Capstan vs. Turret Lathes: Perbedaan Utama Dijelaskan
Capstan dan turret lathes are semiautomatic lathes. Semiautomatic means machining is done automatically tetapi some other functions like changing of job/work piece dan setting of tools are done manually. Ini adalah modified version of engine lathe. Ini adalah contoh advancement of technology in manufacturing industry. Construction of turret/capstan lathes is similar to engine lathe tetapi difference is they have axially movable index able turret having hexagonal shape in place of tail stock on which multiple tools are fitted. These tools are capable in performing multiple tasks like turning, boring, thread cutting, drilling dan facing. By using these tools we can easily perform different type of operations on single work piece without changing of tool dan work piece. All these tools are mounted on hexagonal turret; turret is rotates after each operation. Turret lathe is used for mass production dan advantage of this lathe is a less skilled operator can perform work on it once all setup is done properly. These types of lathes can be used for machining large work piece also. These lathes are relatively costlier than engine lathe because of their complex construction. Using these lathes a single type of job can be easily repetitive manufacture with less effort dan time or we can say that both lathes are used for mass production.
Both turret dan capstan lathes are similar in construction, operation dan in some applications also but major differences between them are as follow:
| Turret lathe | Capstan lathe |
| 1 | In turret lathe main turret is directly installed on saddle dan saddle is move along entire length of lathe bed. | Capstan lathe is ram type turret lathe dan movement of ram is limited. |
| 2 | In turret lathe turret tool head is directly mounted on saddle dan they appear like a single unit. | Turret head is mounted on a slide called as ram which is mounted on saddle in case of capstan lathes. |
| 3 | In turret lathe saddle is moved for providing feed to tool. | But in case of capstan lathe saddle is fixed at a point but ram is moved. |
| 4 | Saddle is move along entire length so it is used to machining of large work pieces. | The short strokes of ram have some limitations so this lathe is used to machining of small work piece only. |
| 5 | It has slower operation because of heavy weight of all components. | It has fast working operations because lighter in construction. |
| 6 | In turret lathe limit dogs are used to control movement of tool. | In case of capstan lathe feed stop screws are provided at rear side of turret for controlling tool movement. |
| 7 | It is used to machine large work piece so large depth of cut dan feed is provided for machining. | Relatively less feed dan depth of cut are provided for machining because used for small work pieces. |
| 8 | In turret lathes external threads are generally cut by single point atau multipoint chasing tool which is installed on front slide dan moved by short lead screw dan swing type half nut. | But in case of capstan lathe external threads are cut using self opening die which is mounted on one face of turret. |
| 9 | Turret lathe is mostly single spindle dan horizontal type lathe but may be vertical dan multi spindle type in some cases. | But capstan lathe is usually single spindle dan horizontal axis type only. |
| 10 | In turret lathes power operated jaw chucks are used to hold work piece. | In case of capstan lathe hand operated collect chucks are used for holing work piece. |
These are all major difference between capstan dan turret lathe. Jika ada pertanyaan mengenai artikel ini, tanyakan melalui komentar. Jika suka artikel ini, jangan lupa untuk membagikannya di jaringan sosial. Langganan situs web kami untuk artikel informatif lainnya. Terima kasih telah membaca.
