CNC
CNC (Computer Numerical Control) This process is used on WIP (work in progress) die-cast parts or straight from a block of pure metal. The accurateness of CNC processes can range from 0.05 to 0.0005 mm. A thickness of a human hair is 0.07, hence this is very accurate. A computer program is pre-written, and the machine follows the cutting of the part every time.
There are many types of CNC machines, but most commonly are the CNC mill and CNC lathe At On Hing Metal, we use both of these machines.
According to ISO 5725-1 the general term "accuracy" is used to describe the closeness of a measurement to the true value. When the term is applied to sets of measurements of the same measurand involves a component of random error and a component of systematic error. In this case trueness is the closeness of the mean of a set of measurement results to the actual (true) value and precision is the closeness of agreement among a set of results. In order to have the most accurate and more precise measurements to CNC an object to accurate tools / appropriate speed and most importantly 4 axis / 5 axis CNC fixtures.
With modern CNC machinery, and experienced machinests, while serving many industries, from single part prototyping, to volume metal widgets, On Hing Metal is precise, reliable and committed.
The CNC materials commonly used at On Hing Metal is aluminium, stainless steel, magnesium, zinc and copper. We focus on eliminate any waste, (simplifying movements and optimising material usage), in order to give the faster cycle time, hence better pricing. Moreover, we are equipped in handling very tight tolerances and making thin small wall sections.
The advantages using CNC over other metal fabrcation
no expensive tooling cost involved (depends on the structure, as there could be complex fixtures involved)
