Cast Iron T Slot Base Plate

Cast Iron T  Slot Base Plate is an important tool in industrial production, especially widely used in mechanical processing, assembly, and inspection processes. Here is a detailed introduction:

Structure and Characteristics

Material: Usually made of high - quality cast iron, such as HT200, HT300. Cast iron has good wear - resistance, shock - absorption, and low thermal expansion coefficient, which can ensure the stability and accuracy of the base plate during use.

T - Slot Design: The surface of the plate is equipped with several parallel T - slots. The size and spacing of the T - slots comply with relevant standards. The common T - slot widths are 12mm, 14mm, 18mm, etc. The T - slots are used to install bolts, nuts, and various clamping fixtures, which can quickly and accurately position and clamp workpieces, improving work efficiency.

Flatness and Precision: The working surface of the Cast Iron T - Slot Base Plate has high flatness. The precision can be divided into different levels such as 00 - class, 0 - class, 1 - class, 2 - class, and 3 - class according to the national standard. The higher the precision level, the smaller the flatness error. For example, the flatness tolerance of the 00 - class base plate can reach within ±0.005mm/m, which provides a reliable guarantee for high - precision processing and measurement.

Applications

Machining: In the machining process, it is used as a workbench for machine tools. Workpieces are fixed on the base plate through T - slots, and then various machining operations such as milling, turning, and drilling are carried out. The high flatness and precision of the base plate can ensure the machining accuracy of workpieces.

Assembly: In the assembly workshop, it is used as an assembly platform. Different parts are assembled on the base plate according to the process requirements. The T - slots can be used to position and fix the fixtures, which helps to improve the assembly accuracy and efficiency.

Inspection: As a measurement reference platform, the Cast Iron T - Slot Base Plate is used to detect the dimensional accuracy, form accuracy, and position accuracy of workpieces. Measuring instruments such as dial indicators and height gauges are used in combination with the T - slots to complete the measurement work.

Maintenance and Use Precautions

Maintenance: Regularly clean the surface of the base plate to remove dirt, iron filings, and oil stains. Apply anti - rust oil regularly to prevent rust. Avoid placing heavy and sharp objects on the surface of the base plate to prevent scratches and damage to the surface.

Use Precautions: When using, the base plate should be placed on a stable foundation to ensure its levelness. When clamping workpieces, do not over - tighten the bolts to avoid deforming the base plate. After use, the base plate should be cleaned and maintained in a timely manner and stored in a dry and ventilated place.
