Empat Jenis Mesin CNC Esensial untuk Manufaktur Presisi

Obtaining precision machined parts from manufacturer will require component to go through range of processes to further create part to specific requirements. To accomplish this process, manufacturers use CNC machines. These automated machines use program control system as workers input required data that tells machine how to remove materials to create specified part. There are several types of CNC machines available when seeking out precision machining manufacturing processes. Type of machine selected for customer’s project will be based on type of material used, dimensional tolerances that need to be achieved, and how part will function in end application.

CNC Milling Machine

CNC milling machine is most common machine used in precision machining operations. Machine has rotary cutting tools that allow it to create shapes, grooves, holes, pockets, notches, and other face-milled or peripheral-milled features. CNC milling machines can move in variety of different ways as part can also be rotated, as they will be categorized by number of axis movements. These CNC machines are available as 2-axis, 3-axis, 4-axis, 5-axis, and 6-axis machines.

CNC milling machines work with wide variety of hard and soft metals including aluminum, steel. stainless steel, copper, brass, titanium, and many others. Machine produces typically square or rectangular parts.

CNC Turning Machines

CNC turning machines, also called CNC lathes, work by rotating part to remove materials and perform precise cuts. These machines have fewer axes than milling machines, as cutting tool removes materials around circumference of spinning part that rapidly turns on spindle to get down to desired dimension. CNC turning machines may create range of internal and external features on part, such as threads, drilled holes, reamed holes, bores, tapers, slots, and broaches. Common workpieces made on turning machines include bolts, shafts, and screws.

Dimensional tolerances reached on CNC turning machine are 0.01mm accuracy. Many materials may be used in turning machines, including stainless steel, copper, titanium, and brass. While aluminum may also be used, care is taken with this metal to prevent it from chipping. Manufacturers make cylindrical-shaped objects on turning machines.

CNC Swiss Lathes

CNC swiss lathes are another type of turning machine. Machine produces small parts that have complex features. Unlike traditional lathe machines that rotates part at fixed position, CNC swiss lathe also moves part back and forth along Z-axis. It operates using guided bushing as bar stock is fed into machine. Various tools cut away metal from portions of bar as it advances into machine.

CNC swiss lathes may have as many as 13-axises. These machines work well for short-run projects to create highly precise parts quickly. Large variety of metals may be used on CNC swiss lathe, including aluminum, titanium, copper, brass, and steel.

CNC Multispindle Drilling Machines

CNC Multispindle drilling machine drills several different size holes into part simultaneously at desired depth. They come as vertical drilling machines and horizontal drilling machines. Machine operates by using drill head with several mounted spindles. Spindles are on angular contact ball bearings or roller thrust bearings. Set of gears and AC motor drives spindles down into workpiece.

Machine is normally used for high volume production runs as spindles are set in rigid pattern. Soft and hard metals may be used with this machine such as carbon steel, stainless steel, copper, brass, steel, and aluminum.
