selection techniques for commonly used machine clamp indexable turning knife blades


&nbsp& nbsp& nbsp& nbsp; the selection principle of the blade for the outer circle of the car is mainly determined based on the specific situation of the processing technology. generally, it is necessary to choose blades with higher versatility and more cutting edges on the same blade. when rough turning, choose a larger size, and when fine or semi fine turning, choose a smaller size. s-shaped: with four cutting edges, the cutting edge is shorter (referring to the same inner circle diameter), and the blade tip has higher strength. it is mainly used for 75 ° c 45° turning tool, used in inner hole cutting to process through holes. t-shaped: with three cutting edges, the cutting edge is longer and the blade tip strength is low. when used on ordinary lathes, blades with a pair of offset angles are often used to improve the blade tip strength. mainly used for 90° turning tool. the inner hole turning tool is mainly used for processing blind holes and step holes< br/>
&nbsp< br/>


&nbsp& nbsp; c-shaped: there are two types of sharp edges. 100° the two sharp edges of the blade have high strength and are generally made into 75 degrees; turning tool, used for rough turning of outer circles and end faces, 80° the two cutting edges of the sharp angle of the tool have high strength, and can be used to process the end face or cylindrical surface without changing the tool. it is generally used in inner hole turning tools to process step holes. r-shaped: circular blade edge, used for processing special curved surfaces, with high blade utilization but large radial force. w-shaped: three short edges with a sharp angle of 80 degrees; the tool tip has high strength and is mainly used for machining cylindrical and stepped surfaces on ordinary lathes< br/>


&nbsp& nbsp& nbsp; d-shaped: two long edges with a sharp angle of 55 degrees; the blade tip has low strength and is mainly used for contour machining, when made into 93° the cutting angle during turning should not exceed 27 degrees 30°; made into 62.5° when turning the tool, the cutting angle should not exceed 57 degrees 60°, it can be used for step holes and shallow root cleaning when machining inner holes< br/>


&nbsp& nbsp; v-shaped: with two long edges and a sharp angle of 35 degrees; the blade tip has low strength and is used for contour machining. make 93° when turning the tool, the cutting angle should not exceed 50 degrees;; make 72.5° when turning the tool, the cutting angle should not exceed 70 degrees;; made into 107.5° the cutting angle during turning should not exceed 35 degrees;. figure 1, figure 2, ordinary q-shaped blade, figure 3, cutting blade with chip groove, figure 4, figure 5, figure 6, figure 7, figure 8, figure 9, figure 10, cutting and groove cutting blade: cutting blade: commonly used on ordinary lathes is a q-shaped blade, which can be re ground and is generally priced 2-3 yuan/piece lower than an adjustable turning tool blade. its disadvantage is that the blade edge is straight, which cannot cause transverse shrinkage deformation of chips and is prone to friction with the machined surface, in addition, its side deviation angle and back angle are very small, so the cutting heat is high and it is easy to wear. when using it, it is necessary to observe the condition of the cutting edge at all times and timely regrind or
