■Spindle units for the Swiss-made VOUMARD 5A internal grinder
 Large numbers of the VOUMARD 5A have been imported into Japan over a number of years. However, the manufacturer has recently ceased production and replacement parts have become difficult to obtain.
A very user-friendly machine with an extremely high level of precision, the VOUMARD 5A is still widely used in Japan.
Given this situation, we have commenced production of spindle units for the VOUMARD 5A to enable ongoing repairs to be made to this excellent machine. The spindle unit makes an ideal replacement part.
