    Default Anyone have experience with a YCM vertical milling machine?

    We are looking to purchase some new machines and are considering this brand. Looking for any feedback you may be able to share. TIA

    Next time try Google search for reviews on it first. Link below is a 6 year old thread.

    Google search "YCM vertical milling machine reviews."

    I programmed some of these at a shop a few years back. They were new. I liked the machines and would not have any issues buying one. They were fast and reliable (except when the setup guy decided to rapid into the table). Yeah, it was one of those shops where instead of reading manuals, the guys would sit on their cell phones researching guns and porn. They would literally crash something 1 to 3 times a day, every day. They didn't even bother putting tapered pins in their lathe turrets anymore. The operators liked them as well. I am not sure about the costs compared to a Haas.

    Yeong Chin Machinery is one of the better builders from Taiwan.
    They have strong financial backing so they don't build them as cheaply as some others.
    It has been several years since I worked for them, but the culture of the company has likely stayed the same.

    I will go back to my standard queston. Why that make? Of all the machines available, why YCM?

    Why not YCM over another? Personally, I would sooner choose Haas because of service and user friendlyness. But I would sooner choose YCM over Doosan or other fanucs.

    Worked at a shop with only YCM mills. they ranged from 5-10 yrs old. I liked them pretty well. They had Fanuc controls. Easy to use if you know fanuc.

    we are looking for the best value. we need about 10 new (large) vertical machine centers for a new program we won. We don't currently do any machining although i have owned a business previously where we did some. Obviously we have looked at HAAS machines and there are some advantages there. That said this is a big investment and we want to make sure we make a good choice. Why YCM? Good question...i guess because their sales guy reached out to us and is making a compelling case. We don't need high precision, or even long life (this is a 3-5 year program) so don't really want to go with more expensive (better quality?) machines.

    What material are the parts? What size of parts do you consider large? What quantities? Does a pallet changer on a HMC make more sense running 24/7? How many operators are you planning on using? Is the machining going to be used the majority for hogging or is there more finish, drilling and tapping? I have nothing against YCM. I cut my teeth on selling that product. If you are really looking at up to 10 machines, it makes a whole lot of sense to look at alternatives that may take less spindles and less man power. Support is important but how much support you need is also a critical factor in choosing the machines.

    Anyone else think this is a risky endeavor? Limited machining experience on staff and taking on a multi year contract requiring a million dollar or so investment.

    Happens ALL the time. Seriously, I used to see this a bunch when I worked for an MTB.

    Could we get this back to the topic of YCM specifically though? I have been window shopping for one for years. Some of their products look very compelling, and I have yet to hear anything bad about them.

    But have you heard anyone say much great? I sold a hundred or so in my younger years. Decent middle of the road iron with a plain jane Fanuc on them. Had some issues with the lathes not having hard enough ways. Other than that, meh.

    The incentive for me is that they will stick a Siemens controller on it. I know a couple folks who have them (YCM with Siemens), who seem to like it. I like the BBT spindle too - IIRC you can get a 15k or 20k DD on a 40 taper, and they have a really nice torque curve.

    Trying to spec out something comparable through DMG MORI (40x20, 20k, Siemens), it was over double the price of a YCM, and well out of the range that any sane person would spend for a "regular" VMC.

    thin walled aluminum extrusions. 24" wide x 2" tall x 60" long. a couple tool changes, no tapping, just mainly rough cut removal of some material, low tolerance requirements. around a 3-4 min cycle time (projected by HAAS). we would love fully automated but i'm not sure the vacuum fixture is enough to keep it from chattering. so if we have a more robust fixture we may need to have operator assist. just under 1m parts per year. The machining is only part of a much larger program...this is a small piece of the pie but one we need the most help with.

    we will likely have to probe 4-8 places on each part...i like the fast rapids on the YCM.

    Perfect Chiron long bed work, where they split the fixed table into two work zones. Cut one side while you load the other. Chiron would probably get the cycle down under 2 minutes. BUT>>>>> Not cheap.

    Fryer and Kent make something similar.
    High Speed High Speed Traveling Column VMC - Kent CNC
    Fryer Machine Systems Inc. - CNC toolroom lathes milling machines machining centers

    For those with deep pockets.

    Why not a specialized extrusion machining center like a Modig? HHV2 - Modig

    Edit: Okay, you can ignore that...they can only feed 10" extrusion. Carry on.

    I looked a YCM lathes a little bit, they seem like nice machines and looks like they go cheap used. The TC26 model would fit my needs almost perfectly. Except it has a gearbox and spindle sounds like crap. I dont know why they couldn't just make it belt drive like everybody else does.

    Every time I run my Colchester manual lathe it reminds me to NEVER buy a cnc with a gearbox lol.

    Curious on what kind of lead time they gave you? I quoted a basic lathe here in Taiwan a couple weeks ago with YCM and got told minimum 120days. Visited a few other local manufacturers and everybody is busy like crazy building machines. Quite a few mentioned possible electronic parts shortages that may cause delays as well.

    I don't have the info yet but it's valid. Everyone has crazy lead times because the economy is so bad that there aren't any jobs and so our government has to send everyone checks...but i digress. We will probably end up buying used machines, at least to get started. there is a ramp so we can get by for a while with a few machines.
