The invention discloses a T-shaped block processing technique. The technique comprises the steps of cutting a material with a laser cutter, so that a product is primarily formed according to the drawing size through cutting; positioning and machining the cut product with a miller, wherein a round hole with a diameter of 5+0.2 mm is formed in the position, 23.5 cm away from the bottom end and 20 mm from the side face, of the product; tapping M6 threads into the round hole; milling holes with the miller, wherein through holes with diameters of 4.2 mm are drilled in the two side faces of the bottom of the product, and the distance between the two through holes is 27+/-0.2 mm; chamfering the machined product to obtain an angle R2; 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 cutting through the laser cutter, milling and machining through the miller, tapping, chamfering, deburring, surface polishing and quality inspection, production requirements are met, the product is made to meet requirements, defective percentage is reduced, and production cost is reduced.
