Making of corebox (cnc milling)

[@CncFrezar]

Hi guys. If some holders seem too long to you, you are right. It's that I'm very lazy and I don't want to set shorter holders.😀

I love this because ive just finished working on a 4 tool die for turbos with brand new core boxes to match (assuming these are for turbos too) small world!

Grosartige Arbeit , Sie benutzein kein Kühlwasser, überheizen die Werkzeuge nicht?

[@CncFrezar]

Thanks. We use air for cooling.

CIMATRON VERY GOOD!

[@cristinelpricop]

when programming, how you define all these high feed end mills? As a bullnose end mill? What stepover you usually use 50% 65% 80% of the cutter diameter ? What about plunging, you prefer to ramp down or just a simple plunge into the material? Thanks

[@CncFrezar]

Hello. We define as end mills, plunge into the material 5 degrees 30% of the total feed. ae 60%

[@TrPrecisionMachining]

very good job CncFrezar

[@ralphaverill2001]

Seeing the final products come out of the molds would be a nice finish to the video

[@CncFrezar]

You are right

[@mirohornik98]

Amazing video! 👍

[@CncFrezar]

Thanks son😁

[@yhsbu]

I still love to watch CNC machining videos, but I am glad I got out of the business. Customers were demanding NET 30 or greater. Metal that is supposed to be stable warping several ops into the job. Quoted for 20 hours of work and took 35 hours (working for free now). The customer gave you the job because you ended up being the cheapest shop. The list goes on. One of these days Ill get a CNC again and just make stuff for fun and leave the mortgage payment out of it.

Well done guys! I’m watching your channel for a while and I love your content. Could You tell me which CAM software do You use?

[@CncFrezar]

Thanks. I use Cimatron

[@ayushsharma7995]

Hi recently watched a lot for your videos, and they are satisfying. thinking of buying a used double column machine but it's my first VMC. Is machine from 2005 too old i your opinion. I don't have any experienced person to consult. Plz give me some advice.

[@CncFrezar]

Hi. That age is not that important. What is important is who worked on the machine and what it was used for. You need to do an accuracy test on it.

@@CncFrezar Хорошо, понимаю. Просто очень любопытно стало)

[@richardmiddleton7770]

Why high feed rate and shallow depth of cut over slower feed but deeper depth of cut? Surely the insert tip edge is doing twice as much work?

[@CncFrezar]

HF cutters are built for high feeds and small depth of cut

[@matamanufacturing8808]

Good video, congratulation. One question, how much thickness do you normally leave from the heat treatment to the final finish? And how much thickness do you leave for finishing with a ball tool?

[@CncFrezar]

Thanks! It depends on the size of the part. From 0,5mm to 5mm. We leave 0.05mm for finishing

[@vincentheredia2876]

can you indicate the parameters of drilling as well?

[@CncFrezar]

They were ordinary HSS drills. So nothing special.

Hi. Cool work. You don't use coolant for your milling heads because you are filming or you work this way? Would you say using milling heads for roughing is cheaper than say trochoidal with solid end mills? You can definitely reach longer wth your tools though. Vc and Fz would be nice to know too, but I'll take what you show too :). All the best! Subscribed

[@scheatt1308]

Often, shells mill don't need coolant. Or just air blow. Coolant force you to decreased Vc and Fz because the coolant create a thermal shock.

[@CncFrezar]

We use air for cooling. In the next video, I might try to write Vc and Fz as well

[@syringavulgaris3258]

@@scheatt1308 Tried air cooling with two different shell mills. Shocked by how much longer the inserts last. Thanks
