If you're looking for a cost-effective way to improve your CNC Machine performance, keep up with the latest control technologies and maintain the machine's value over time, then it's time to consider a CNC Reconditioning/ Remanufacturing/ Retrofit.

Getting your CNC Machine Reconditioned it is necessary to stay competitive. Whether you're in the manufacturing, machining or metal fabrication industry, it's critical to maintain a current machine tool for peak performance.

The most important asset for any factory/shop floor manufacturing precision components is its Machine Tools. The reason:

  1. Machine tools are capital intensive
  2. They consume significant real estate on the shop floor
  3. Need skilled manpower to run them
  4. They help in high volume production 

Hence it's absolutely imperative to make sure that you protect your asset, get the most out of it and maintain its viability for many years. How do you make sure of this? 

Depending on whether your machine tool is a conventional type, hydraulic operated or CNC there are ways to ensure their viability:

  1. Machine tool reconditioning 
  2. CNC Remanufacturing
  3. CNC Retrofit

Some of the major advantages of following through with Recondition/ Remanufacturing/ Retrofit are:

  1. Significant cost saving as compared to buying a new machine
  2. Increased machine life
  3. Improved performance 
  4. Standardization

Machine tool Reconditioning 

Due to years of running and load any machine tool needs to be reconditioned to maintain accuracy and productivity. Most critical aspect in achieving precision depends on a machine’s geometrical accuracy. Due to wear and tear geometrical inaccuracies are introduced which are rectified by reconditioning. 

Below points details the general process for Reconditioning any machine tool:

  1. Complete machine dismantling, cleaning and painting. 
  2. Replace all the worn-out parts to new – Ball screws, guideways, bearings and other mechanical transmission elements. 
  3. Scraping, blue-matching and alignment to achieve perfect geometrical accuracies. 
  4. Reconditioning or replace hydraulic, pneumatic and lubrication systems 
  5. Complete servicing and if required re-wiring of electrical circuitry 

For older CNC Machines customers combine CNC retrofit along with CNC reconditioning.

CNC Conversion / CNC Remanufacturing

Process of converting a manually operated general purpose machine (GPM) or a conventional machine to a fully CNC operated machine. Typically, the process involves incorporating mechanical transmission elements like ball screws, slides, bearing, bearing housings, servo motor mounting arrangements for CNC compatibility. The complete electrical circuitry and cabinet is newly designed to incorporate all the CNC related elements. 

Benefits CNC Conversion 

  1. A fully operated CNC Machine increases productivity and improves production capacity due to lesser manual intervention. 
  2. CNC Machines enable complex task details like axis movement and auto compensation. 
  3. Creates flexibility in manufacturing and increases safety. 
  4. Reduces errors due to manual intervention. 
  5. Cost Benefits: Depending on the size, type and complexity of the machine CNC conversion costs between 35%-50% of the cost of a new machine. 
  6. Save on taxes and moving costs for your machine (Cost benefits are significantly higher in imported new machines – Upto 70% cheaper) 

CNC Retrofit 

Older CNC and manual machine tools that are mechanically sound, can be retrofitted with the latest control system like Fanuc/Siemens/Mitsubishi/Allen Bradley. Typically CNC retrofit involves replacing the CNC control, servo and spindle motors, drives, electrical components along with the existing wiring on a machine. In many cases mechanical upgrades like new ball screws can be incorporated that were not available when the machine was originally purchased. 

Benefits of CNC Retrofit

  1. Benefits depend on the size, number of CNC axis and type of the machine.
  2. On an average retrofitting a good machine is less than 40% of the cost of a similar new machine.
  3. Productivity improvement can cost as little as 1/3 the cost of a new machine and with a short down time. 
  4. Save on taxes and moving costs for your machine.
