What Are Tissue Paper Cutting Machine Knives?
Tissue paper cutting machine knives are the blades fitted to tissue converting and packaging machines that cut handkerchief paper, facial tissue and napkin stock into logs and finished sheets. Because these lines run at very high speed, the knife edge must stay sharp, smooth and burr-free; a poor edge produces paper dust, ragged cuts and frequent stoppages.
Which Steel Grades Work Best?
For most tissue packaging machines we recommend SKD-11 (D2) cold work tool steel or high speed steel such as SKH-51/M2. Both grades respond well to vacuum heat treatment, reaching a Rockwell hardness of HRC 58–64, which gives the knife excellent wear resistance and a long service life in continuous operation. For special applications, alloy tool steels with coatings are also available.
Hardness, Edge Finish and Precision
Three details decide how a tissue paper cutting knife performs on your machine:
- Hardness: HRC 58–64 after vacuum heat treatment, balanced against toughness so the edge does not chip.
- Edge finish: a finely ground, burr-free edge gives clean cuts and less dust on the converting line.
- Precision: hole positions and dimensions must match the machine assembly drawing so the knife mounts without rework.
How to Choose the Right Knife for Your Machine
- Confirm your machine model — tissue converting lines such as W+D, Senning and other packaging machines each need a specific knife geometry.
- Send the old knife's drawing, sample, or at least outer diameter, thickness and hole layout.
- Match the steel to your product: printed or laminated tissue wears edges faster and justifies a higher alloy grade.
- Ask about hardness testing and 100% edge inspection before shipment.
OEM Production from ZHONGJIAN TECH
ZHONGJIAN TECH is a factory-direct manufacturer of industrial machine knives and cutting blades. We produce tissue paper cutting machine knives to customer drawings and samples, recommend the right steel for your product and line speed, and control heat treatment and grinding in our own workshop. Whether you need a trial batch or a standing monthly order, our OEM program keeps sizes consistent order after order.
Care and Replacement Tips
Keep a spare set of knives mounted and ready, log cutting meters per edge, and regrind before the edge visibly dulls. Never let a dull knife tear the tissue — dust and heat build-up shorten the life of the machine's cutting unit as well.
