Product Overview
In high-speed shot blasting operations, the top guard plate serves not only as the first line of wear resistance but also as the key to maintaining the airtightness of the shot blasting chamber. This machine-processed top guard plate departs from the traditional practice of directly using castings as raw materials. Instead, it undergoes a full CNC (Computer Numerical Control) precision milling process to reprocess the installation contact surfaces and positioning holes. It completely resolves the common problems of surface unevenness, installation irregularity, and bolt hole deviation in ordinary cast guard plates, making it an ideal choice for the protection of high-end shot blasting machine housings.
Core Selling Points and Technical Specifications
CNC Precision Machining: The sealing surfaces of each guard plate are precisely machined by CNC, with a flatness control within 0.05 millimeters. This ensures a "mirror-like" fit with the shot blasting machine housing, effectively preventing shell erosion caused by fine steel balls.
High-Chromium Alloy Material: Special high-quality high-chromium wear-resistant cast iron (Cr18-Cr26) is selected, combined with advanced heat treatment processes, with a hardness stable at HRC60-65 degrees. It not only resists wear but also has excellent impact toughness.
Silent and Shock Absorption: Due to the tight installation and seamless gaps, resonance noise caused by loose components is eliminated. In high-speed operation environments, it significantly improves the running stability of the shot blasting machine and reduces equipment noise by 10-15%.
Precise Installation Hole Positioning: Using CNC positioning drilling, the bolt hole positions are ensured to be exactly the same as those of the original equipment, eliminating the need for repeated grinding during installation, and truly achieving "open box installation".
