SN-MCXE Inclined Surface COF Tester

The SN-MCXE Inclined Surface COF Tester is based on the inclined-plane sliding method: the specimen is laid flat on the platform with the slider, and the inclined plane is slowly raised. When the slider just starts to slide, the critical angle θ is recorded, and the static coefficient of friction is automatically calculated as μ = tan θ. The inclined plane features a 0–85° range, 0.01° resolution, adjustable angular speed, and automatic reset, accurately capturing the instant of sliding. It is used to evaluate the slip properties of paper, films, conveyor belts, etc.

Product Introduction

Standards

ASTM D202, ASTM D4918, TAPPI T815

Application Fields

Intended Use

Professionally used to measure the static coefficient of friction of paper, plastic films, sheets, conveyor belts and other materials for evaluating surface slip property. It helps control and adjust process parameters such as bag opening performance and packaging machine operating speed, ensuring smooth material conveying and packaging on high-speed production lines.

Operating Principle

It adopts the classic inclined plane sliding method. During the test, the specimen is mounted on the slider and laid flat on the test platform. The instrument elevates the inclined plane slowly in automatic or manual mode. Record the critical angle θ the moment the slider starts to slide. The static coefficient of friction (μS) is automatically calculated by the formula: μ = tanθ.

Product Features

High-precision measurement: Adopts high-precision angle sensor with angle resolution up to 0.01°, test angle range: 0° ~ 85°.
Intelligent control: Microcomputer controlled system with LCD touch screen and menu operation interface. Supports stepless adjustment of angular velocity and automatic reset of test platform.
Anti-interference design: Both test platform and slider are demagnetized and tested for residual magnetism, effectively reducing systematic test error and ensuring reliable test results.
Convenient data management: Equipped with built-in mini printer and standard RS232 interface, supporting direct report printing or connection to PC for data transmission and centralized management.
