THE MAIN PARTS OF CNC TURNING MACHINE

THE MAIN PARTS OF CNC TURNING MACHINE.
  • Headstock
  • Cnc Bed
  • Cnc Chuck & Jaws
  • Tailstock
  • Tailstock Quill
  • Foot Switch Or Foot Pedals
  • Cnc Control Panel
  • Tool Turret.

HEADSTOCK
Headstock of a cnc lathe machine have the main motor of cnc Turning machine which spindle. Chuck is mounted on this main spindle. the headstock covers are removed, so you can see the Main drive (Main Motor).

CNC TURNING BED
The Bed Is Designed To Support And Align X-z Axes And Cutting Tool Can Be Cut The Component On The Machine. Bed Is Designed In Two Ways: They Either Lie Flat Or At The Slant.
   Most CNC Turning Have A Slant Bed
Design, Providing The Operator Easy Access For Loading And Unloading Parts And Tools. It Also Allow The Chips And Coolent To Fall Away From The Cutting Area To The Bottom Of The Chip Conveyor.

CNC CHUCK AND JAWS
  • The Chuck Is Mounted On The Spindle And Is Equipped With The Set Of Jaws To Grips The Component Which Are To Be Machined. Chuck Itself Has Many Parts. Jaws Are Mounted On The Chuck To Grip The Part,
Types of CNC Chuck's 
  • The Chuck Can Be Design As A2 Jaws, 3 Jaws, 4 Jaws ,Collet Jaws.
  • The Jaws Are Either Hardered (Hard Jaws) Or Mild Steel (Soft Jaws) Are Selected Depending On The Operation Holding Requirements. The Hard And Soft Jaws Are Available In Various Standard Design.

TAILSTOCK
The Tailstock Is Used To Support Workpieces That Lack Rigidity Such As Long Shafts, the Tailstock Can Be Designed To Operate Either Manually Or By Cnc Program Commands. The Tailstock Basically Supports One End Of The Workpiece With The Center. The Most Common Is The Live Center, which Rotates On A Bearing Pack To Eliminate Friction.

Tailstock Quill
Actually you move the whole tailstock forward or reverse, but in that way it is not used to grip the part, but tailstock is travelled to a point near the component and then it is set there, after that you actuate the tailstock quill which travel either with hydraulic pressure or pneumatic pressure to grip the component.

FOOT SWITCHES OR FOOT PADELS
Foot switches are used to actual the chuck and tailstock quill. Through these pedals cnc machinist's open and close the chuck to grip the component, the same way tailstock quill is taken to forward position or reversed through theses pedals.

CNC CONTROL PANEL
The CRT (Cathode Ray Tube) is Also On The Control Panel. The Crt Display Allows The Operator Easy Visual Access To Cnc Program And Machine Information. On The Screen Of The Cnc Control, The Operator Can View The Cnc Program, active Codes, Tool And Workpiece Offsets, machine Positions, Message alarm,  Error, Spindle Rpm Etc Etc There Are Many Types Of Cnc Controller Used In Industries. 


TOOL TURRET
There are 2 types of tool holding devices on chc turning machine,
  • Turret tooling
  • Gang tooling
Turret tooling -The function of turret head is to hold various types of tools and utilize them when needed for any specific machining operation. The turret rotates and locates a tool according to machine coordinates.

GANG T0OLING
Gang Tooling Involves Setting Up A Row Of Tools Inside The Lathe On A Cross-slide, Which Is Similar To The Table on a milling machine. 
       "Generally, Gang Tooling Is More Useful On Small Lathes Cutting Small Parts, Using A Limited Number Of Tools"Gang Tooling Works Well In These Situations Because The Cycle Time Can Be Minimized Since The Turret Index Time Is Eliminated. Also, Tool Change-over Time Can Be Reduced To Nearly Zero Since The Tool Plates Can Be Switched Out Quickly For Each Job"
