  • Turning: Turning is used to machine cylindrical workpieces and can perform finishing operations such as facing, chamfering or grooving to achieve the desired surface finish and dimensional accuracy. Our turning accuracy can reach +/- 0.02mm.
  • Drilling: Drilling is the process of drilling a hole in a workpiece using a rotary drill. Our drilling accuracy can reach +/- 0.02mm.
  • Grinding: Grinding processes can be used to achieve precise dimensions, tight tolerances and excellent surface finish, for example for precision mold inserts. Our precision grinding machines have a machining accuracy of up to +/- 0.002mm.

What High Volume Machining Equipments Do We Offer?

In high volume machining, a variety of machinery and equipment include CNC machining centers, lathes, milling machines, grinding machines, and specialized tools such as drills, cutters, and inserts. These machines are equipped with advanced features like multiple axes, automatic tool changers, and high-speed spindles to optimize productivity and precision.

Each machine and tool is selected based on the specific requirements of the part, desired production volume, and the capabilities of the machining facility. The continuous advancements in machining technology contribute to increased productivity, precision, and efficiency in high volume manufacturing processes.

CNC Machining Centers: They are equipped with multiple axes (typically 3 to 5 axes) and can move the cutting tool in different directions simultaneously. CNC machining centers can perform milling, drilling, tapping, and sometimes turning operations in a single setup, making them highly efficient for high volume production.

CNC Lathes: Designed specifically for turning operations. They rotate the workpiece while a cutting tool removes material to create cylindrical shapes. CNC lathes often have multiple axes, allowing for complex machining operations, such as turning, facing, threading, and grooving. They can be used to produce high volumes of precision parts with excellent surface finishes.

CNC Milling Machines: Used for precision milling operations. They have a rotating cutting tool that removes material from the workpiece to create various features, such as slots, pockets, contours, and complex 3D shapes. CNC milling machines can be equipped with horizontal or vertical spindles and may have multiple axes to enable simultaneous cutting in multiple directions.

Grinding Machines: Used to achieve fine surface finishes and precise dimensions through abrasive material removal. They utilize grinding wheels or abrasive belts to remove material from the workpiece. Different types of grinding machines, such as surface grinders, cylindrical grinders, and centerless grinders, are used depending on the specific requirements of the part.

Drilling Machines: Used to create holes in the workpiece. They employ rotating drill bits to remove material and generate holes of various diameters and depths. CNC drilling machines can automate the drilling process, allowing for precise hole placement and consistent results.

Cutting Tools and Inserts: A variety of cutting tools and inserts include end mills, drills, taps, reamers, inserts, and more. Cutting tools and inserts are selected based on factors such as the material being machined, required surface finish, and specific machining operation. They are designed to provide high cutting speeds, long tool life, and efficient chip evacuation.

Measurement and Inspection Equipment: High volume machining often involves the use of measurement and inspection equipment to ensure dimensional accuracy and quality control. This may include calipers, micrometers, height gauges, coordinate measuring machines (CMMs), and vision systems. These tools are used to verify part dimensions, tolerances, and surface finishes.
