Fixtures are not accessories in CNC / VMC machining — they are process control tools. No matter how accurate the machine is, without a proper fixture, accuracy cannot be repeated. • A fixture’s real job is not just holding the part. It locates the component precisely, resists cutting forces, and ensures repeatability across hundreds or thousands of parts. • Higher productivity in CNC machining does not come from faster spindle speeds alone. It comes from reduced setup time, consistent positionin
