At a glance
Focus: Leading India towards Industry 4.0
Challenge: The company was facing a severe problem with data collection in the manufacturing process, and their manual method was giving rise to inconsistencies — long reporting delays, unreliable data validity, and downtime estimates based on guesswork rather than actual measurement, across a mixed fleet of 21 machines from different makers and eras.
Approach: As often explained by management, Ace Micromatic works on a model for innovation that is market-need driven and customer-cost conscious — leading AmiT to deploy its TPM-Trak real-time tracking suite tailored to Sphoorti's varied shop floor.
Impact: The results were immediate and surprising: real OEE came in at just 58% versus the company's earlier estimate of 84%, while automated reporting and improved visibility drove a 20% cut in production loss hours and a 30% rise in machine utilization.

To achieve these goals Ace Micromatic has a clear growth map in place.
-
It is increasing its international market through exports. Currently exports account for 10% of the company’s turnover but the plan is to increase this to 15% in the next few years. The company has increased its market presence in several countries and now operates across Asia, Australia, Middle East, North & South America and Europe.
-
It is increasing capacity. In 2013 Ace Micromatic invested approximately Rs 100cr to set up a foundry for captive consumption at a 10- acre facility at Minnapura, India, with plans to increase capacity to 10,000 machines by 2020. This has been up and running since January 2016, at 40-42 percent.
-
It is planning to specialize in bigger castings of one tonne and above. The castings business is expected to create a new stream of revenue and enhance the export profile.
-
As a group, Ace Micromatic invests about 2- 3% of its turnover in R&D, with a department for development at each factory. The company has plans to widen its product offerings and explore high-end machine tool building. This includes complex machining for aerospace, medical equipment and similar top-tier manufacturers.
Home Grown Production
A key driver for Ace Micromatic’s competence is the indigenous nature of its product development and manufacturing. Over 80% of components are sourced and built in India with only the computer system, drive, ball screws and bearings imported. The imported parts constitute only 55% of the total cost of the
machines. The raw material for machines is sourced from domestic foundries as well as the company's own foundry. According to TK Ramesh, Chief Executive Officer, Micromatic Machine Tools Pvt Ltd, “We continue to work on automation, robotics and gantry systems, with cost-effective solutions. We're focused on
providing Indian solutions that work for Indian SMEs." The company credits 70 to 80 % of its design and development activities to be customer demand driven.
Ace Micromatic has a history of designing computercontrolled solutions for the Indian market that are manufactured in India. Back 1982, gauging the market demands for a CNC (computer numerical control) machine, the company’s founding directors decided to begin local manufacturing of their prototype designs.
In those days CNC machines were imported and the process included long government procedures and a 300% custom duty. The aim was to make affordable CNC machines for the local market without external support.
To date the company has no foreign collaboration or investment but has been exceedingly successful in developing products that are viable in the India market. Both AMS and ACE Designers have been recognized by the Department of Scientific and Industrial Research (DSIR).
Customer-Centric, Affordable, Accessible
Today the Ace Micromatic group nurtures ambitious plans to move up the value-curve by offering design driven ‘Industry 4.0 ’ solutions to customers such as customised OEE (overall equipment efficiency) and real-time machine-monitoring. The solutions allow manufacturing companies to gain visibility into their shop operations up to a cycle.
Nearly 60% of its customers are SMEs with whom the group shares a close connection. For some of these small businesses Rs 15-20 lakhs investment on machines is a large outflow. The group prides itself on training and helping customers attain productivity through close relationships and hand-holding. As TK Ramesh points out, “Our success can be attributed to our collective ability to convert designs into making products cost effective. Looking back at the three decades of operation, we can confidently say that Micromatic played a key role in nurturing the SSI’s & the SME’s to adopt CNC technology and move towards global quality levels, through providing them with affordable CNC technology and close hand holding.” “I think it explains why we have the maximum share in the Indian CNC market,” he adds.
The shift towards smart-manufacturing in India puts Ace Micromatic in a unique position to introduce ‘Industry 4.0’ technologies to its customer base and gives it a degree of first-mover advantage in the SME space.
Sphoorti Machine Tools Pvt.Ltd
Sphoorti Machine Tools Pvt.Ltd is an excellent example of Ace Micromatic’s customer focus at work. The company is small enterprise specializing in the manufacture of Tool Discs and Tool Holders. It began in manufacturing in 1996 with two Machining Centers, and over the years the company underwent many stages of development to emerge as one of the India’s leading manufacturers with 40% of sales exported globally.
Business challenge
The company however was facing a severe problem with data collection in the manufacturing process and their manual method was giving rise to various inconsistencies.
There was a large time lag in collection and in some case the reporting took months
The validity of their manual data was under question
The suspected ‘down-time’ of machinery as perceived by the operator was an estimate and not based on actual measured specifics.
In 2015, with the intent to meet the increased demand and lower overheads within existing capacity, Sphoorti made the calculated decision to apply real-time tracking of data to increase operational efficiency and shift towards more automated processes and data analytics. The problem was; Sphoorti had a varied manufacturing line with 21 machines from different manufacturers and different CNC controls makers (some were Siemens and some were Fanuc). Some of the machines were nearly 15 years old while others were recent purchases. Finding a solution to address these incompatibilities was crucial.
Sphoorti brought AmiT experts (AmiT is Ace Micromatics ‘smart’ solutions vertical. It aims to offer innovative technology solutions for progressive organizations) to study their shop floor and suggest the possible solutions. After understanding the problem in detail, the team form AmiT identified two applications that would address the concerns. These were then evaluated for cost-benefit ratios with the eventual decision to upgrade data-tacking entirely to AmiT’s TPM-Trak technology suite. It took a period of 6 months to deploy.
Industry 4.0 solution
As often explained by management, Ace Micromatic works on a model for innovation that is market need driven and customer cost conscious. The company has to, given the business model of its customers. Even as it moves up the value chain Ace Micromatics is not planning to lose sight of this by any means. For most of its customers “automation is not the solution due to cost. Therefore, they are left with addressing only the non-productive cost, which cannot be controlled without adequate data. “We thought that there can be some level of smartness that can be built into the machines and TPM Trak emerged,” Ramesh explains (TPM Trak is Ace Micromatic’s elite suite of products designed to provide Industry 4.0 solutions). Currently the group has deployed TPM Trak in hundreds of machines, most of whom are suppliers to OEM’s claiming that customers have enjoyed productivity gains of 10 per cent to 30 per cent, ensuring very high operating efficiencies.
As the group innovates further to address the needs of SME’s grappling with the Smart Manufacturing wave, it can have a significant part to play assisting a section of manufacturers that often get overlooked by top-end cutting-edge ‘expensive’ solutions.
Key benefits
| Area | Outcome |
|---|---|
| Operational Benefit | The results were immediate and surprising: |
| Visibility & Analytics | Sphoorti realised that its manual efficiency calculation of 84% was an optimistic projection at best. The actual OEE measured using TPM-Trak real-time data showed a marked difference dropping to a mere 58%. |
| Visibility & Analytics | Not only did the technology help get a realistic picture of the shop-floor, it also provided Sphoorti with automated reports allowing for better decision making and immense gains in productivity. TPM-Trak production reports were utilized to address production issues rather than worry about availability of data or its validity. As a result Sphoorti saved 20% of production loss hours just through managerial efficiencies. |
| Cost Savings | Internal utilization of machines increased by almost 30% saving the company added costs of additional machines, manpower, land and consumables. They could now clearly & precisely know how management losses contributed to slowing production and lesser machine utilization. |
| Operational Benefit | Today Sphoorti installs TPM-Trak on all new machines on its shop-floor from day one and their production meetings are conducted using TPM-Trak dash-boards and reports. The company is now planning to go paperless by utilizing e-SHOPx, products from AmiT. |
| Visibility & Analytics | M Gunasekaran, plant manager at Sphrooti machine tools explains the benefits, “We are monitoring our total manufacturing efficiency through TPM-Trak. This includes program transfer without machine disturbance, verification, actual cycle time analysis, actual loading and unloading analysis, machine down time analysis on a daily and weekly basis, etc” |
