263-7082 Base Holder for Milling Machine PM200

Product Introduction

The base holder on the milling drum of a milling machine is a core load-bearing component. Its main function is to provide a stable installation foundation and accurate positioning for the tool holder, while transmitting the rotational power of the milling drum. During operation, the three form a close connection: the base holder locks the tool holder through a fixed structure to prevent it from shifting during high-speed cutting; the tool holder, as an intermediate connecting part, firmly fixes the pick and transmits the power from the base holder to the pick. In addition, the base holder can buffer cutting impacts, reduce vibration damage to the tool holder and pick, and extend their service life. The three cooperate with each other to ensure the pick obtains stable cutting force and accurately completes road milling operations, making them a key structural combination to guarantee operation efficiency and quality. 

How to determine the wear level of the milling machine tool holder?

To judge the wear degree of the milling machine's tool holder, you can adopt the following methods. First, conduct a visual inspection: check if there are obvious scratches, deformations, cracks or excessive wear marks on the tool holder's surface, especially at the positions where it connects with the base holder and the pick. Second, perform dimensional measurement: compare the tool holder's key dimensions (such as the fixing hole diameter and installation thickness) with the standard specifications using simple measuring tools; significant deviations indicate severe wear. Third, observe operational performance: if there are abnormal vibrations, noises during milling, or the pick loosens easily, or the milling quality declines, these may be signs of excessive wear of the tool holder. Once obvious wear symptoms are found, replace the tool holder in time to avoid operational risks.

How to choose the right milling machine base holder?

To choose the right milling machine base holder, you need to consider several key factors. Firstly, ensure compatibility: it must match the model of the milling drum and tool holder. Incorrect specifications will lead to installation problems and even affect the stability of the entire cutting system. Secondly, select appropriate materials: for high-intensity operations or hard road surfaces (like concrete), choose wear-resistant and impact-resistant materials to withstand strong cutting forces and vibrations. Thirdly, focus on structural design: prioritize products with stable fixing structures to prevent the tool holder from shifting during operation, and prefer standardized designs for easy installation and maintenance. Fourthly, consider working conditions: adjust your choice according to milling depth, speed and the content of hard impurities on the road. Finally, opt for products from reliable brands to guarantee quality and long-term stable performance, reducing subsequent maintenance costs.
