The Typical Features and Advantages of CNC Camshaft Grinders

Camshafts are important parts of automotive engines and other internal combustion engines, and their processing quality directly affects the quality of automobiles. At present, many manufacturers in China still widely use ordinary grinding processcamshaft, this kind of camshaft grinding processing method is difficult to meet the modern automotive industry parts processing high precision, high efficiency, high flexibility and process concentration requirements. Cnc cubic boron nitride (CBN) camshaft grinders with high precision, high efficiency, high flexibility, process concentration and so on, has been gradually used in the modern automotive industry. There are two forms of CNC camshaft grinders due to the different methods of CNC forming. One is the polar coordinate type: i.e. the workpiece turns, the grinding wheel frame is fed to form the cam profile.

Today we will use the North two B2-K1016 type CNC camshaft grinder to introduce you.

B2-K1016 type CNC camshaft grinder using CNC two-axis interpolation linkage, the grinding wheel feed shaft (X-axis) and workpiece swing shaft (C-axis) full-closed loop feedback control, to achieve cam non-circular surface cnc precision positioning movement, completely solve the traditional mode processing machine processing flexibility difference, mold processing difficult, maintenance complex shortcomings. CBN grinding wheel line speed 120m/s, C-axis and X-axis are using international advanced direct drive technology, mainly used for internal combustion engine camshaft-type parts cam-type face of large-volume precision processing, the front side of the machine for the vertical plane without any adjustment link, suitable for adding parts logistics transmission line, no interference with each other, is suitable for the production of assembly line preferred equipment. Machine tools comply with relevant national and international standards in safety, environmental protection, ergonomics, etc.

Mechatronics structure layout, overall protection, maintenance convenience in line with the requirements of human-machine engineering.

The CBN grinding wheel is driven directly by the static piezoelectric spindle, and has the characteristics of high swing accuracy, good precision retention and strong rigidity. The CBN grinding wheel line has a speed of up to 120m/s and is equipped with a built-in dynamic balancing system.

Three-axis linkage feed, head frame (C-axis) directly driven by torque motor, positioning accuracy of 0.002 degrees, grinding wheel frame (X-axis) directly driven by linear motor, dynamic correspondingly good, zui high speed up to 40 m/min, workbench (Z-axis) driven by servo motor, zui small set unit of 0.1 m, zui high-inspeed speed up to 20m/min.

The 120m/s CBN grinding wheel is closed with a diamond wheel and is equipped with sonar detector to ensure a small amount of precise rest and extend the service life of the CBN grinding wheel, which is driven directly by the electric spindle.

The use of imported advanced numerical control system, with grinding process process transformation, workpiece quality management, machine condition monitoring, fault self-diagnosis and abnormal alarm control function, menu interface input is simple.
