Most machine shops don’t realise they’re losing money until the job is already unprofitable.
It usually doesn’t start with a big failure. It starts with small inefficiencies:
Tool life that’s “acceptable” but inconsistent
Cycle times that creep up over months
Operators making small adjustments to compensate
A finish that just about passes inspection
Individually, none of these look serious.
But together, they quietly destroy margin.
In many cases, the machine gets blamed first. New spindle, new machine, new controls… when the real issue is sitting in the tool holder.
At Prima Tooling, we see this pattern regularly. A small change in tool geometry, coating, or design can completely change performance without touching the machine.
Custom tooling is not about being “specialist for the sake of it”.
It’s about removing hidden inefficiencies that have become normal in day-to-day production.
If your process hasn’t been reviewed in years, there’s a strong chance you’re not running as efficiently as you think.
Sometimes the biggest gains come from the smallest tooling changes.
If you want a second opinion on a machining process, we’ll happily take a look.
