Lathe work saves the 3 respects brief introduction of material in exercitation process

Lathe work exercitation is the mastery of a skill or technique that education student uses lathe of lathe work craft and operation, achieve the important segment that sets technical grade standard. In process of lathe work exercitation need uses much material, cutting tool and phyletic and various measure. Of material using up the loss with cutting tool is quite big, the measure with a lot of high prices also has the need of the ability in machining a process in specific work only. Be aimed at this kind of circumstance, very the exercitation funds defray that is necessary to explore a few efficient ways to reduce the school. The author summarizes result of education of exercitation of old lathe work, the savable in process of exercitation of labour of Baconian dispatch a vehicle 3 respects. Show cent to narrate following: ? Mu Xi of 〔 of arc ⒔ banter pours な enlighten Ang  denounces instrument Mou Mu to show banter enlighten boil  to the gate of a lane Shan of shellfish of the lament that surname cangue seeks army? and material has quite large economic space, because this is economic material is very important. Below in order to 3 kinds of methods can make material is used up 50% above are reduced on original basis. 1.

Task conformity has a lot of content to compare simple task in lathe work exercitation, if part these tasks exercitation certainly will causes older stuff to use up, can become these task conformity the measure accordingly the task with less, not great difficulty has a field trip. For instance, are there such 3 tasks: commonly on teaching material? The instruct Xiang dark blue of all of Jing of honest storehouse  of ⒊ of Jin of  of low Xiang storehouse sees? can become conformity of the taper seat outside face of the cylinder outside the car and car axle kind workpiece; mixes face of the cylinder inside the car conformity of the taper seat inside the car. Will original conformity of 3 simple tasks becomes the task with two not great difficulty. 2.

Material continuance data continues even if will before the exercitation finished product of add task continues, regard the exercitation of follow-up task as preform. For instance, the axis kind the exercitation finished product of workpiece serves as cover kind of workpiece the exercitation preform of workpiece of the whorl outside mixing, serve as the exercitation finished product that covers kind of work inside the exercitation preform of whorl workpiece. 3.

Reduce dimension to be below the premise that does not affect student exercitation result, the dimension appropriate of exercitation workpiece is small should not be big. 3 kinds of methods are reducing above while material is used up, the electric energy of the loss that also reduced cutting tool and lathe is used up. 2, lathe tool of gold of economic cutting tool, the loss place of this kind of lathe tool basically is knife head most, and the loss of arbor is dinky. Accordingly, be aimed at this kind of circumstance, also be a of economic cutting tool important way to discarding arbor undertakes recycle, particular way has two kinds as follows: 1.

Abstain lathe tool to buy knife head, the form that buys knife head by place on deserted arbor and dimension give knife slot in the mill on milling machine, it is solder of knife head drill rod next inside knife chamfer, made solder type hard alloy lathe tool. 50% of the price inadequacy of head of a knife is whole lathe tool, using this kind of method to save the effect of cutting tool is quite apparent. 2.

Simulation training wears integral type in exercise blade when common figuration lathe tool, when edge appearance controls; harder to grind echelon whorl lathe tool and worm lathe tool in exercise blade, cutting tool angle assures harder. This kind of task can use deserted arbor to replace the high speed steel bar with high price to let student imitate train, after waiting for a student to train adroitness, let them practice blade grinding with high speed steel bar again. Such, can avoid high speed steel bar to rub the needless wear and tear in training a process in blade. 3, economic measuring tool the measure with very low to a few use frequency, high price, if lathe amount is configured, be like a basis is unwise, wasteful, very the sort that is necessary to control this kind of measure and amount. Specific be like: of below 3 kinds of practices? ?1.

Abstain measure to use existing exercitation equipment to make the measuring tool with simple structure, replace those use frequency the measure with low, structure is complex and relevant high price. For instance, internal diameter dial gauge should be used when the car covers kind of work, this kind of measure is measuring find sth useful of the ability when the deep aperture with precision higher demand only, and structure complex, use trouble, price is more expensive. Actually, it is OK to affecting the situation that measures precision to fall replace with plug guage, and plug guage structure is simple, it is easy to make, can abstain on existing lathe, cost is very low. 2.

Changeover measurement technique is not affecting the premise that measures precision to fall, undertake metrical with those low-cost commonly used measure. For instance, when measuring echelon screw center diameter, use single shot to measure as far as possible and do not use 3 needles to measure; when measuring worm transverse tooth thickness, can use single shot indirect measurement replaces vernier calipers of use transverse tooth thickness (gear callipers) measure what undertake directly. Can avoid to use the price so very tall, use frequency micrometer of very low public law line and vernier calipers of transverse tooth thickness, and use value is relative the outside callipers with cheap, use very tall frequency. Very costly, use frequency very low gauge block; machines big eccentric throw on lathe (when the prejudicial workpiece of eccentric throw E>5mm) , undertake searching to workpiece measure is gauge block and dial gauge commonly, and among them gauge block can be used procrastinate in lathe board dial will replace. Carry out a proof, below the premise that does not reduce education effect, economic data, cutting tool and measure can reduce the education cost that lathe work jackarooes greatly, achieve the result of managing education funds finally.
