Numerical control lathe machines the 6 big notes in the process

Dosage of logical choice cutting is machined to efficient metallic cutting for, be machined condition of tool of material, cutting, cutting is 3 gist element. These are deciding life of handling time, cutting tool and treatment quality. The treatment way with efficient economy is reasonable necessarily chose cutting condition. The 3 element of cutting condition: Cutting speed, feed and cut the loss that cites a cutting tool greatly directly. Accompany those who follow a cutting rate to rise, temperature of point of a knife can rise, can produce machine, chemical, wear away hotly. Cutting rate rises cutting tool life to be able to reduce 1/2. The relation wears away to arise inside dinky limits at the back of feed condition and cutting tool. But feed is big, cutting temperature rises, wear away from the back big. It is righter than cutting speed the impact of cutting tool is little. Cut be opposite greatly although the influence of cutting tool is big without cutting speed and feed, but be in tiny when cutting deep cutting, by layer of sclerosis of cutting material generation, same meeting affects the life of cutting tool. Sort of position of the material that the user wants a basis to be machined, hardness, cutting, material, feed, cut the cutting rate that waits for a choice greatly to use. The machines a condition make choice of that suits most is the make choice of on the foundation in these elements. Well-regulated, wear away steadily the condition that reaching life just is ideal. However, in real operation, the choice of cutting tool life and cutting tool wear away, be waited to concern by quantity of heat of noise of quality of treatment size variation, surface, cutting, treatment. When machining a condition certainly, need undertakes study according to actual condition. To the difficult treatment material such as stainless steel and heat-resisting alloy, can use refrigerant or choose the crucial point with good tigidity. 2.

When thick car of logical choice cutting tool, should pick strength the cutting tool with tall, good durability, so that satisfy the requirement of quantity of big back penetration of a cutting tool, big feed when thick car. When fine vehicle, should choose precision the cutting tool with tall, good durability, in order to assure the requirement of treatment precision. To decrease the time that change a knife is mixed convenient to the knife, answer to use machine clip knife and machine clip bit as far as possible. 3.

Logical choice clamping apparatus chooses general clamping apparatus to hold clip work as far as possible, avoid to use special fixture; Spare parts fixed position is standard coincide, in order to reduce fixed position error. 4.

Course of treatment of certain treatment course is in showing numerical control machine tool machines a process, cutting tool is mixed relative to the athletic contrail of the spare parts direction. Should assure to machine precision and surface coarse requirement; Should shorten as far as possible treatment course, reduce time of cutting tool idle stroke. 5.

The connection that machines course and mental allowance is current, had not achieved in numerical control lathe popularize use condition to fall, should get on semifinished product commonly overmuch surplus, the surplus arrangement that contains hard cortex of forge, casting especially is machined on common lathe. If must use numerical control lathe to add man-hour, need to notice the agile arrangement of the program. 6.

Point of clamping apparatus installation is current the join of hydraulic pressure chuck and oil cylinder of hydraulic pressure clamp relies on pull rod implementation. Point of clamp of hydraulic pressure chuck is as follows: Use the screw cap on oil cylinder of hydraulic pressure of the debus that move a hand above all, debus pulls a tube, take out from main shaft back end, reoccupy moves hand debus chuck to secure bolt, can debus chuck. What the Xiu Guangren on cutting tool points to is deputy at the back of cutting tool edge slant after horny way grinds a paragraph of small when go out as simultaneous as point of a knife where a thing can be put to best use to basically be used at edge cutting, undertake cutting is equivalent to place to go of finish machining process 2 times the bruise purpose such as burr.
