What are vertical turret lathes?
Vertical turret lathes have the workpiece held vertically, which allows the headstock to sit on the floor and the faceplate to become a horizontal rotating table, analogous to a huge potter’s wheel. This is useful for the handling of very large, heavy, short workpieces.
What is the VTL machine?
Vertical turning lathes (VTL) are machines that orient the spindle in the vertical plane in a fixed position. The workpiece then spins, moving up and down to put it in line with the cutting head. These machines are less complex than horizontal lathes.
What is turret lathe and its types?
Based on Orientation, Turrets Lathes Are Divided into Two Types: Horizontal Turret Lathe:- In the horizontal turret lathe, the orientation of the hexagonal turret and the workpiece is horizontal. Vertical Turret Lathe:- In the vertical turret lathe, hexagonal turret and workpiece have a vertical orientation.
How are turret lathe classified?
As to size, turret lathes are classified as small (bar capacity d = 25 mm, chucking capacity D = 320 mm), medium (d = 80 mm, D = 500 mm) and large (d = 160 mm, D = 800 mm). According to the turret arrangement, turret lathes are classified as those having turrets with a horizontal (Fig. 32.2 a), vertical (Fig.
How is the size of a turret lathe specified?
Normally the size of a CNC lathe is specified by the Chuck size for example 6 inches,8 inches ,12 inches which denotes maximum diameter of component that can be held ,in case conventional lathe it is denotes by maximum swing over bed that is maximum diameter that can turned ,another specifications is admit between …
Which lathe was developed to turn particularly large or heavy workpieces?
Capstan and turret lathes are improvements in engine lathes that can be used for high volume production and for large jobs.
What is the difference between engine lathe and turret lathe?
Turret movement can be controlled automatically. engine lathe tool movement can control manually. In capstan and turret lathe number of speeds is more in engine lathe number of speeds is less. Capstan and turret lathe is suitable for mass production while engine lathe is not suitable for that.
What is the difference between capstan and turret lathe?
In turret lathe the main turret is directly installed on the saddle and the saddle is move along the entire length of the lathe bed. Capstan lathe is ram type turret lathe and the movement of the ram is limited. In turret lathe the turret tool head is directly mounted on the saddle and they appear like a single unit.
Why HMC are better than VMC?
HMCs increase efficiency, reduce operating costs, grow the business and increase profitability. On a VMC, parts are moved from fixture to fixture seven to nine times; on a HMC this goes down to three moves per part. By regaining 30 percent of processing time, profitability is greatly increased.
