Knives Sharpness Testing Equipment


Knives Sharpness Testing Equipment is mounted in a position with the edge vertical and a pack of specially developed synthetic paper (Not included) is lowered on to knives sharpness tester. The clamping fixture with the blade move back and forth the blade cuts into the paper, the depth of the cut being the measurement of sharpness.

- ICP (Initial Cutting Performance) representing the cutting ability (sharpness) of the blade as supplied

- CC (Total Card Cut) cutting edge retention) which represents the life of the blade by giving a measure of its total cutting ability  

1.Ball screw with servo motor to ensure high accuracy of movement
2.Linear optical scale, Laser displacement detector
3. PLC programmable controller, LCD touch screen interface, easy to operate 
4.Automatic add paper during test 
5.With USB interface to output test results 
6.Display test results and graph 
7.Two test items: Initial Cutting Performance (ICP) and Total Card Cut (TCC)

The Main Technical Parameter:

1) The reciprocating table with fixture to clamp the blade,  

     the movement was driven by ball screw and servo motor.

2) Cutting stroke is settable from 20 to 60 mm.

    (standard requirement is 40 mm)

3) Travel speed is adjustable from 20 to 80 mm per second.

    (Standard requirement is 50  mm/second)

4) 4 digits pre-set counter for test cycles setting.

5) Linear optical scale to detect each cutting depth of each single stroke

    ( forward and backward)

6) The tester use PLC (programmable logic controller) and large touch screen monitor for


7) The cut depth was automatically recorded and accumulated, Total amount will be    

    displayed after finish the test cycles.


The knife is fixed in the machine and the blade is mounted in a position with the edge vertical. The blade is moved back and forth whilst a pack of special testing paper is lowered onto the blade. The blade cuts through the paper and the sharpness is then measured. 

The need for such a cutting performance test is internationally agreed:
• to compare objectively various knife blades and determine which one is superior to another.
• to monitor the consistency of quality of cutting performance against the norm of manufacturing to be sure that the knives are within the standard values agreed upon.
• to be used as a development tool to enable research into the optimum steel, heat treatment, surface coating, edge geometry and finishing operations to suit the application.
The machine system answers the questions " How sharp is it?" and " How long will the sharpness last?"
