How to choose the hardness of the grinding wheel for CNC cylindrical grinder
Date: 2016-03-08Read: 8
  CNC cylindrical grinderMainly used in the preparation process of bar materials, in addition to processing punching needles
Ideal machine for complex shaped molds and workpieces with large aspect ratios
The multifunctional robotic arm and online measurement options facilitate small batch production to long-term unmanned automation operation The professional grinding wheel balance force grinding process is a mature technology that ensures the concentricity of workpieces Five axis linkage can grind flat and non-circular cam surfaces
Numerical control grinding software can achieve synchronous high-speed precision grinding of coarse and fine grinding axes The optional grating ruler can improve interpolation accuracy, ensuring high precision and surface roughness effect for conical and circular grinding of parts
Characteristics of CNC cylindrical grinding machine:
◆ Diameter grinding
When producing in small quantities, automatic feeding combined with a spark free timer can achieve good grinding quality When producing in large quantities, the two-stage automatic feed and two-stage measuring device (special attachment) can provide * output and grinding effect (NC/CNC models)
Horizontal grinding
The automatic intermittent feed and hydraulic driven worktable enable the workpiece to achieve the most effective transverse grinding
End face grinding
Remove the rotating cover of the work spindle head, replace it with a three jaw or four jaw chuck, change the position of the positioning tip to rotate the chuck, and fix it at a 90 ° position for end face grinding
Shoulder grinding
When the outer diameter of the workpiece and its shoulder need to be ground in one go, the workpiece is supported by two centers and the grinding wheel is modified to the right of the grinding wheel head and rotated by one angle to grind
◆ Slope grinding
The workpiece can be supported by a clamp or two centers, and both the worktable and grinding wheel head can rotate and be easily adjusted
Internal diameter grinding
Inner diameter grinding attachment (special attachment) can grind the inner diameter by simply pulling down the inner diameter grinding spindle and fixing it in the grinding position
How to chooseCNC cylindrical grinderHardness of grinding wheel
CNC cylindrical grinding machines are extremely common in mold factories and hardware processing factories, and have become a commonly used equipment for technicians in the mechanical industry. In operating cylindrical grinding machines, the selection of abrasives is very important
The harder the grinding roller surface, the softer the hardness of the grinding wheel should be selected
(1) If the grinding wheel wears out too quickly, it indicates that the grinding wheel selected for a specific processing roll is too soft. The following improvement measures can be taken:
A. Improve the linear speed of the grinding wheel;
B. Increase the longitudinal feed rate of the drag plate, that is, the longitudinal feed rate of the drag plate per rotation of the workpiece is increased to 2/3-3/4 of the width of the grinding wheel;
C. Reduce the speed of the rolling mill
If no significant grinding effect is achieved after taking the above measures, it indicates that the grinding wheel is too soft and not suitable, and a harder grinding wheel should be selected
(2) If the grinding wheel is significantly obstructed (difficult) or very dirty when grinding the roller, the passive sand particles are not easy to fall off, the grinding wheel is prone to sticking with debris, and the grinding roller surface is burned or scratched, it indicates that the selected grinding wheel is too hard. The following measures can be taken to improve it:
A. Reduce the linear speed of the grinding wheel;
B. Increase the roller speed
If no significant grinding effect is achieved after taking the above measures, it indicates that the grinding wheel is too hard and a softer grinding wheel should be selected
4. Selection of Grinding Wheel Bonding Agent for External Grinding Machine
Except for the use of resin bonded grinding wheels for mirror grinding, ceramic grinding wheels are preferred for all other types of grinding on the roller surface
