Worm Grinding Wheel grinder Advantage:

The  Model  #YK7340A CNC  Profile  (Form) Wheel  Gear  Grinding  Machine  is  used  for grinding precise,  special  cylindrical  gears  with  an  outside  diameter  of  less  than 400mm (15.75”). These  types  of  gears  are  more  commonly  used  in  the  automotive, rail transport, aviation  and  machine  tool  industries.    This  machine  is  especially  suitable  for  grinding high-speed gears and clusters with requirements for profile and lead modification, as well as special  fillet  requirements  for tip  and  root.  These  machines  can  also  be used  for  grinding components without involute forms as well, such as cycloid gears, precision splines and worm  workpieces.    Indeed,  the  YK7340  was  specially  developed  to  encompass  these  special  workpieces.

The  working principle  of this  machine  is  form grinding.   The  profile  of the  grinding   wheel  is modified   via  on  an on-board wheel  dressing system utilizing a diamond dressing wheel to facilitate grinding of  the  orkpiece tooth    forms    precisely.  The movements  and operations  of the  machine are relatively  simple  and straightforward  (especially when  compared  to generational-type grinding); but can be characterized by  tremely high machining accuracy and efficiency.   The model #YK7340 orients the workpiece horizontally between centers for maximum workpiece  design  flexibility. This  design  philosophy  more  easily  allows  for spline and worm gear forms. 
 The  Model  #YK73xx  Series  form  grinding  machine  designs  from  QC  American  are  known for  their  remarkable  reliability,  thermal stability  and  they  are adaptable to  automation. Featuring  a  full  CNC-based control,  these  machines  are  capable  of  performing well  in a variety of gear finishing applications, as well as being quite flexible where modifications are concerned. The #YK73xx  Series  feature  high  power  grinding  spindles,  standard  precision components  utilized  from  around  the globe and  closed  loop  feedback  systems  for  high geometrical and positioning accuracy. 

Worm Grinding Wheel grinder Major features:

 ·   Compact machine design featuring a ribbed, one-piece cast iron bed. 
·    Ergonomic  design  with  complete  machine  access  from the  ground  floor and through a well designed and completely lit enclosure. 
·    The on-board automatic dressing cycle of the grinding wheel improves the uptime and efficiency of this machine tool. 
·    Siemens 840D CNC Controls and Drives – controlling six (6) axes.
·    The  special  Human  Machine  Interface  (HMI) was  developed  by QC according to the  working characteristics  of North  American  gear processing. Based  on  a conversational  programming protocol, programming is  simplified  by entering workpiece  parameters  and relevant technical parameters as called out by the operator.
