The lathe CNC machine belongs to the category of machine tools.
Working of a CNC lathe
A lathe machine allows for the removal of material from an initially cylindrical workpiece. The machine works through a combination of workpiece rotation and the movement of the cutting tool. The workpiece is placed into the chuck and held by jaws. A motor enables the rotation of the mandrel. The cutting tool of the machine is positioned in a tool holder and tightened by screws. The tool holder itself is placed on a tool turret.
The tailstock allows for pointing operations, centring, drilling and boring in the end piece. Material is removed by the combination of the rotation of the workpiece and the movement of the cutting tool.
The CNC lathe works through an automated system. A program is first set up to determine the parameters of the operation. After the setup, the machine works automatically and allows for the choosing of the cutting tool and its move and deal with the spindle spins.
There are several factors that should be taken into account when purchasing a CNC lathe: - Number of turrets - Motorized or not Turrets - Number of tools on turret - CNC type
Advantages of a CNC lathe:
A CNC device can work for several tasks that must be accomplished in various areas. The main advantage of this machine is that it does different tasks all at once thanks to the CNC. The machine is fully automated and just needs to be set up and have the workpiece installed. Then the machine can complete the process without any loading. Furthermore, a CNC lathe is much cheaper than a “classic” lathe in term of labour cost; however, the machine itself is more expensive.
The machine is very polyvalent, and can work in many industries including metal cutting, textiles, automotive, aerospace, and more.
With Exapro you can filter searches for your CNC lathe based on:
Turning length in mm
Turning diameter in mm
Diameter above the bed in mm
Diameter above transversing slide in mm
Length between centres in mm
Centre height in mm
You can also narrow down the results by the location of the machine, year of the machine and the machine’s manufacturer.
