What Is 5-Axis Machining?

5-Axis machining , a method employed in CNC (Computer Numerical Control), operates by moving a part or cutting tool along five different axes simultaneously. This process allows for efficient machining of complex parts, reducing human error, and shortening lead times.

The cutting tool can approach the workpiece from any direction, offering flexibility and precision. This versatility makes 5-axis machining integral to industries requiring intricate detailing, such as aerospace.

History of 5-Axis Machining

The concept of 5-axis machining originated during the mid-20th century, when machine configurations evolved to increase efficiency and precision.

A 5-axis CNC machine works by simultaneously moving a part or cutting tool along five different axes. This enables the machining of complex parts in a single setup, reducing human error, and shortening lead times. The cutting tool can approach the workpiece from any direction, resulting in a highly precise finished product.

Components of a 5-Axis Machine

A 5-axis machine comprises several key components: the controller, drive system, feedback system, axis table, and spindle. The controller orchestrates the system, while the drive and feedback systems manage movement. The rotary axis table holds the workpiece, and the spindle manipulates the cutting tool.

5-Axis vs. 3-Axis CNC

5-axis CNC machines outperform their 3-axis counterparts in terms of versatility and precision. Unlike 3-axis machines, which limit movement to three directions, 5-axis machines maneuver along five different axes, enabling them to efficiently produce complex and intricate parts with shorter lead times and higher-quality surface finish.

How much does a 5-axis CNC machine cost?

The cost of a 5-axis CNC machine varies widely based on its capabilities and specifications. Factors such as size, complexity, and brand significantly influence the price. However, despite the higher initial investment compared to 3-axis machines, 5-axis CNC machines often provide greater value in the long run due to their versatility, precision, and efficiency.

What is Blanchard Grinding?

Blanchard grinding is a type of rotary surface grinding. The Blanchard grinder can remove large amounts of material from a workpiece, making it ideal for quickly finishing surfaces. This efficient method gets its name from the company that originally developed and patented the machine design, the Blanchard Machine Company. It is best suited for single-sided or double-sided grinding of parts with flat surfaces.

How does Blanchard grinding work?

The grinding stones are mounted on a vertical spindle and creates a cross-hatch pattern while the part is rotated on a magnetic chuck. This grinding method is used to remove stock from one side of a part. Blanchard grinding can produce a very fine finish with little or no coarseness on the surface of the part.

What are the benefits of Blanchard grinding?

The main advantages of Blanchard grinding are high material removal rates and fast cycle times. It is also one of the most cost-effective types of precision grinding.

Are there any downsides to Blanchard grinding?

The main disadvantage is thermal damage to the workpiece, especially if not the work is not performed correctly or is rushed. When it comes to Blanchard grinding, you want to make sure you entrust your work to the right people.

What can you Blanchard grind?

Blanchard grinding can be used on a variety of materials, including ferrous metals, non-ferrous metals and plastics. Examples of pieces that use Blanchard grinding are

Tool and die
Large stampings
Castings
And plate stock

Can you Blanchard grind aluminum?

Aluminum can be Blanchard ground, but it requires a fixture to be held in place on the magnetic chuck. For this reason, Blanchard grinding is not typically used on aluminum unless it is absolutely necessary.

Can you Blanchard grind stainless steel?

When grinding stainless steel, the metal workers must be careful not to overheat the metal, as this can cause damage to the material. Grinding stainless steel with a Blanchard grinder can provide a high-quality surface finish with minimal material removal. Certain grades of stainless steel will require fixturing similar to aluminum because of its lack of magnetism.

How accurate is Blanchard grinding?

Blanchard grinding is well suited for large-scale surface grinding, as well as for small parts that need to be held in place with a chuck during grinding. And, it can achieve very high levels of precision and accuracy, achieving tolerances of plus or minus 0.001 inches (0.0254 mm).

However, the process is not without its challenges. In particular, the large grinding wheels used in Blanchard grinding can cause vibration and noise, making the process less than ideal for some applications. Nevertheless, when used properly, Blanchard grinding can be an extremely effective material removal technique.

What tolerance of flatness can you achieve with Blanchard grinding?

Typical flatness easily achievable on a Blanchard grinder would be around ±.001 (0.0254mm) or better.

Who invented the Blanchard grinder?

In 1909, Winslow Blanchard of Blanchard Machine Company in Cambridge, Massechussettes, assigned one of his inventors to concoct the Blanchard Grinder. Henry K. Spencer, who had just graduated from MIT, developed the vertical rotary surface grinder within six months.

The original machine started off small in diameter, but as attention grew, grinding machines became more in demand, evolving over the past 100 years. Now, Blanchard grinders are much larger than they used to be, but still deliver that smooth surface finish many machinists and companies were after in 1909.

What is the difference between Blanchard and surface/cylindrical grinding?

If you are well versed in the industry, you will know that there are many different types of grinding methods. Some of the most popular are rotary Blanchard grinding and surface/cylindrical grinding. So what are the differences in methods of grinding?

Blanchard Grinding

As we have established, Blanchard Grinding is for large flat surface areas. Blanchard Grinding is considered to have more aesthetic appeal as well, leaving a surface finish of 63 Ra or less.

Surface/Cylindrical Grinding

Surface/Cylindrical grinding is geared towards high precision tolerance and finish work. It can achieve a surface finish of 8 Ra or less, and tolerances of ±.XXXX or better.

Cylindrical grinding — used for round objects
Surface grinding — an abrasive wheel rotates at a high speed to grind a flat surface.

How much does Blanchard Grinding cost?

The cost of Blanchard Grinding typically depends on the material being ground, surface area size, and material thickness. If you are looking for a precise quote on a particular project, we would be happy to give you an estimate. So contact us today for your free quote!
