But at Gmetal, you should trust that our staff is working with you to help you produce high-quality parts on schedule.

To us you are more than an order, we will work with you so you get quality work on time.

Benefits of CNC Machining

CNC machining has many benefits. Once the toolpath is created and the machine is programmed, it can run the part 1 time or 100,000 times. CNC machines are designed for precision manufacturing and repeatability, making them cost-effective and highly scalable. CNC machines can also machine a variety of materials, from basic aluminum and steel to more exotic materials like titanium, making them ideal machines for almost any job. That’s why rapid CNC machining is one of the most popular methods for manufacturing plastic and metal parts.

CNC machining is well suited to meet a range of your product development needs. Here are some of the advantages of precision machining:

  • Wide range of materials
  • Economical and fast turnaround
  • Ability to maintain tight tolerances
  • Scalability and repeatability
  • Capacity scalable from 1 to 100,000
  • Parts machined directly from 3D CAD models
  • Standard delivery time is 1-2 weeks depending on order
  • Shorter lead times (2-5 working days) per open capacity

  • Grade 2 (Ti-CP): Commercially pure titanium with good weldability and moderate strength.

The advantages of Titanum:

  • High Strength-to-Weight Ratio: Titanium is renowned for its exceptional strength-to-weight ratio, meaning it is incredibly strong while being lightweight.
  • Corrosion Resistance: Titanium exhibits remarkable corrosion resistance, even in aggressive environments such as seawater and chemical environments. It forms a protective oxide layer on its surface, which provides excellent resistance to corrosion, erosion, and oxidation.
  • Biocompatibility: Titanium is biocompatible, meaning it is non-toxic and does not react with the human body. It is commonly used in medical and dental implants, as well as surgical instruments. Its biocompatibility and corrosion resistance allow for long-term use within the human body.
  • Excellent Fatigue Strength: Titanium has exceptional fatigue strength, allowing it to withstand repeated loading and stress cycles without failure. This property is particularly important in applications where components are subject to cyclic loads, such as aerospace structures and automotive suspension systems.
  • Non-Magnetic: Titanium is non-magnetic, making it useful in applications where magnetic interference must be minimized or eliminated, such as in certain medical devices or sensitive electronic equipment.
  • Longevity and Low Maintenance: Titanium’s resistance to corrosion, fatigue, and wear translates to long-lasting performance and reduced maintenance requirements in many applications, leading to cost savings over time.

The types of Copper Gmetal provide for CNC Mchining:

Different Types of CNC Machines

CNC Turning
CNC Turning

CNC turning is a specialized form of precision machining in which a tool removes material through contact with a rotating workpiece. The machine’s movements are controlled by computer instructions with extremely high precision and repeatability.
Turning differs from CNC milling, in which the cutting tool rotates and is pointed at a usually stationary workpiece from multiple angles. Because CNC turning involves rotating the workpiece in a chuck, it is often used to create circular or tubular shapes, resulting in a more precise rounded surface than CNC milling or other processes.
CNC lathes use cutting tools that are mounted on a turret. The component is programmed to perform certain movements and remove material from the raw material until the desired 3D model is formed.

CNC Milling
CNC Milling

CNC milling is just one of the CNC machining processes available. Milling is a specialized form of precision CNC machining. Milling uses a tool moved into the workpiece at an angle to remove material. The movement of the tool is controlled by computer instructions with extremely high precision and repeatability.

CNC Bending
CNC Bending

The CNC bending process is more flexible because negative and positive angles, size and sequence are all programmable. Gmetal CNC Bending processes different workpieces in one pass and in large series. Automatic tool changing system eliminates manual setup between batches. Gmetal CNC Bending can be integrated into other processes such as spot welding and riveting.
