CNC Metal Materials
We know every project has its unique requirements and properties, we can offer the best metal & alloy materials and machining solutions for your project.
Alloy steel contains trace amounts of one or more alloying elements (other than carbon), such as manganese, silicon, nickel, titanium, copper, chromium, and aluminum. Alloying provides it with unique qualities not present in standard carbon steel. Due to its low cost, wide availability, ease of processing, and superior mechanical rates, alloy steel is ideal for industrial applications. In general, alloy steels are more malleable to heat and mechanical treatment than carbon steels.
LEADRP offers a complete Alloy Steel CNC machining service and can produce custom Alloy Steel parts in various shapes and grades, including 4130, 4140, 4340, and more.
Mild steel is a type of carbon steel with a low amount of carbon. It is also known as “low carbon steel.” Low carbon means it has very little carbon and other alloying elements to block dislocations in its crystal structure, resulting in less tensile strength than high carbon and alloy steels. Mild steel has good weldability and machinability, making it a popular choice for consumer products.
LEADRP offers a complete Mild Steel CNC machining service and can produce custom Mild Steel parts in a variety of shapes and grades, including Hot and Cold Rolled, Commercial Quality, Galvanized, 1018, 1020, 1026, 1020/1026, CR 1045, HR 1045, 12L14, CR 1215 and more.
Tool steel is a type of carbon alloy steel. It is frequently used to create, modify, or repair hand tools and machine dies. Tool steel is notable for its hardness, abrasion, and deformation resistance. Because steel can retain a cutting edge at extremely high temperatures, it is frequently used to shape other materials via cutting, pressing, coining, or extruding. Because of their abrasion resistance, they are commonly used in the production of injection molds. Tool steel is widely used in dies (stamping or extrusion), cutting, mold production, and impact applications such as hammers (personal or industrial).
LEADRP offers a complete Tool Steel CNC machining service and can produce custom Tool Steel parts in various shapes and grades, including A2, D2 and O1, and more.
Stainless steel is a steel alloy that is more corrosion resistant than carbon/alloy steel. Stainless steel is an iron alloy that contains at least 10.5 percent chromium. The presence of chromium results in forming a thin chromium oxide film on the surface of the steel, known as a passivation layer. This layer prevents corrosion on the steel surface; the higher the Chromium concentration in the steel, the more excellent the corrosion resistance. Stainless steel is an ideal material for food handling/processing, medical instruments, hardware, appliances, and structural/architectural products.
LEADRP offers a complete Stainless Steel CNC machining service and can produce custom Stainless Steel parts in various shapes and grades, including 17-4, 303, 304, 316, 416, 440C, and more.
Copper alloys are one of the most versatile metals, and they have beneficial properties like corrosion resistance, high thermal conductivity, and very high electrical conductivity. Copper alloys are excellent for different industries such as electrical, construction, transport, and consumer goods. The final product made from copper includes architectural parts, coinage, condenser/heat exchangers, plumbing, radiator cores, musical instruments, locks, fasteners, hinges, ammunition components, and electrical connectors.
LEADRP offers a complete Copper CNC machining service and can produce custom Copper parts in a variety of shapes and grades, including Copper C110 and C101.
Brass is a mixture of copper and zinc. Small amounts of zinc elements are frequently added to improve specific properties. Depending on the part of zinc added to the alloy, the color of brass can range from red to yellow. Alloying can increase strength, hardness, electrical and thermal conductivity, corrosion resistance, and color. Brass is also germicidal, which means it can kill microorganisms when they contact it.
Brass is used in various applications and products, including decorative items, architectural parts, condenser/heat exchangers, plumbing, radiator cores, musical instruments, locks, fasteners, hinges, ammunition components, and electrical connectors.
LEADRP offers a complete Brass CNC machining service and can produce custom Brass parts in various shapes and grades, including Brass C260 and C360.
Aluminum is a silver-colored, low-density metal used in various commercial applications. Under most conditions, unalloyed aluminum is ductile, has moderate strength, and is highly corrosion-resistant. Appropriate alloying elements (Cu, Mg, Mn, Si, etc.) and subsequent heat/work treatments can significantly strengthen aluminum. Because of its low density and corrosion resistance, aluminum is widely used in aerospace, transportation, architecture, food, and chemical handling (cookware, pressure vessels, etc.).
LEADRP offers a complete Aluminum CNC machining service and can produce custom Aluminum parts in various shapes and grades, including 1100, 2011, 2024, 3003, 4017, 5052, 6061, 6063, and 7075.
Titanium alloys are alloys composed of titanium and other chemical elements. Titanium alloys are light in weight, have incredibly high tensile strength and toughness, are extremely corrosion resistant, and withstand extreme temperatures.
Titanium alloys are widely used in military applications, aircraft, spacecraft, bicycles, medical devices, jewelry, high-stress components such as connecting rods on high-end sports cars, and some premium sports equipment and consumer electronics.
LEADRP offers a complete Titanium CNC machining service and can produce custom Titanium parts in various shapes and grades, including Titanium Grade 1, Titanium Grade 2, and Titanium Grade 5.
There are many other metal and alloy materials for different applications. Whether it’s on our material list or not, we could source them from a certified supplier for your project.
CNC Machined Parts
Overview of CNC Machining
The CNC machining process, use computerized controls to operate and manipulate machine tools that cut and shape stock material. Furthermore, the process follows the same basic production stages as all CNC machining processes, which include:
- Creating a CAD model
- Creating a CNC program from the CAD model
- Configuring the CNC machine
- Carrying out the machining operation
The CNC machining process starts with the design of a 2D or 3D CAD part. The completed design is then exported to a CNC-compatible file format and converted by CAM software into a CNC machine program, which instructings the machine’s actions and tooling movements across the workpiece. Before running the CNC program, the operator must first prepare the CNC machine by attaching the workpiece to the machine’s work surface (worktable) or work holding device (e.g., vise) and attaching the milling or turning tools to the machine. Depending on the specifications and requirements of the machining process, the CNC machine will use different cutting tools such as mills and drills. When the machine is ready, the operator starts the program via the machine interface, instructing the machine to perform the machining operations.
Benefits of CNC Machining
CNC machining centers are quick and precise, allowing for the efficient production of complex and specialized products. CNC machining has lots of advantages, including:
Cost Savings
Every business seeks ways to reduce costs while maintaining quality. CNC Machining enables the efficient production of complex and specialized products because they work faster and more accurately.
Safety
When a CNC machine is running, there is no bending or crouching required to operate the machines. So, there should be fewer workplace accidents and less fatigue, which reduces the risk of human error in the machining process significantly. And also, the safety and ergonomic conditions for workers are greatly improved.
Efficiency
CNC machines can operate continuously with little downtime. A fully-automated CNC machining facility can keep running without interruption 24 hours a day, seven days a week.
Versatility
One of the most significant advantages of CNC machining is its versatility. CNC machining enables manufacturers to cut or shape a wide range of materials while maintaining quality and efficiency.
CNC milling are ideal for a wide range of complex, high-quality production runs of all sizes. CNC machines will also save you a lot of time and money because of their operational efficiency and lower labor costs.
