I would call the National Kitchen an Bath Association. They are a non-profit representing the industry. I think, but I am not certain, that they are the right association. They may be more geared to sales than manufacture. You will have to ask
These associations maintain a database for their members. Ask if they have a trade show; when and where it is, and if it is geared towards manufacturing. If not, ask if they know of a trade association that does serve the manufacturing end of the business.
You are not imposing on them. They are there to serve its members and if you ask for a member list or a referral that can sell you an appropriate saw, that is part of what they are there for.
Also ask if there is a trade publication, and how to get a subscription. Most of those trade publications are free to industry members.
Or go online and see what other trade associations there are serving the manufacturers of kitchen cabinets. Ask them about trade shows, trade publications, and referral lists.
I used to be a subscriber (30 + years ago) to one of those publications. When I get home I will look to see if I still have a random copy. If I find one, I will report.
But remember that trade associations are there to support their membership and that would include referrals to people like you. It is their job to do this. You are not imposing on them.
