Product Overview

The KR‑513 protective‑glove cut‑resistance tester is professional PPE laboratory instrument for assessing anti‑blade‑cut performance of hand‑protection‑glove materials. Following the coupe‑test principle defined in EN 388, ISO 20344 and GB/T 20991‑2007, a rotating circular blade executes reciprocating horizontal travel with a constant 5 N vertical load pressing onto the fixed test‑specimen. Once the blade fully slices through the sample, the sensing circuit captures the event. Operators calculate cut‑resistance index by comparing cycle‑count data of test‑sample against reference‑calibration fabric, so as to assign corresponding mechanical‑protection‑performance grade for glove raw‑materials.

This compact benchtop unit fits daily quality‑control workflows. It is widely deployed in protective‑apparel manufacturers, labour‑safety‑goods R‑D departments and accredited third‑party testing‑laboratories for incoming‑material validation, finished‑glove batch inspection and high‑strength‑textile material‑formula screening.

Core Product Competitive Advantages

1. Standard‑compliant reciprocating rotary‑blade drive system Realises 50 mm fixed test stroke; maximum linear cutting speed reaches 10 cm/s. Rotary blade spins in opposite direction to travelling movement to simulate real‑world shearing‑cutting effect. The system maintains precise 5 ± 0.005 N vertical test‑load, fully meeting parameter requirements of international glove‑safety‑test‑normsИнфор….
2. Reliable automatic penetration‑detection module Conductive‑backing‑pad together with signal‑sensing circuit identifies exact moment when blade pierces through material. It automatically locks effective cutting‑cycle value, removing subjective judgement errors caused by manual visual observation.
3. High‑capacity six‑digit LCD preset cycle counter 6‑digit digital display records reciprocating cutting repetitions. Two stop‑modes are selectable: auto‑halt upon sample penetration, or auto‑stop after reaching user‑defined maximum cycles. Readings are clear and convenient for high‑volume batch QC testing.
4. Quick‑release rigid specimen clamping assembly Purpose‑designed sample‑fixture firmly holds glove‑material flat without slack, slippage or wrinkling during repeated cutting cycles. Quick‑clamp mechanism speeds‑up specimen replacement and improves lab‑testing efficiency.
5. Stable integrated benchtop mechanical‑frame Heavy‑duty welded cabinet structure effectively suppresses vibration generated during high‑speed reciprocating movement. Compact footprint adapts to ordinary laboratory work‑benches; simple front‑panel button‑control lowers operator‑learning threshold.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation Position tester on rigid horizontal lab‑bench. Inspect reciprocating transmission parts, blade mounting condition and penetration‑sensing circuit. Install qualified standard circular cutting blade and verify blade sharpness by using reference‑calibration fabric according‑to‑standard rules. Power‑on and run short idle stroke check. Cut glove‑material specimens into standard test dimensions.
2. Specimen Mounting Open sample fixture, lay specimen flat on conductive‑rubber backing‑pad. Tighten clamps to eliminate folds and material slack. Make sure sample will not shift during reciprocating‑cutting runs.
3. Parameter Configuration Set maximum allowable test‑cycle value on LCD counter. Choose stop‑trigger mode: auto‑stop on cut‑through detection or stop at preset cycle‑limit.
4. Run Reciprocating Cut‑Resistance Test Press start button. Rotary‑blade performs repeated back‑and‑forth cutting under constant vertical load. If blade pierces sample, detection‑system triggers immediate stop and retains final cycle‑reading. If no penetration occurs, machine stops automatically after hitting maximum‑cycle setting. Complete parallel test with reference‑fabric for index‑computation.
5. Data Processing & Result Recording Calculate cut‑resistance index by comparing test‑specimen cycle‑data against reference‑fabric results and confirm corresponding performance grade. Multiple replicate‑specimen tests are recommended to obtain statistically‑valid evaluation conclusion.
6. Post‑Test Tidying Remove tested sample. Inspect cutting‑blade for chipping or blunting; replace or re‑calibrate blade as required. Clear fibre debris from fixture and conductive‑pad surface. Reset counter‑settings for next‑batch‑testing. Periodically check test‑load accuracy and penetration‑sensing‑sensitivity.

Safety‑Operation‑Reminder

Keep hands away from moving rotary‑blade and reciprocating travel‑zone while equipment is running. Wear protective‑gloves during installation or replacement of sharp cutting‑blades. Confirm specimen is securely clamped before starting test‑cycle. Reliable equipment‑grounding must be completed before power‑on. Periodically inspect blade‑condition and penetration‑detection‑sensitivity.
