Hunting machine tool is optimal investment redound plan

In the main product that finite liability company produces machine of coal Beijing colliery at present has large colliery to adopt timbering device with modern put together -- hydraulic pressure bracket, product application is in the whole nation and abroad a few large collieries. The demand that uses to hydraulic pressure bracket as domestic and international user is higher and higher, bracket is sided with gradually large change, high end changes development, the security of requirement bracket, dependability that handles automation degree, product want to have than before rise apparently. The machine tool device that my company uses is bed of main be open to traffic having general, vertical drilling machine, radial drilling machine, common milling machine of cylindrical grinder, common vertical, horizontal milling machine, boring machine, numerical control is double-faced lathe of milling machine, numerical control, numerical control is close boring machine of aperture drilling machine, deep aperture, deep aperture. The utilization rate of the machine tool is counted according to the equipment platform of some hour actuate / equipment total platform counts × 100% it is about 85% . Disinvestment cost needs to make an appointment with 4 ～ 6 years (cut a machine tool by gold) . Hydraulic pressure bracket basically is divided from the structure for structural member and hydraulic pressure component two kinds big, hydraulic pressure component includes hydraulic pressure again crock and all sorts of a powerful person kind, pipeline accessory. Cent of hydraulic pressure crock is mixed for double telescoping mast and odd telescoping mast all sorts of jack, among them the Kong Hezhong inside all sorts of earthen pipe is crock, vivid the circle outside lever of column, piston and Bao Bi direct covered treatment has difficulty each. The aperture inside earthen pipe belongs to deep Kong Jia to be versed in, exterior surface roughness and dimension precision demand are very high, and in the exterior surface roughness of the circle outside lever of crock, vivid column, piston and dimension precision ask likewise very tall; Bao Bi is oriented set not only the aperture inside the requirement and outside coaxial is spent between the circle have higher demand, because be thin wall structure, incidental be out of shape. ? Spend the effort with company technology old personnel, already? Solved afore-mentioned problems through using reasonable equipment, tool and sound technology. In finite liability company is investing machinery of coal Beijing colliery when buying a machine tool, the function that what consider above all is a machine tool whether requirement of the precision that satisfies a treatment spare parts, efficiency, the convenient sex of the dependability that considers a machine tool even, stability and maintenance, consider the price of the machine tool next, that is to say, below the premise of function of contented machine tool, through much square survey, seek the machine tool with relatively inferior value again. For rigid to production business, the function of the machine tool and dependability are crucial. Just think, if consider the price of the machine tool only cheap, when machining a spare parts, machine tool? Often appear breakdown, so the quality of the spare parts and time limit for a project cannot assure, affected the date of delivery of the product finally, lost credit, order goods again later it is very difficult to be met, of last company lived to become an issue. How to produce the biggest effect of the machine tool, shorten further is the investment redound of the equipment such as the machine tool periodic? My company took following step in producing practice: From the fountainhead of the spare parts, semifinished product begins, control surplus, semifinished product uses forging, cast as far as possible, use accurate forging, accurate cast even, reduce mental allowance as far as possible, need not machine to not important surface, can reduce the holding time of the machine tool so, reduce machine tool loss and cutting tool loss, reduce spare parts finished cost. Thick, finish machining is apart. The user is taller and taller to the requirement of the product now, wait besides the quality to the product, function outside having higher demand, still ask to produce an enterprise to must use better device in producing a course, ask the final measure of all and important part is machined on numerical control machine tool as far as possible namely, in order to assure the consistency of spare parts dimension and appearance and accuracy. To fill cent produces the return rate of the largest investment of machine tool of every numerical control, when we are planning production, be rough machining arrangement as far as possible on general accuracy machine tool treatment, reduce the mental allowance of finish machining, finish machining is machined on numerical control machine tool, heat treatment platoon is between thick finish machining, reduce the loss of cutting tool, can make numerical control machine tool does a few parts more inside unit time so, let numerical control machine tool all develop the biggest efficiency with the best will in the world, create greater value. Match to numerical control machine tool with necessary tool, choose advanced and reasonable cutting tool, perhaps adjust process, decrease as far as possible change the auxiliary time such as the knife, raise the utilization rate of numerical control machine tool. For the function from numerical control machine tool, a lot of spare partses can be machined, but spare parts appearance each different, fixed position installs clip to have a problem, this provides suitable tool to numerical control machine tool with respect to need, assure to machine quality, reduce a spare parts to install time, make more spare partses can be machined on numerical control machine tool, improve treatment efficiency, also raised the utilization rate of numerical control machine tool so. Additional, the cutting tool with good quality is chosen as far as possible on numerical control machine tool, make the durability of cutting tool and cutting tool life rise, especially finish machining cutting tool, reduce the time that changes a knife and time. On the measurement of dimension executive trends is monitored, reduce what go up in the machine tool to detect as far as possible time, reduce auxiliary time thereby. CNC Milling
