Jenis Mesin Gerinda: Tinjauan Komprehensif

Hari ini kita akan membahas tentang main type of grinding machine. Grinding adalah another type of machining process which is used to for finishing purpose. This process is used as secondary machining process because it is always done after primary machining on other machine tool like lathe, milling machine etc. Kami telah membahas tentang grinding process in last article. Jika Anda belum membaca artikel itu, silakan baca terlebih dahulu.

Grinding adalah simple process in which very small size of chips are remove from work piece by rubbing action of abrasive material. But at different condition according to working environment, berbagai jenis grinding machines is used.

Jenis Mesin Gerinda:

The conventional Grinding machine tools are classified in mainly four categories which are as follow:

1. Surface Grinding machine
2. Cylindrical Grinding machine
3. Internal Grinding machine
4. Special types of grinding machines

1. Surface Grinding machine:

As the name suggest surface grinding machine is used to machine outer surfaces mainly flat and horizontal surfaces but using formed grinding wheel this type of grinding machine is also capable to machine counter surfaces. Surface grinding machines are further classified according to position of spindle and working table which are as follows:

1. Reciprocating table with horizontal spindle
2. Reciprocating table with vertical spindle
3. Rotary table with horizontal spindle
4. Rotary table with vertical spindle

2. Cylindrical Grinding machine:

It is used to machine cylindrical work pieces only. It is capable to machine only outer surfaces of cylindrical objects but can be able to machine any cylindrical profile such as tapered, straight and stepped profiles. This machine also further classified according to portion of work piece and grinding wheel which is as follow:

1. Centreless cylindrical surface grinding machine
2. Universal cylindrical surface grinding machine
3. Plain centre type cylindrical grinding machines

3. Internal Grinding machine:

As per the name this machine is used to machine internal surfaces which should be of cylindrical in shape but by using this machine we are capable to machine different cylindrical profiles which are already discussed in cylindrical grinding. The three main types of grinding machines are

3. Chucking type internal grinding machine
4. Centre less internal grinding machine
5. Planetary internal grinding machine

4. Special types of grinding machines:

These are some special kind of grinding machines which are used only for special operations and all these machines have different setups some of these machines are as follow:

1. Tool and cutter grinding machine:
   These are special types of grinding machines used for machining of cutting tools used for milling, turning and drilling operations. Grinding of a tool has two parts i.e. manufacturing of new tool dan re-sharpening of old tool. Simple single point cutting tool used in turning is machined or sharpened by using pedestal grinder or hand on bench type grinder whereas multi-point cutting tools such as milling cutter, drilling tools, hob cutters dan reamers are machined by sophisticated grinding machines like cutter grinder dan universal tool.
   
2. Creep feed grinding:
   In this process, high depth of cut is introduced with relatively low table speed. Main motive of such things is to complete whole operation in single pass so machining time reduces dan productivity increases.
   
3. Thread grinding machines:
   This is type of special grinding machine having special grinding wheel. This machine is almost similar with cylindrical grinding machine but it has very precised lead screw for producing accurate pitch on threaded part. This machine is used to produce very fine threads after grinding operation.
   

These are different types of grinding machine. 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.
