This is a piece of critical equipment for machining metal parts and components. This features a computerized automatic tool change function. These perform machine operations with high precision and quality and give a high surface finish.
These are multi-functioned machines and allow great flexibility to carry out a high number of machine operations such as boring, milling, threading, drilling, etc.
There are various machining centers based on function, number of axes, dimensions of the working area, and also spindle positions.
It is defined by the size of the spindle operating area which depends on x, y, z transversal axes. These dimensions affect the maximum size of work pieces and also the type of machining that can be done. Once the characterization of the spindle position is done.
Identification Of The Following Features Is Very Important:
- Number Of Tools
- Controlled Axes
- Fast-Moving Speed.
- Machine Structure
- Numerical Control
Important points to be considered while buying a used machining center:
Exact Typology Of A Machining Center
A brand or model rather than another. There are usually 3 types of machining centers based on their structures:
This is also called milling which relies on the rotary cutters usually to remove metal from the work piece.
Horizontal machining occurs in the horizontal machining center (HMC). This employee has a spindle that is parallel to the ground floor. With this spindle, tools stick to the side of the holder and cut across the side of the work piece.
This encourages chips to fall away from the table.
Vertical machining occurs in the vertical machining center (VMC). This employee has a spindle that is vertical to the ground floor.
It is a bridge-like portion of certain cranes. It is usually a structure that bridges over an area. This moves on wheels. This is specially used for cutting flat steel plates because it is easy to move cutting torches in the X-Y coordinate system.
The gantry cutting runs on some rail systems on X-axis, either pedestal mounted or floor mounted and even sometimes mounted to both sides of the table.
The rails are specially designed to provide accurate motion for the machine. These are strong enough to support the weight of the entire machine.
Hence, this is the meaning and technical specifications, types, and classifications of a machining center. Hope this guide helped you.
