DRK114 Adjustable Standard Paper Cutting Knife

Overview

The DRK114 Adjustable Standard Paper Cutting Knife is a precision-engineered manual cutting instrument designed for consistent, repeatable specimen preparation in quality control laboratories and R&D facilities. Based on the fundamental principle of controlled shear cutting under defined blade geometry and applied force, the DRK114 conforms to internationally recognized standards for paper and board sampling—including ISO 186, ISO 1924-1, TAPPI T403, and GB/T 450—ensuring dimensional accuracy and edge integrity critical for tensile, burst, tear, and folding endurance testing. Its rigid cast-aluminum frame, hardened stainless-steel blade carrier, and micrometer-adjustable stop mechanism enable reproducible cut widths from 15 mm to 300 mm with ±0.2 mm positional tolerance. Unlike generic utility knives or non-calibrated guillotines, the DRK114 integrates mechanical registration features that eliminate operator-induced variability during sample cropping.

Key Features

• Adjustable cutting width range: 15–300 mm, calibrated via integrated vernier scale and locking micrometer stop
• Replaceable high-carbon steel cutting blade (HRC 58–62), pre-aligned and tensioned for uniform shear force distribution
• Stainless-steel anvil surface with engraved reference grid (10 mm pitch) and zero-reference mark for rapid alignment
• Ergonomic dual-hand lever system with progressive resistance curve, minimizing hand fatigue during high-volume sample prep
• Integrated specimen retention clamp with spring-loaded pressure plate (adjustable 0.5–3.0 N load) to prevent slippage during cutting
• Modular base design compatible with standard laboratory workbenches; optional vacuum-mount adapter available for vibration-sensitive environments

Sample Compatibility & Compliance

The DRK114 accommodates sheet materials up to 1.2 mm thickness and 400 mm maximum width, including uncoated and coated papers, corrugated board liners, kraft packaging substrates, nonwovens, thin foils, and laminated composites. All structural components comply with ISO 9001:2015 manufacturing controls, and dimensional tolerances adhere to ISO/IEC 17025 calibration traceability requirements when used with certified gauge blocks. The device supports GLP-compliant workflows through documented operator qualification records and routine performance verification per ASTM D882 Annex A3. Blade wear monitoring protocols are included in the user manual to maintain cutting edge consistency across ≥5,000 cuts per blade (typical service life under standard test conditions).

Software & Data Management

As a manually operated mechanical instrument, the DRK114 does not incorporate embedded electronics or firmware. However, it is fully compatible with LIMS and ELN platforms via standardized SOP documentation templates provided in PDF and editable Word formats. Each unit ships with a Certificate of Conformance (CoC) referencing ISO/IEC 17025-accredited dimensional verification data. Optional digital caliper integration kits (e.g., Mitutoyo Digimatic output) allow direct transfer of cut-width settings into laboratory information systems for audit trail generation. All documentation—including maintenance logs, blade replacement records, and periodic verification reports—meets FDA 21 CFR Part 11 requirements when implemented within validated electronic record environments.

Applications

• Preparation of standardized test specimens for tensile strength (ISO 1924-2, TAPPI T494), burst resistance (ISO 2758), and tear propagation (ISO 1974)
• Cutting of multi-layer packaging composites prior to peel adhesion or seal integrity evaluation
• Dimensional conditioning of fiberboard samples for edge crush test (ECT) and flat crush test (FCT) per ASTM D6342 and ISO 3037
• Specimen cropping in pulp and paper mills for routine QC against ISO 186 sampling plans
• Academic research labs requiring traceable, low-variability sample geometry for structure–property correlation studies

FAQ

What standards does the DRK114 comply with for paper cutting accuracy?
It meets dimensional and functional requirements specified in ISO 186, ISO 1924-1, TAPPI T403, and GB/T 450 for laboratory sample preparation.
Is blade replacement tool-free?
Yes—the blade retention screw uses a hex-key interface supplied with the unit; full replacement takes <60 seconds without disassembly of the carrier assembly.
Can the DRK114 be used for non-paper substrates such as thin plastic films?
Yes, provided material thickness ≤1.2 mm and tensile modulus ≥100 MPa; users must verify edge quality microscopically before deploying for mechanical testing.
Does Drick provide calibration services outside China?
Yes—certified calibration support is available through authorized service partners in the US (IL), Germany (DE), and Singapore (SG), with turnaround times of 5–7 business days.
Is operator training included with purchase?
Yes—Drick offers remote video-based SOP training and on-site technician-led sessions (travel fees apply outside mainland China).
