WHAT IS CNC MACHINE
How CNC Machine Works | What Is CNC Machining
A CNC (computer numerical control) machine is a high precision machine tool driven by computer-generated code. The controller software of CNC machine interprets the computer-generated code. This interpretation is then sent as electrical signals to make precise repetitive movements of various axis of CNC machine. The process of running CNC machines in user defined cycles to manufacture parts is called CNC machining. CNC machining enables manufacturing of various parts, dies, molds etc. in different materials such as wood, composites, aluminium, steel, plastics, glass and many more.
Below 5 steps summarise how CNC machine works and what is CNC machining. These steps are described in context of CNC Milling Machine or CNC Engraving Machine. Steps may vary depending upon other type of CNC machines, like CNC Lathe, 3D Printers etc. However basic concept is more or less same for any CNC machine.
STEP 1 – 2D CONCEPT DRAWING
This is the first step to manufacture any part using CNC machine. In this step simple line drawing is prepared for part to be machined. Line drawing can be hand sketched or prepared on PC in a CAD (computer aided design) software.
If 2D concept drawing is hand sketched, it is eventually scanned and imported into CAD software for further processing. Most engineering CAD drawing software have 2D tools to draw basic shapes like square, circle and triangle. Typical artistic CAD drawing software have tools like freeform sketching, text, text on curve etc.
STEP 2 – 3D CAD MODEL
In this step a 3D CAD model is prepared for part to be machined mostly probably on CNC Milling Machine. Also, bas-relief development for machining using CNC Engraving Machine or CNC Router Machine is kind of 3D CAD model development. Bas-relief is a type of sculpture that is achieved by carving a design into a flat surface. Relief has less depth than figures actually have.
Both 3D CAD model & bas-relief are developed based on 2D concept drawing prepared in step 1
A typical relief model development CAD software has many tools like sweeping, sculpting, combination of surfaces etc. to make relief development easy and fast.
STEP 3 – CREATE TOOL PATH
In this step a CAM (computer aided machining) program is generated using CAM software.
Usually many software companies offer CAD and CAM as single software package. Few software companies offer only CAM. In such cases user has to import CAD model for making CAM program. In CAM software various tools (for example milling or engraving tools) used for CNC machining are defined.
Based on selected machining strategy, tools and machining parameters CAM software generates path for tool movement on CNC machine. These tool movement are machine independent. CAM software stores this tool path data in machine independent files.
STEP 4 – CREATE NC PROGRAM
Once tool path is generated in CAM software, next step is to generate G-code.
G-code is a language that tells computer numerical control (CNC) machine tools what type of action to perform.
Most CAM software use inbuilt machine specific post processor files to read tool path data from machine independent files (generated in step 3)It is then converted in machine controller readable G-Code, M-Code NC program. Post processor take into consideration format required for specific machine controller along with machine kinematics for generating NC program.
STEP 5 – CNC MACHINING
In this step, actual manufacturing of part, die, mould etc. takes place. This process where CAM NC program file dictates the movement of machine to manufacture a part is called CNC machining.
CNC machining is fully automated with very little or no manual work required. Also, CNC machining is adopted in modern day manufacturing due to capability to run machines in predictable repetitive cycles.
In conclusion, CNC machining has become vital in the areas of metal and plastic production.
Where We Started | Where We Stand
It has been a challenging journey for N-GRAVETEK as a CNC Machine Manufacturer.
In 2004, we were using refurbished 3-axis CNC Milling Engraving Machine for job work services. During that time there were very few CNC Machine Manufacturer in India. So looking at the market demand we thought of manufacturing small low budget 3-axis CNC Engraving Machine. This Engraving Machine was basically manufactured cater Indian 2D & 3D CNC engraving market.
In 2008, N-GRAVETEK was formed and our first 3-axis CNC Engraving Machine was introduced. Since then we have been manufacturing products as per varied application demands. Furthermore, we get feedback from our existing customers and try to keep on improving our products. Today in 2020, we feel proud to have 250+ installations all over India for our 3-axis, 4-axis and 5-axis CNC Milling Engraving Machines.
Our Focus | Our Processes
Firstly, as CNC Machine Manufacturer we focus on quality. Secondly, our aim is to develop technology that increases the profitability for each customer. Thirdly, our team provides good customer support with less turn-around time. In conclusion, we want our customers to get true value for their investment from a trusted CNC Machine Manufacturer.
Each and every part we manufacture is scrutinised and goes under thorough inspection by our quality control department. We calibrate our products to get precise results with high accuracy.
Each and every machine manufactured goes under quality tests. Standard programs along with customer application specific tests are executed on the machine. The products are delivered to the customers only after they have cleared all the quality tests and customer is satisfied with the results of jobs realised for their application.

Machine Operating | Machine Maintenance
We provide complete training for operating the Engraving Machine.
Training is provided free of cost at our training centre in Nashik before machine dispatch. CNC engraving machine operating training includes basics like :
- How to clamp a work-piece on machine table ?
- How to get work origin at the centre of work-piece ?
- How to resume job from same point after power failure or tool breakage ?
Training also includes functionality with practical demonstration of each key of DSP controller.
Moreover, we also provide machine maintenance training. The machine maintenance training includes instructions with practical demonstration from our experts. Various aspects like how to do oiling for different components of CNC engraving machine, how to maintain spindle cooling system, how to do initial trouble shooting in case of break down are few of the many topics which are covered during maintenance training.
Above all, if you get our technology partners CAD/CAM software solution, we provide application oriented training for the same. This training includes advanced CAD/CAM starting from basics. Most noteworthy part of the training is that you get hands-on with CAD/CAM programs and actual machine run at the same place. In addition the training is customer application centric, as a result at the end of training, you become production ready.
