CNC Machining in Cikarang: Basic Steps To Precision Components. CNC machining in Cikarang is thriving, thanks to the many advantages the process offers both manufacturer and consumer. We are CNC Machining Service in Cikarang.

Great speed and accuracy allow for mass production of parts and maximization of profits. This is good news for business, and it means greater availability of product and lower prices to the customer.

But the process is often confusing to observers, due to the many variations on the basic CNC machining model. For those who wish to understand more about Computer Numerical Control machining, here is a rough guide to the basic process.

Beginnings: Design

First step: create or review the blueprint of the part to be machined. (Sometimes there will an actual part to be copied, rather than a blueprint.) From here, designers must create a process flow plan, from raw material to finished product.

Next, the fixturing for the part must be located or designed. Now the most complex component of the process: a designer must create a computer program to power the CNC to machine the part. This program may control factors such as feed rate, coordination, location and speeds.

A CNC program is written like a sentence, with the order of operations in chronological order. The machine will then execute that set of instructions, one by one. (CNC codes begin with letters like S for spindle speed, and X, Y & Z for common linear axis motions). When certain codes are arranged together in a coherent method, this group of CNC codes create a “command.”

Intermediate: The Shop

Schedule CNC machine time. The machines can normally be run 24/7 with only minimal supervision (and occasional downtime for maintenance.) Order and inspect raw materials required. If necessary, pre-process raw materials. This may include casting, if this is to be done on-site. Set up and offset tools, fixture, and machine.

Final Steps: The Product

Test and run first part. This is sometimes known as an “air test” or “cutting air.” Quality check. Engineers must carefully inspect the initial part to ensure it will function correctly. Reset specs if required. Run the rest of the parts through the machine. These will be exactly the same as the initial part. Finishing (grinding, burr removal, etc.) Final inspection. Ship out the parts.

The Tools

Tools which can be controlled by CNC programming include: drills, lathes, milling machines, wood routers, electrical discharge machines, sheet metal turret punches, wire bending machines, hot-wire foam cutters, surface grinders, cylindrical grinders, and induction hardening machines.

The most common tools used are milling machines and lathes. A milling machine is basically a rotating cutter and a table. By moving the table and the cutter relative to one another, complex cuts can be made.

Lathes spin solid objects and then use tools symmetric to the axis of rotation in order to cut. “Machining centre” often refers to a combined milling machine and lathe. Another commonly used CNC machine is the EDM, or electrical discharge machine, which creates cavities using electric sparks.

By using CNC machining, parts can be manufactured with great speed and accuracy, making the process essential in today’s electronic world.
