely pad replacement extends die service‑life and preserves clean cutting quality for high‑frequency batch‑sampling assignments.

Standard Complete Test Operating Workflow

Pre‑Test Preparation Position the sampler on a solid, flat hard workbench. Fit the target‑size cutting die. Install an intact protective rubber / PVC base pad onto the bottom platform. Lay the textile, leather or foil sample flat over the pad and smooth away wrinkles.
Specimen Positioning Align the intended sampling zone directly underneath the circular cutting‑ring. Ensure no debris or creases sit between the raw‑material sheet and the protective base pad.
Perform Lever‑Driven Punch‑Cut Stabilise the machine body with one hand; steadily push down the operating lever until the cutting‑ring fully penetrates the stacked material layers.
Retrieve Qualified Circular Specimen Release the lever; the integrated spring automatically lifts the cutting die upwards. Remove the punched‑out circular swatch. Inspect edges for burrs or incomplete cuts; discard defective pieces and repeat punching if needed. Good‑quality samples are ready for weighing on analytical balance for GSM calculation.
Post‑Operation Housekeeping Clear fabric lint and material scraps from cutting‑ring and base pad. Inspect base pad for cuts and abrasion; swap for fresh pad when heavily worn. Keep the whole instrument stored inside dry conditions when not in regular use.
