What is a SPEED 21 Lathe?

A lathe is a machine tool used primarily for turning operations, that is, shaping materials by rotating the workpiece while a cutting tool removes the material. The SPEED 21 is a versatile model suitable for various applications, including cylindrical turning, conical turning, threading, drilling, and chamfering.

How to Use

The SPEED 21 lathe is used by clamping a piece of material (usually a metal cylinder) between the spindle and the tailstock. The workpiece is then rotated at high speed, while the cutting tool, mounted on a tool holder, is moved against the workpiece to remove material and create the desired shape. The 62 mm bar passage allows for machining large workpieces, while the 10 kW power output provides the necessary strength to machine resistant materials.

Materials Used

The SPEED 21 lathe is designed to work a wide range of materials, including:

• Steels : Structural, alloy and stainless steel, for resistant mechanical parts.
• Aluminum alloys : For components requiring lightness and corrosion resistance.
• Cast iron : Used for components that require high dimensional stability.
• Plastic materials : For prototypes and specific parts requiring electrical insulation or chemical resistance.

Main Industrial Sectors

The SPEED 21 lathe is used in various industrial sectors, including:

• General mechanical industry : Production of mechanical components such as shafts, bushings and flanges.
• Automotive industry : Turning of parts for engines, transmissions and suspension systems.
• Aerospace Industry : Production of structural components and engines.
• Energy Industry : Production of parts for turbines and power transmission systems.

Calculations and Formulas to Optimize Its Use

Optimization of the SPEED 21 lathe involves various calculations, including:

• Cutting speed ( VcV_c $V$ c ​) : Vc=π⋅D⋅nV_c = \pi \cdot D \cdot n $V$ c ​= $\pi$ $\cdot$ $D$ $\cdot$ $n$ , where DD $D$ is the diameter of the workpiece and nn $n$ is the rotational speed in revolutions per minute (RPM). This formula helps determine the optimal speed to avoid premature tool wear or workpiece damage.
• Feed per revolution ( ff $f$ ) : Indicates how much the tool moves in the longitudinal direction for each revolution of the workpiece.
• Depth of cut ( dd $d$ ) : Determines the amount of material removed per pass, influencing both tool life and the quality of the machined surface.

Similar Types of Lathes

The SPEED 21 lathe is a conventional lathe, but there are several other types of lathes, including:

• CNC Lathe : Numerically controlled for complex and high-precision operations.
• Parallel lathe : Similar to the SPEED 21, but available in various models with different capacities.
• Vertical lathe : Used for large, heavy workpieces, mounted vertically.

Alternatives to the SPEED 21 Lathe

• CNC turning centers : For high precision and geometric complexity production.
• Milling machines : For operations requiring both turning and milling.
• Multipurpose lathe : Combines turning and drilling, useful for operations that require multiple machining operations without moving the workpiece.

Why You Should Buy a Used SPEED 21 Lathe

used SPEED 21 lathe can be advantageous for several reasons:

• Sturdiness and Longevity : COMEV lathes, such as the SPEED 21 model, are built to last, with a rigid structure that maintains precision over time, even after years of use.
• Reduced Cost : Buying a used lathe represents a significant cost savings compared to a new one, without compromising the quality of the workmanship.
• Reliability : COMEV machines are known for their reliability and precision, so a well-maintained used model can still deliver high performance.
• Availability and Accessibility : A used lathe is often immediately available, reducing the wait time compared to purchasing a new model, which may have longer delivery times.

In conclusion, the COMEV SPEED 21 lathe is an equipment at a lower cost, while maintaining the ability to perform precise and efficient machining.
