Krauss friction testing machine

1. Description

YXF-D Brake friction material drag testing machine (Krauss machine) is designed and manufactured for quality control of friction material. It can measure the friction value, verify temperature behavior and determine the wear.

This machine includes control console, 75kW AC drive motor, servo brake pressure system, cooling system, dedusting system and computer with software control system.

2. Application

Full size disc brake pads

Full size drum brake lining

Industrial friction material for lift

Friction material for rail blocks etc.

3. Features

l The machine is integrated with control console. Saving space.

l The software provide fully automatic unattended operation.The operator can select test parameters, test cycles, cycle interval,display data, monitor test functions and execute desired test sequences.
