Corundum grinding wheel through hole

Common types of flat wheel wheels Code: P main purposes: cylindrical grinding, internal grinding, flat grinding, centerless grinding, thread grinding, and free two-bevel grinding wheel Code: PSX main purposes: grinding gear tooth surface, single thread grinding at the round and by single-bevel face grinding wheel Code: PDX main purposes: grinding various jagged, grinding mills, reamers, shaper cutters and other single convex wheel Code: PDT main purposes: mainly to solve the large-diameter , difficult to manufacture thin wheel, use the same single-sided concave grinding wheel flat grinding wheel Code: PDA main purposes: for internal grinding and surface grinding, a larger outer diameter for cylindrical grinding wheel biconcave code: PSA main purposes: for cylindrical grinding, sharpening tools, but also for centerless grinding wheel and guide wheel barrel wheel Code: N Main purposes: for vertical surface grinding cup wheels Code: B main purposes: Sharpening cutters, reamers, reamers, broaches, cutter, etc., can also be used for flat and circular grinding wheel bowl Code: BW main purposes: grinding mills, reamers, broaches, disc-shaped tools , shaper cutters, reamers, etc., it can also be used for disc wheel grinding machines, rails, etc. Code: D purposes: for grinding mills, reamers, broaches, shaper cutters and other tools, generally used for large size gear grinding surface material A, WA, PA, MA, SA, GC, C, ZA, SG abrasive corundum WA type selection is harder than corundum, abrasive easily broken, sharp edges and corners, cutting, small grinding heat and so on. Suitable for hard materials, heat sensitive strong grinding steel. Such as hardened steel. High carbon steel, general high-speed steel, alloy steel grinding. Mainly used tools, cutting tools, dies, gears, thread, thin-walled parts such as grinding and profile grinding. Corundum A high hardness, toughness, suitable for high tensile strength metallic materials grinding, such as general carbon steel, alloy steel, malleable iron and hard bronze. Green silicon carbide GC high hardness, brittleness, abrasive sharp, good thermal conductivity. Suitable for carbide cutting tools, parts and non-ferrous metals, non-metallic grinding. Black silicon carbide C high hardness, brittle, abrasive sharp, has a thermal conductivity. Suitable for non-ferrous metals and non-metallic materials grinding. PA chromium corundum and corundum hardness similar toughness is higher than corundum, abrasive cutting edge sharp edges to maintain good, high durability. Suitable for hardened steel, alloy steel grinding tool and the workpiece, as well as measuring and instrument parts and other precision grinding, also suitable for molding grinding. Wheel safe use 1. Before starting the machine, check the machine guards and the various actions of the reset switch is adjusted in place and firmly. 2, the use of shields should be covering at least half the wheel diameter. 3, wheel mounted on the grinding machine spindle, you must be idle, idle time is less than 5 minutes. 4, the end face of the grinding wheel is not used exclusively work, prohibited the use of end face grinding wheel. 5, during grinding, prohibit the use of lever pressing the workpiece to increase the pressure on the wheel. 6, when machining or grinding wheel dressing, eating knife should be appropriate and the use of specialized dressing wheel dressing tools. 7, before the wheel stops turning the coolant closed, to avoid affecting wheel balance performance. 8, prohibit the use of abrasive binders destructive grinding fluid.
