Description: Also known as a T-slot workbench, it is a type of industrial measuring tool used primarily for fixing workpieces. It serves as a fundamental working platform for mechanics to adjust, assemble, and repair equipment. TAG: Aluminum inspection flat, cast iron splicing flat, floor-mounted boring machine worktable. The T-slot flat, also known as a T-slot worktable, is a type of industrial measuring tool used primarily for fixing workpieces. It serves as a basic working platform for fitters to adjust, assemble, and repair equipment. The surface hardness of high-strength cast iron HT200-300 is HB170-240; after two types of manual treatment (manual annealing at 600-700 degrees and natural aging over 2-3 years), this material offers stable precision and excellent wear resistance. Some defects can occur in T-slot plates during the production process, but these can be corrected through appropriate manufacturing methods. The main defects of such plates include pores, sand holes, inclusion of sand, and shrinkage porosity. The defects in cast iron plates are subject to detailed regulations in the \"Mechanical Industry Standards of the People’s Republic of China\" JB/T 7974—2000. The service life of these plates is closely related to the repair of their defects; therefore, when repairing such defects, it is necessary to follow the specified procedures strictly. Production process flow for T-slot flat plates: 1. Rough blank: Prepare drawings according to technical requirements, create wooden molds based on those drawings, select materials, shape the blank, dry it, cast it, remove the sand from it, clean it, and inspect various parts of the rough blank. 2. Machining: Visual inspection and marking, machining, and inspection. 3. Leveling of the workpiece, manual scraping and lapping, and inspection by the quality control department. 4. Surface treatment, painting, packaging, and storage.
