Jig Borer Vs Mill Html

jig borers or just as the name implies they were built to bore very accuate holes at very accuate locations they were not built to handle the side loading that a vert mill is designed for you can do the same thing in a vert mill as you can do in a jig bore but not with the precision

a jig borer is a hell of a machine but it x27 s not magical you have to use the same sweat and technique dialing in the existing references as when using a turret mill once dialed in of course the jig borer is capable of an honest ten times closer rolerance for positioning and geometry of machined features if that x27 s what you truely need

moore no 3 and 1 1 2 jig borers have inverted v ways on the x axis sort of like a lathe so the only thing holding the table down is the weight of the table and to some extent the screw and nut assembly some older models such as original linleys and perhaps the atlantic do have dovetail ways and are more like a mill

depends on the jig borer even the age the early linley x27 s for instance had dovetail ways whereas the later models were like moore and had v ways the v way machines ability to mill is limited by weight of the table

jig borers are different from a typical knee mill in two important ways fine thread leadscrews with finely divided handwheels and reducing gears or high resolution position encoders this allows them to work down to divisions that a typical mill can x27 t resolve and thus they can position very accurately

i x27 m not familiar with a lindley machine only newall and sip but jig borers are extremely accurate machines capable of holding very tight tolerances e g 0001 quot you can mill bore drill etc etc and hold positional tolerance and size to close limits but you do of course need equally accurate kit to go with the machine

quot in many cases a jig borer is a x27 jig eliminator x27 in other words such a machine may be used instead of a jig either when the quantity of work is not large enough to warrant making a jig or when there is insufficient time for jig making quot several innovations in the development of the jig borer were the work of the moore special tool company

on a moore jig borer the table and saddle stack up like pringles on the knee there x27 s no dovetails merely v ways without retainers meaning there x27 s nothing to restrain the table or saddle from lifting given a hard enough sideways push or lift so as long as you don x27 t get rambunctious yes you can do light milling on a moore
