The milling machine spare part in question is the HT03-20 milling bits holder, designed for the W1900, W2000, and W2100 milling machines. The spare part has the reference number 198001. Here is a 500-word English description with key terms:

The HT03-20 milling bits holder is a critical spare part used in milling machines, specifically designed for the W1900, W2000, and W2100 models. With the reference number 198001, this holder plays a vital role in the efficient milling of asphalt surfaces during road construction projects.

The primary function of the HT03-20 milling bits holder is to securely hold and position the milling bits on the milling drum of the machine. The milling bits, also known as cutting tools or teeth, are responsible for removing the surface layer of the asphalt pavement, allowing for smooth and precise milling operations.

Designed specifically for the W1900, W2000, and W2100 milling machines, the HT03-20 holder is engineered to meet the machines' unique requirements. It is designed to withstand the demanding conditions encountered in road construction, including high-speed milling, heavy loads, and repetitive impacts.

The holder is typically constructed from high-strength materials such as hardened steel or alloy, ensuring its ability to withstand the forces and stresses involved in milling operations. These materials provide durability and longevity, ensuring the holder's reliable performance over extended periods.

Replacement of the HT03-20 milling bits holder is necessary when the existing holder becomes worn, damaged, or reaches the end of its service life. Timely replacement ensures optimal milling performance and minimizes downtime during road construction projects.

The installation of the HT03-20 holder involves removing the worn or damaged holder and securely attaching the new holder to the milling drum of the machine. Proper alignment and adjustment of the holder are crucial to ensure the accurate positioning and stability of the milling bits during milling operations.

Regular maintenance and inspection of the HT03-20 milling bits holder are essential to ensure its continued performance and reliability. Inspection for wear, damage, or signs of fatigue is necessary, and timely replacement of the holder is recommended to prevent any adverse effects on milling operations.

The HT03-20 milling bits holder with the reference number 198001 is a critical spare part for the W1900, W2000, and W2100 milling machines. It securely holds and positions the milling bits, enabling efficient and precise milling of asphalt surfaces. Constructed from durable materials and designed for optimal functionality, the holder withstands the rigors of road construction and contributes to the overall efficiency and effectiveness of the milling machines.
