Process design principles

Process design principles 

  Design Technology program should be to ensure product quality at the same time, give full consideration to the production cycle,Cnc machining  cost and environmental protection; based on the enterprises ability to actively adopt advanced process technology and equipment, and constantly enhance their level of technology Engine block machining process design should follow the following basic principles:

 (1) The selection of processing equipment, processing equipment, the principle of selection adopted the principle of combining rigid-flexible, processing each horizontal machining center is located mainly small operations with vertical machining center, the key process a crank hole, cylinder hole, balancer shaft hole High-speed processing of  high-precision horizontal machining center, Cnc machining an upper and lower non-critical processes before and after the four-dimensional high-efficiency rough milling and have a certain adjustment range of special machine processing; 

 (2) focus on a key process in principle process the body cylinder bore, crankshaft hole, Balance Shaft hole surface finishing and the combination of precision milling cylinder head, using a process focused on a setup program to complete all processing elements in order to ensure product accuracy The key quality processes to meet the cylinder capacity and the relevant technical requirements;

  (3) All fixtures are used hydraulic clamp, clamping components, hydraulic pumps and hydraulic control components used in Germany or the United States producing high quality and reliable components;

 (4) The whole line used in all wet processing, using standalone BTA, high-precision machining processes critical horizontal machining center with constant cooling and to install high-precision high-voltage double-circuit band-pass fine filtration system, all with high-pressure processing center in the cold.  According to the technological characteristics of automobile engine cylinder block and the production mandate, the engine block machining automatic production line is composed of horizontal machining center CWK500 and CWK500D machining centers, special milling / boring machine, vertical machining centers matec-30L and other appliances. 

 (1) top and bottom, and tile covered only the combination of aperture rough milling machine dedicated to this machine to double-sided horizontal milling machine, using moving table driven parts, machine tools imported Siemens S7-200PLC system control, control cabinet set up an independent, cutting automate the process is completed and two kinds of automatic and adjust the state;

  (2) high-speed horizontal machining center machining center can be realized CWK500 the maximum flow of wet processing, but because of equipment, automatic BTA treatment system through the built-in tray under the wide-type chip conveyor and the completion of the machining center can be dry processing; machine tool spindle speed 6000r/min, rapid feeding speed 38m/min; 

(3)The combination of front and rear face rough milling machine tool using hydraulic transmission; control system imported Siemens S7-200PLC system control, machine tools have a certain flexibility;

 (4) The special machine TXK1500 this machine vertical machining center by the modification of shape, Cnc machining with vertical machining center features and performance, this machine has high strength, high wear-resistant, high stability, high accuracy, high-profile etc.;    

  (5) high-speed vertical machining center matec-30L of the machining center spindle high speed 9000r/min. Control system uses Siemens SINUMERIK840D control system;  

  (6) high-speed horizontal machining center spindle CWK500D highest speed 15000r/min
