Thread: What Collet Chuck have I got?
What is a suitable coupling for 500 revs/second? :confused:
Balance probably isn't a prime consideration, but no bending parts obviously.
I'd probably go for a rod though one shaft engaging a pair of driving dogs on the other, then spend half an hour adjusting it 'till it ran quiet :D
Picked up a good set of engineers parallels 10 pairs x1/8" for £15 on eBay, a bargain I think.
Have decided to buy MT3 collets and a few other bits... (6" vice, some endmills, etc.), priced up from RDG they come to just over £250... any suggestions where else to check pricing?
Here's my shopping list - what should I add/leave off/change?
11-piece MT3 collet set (need to check drawbar size)
MT3 indexable face mill (need to check drawbar size)
MT3 keyless 1-16mm chuck (1/2" BSW drawbar)
12-piece set of metric end & ball mills
centre drill set
Vertex K6 milling vice
metric tap and die set
1 - 10mm in .1mm HSS drill set
Thats £362 (I added a couple of things!)
I was only slightly dubious because I web searched it and found two interesting thoughts. Some bod in Yankland saying an early 80's refurbed MH-600P was worth about $1500 so my bid was about right. Someone else saying his had crashed and the only thing coming on was the hydraulic motor.
Hydraulic motor :confused:
Also I'm changing units up on the industrial estate. My landlord has plans to turn my shop in to a building site over December and there was another one going that was warmer, drier, better lit and slightly cheaper to boot. I do like my creature comforts but probably best not to buy large milling machines until I've settled in.
I bought my set of ER32 collets and a #40 chuck for under a hundred on fleabay then sold the chuck so I got my collets for just over £70 which was good back then.
I already have a 48v 15A PSU and a 70v 9A one and the drivers I'll make myself... so its just steppers, ballscrews and other bits n bobs I'll need, but they'll have to wait a while...
