The PM-728VT CNC Mill is one of the most popular hobby mills out there. So we decided that it needed a conversion kit that would out perform the kits that are available today, By adding Double Ballnuts to our ball screws we have doubled the accuracy to the kits that are now available today. We also added sealed bearing on all the axis's to make this the BEST PM-728VT KIT ON THE MARKET with .0015" accuracy! We have tested this kit in production use for over a year now with great results. We packaged ALL this at a very competitive price. You will not find a better kit on the market for the price.
