Vertical CNC Gear Profile Form Grinding Machine Advantage:

The  QC build philosophy is  to design a  machine  using the  best  of  what  has  been proven to work on previous  (smaller) designs  and then start  with a  design unencumbered by prior constraints.   The #73200 is not the largest machine that QC has built, but it is the largest stock ‘standard’ commercially available machine to date for external form grinding.   With features designed from the beginning to facilitate ease of loading and unloading large and varied workpieces, the #73200 uses similar grinding head designs  from  its  smaller siblings, the  #7380 and #73125, but  houses these components in a more robust head and column assembly, along with a 40KW (54 HP) grinding spindle and a 1,250,0mm (49.21”) tip diameter capacity.   Heavier ways  and a  more  modular enclosure  are  also used to make  for a  longer lasting  machine  capable  of  up to 1000,0mm  face  width (40”) spur gears.   Like  its  smaller brothers, #7380 and #73125, the #73200 utilizes a one-bed design, ribbed casting for ease of installation and overall stability.
The  #73200 also utilizes  the  same  software, on-board inspection capability and PC-Based NUM controls package as its smaller brothers and does come standard with inspection measurement and printing capability featuring Renishaw equipment.   This design also utilizes  Accoustic  Emission (AE) monitoring equipment  in conjunction with a  dynamic  wheel  balancing system  for enhanced grinding operations  including grinding monitoring and anti-collision.
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  and software  package designed with a  graphical  interface  to simplify complex profiling requirements.

Vertical CNC Gear Profile Form Grinding Machine Major Characteristics:

Main Characteristics 
· Compact machine design featuring a ribbed, one-piece cast iron bed. 
· Column, carriage and workpiece table utilize a constant flow hydrostatic guideway system. 
· Ergonomic  design  with  complete  machine  access  from the  ground  floor and through a well designed   and completely lit enclosure. 
· Flexible  workholding area to accommodate  all  manner  of customer  workpieces up to 1750,0mm in height (68.89”). 
· The on-board automatic dressing cycle of the grinding wheel improves the  uptime  and  efficiency of this  machine  tool.        Using customized  QC  Software with a conversational format, profiles of the grinding wheel are easily modified. 
· NUM (Swiss Made – USA Serviced) 1050H PC Based CNC control with  Eight (8) independent axes of control.
· Integrated  Schmitt Industries  (SBS  –  USA) dynamic  grinding wheel balancing system for greater control of the grinding and dressing process.
· 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 work  piece  parameters  and relevant technical parameters as called out by the operator.
