Our WCS option gives you 18 individual part zero positions. Each zero point can be adjusted at any time. The control remembers the positions so there is never a need to reset, even in the event of a power loss. Many uses, this feature allows you to have multiple zero locations in memory. Each vise or fixture can have its own zero point. With WCS you can interupt a job run, set another vise up on the table with new zero, machine that job and return to the original job all without distrubing your original zero point. this is just one example of a time saving use of WCS.
