Adjustable shims are a type of machine tool accessory, and they are generally indispensable for the installation of machine tool equipment, commonly used as machine tool feet. They offer some advantages such as low cost, high load-bearing capacity, wide adjustable range, and ease of use, making them highly popular in the market.
The function of adjusting washers:
Adjustable shims serve the purpose of adjustment and support. The vibration-damping rubber reduces the machine's vibration, minimizes the transmission of vibration forces, and prevents the entry of vibration forces, ensuring dimensional accuracy and quality. It controls the propagation of vibration and noise in the building structure's resonance. It allows for the assembly of rough and fine machining machines into production units, adapting to the development of logistics technology. The installation of machine tools does not require setting anchor bolts to the ground, providing good vibration reduction and appropriate verticality, making it possible to install on the floor above. The machine tool level can be adjusted, with a wide range, convenience, and ease. It uses nitrile synthetic rubber, which is resistant to oils and coolants.
Adjustments to the material of the shims can generally be divided into three types: forging, casting, and steel plate processing. Among them, forging has a rough surface and poor flatness, but due to its forged parts The processing technology involves striking the iron pads with a pneumatic hammer during the manufacturing process, which increases their density. This enhances their strength, making them highly suitable for the installation and adjustment of heavy-duty equipment.
Optimize the structural advantages of the shim.
The structure of the adjusting washer is simple, with stable performance, easy adjustment, and high bearing capacity, making it widely used. Installing machine tools with adjusting washers does not require setting anchor bolts to the ground, saving installation costs and shortening the installation period. Machine tool positions can be easily adjusted according to production needs, eliminating additional installation costs. To use, simply place the adjusting washer underneath the equipment and then adjust the height of the washer as required. The adjustable height is typically:3-15mmWhen using shims, adjust the machine tool level again after two weeks. It can improve the machining accuracy of the machine tool and has the functions of vibration resistance and noise reduction. Another use of adjusting shims is to align cast iron plates. The foundation plane where the shims are installed can be made of concrete or wood, requiring it to be flat and sturdy. To adjust, place the shims at the bottom of the plate, and then place a level on the working surface of the plate. If heavier workpieces are placed on the plate, it is important to frequently check for any deviation in the flatness of the plate. When selecting shims, we still need to choose the appropriate shims based on the weight of the equipment to avoid causing... Waste.
Adjusting the usage of shims:
1Adjustable washers are generally used in pairs, with a flat washer placed first on the concrete foundation that has been properly prepared.
2Place two wedge-shaped shims crosswise on top of the flat shim. Adjust by striking both shims with a hammer to utilize the angle of the shims to elevate or lower the equipment to achieve the desired level adjustment.
3Once the level is adjusted, then weld the adjusting pads to the bottom of the equipment base to secure them firmly.
4Cemented for optimal horizontal positioning during operation, reducing machine wear and tear. Cost of replacing equipment parts.
