JGS emailed me reamer prints, and answered questions with little delay. I will probably make an order tomorrow. They close at 2 pm?? I had no idea they closed that early!
Most CNC machines will go back and recut for flex in boring bar or wear on tooling. At least my buddy's does. MattI can see single point cutting could work with larger calibres but I suspect tool rigidity might be an issue with smaller calibres. I guess very high speeds and ultra light cuts would be in order.
Yep that is who I am talking about. He just made me dies not long ago. That machine threaded and cut them that fast it was unbelievable. MattDusty -
Back in 2007 already, Phil Bower set a IBS-1000 record in HV-Gun for Group with a CNC single point cut chamber.
In the industry, I believe all Tikka and Sako chambers are being single point cut as well.
Attaching a picture of a boring-bar used to single-point cut chambers. That particular one will do 243/6mm throats and/or larger.
An innovative future is what foresee....

Aren't they great to do business with?! Someone at the range recommended them, and I'm quite grateful.Just ordered two reamers from JGS, what a pleasure so far! Cheaper than ordering a cnc lathe!

One of the setups I've seen is with a Haas T1 using a 6-jaw chuck, in front of True Bore Alignment System. On the carriage, a drill bit, a roughing boring-bar, and the finishing boring bar. Like 10-minutes start to finish from dialing, indexing, to chambered !.!.!
The best surface finish chambers I've ever seen (particularly the throats).

You mean $30,000 to $500,0000, don't you?As to the CNC.....well, it's like this: the CNC machine is anywhere from $10,000.00 to $20,000.00 plus...a reamer is $100.00 to $125.00. Do the math!!! There will be no reamer companies closing down anytime soon fellas!!!
