RS7 Joint Grinding Machine
HOW DOES THE RS7 OPERATE ?
The RS7 is a flat- and hollow grinder for grinding mould joints after repair.
The machine is manual in order to allow taking away material only where necessary.
The mould is positioned on a magnetic holder with V-blocks.
The mould can be adjusted in 2 directions to make sure that the joint is perfectly parallel with the table of the machine: the mould can be axially adjusted in the V-blocks with a gauge and mould & holder together can be longitudinally adjusted with a comparator.
The hollow grinding is obtained with a copying device and a template at a scale of 10:1 for depth and 1:1 for length.
The profile of the template is +/- 1 mm deep and can be made easily and accurately enough with a file.
ADVANTAGES OF THE RS7
- Perfect positioning even of moulds with a damaged band diameter.
- Less material is removed than with a milling machine: longer lifetime.
- Time saving compared with manual repair with a file.
- Better joint quality than with manual repair, no burrs.
