Advantages of Precision Machining
 
01/

Low Error: By using CNC machines, once the correct specifications are keyed in, the automated precision machining process takes over. The chances for error is extremely low as compared to human machining. When you outsource this work, you avoid the need to recruit and hire the highly skilled staff needed to run these machines.

02/

Less Material Waste: As the core concept of precision machining is subtraction, there is enormous potential for material waste start to finish on a single product. CNC precision machining helps reduce material costs due to wastage human error.

03/

Consistent Product Quality: Precision machining via CNC machines leads to consistent output time after time. Consistently producing quality product runs leads to customer confidence and enhances your brand’s awareness.

04/

Improved Workflow: When looking at how to manage opportunity costs, it’s key that engineers’ time and skills are spent on actual product development and not tiny design changes.

05/

Reduced Turnaround Time: The opportunity exists to improve your existing factory workflow (either with in-house precision machines if you can afford the machine investment and the skilled labor to operate it), or, by using contract machining services.

06/

Faster Production Cycles: Being able to offer your product to market faster gives you an edge over facilities that are still using older methodologies. You’re also likely to be more flexible with changes due to industry regulations or customer requests.

 

Application of Precision Machining
 

Aerospace industry

Aircraft turbines, engine blocks, landing gear, and structural airframe components demand ultra precision to balance weight, strength, and safety. Tight tolerances, exotic materials like titanium, and complex 3D forms characterize aerospace parts.

Automotive

Mass production lines for automotive rely on precision machined tooling and molds along with components like gears, shafts, cylinders, valves, and suspension parts.

Medical

Surgical tooling, dental drill guides, joint replacement implants, and other medical devices call for biocompatible metals and plastics shaped into tiny sub-millimeter scales.

Optics

Precision machining creates mirrors, lenses, prisms, and other optical components by contouring extremely smooth surfaces within micron tolerances for light transmission control.

Electronics

From semiconductors to consumer devices, electronics packaging entails tiny, intricate CNC machined enclosures, connectors, and micro-scale features.

Robotics

Articulated robotic arms, joints, and end effectors used in high-mix assembly, materials handling, welding, and processing rely on tight clearance machined aluminum and steel components.

 

Types of Precision Machining
 

CNC Machining: Computer numerical control (CNC) machining is an umbrella term for manufacturing processes like milling, turning, grinding, and drilling that use programmed commands to direct machine tools. Common CNC machines include machining centers, lathes, grinders, and CNC mills.

 

Multi-Axis CNC Machining: Multi-axis CNC machining refers to machines with four or more programmable axes. This enhances flexibility to shape complex 3D contours and curved geometries in a single setup. For example, 5-axis milling manipulates parts along the traditional X, Y, and Z linear axes while simultaneously tilting and rotating.

 

Swiss Machining: Swiss Machining (also called Swiss turning) is a specialty CNC method using automatic lathes. Swiss CNC lathes have a moving headstock and guide bush that enables centralized workpiece support while cutting across multiple axes.

 

CNC Turning: On a CNC lathe, the workpiece rotates against a non-moving cutting tool, which machines diameters, contours, grooves, and faces. CNC turning handles both straight and tapered diameters plus eccentric contours controlled via CAM programming.

 

CNC Drilling: CNC machining centers can accurately drill holes with extreme precision unattainable manually. Hole making operations, from simply spotting locations to drilling, countersinking, boring, tapping, and reaming are programmable.

 

Electrical Discharge Machining: EDM machining applies electrical spark erosion to vaporize conductive materials vs traditional cutting or grinding. No force is exerted, enabling intricate contours even in hardened materials that are too difficult to machine by conventional methods.

 

 

Custom Precision Machining

Parts may not exist elsewhere for a number of reasons. In many cases, custom machining is needed when engineers are creating a novel production item whose individual components cannot be bought from a supplier — Or at least not at a reasonable price.

 

Those components may be something simple, like a gear or button in a nonstandard size or material, or they may be completely new inventions.Alternatively, custom machining may be required for an entirely commonplace part which happens to have a special requirement, such as a custom adapter, extra feature or textual engraving.

 

Whether it’s metal machining (of aluminum, bronze, brass, stainless steel, etc.) or plastic machining — Has all the usual benefits and capabilities of on-demand CNC. Quality parts can be made very quickly from their digital files, even in an emergency, since setup times are short and there is rarely a minimum order quantity.

Precautions for Use Precision Machining

 

 

First of all, the influence of external factors on the machining accuracy must be excluded. For example, the horizontal tilt of a machine tool may not be abnormal for a short period. However, when running for a long time, the machine bed will be slightly deformed.

 

Generally, the precision machining of complex parts will use a fixture to clamp the workpiece. The positioning, clamping, and precision here are all guaranteed by the fixture, so the fixture must have certain rationality. Satisfy the stability and reliability of workpiece positioning during use. There is enough bearing capacity or clamping force to ensure the machining process of the workpiece on the fixture. Satisfy the reliability of the repeated positioning of the fixture when the fixture is adjusted or replaced.

 

Steps in the Precision Machining Process

Design: Before partnering with a manufacturer, it is important to have your product design ready. Using Computer-Aided Design (CAD) software, 2D and 3D models of your product are created. This gives your manufacturer all of the design information needed to get started on production right away.

 

CNC Programming: The CAD drawings are used by a CNC programmer to enter instructions into the Computer-Aided Manufacturing (CAM) software. The CAM software then converts the instructions into machine-readable code.

 

Machining: Once your designs are created and sent to your manufacturer, the machine is loaded with the program, and machining can begin. The machinist performs the machine setup. This includes loading the tools, touching off the tools, ensuring the parameters on the machine are correct, loading the CNC program, and loading the part into the machine.

 

Finishing and Secondary Processes: Many times, after CNC machining, parts don’t need finishing or secondary processing, however, some parts may need plating, polishing, or grinding in order to function properly and meet desired specifications.

 

 

FAQ

Q: What is the process of precision machining?

A: Precision machining is a process that removes excess, raw material from a work-piece, while holding close tolerance finishes, to create a finished product.

Q: What is the order of machining operations?

A: The correct sequence of machining operations to be performed to finish a large diameter through-hole is drilling, boring, reaming. Drilling: Drilling is an operation to produce a cylindrical hole in a workpiece. The tool used in called “drill bit”.

Q: What is precision processing?

A: Precise processing, also known as precision machining, is machining to obtain more dimensional accuracy and surface roughness than can be obtained with general lathes and presses.

Q: What is the process of precision engineering?

A: This involves the use of advanced technology and specialised equipment to achieve a high degree of accuracy in the manufacturing process.

Q: What is the 3 2 1 method of machining?

A: The 3-2-1 method is a work-holding principle where three pins are located on the 1st principle plane, i.e., either XY, YZ, ZX. And two pins are located on the 2nd plane perpendicular to the 1st plane, and at last, one pin on the plane is mutually perpendicular to the 1st and 2nd planes.

Q: What are the basics of precision machining?

A: Precision machining is a process to produce accurate components with high tolerances and excellent surface quality by removing materials from a workpiece.

Q: What is the tolerance for precision machining?

A: The standard prototype and production machining tolerance is +/- 0.005 in. (0.13mm). This means any part feature's location, width, length, thickness, or diameter will not deviate by more than this amount from nominal.
