I'm looking for the best power and price on a 13X40 or a14X40 gear go before metal lathe?
I looked at alot of lathes, but not sure of the lathes quality. If I know the quality, Ican engender a better choice on buying one!!
Thanks
Answers:
The basic, time tested, bottom line, rule is -- you bring back what you pay for.
A cheap lathe or a cheap hammer is -- cheap. As next to anything, reliability and precision is what you want. The more bells and whistles involved, then the more precision within the working parts is required. Reliability and precision takes skiill and workmanship to produce. Exterior appareance i.e. machining/finish is an indicator of the interior milling, machining, and precision the manufacturer requires for its products. You hold to decide how much of those things are you willing to sacrifice for a lower cost?
You should consider built within safety features like the sanctuary clutch in the apron that kicks out the nurture and the feed/threading safety interlock eliminating the simultaneous engagement of the nurture and threading motion. Other things to look for are lathes with a cross ribbed headstock for added strength and stability. Anti-friction mounted shafts and dynamically balanced components. Hardened and ground alloy steel gears, shafts and splines. Oversized precision chrome alloy spindle next to a big 2-1/4" thru hole that is mounted in double row angular contact thrust bearing and 2 double row roller bearings.
Look for swing over the cross slide, and swing in the crevice. Hardened and precision ground bed ways on a heavy one-piece close grain imprint bed that is fully ribbed for maximum stability and even thermal expansion. Quick-change gearbox for cutting Metric, Module and Diametral Pitch threads as ably as standard American threads.
Should have high speed for simplified machining, and plenty of power for heavy roughing cuts. Is the headstock dynamically balanced?
Pay attention to the direct-reading micrometer dials. Is near play? Easy to read?
What equipment do you get or is available? Such as:
Back plate, like 5 7/8" dia, D1-4
Inch leadscrew
Instruction/maintenance guide
Table chip pan
Thread dial indicator
Tool kit
Set of metric swing gears
Two #3 MT hardened centers
Feed rod and double-wall apron
Six position turret
Follower rest
Steady rest
Handwheel 5-C collet attachment
Handlever 5-C collet attachment
Metal cabinet with tray top
Micrometer carriage stop
Milling attachment (inch)
Four-position horse-drawn carriage stop
Set of 15 5-C collet for 1/16" to 1" in sixteenths
Telescopic taper attachment
6" 3-jaw universal chuck
8" 4-jaw broad chuck
Six position bed turret
10" Face plate
Round tool post
4-way tool post
1/2" drill chuck
Live center
Digital readout
Quick change tool post with holders
Coolant container and pump
Special electrics
