Manual Machining
Like many skilled trades, the art of manual machining is slowly dying out. This is because the world is moving towards technology, like CNC machines. As much as this technology is great at automating tasks, they lack the skill and eye for detail of a manual machinist. A manual machinist can also mill or turn to precise dimensions, unlike a CNC-programmed device.
Here is everything you need to know about manual machining, CNC machines and how they work.
What is Manual Machining?
Manual machining is a process where items are made by hand using tools such as manual lathes, drill presses and pocket milling machines. Think of it as crafting or building something with your hands, but instead of just using your hands, you use tools to shape metal or other materials into the desired shape or size.
Manual machines are operated by skilled professionals, hence the name "manual machines". There is machinery available that does this without the need for a human operator, like CNC machining services. However, we believe that manual machining is still the future, as there is currently no technology available that matches the skill of a trained worker.
How to Machine Metal
To machine metal, you usually use the following step.
- Prepare: Choose the right type of metal and clean it. Then, secure this metal to the machine so it does not move or cause a hazard during the cutting process.
- Select the tools: Choose the appropriate tools for the job, such as drills, drill presses, end mills, and manual lathe-cutting tools.
- Set up the machine: Adjust the speed and feed rate on the machine to match the type of metal and tool being used.
- Start the machining process: Turn on the machine and begin cutting, shaping, or drilling the metal.
- Monitor progress: Continuously monitor the cutting process to ensure that the metal is being machined accurately and to make any adjustments.
- Finishing: Once the machining process is complete, inspect the final product to ensure it meets the desired specifications.
What is CNC?
CNC is an abbreviation for 'Computer Numerical Control'. It's a type of process that uses computer software and specialised machinery to automate the production of parts and products.
In a CNC system, like in a CNC lathe, the machine is controlled by a computer program. The programme guides the machine as it cuts the material into the desired product.
The advantage of CNC over manual machining is increased accuracy, consistency, and efficiency, as the computer can perform tasks faster. It is also safer as you don't have the risk of a worker injuring themselves.
The disadvantages of CNC machinery are that is expensive. For example, a CNC lathe can cost upwards of £250,000! CNC metal milling with CNC milling machines can be just as expensive. Some CNC milling machines sell at £500,000!
Also, CNC milling machines and other CNC devices can malfunction and break down, which means costly repairs and business downtime.
What Is Metal Milling and Metal Turning?
The milling process, whether it's being completed with manual milling machines or CNC metal milling machines, is rather straightforward. It involves using a rotating cutting tool to remove material from a stationary item. Manual milling machines and CNC milling machines are typically used to create flat or complex shapes.
The milling process can also include a pocket milling machine. A pocket milling machine creates a shallow cavity or 'pocket' in a workpiece.
Metal turning is a process that involves rotating metal on a lathe while cutting tools to remove pieces of metal. This creates a cylindrical shape and is typically used to create cylindrical parts, like metal rods.
