Adjustment of gaps in the support of the lathe MN-80

Shown is the adjustment of the clearances in the support of the MN-80 lathe. It is shown in detail how the cross feed and longitudinal feed of the swivel support are arranged and controlled.

Both the position of the wedges and the gaps in the screw-nut connection in both feeds are adjusted with screws. No disassembly. The axial clearances of the lead screws of both feeds are also easily adjusted with screws. Only first you need to remove the handles and limbs. This will open access to the adjusting screws. These adjustments are described in detail. I disassembled the transverse and longitudinal feed and show the adjustment points. For both the transverse feed and the longitudinal feed of the rotary slide, it is necessary to adjust two clearances: axial clearances in the lead screws and clearances in the lead screw-nut connections. The designs of both feeds are similar. At the cross feed, the lead screw is screwed into a split nut, which is secured to the upper part of the caliper with four screws. To reduce the clearance in the thread of the lead screw, the split nut must be squeezed. To do this, you need to tighten a special screw. This will reduce the diameter of the thread in the nut and the screw will rotate more tightly. Before adjusting the axial clearance in the cross feed screw, the handle and the dial must be removed. This axial clearance is adjusted by the position of the locating ring. And this position is determined by the protrusion of three special screws and is fixed with three fixing screws. It is better to make this adjustment disassembled so that the friction in the dovetails does not affect the ease of rotation of the lead screw. It is also described in detail about the longitudinal feed of the rotary support. At the upper slide, the lead screw is also screwed into a split nut, which is fixed to the movable part of the upper slide by four screws. To reduce the gap in the thread, the split nut must be squeezed with a special screw. But the fixing screws prevent this. Therefore, before tightening the nut, it is necessary to loosen these fixing screws. The adjustment of the clearances in the dovetails of the transverse and longitudinal feeds is adjusted using wedges - screws. Also, with the help of a wedge, the gap in the bed guides is adjusted - also with screws. There is a video about adjusting this gap on my channel:    • Токарный станок МН-80. Как УСТРАНИТЬ ...   This is how, quite simply, the gaps in the support of the MH-80 lathe are regulated.
