Blanchard grinding, a term synonymous with reliability efficiency, has revolutionized the way industries achieve flat, uniform surfaces on large workpieces. This process is known for its ability to quickly remove material and produce high-quality finishes.
What is Blanchard Grinding?
Blanchard grinding, also known as rotary surface grinding, is a method of removing material from one side of a large piece of metal or other material. The process involves a vertical spindle with grinding wheels mounted on a horizontal table. The table rotates, while the grinding wheel remains stationary, allowing for efficient and uniform removal of material.
How Does it Work?
The key to Blanchard grinding is its rotary action. The workpiece is placed on a rotating magnetic chuck, which holds it in place as the grinding wheel descends, and the grinding wheel can be adjusted to achieve different thicknesses and flatness requirements. This rotary motion ensures even material removal and produces a characteristic cross-hatch or swirl pattern on the surface.

Further, our capabilities allow us to deliver Double-Disc Grinding services that satisfy our client’s need for excellent dimensional control.
This article will discuss the differences between double-disc grinding and flat lapping and assess the best option for various applications.
What Is Double-Disc Grinding?
Double-Disc Grinding uses two opposing abrasive wheels to simultaneously grind both sides of a component. The wheels are side-mounted on a pair of spindles facing each other, and — because both sides of the workpiece are ground at the same time — fabricators achieve faster turnaround time. This method can also achieve tight-tolerance surface finishes, flatness, and parallelism in suitable applications.
This method is often classified into two machine types — horizontal and vertical double-disc grinder — based on how the grinding wheels are oriented and how parts cross through them. A double-disc grinder is horizontal if the wheels are paralleled to the floor and vertical if they are perpendicular.
The product of this grinding technique are flat plates with finishes to 16 Ra and parallel tolerances to .0005″, depending upon material type, size and stock removal.
Applications of Double-Disc Grinding
The most common applications for Double-Disc grinding are as follows:
Advantages and Disadvantages of Double-Disc Grinding
Double-Disc grinding ability is to extract equal parts of material from opposite sides of a workpiece that results in applying a reduced amount of internal stress to the materials. Furthermore, it enhances stability during machining operations, leading to higher accuracy and parallelism. Moreover, up to 50% of pre-machining costs are saved since this technique can achieve flatness tolerance faster than single-sided grinding.
On the other hand, Double-Disc Grinding fails to produce surface finishes as smooth as flat lapping. The latter grinding process is often used to correct irregularities or deterioration on the surface of metal parts.
What Is Flat Lapping?
Flat lapping is a mechanical sanding or polishing procedure where an abrasive is placed between two surfaces that are honed together. This process often results in a more accurate surface finish for elements and compounds like cast iron, ceramics, tungsten, plastics, carbon compounds, stainless steel, bronze, rubber, and silicon.
Applications of Flat Lapping
Flat lapping utilizes abrasive grains mixed with either oil- or water-based liquid vehicles to achieve a smooth surface. This method is typically used in the following applications:
Hard and brittle metals
Machining materials (e.g., glass)
Valve manufacturing
Polishing operations (automotive industries)
Advantages and Disadvantages of Flat Lapping
Due to the less complex machining process, flat lapping doesn’t require skilled laborers to complete the procedure, increasing its production rate. This technique also removes burrs on materials to achieve a high surface finish without generating heat.
However, flat lapping is generally slower than double-disc grinding, as only one side of the workpiece is furnished for each cycle. Additionally, it is not as pocket-friendly because it can only remove a minimal amount of stock on the material, and the surface finish needs to be uniform.
Why Choose Nifty Bar
Double-Disc Grinding offers more advantages to consumers than flat lapping. Not only is the former a more practical alternative, but fabricators can achieve a faster turnaround time than the latter.

Read on to learn more about how waterjet cutting works and its benefits.
What is Water Jet cutting and how does it work?
Waterjet cutting is a versatile and efficient way to cut various materials. It works by using a high-pressure jet of water, MIXED WITH GARNET, to cut through the material cleanly and precisely. This process can be used for both industrial and personal purposes, and it is an alternative to traditional methods such as sawing, drilling, or milling. Waterjet cutting is quick, easy, and accurate, making it a popular choice for many projects.
The benefits of using a waterjet cutter
There are many benefits of using a waterjet cutter over other methods, such as:
Water Jet cutting can cut through any material.
They can create very intricate cuts and designs.
Waterjet cutting is a very precise method of cutting.
There is no heat-affected zone (HAZ) when using a waterjet cutter. This means that the material being cut will not be damaged by heat.
Waterjet cutting is a clean method of cutting because there is no dust or debris created during the process.
Different types of materials Water Jet cutting Could be used
Waterjet cutting COould be used for a variety of other materials. These include, but are not limited to:
Metals such as aluminum, brass, and steel
Non-metallic materials such as glass, plastic, and stone
Composite materials such as carbon fiber and Kevlar
Each type of material has its unique properties that must be considered when choosing the best waterjet cutting method. For example, metals are strong and durable but can be difficult to cut through due to their hardness. Glass is fragile but can be cut with very high precision.
Waterjet cutting can also be used on composite materials, which are made up of multiple different types of material bonded together. This makes them extremely strong and resistant to damage. However, composite materials can be difficult to cut due to their complex structure.
When choosing a waterjet cutting method, it is crucial to consider the type of material that will be cut as well as the desired outcome. Waterjet cutting is a versatile technology that can be used on various materials. With proper planning and execution, waterjet cutting can produce precise, high-quality results.
Types of cuts using waterjet cutting
Waterjet cutting is a versatile process that can be used to cut various materials. The type of cut made with waterjet cutting depends on the material being cut and the application for which it will be used. Some common types of cuts made with waterjet cutting are:
Straight cuts: Straight cuts are the most basic type of cuts made with waterjet cutting. They are typically used for simple applications such as trimming or shaping edges.
Contour cuts: Contour cuts are more complex than straight cuts and are used when more precise shapes or patterns need to be cut into a material.
Kerf cuts: Kerf cuts are made by directing the jet of water at an angle so that it cuts a V-shaped groove into the material. They are often used for making decorative cuts or for joining two pieces of material together.
Pierce cuts: Pierce cuts are made by starting the cut at an edge of the material and then moving the jet of water in a circle to create a hole in the center of the material. They are typically used for applications such as creating holes for fasteners or making openings for pipes or ductwork.

Understanding the Benefits of Precision Saw Cutting
In precision saw cutting, a mechanized blade cuts through metal, wood, or plastic workpieces to create smaller components or pieces. Precision cutting is typically used to make components — such as pipes, tubes, and bars to the right dimensions. Unlike other cutting processes like laser cutting or waterjet cutting, saw cutting techniques use a sharp, hard blade to physically cut the material. These blades come in a variety of different styles, such as circular saws, cold saws, or band saws, to accommodate different material thicknesses and specifications. Precision sawing offers a wide range of benefits that make it essential in various fabrication projects.
Benefits of Precision Saw Cutting
Precision cutting offers several benefits for both high-volume and low-volume orders. Some of the most common benefits include:
Cost-Effectiveness. Precision sawing is a quick, simple process that doesn’t require specialized tooling and results in little to no material waste. Cutting yield loss is also typically covered in the price so there are no surprises.
Speed. Both manual and CNC sawing equipment can quickly cut through single workpieces for complex custom goods or large batches of pipes and bars. This ensures that products are ready for subsequent operations when you need them.
Outsourced services allow for lean manufacturing operations. By outsourcing your precision saw cutting services, you can save valuable plant floor space for your specialties rather than setting up bulky sawing equipment.
Precision. High-quality sawing processes can cut goods so they meet required specifications within tight tolerances and with minimal waste.
