Panel Panel
In the case of the older Generation CNC machines, Mechanical systems are much capable of hold their life time then the
Electrical System. Hence complete electrical system & Partial mechanical elements can be renovated with modern electrical
system which is combination of New technology Control, Drives, Motors and standardized wiring panel (as below ) in Old
machines are Generally referred as a Retrofit.
RETROFIT Why we Need to Retrofit old CNC Machines?
Older Control Systems are much compromising with errors such
as ball screw error, backlash, Various friction, thermal expansion,
non-linear error and other symptoms of mechanical wears.
Improved control technology provides additional machining
cycles which improves productivity and significantly reducing
Machining time.
High accuracy, controlled feed rate particularly during contour
milling can be achieved by using advanced compensation
technique.
Improved user friendly programming & inbuilt profile graphic
support can provide additional support for operators which is
incorporated with Modern controls systems.
RETROFIT
Standardized new electrical panel & wiring will avoid system &
power supply failures due to the short circuit, ground fault &
defective old components. Therefore machine brake down time
can be minimized.
Most of the old machines Power supply & servo technology
(Analog) build in between 1980’s to 1990’s and Such Power
supply systems are either obsolete or difficult to maintain and
much power consuming which can be replaced with Digital servo
systems.
Improved Memory capacity of the Modern controls allow as to
execute complex 5-axis programs.
Spare parts supply can be extended for a longer period of time.
RETROFIT Factors Need to be Analyzed During the Machine Modernizing
Time Factors
- Delivery Time for Electrical package.
Time required to Prepare the Machine for Retrofit.
Installation & Commissioning of Electrical system.
Mechanical Corrections, if required.
Calibrating machine Performance with Laser.
Cost Factor
Retrofit expenses are depends upon the scope of work( Electrical & Mechanical) involved, how ever
Retrofit cost will not exceed 1/3 of the new machine cost.
RETROFIT
Some of the old System accessories can be utilized along with new system (Eg: Linear Scale, Rotary
Encoder for Table & Rotating head)
Note: Feasibility need to be conformed by System supplier.
Make sure most of the machine configuration & PLC functions are retained during the retrofit.
Additional PLC application can be added according to the End customer need.
RETROFIT HEIDENHAIN CONTROL IN MACHINE TOOL FIELD

RETROFIT Over 30 Years of HEIDENHAIN Controls
RETROFIT Complete Retrofit Solution from Single Dedicated Source
HEIDENHAIN Offers complete System package along with accessories such as Motors, Drives, Power
Module, Linear Scales & Rotary Encoder which are required for entire electrical Retrofit.
HEIDENHAIN Controls for Milling Machines and Machining Centers
TNC 640 Hybrid (Mill/Turn) iTNC530 Idle For 5-Axis Machining
Center
TNC620Simple Machines
RETROFIT New TNC 620
TNC 620 is Ideal Solutions for Old generation Machining centers consists with Outdated HEIDENHAIN
controls having Simple 5-axis and one spindle application.
Already with a reputation that clearly divides Heidenhain from their competition, the TNC 6XX Series
control is even easier to program than previous models.
The Compact Contouring Control for Milling, Drilling and Boring Machines
Stainless steel front, Ergonomically formed keys and Special protective paint reduces fingerprints
Improved Inbuilt Graphic features.
The large 15-inch TFT color fl at-panel display shows a clear overview of all relevant information
for programming, operating and inspecting the machine tool and control.
HEIDENHAIN Serial Controller Interface (HSCI) which reduces the number of signal cable
between Operator panel & electrical cabin.
Standard PLC Language with Improved Diagnosis functions.
Maximum 1024 PLC Input & 512 PLC Outputs Possible and multiple Inputs for PT100
1Vpp, EnDat and 11µAms (With Converter) Measuring Systems are Possible to connect.
HSCI
RETROFIT
HEIDENHAIN inverter systems and motors recommended
Advanced Milling cycles for complex contours and Cycles for drilling, boring , spindle
Alignment having upward compatibility with old HEIDENHAIN controls.
