Utilize old and useless lathe bed, bedstead of lathe, bed saddle, etc. base shelf part carry on transformation design, Economize lathe maintain the expenses, improve the recovery utilization ratio of the lathe at the same time not merely, It is the development trend that enterprises utilize in old and useless lathe future. The new post part of milling machine has adopted electrical machinery, moderating machine, transmission with wheel, Rotational speed of milling cutter that make keep and within certain range, reduce cutter work piece precision deviation that vibration cause. Put into hoist or lower spiral shell pole device and runner , make cutter entering giving amount can be regulated by hand vertical, Have improved the machining accuracy . Belt pulley office adopt simple and easy pieces of urgent device, can to lead wheel loose to take off, Skid phenomenon adjust, guarantee the continuity of the transmission. Through various kinds of comparison of scheme, draw and design not really feasible while being above- mentioned, Have improved the rate of recovery of the lathe , has increased the processing range of the lathe .
