Prototype and Short-Run Production
Triangle Grinding’s focus on both large quantity production as well as both prototype/short run production runs make us your ideal partner for all your centerless grinding needs.
Through Feed Centerless Grinding
In through-feed grinding, the part rotates between the grinding wheel and a regulating wheel.
For through-feed grinding, one or both wheels of the centerless grinding machine are canted out of the horizontal plane. This imparts a horizontal velocity component to the work piece, so that outside feed mechanisms are not necessary.
The grinding wheel is canted with respect to the other two axes so that a component of its surface velocity pushes the part in the direction shown below. This auto feeding characteristic is useful for rapidly processing many parts in quick sequence.
Because of the axial movement, through-feed parts can only have right circular cylindrical ground surfaces. The wheel cannot be dressed to grind more complex shapes.
Through-feed grinding is primarily a mass-production process because of its high throughput.
In Feed Centerless Grinding
In-feed grinding differs from through-feed grinding in that the part is not fed axially so that the ground surface does not need to be a right circular cylinder. The grinding wheel can be dressed to accomodate the part. Once the work piece part is in place, the grinding wheel is fed in radially.Because of the set up time involved for each part, in-feed griding does not have the high throughput of through-feed grinding.
