The invention discloses an L-shaped block processing technique. The technique comprises the steps of machining a material with a lathe, so that a product is primarily formed into an L shape according to the drawing size through cutting, wherein the thickness of the L-shaped block is 10 mm; machining the cut product with a miller, wherein round holes with diameters of 7+/-0.1 mm are milled in the sides of the L shape; tapping M8 threads into the round holes with a tapping machine; chamfering the 58.4 mm high side of the L shape to obtain eight angles of 45 degrees; milling the 60 mm long side of the L shape with the miller; deburring the machined product and conducting surface polishing to enable the surface roughness to reach Ra3.2; inspecting and storing the product. According to the technique, by means of turning through the lathe, milling and machining through the miller, tapping with the tapping machine, chamfering, deburring, surface polishing and quality inspection, production requirements are met, the precision and strength of the produced L-shaped block are improved, the L-shaped block is made to meet requirements, defective percentage is reduced, and production cost is reduced.
