Steel mold to provide a uniform distribution of the allowance for each tool ensures a constant and high productivity and safety of the cutting process. When ap / ae (axial depth of cut / radial depth of cut) unchanged, cutting speed and feed rate can be kept constant at a high level. Thus, the mechanical action and workload on the cutting edge of change is small, so the heat generated and less fatigue, thereby increasing tool life. If the subsequent step is a step of semi-finishing, in particular for all the finishing process, or part of the processing can be carried out no no processing. Constant material allowance is the basic standard high-speed cutting applications. Use coal stove, oil furnace, gas stove, are likely to make the box-type furnace heating workpiece when the workpiece oxygen decarbonization SKH-9, must take measures to prevent increases heart. In the well-equipped, the best way is to pass into the protective gas, but in the majority of small and medium enterprises, the current can still do so. It describes several simple way, when conditions permit adoption. SKH-9 high-speed steel in the domestic ore market in Hebei iron ore fines prices weak stability operation, part of the large mines to cut prices, market pessimism spread. Imported ore prices rose and then fell, 62% grade Platts iron ore index in the October 23 closing price of $ 79.75 per ton, down $ 1.25 a week. After the National Day holiday, steel replenishment demand rises, iron ore port stocks declined. But SKH-9 manufacturers, such replenishment needs unspeakable "big bang" SKH-9 rod, steel procurement are still very cautious, both supply and demand is still in a state of stalemate. S136H is pre hard, but the hardness is not very high, at around HRC30 degrees, do not require heat treatment, S136 steel is hardened material, very soft, need to be used after quenching, after quenching hardness can reach HRC58 degrees. The former requirement ratio for small quantities of injection mold, which is used in large quantities. So usually happen in large quantities, can be ordered S136 steel, different on these two areas, there is a demand of the customer can be the difference between these two areas, which were combined amount of the purchase, both to save costs, but also conducive reasonable to buy more high-quality steel! Metal heat treatment requirements for material handling must also have a clear enough understanding. Know the composition of features, performance characteristics, scope critical point, the physical and chemical parameters or characteristics of the material of various materials (here including thermal properties, swelling properties and phase transition has occurred and other information). Domestic part have an influence in the local medium-sized steel mills have begun overhaul before and after National Day, which also makes the availability of resources in some areas to reduce the appearance of tight supply of steel products, while taking into account the ongoing maintenance of large-scale steel mills have not yet formed the size of the domestic steel supply and demand pattern overall temporarily unable to change, but in steel prices continued to fall and winter coming, the total domestic steel production is the line into a slow decline. Also, another concern news is that a substantial increase in China's steel exports this year, the domestic supply and demand pressures eased to some extent, but the Government has recently said that next year China's steel export tax rebate policy will be canceled when the steel export growth is expected to occur changes in steel prices will increase the uncertainty of the market outlook.
