About Us
The CEO / Managing Partner, B. Subbas Desappa started his career in Mahindra & Mahindra (M & M) after completing his Mechanical Engineering Degree with Honors.   He is from the first batch of Management Trainee of M & M, which is one of the largest companies in India that manufacture cars, jeeps, SUV's, tractors and aircrafts.  He was trained at American Tool manufacturers like Giddings & Lewis, Jones & Lamson, Brown & Sharpe, National Broach, Monarch, Waterbury Farrell etc. He commissioned their machines in India as well as in USA.  At Diesel Locomotive, Varanasi, with American Engineers, he commissioned various machines and machined components for diesel locomotive engines.  This factory had a joint venture of ALCO Locomotives of USA and Indian Railways to manufacture one engine per day.

threadaid, one of the earliest in this country, mainly to manufacture thread rolls and regrinding them, was started in the year 1974.  Since 1997, threadaid became a family partnership firm of Mr. Desappa, his wife Yashodhra and his two daughters, Reena Charles and Rowena Rinku Peters.  Mrs. Desappa looks after company administration and Mr. Desappa looks after designing, production of various machines and their tooling.   threadaid has been manufacturing CNC/Hydraulic Thread/Spline rolling machines with their own design, since 1998.  Now we manufacture CNC Rack Rolling machines also.

Due to its strength in designing and manufacturing, threadaid has designed and manufactured the following machines for its own production use. 
1. Double column band saw machine to cut D2 die steel rod up to ?225 mm.  This machine cuts 225 mm ?within 0.5 mm taper. 
2. Highly accurate master grinding machine to grind masters of annular grooves within microns with different pitches and pressure angles required to form the grinding wheels, of our 2 nos. Matrix and 2 nos. Reishauer gear grinders. 
3. Temperature controlled stress relieving furnace, using special high temperature oil, to stress relieves the dies after gear grinding them. 
4. Sub zero treatment equipment to complete the heat treatment process for better roll life. 
5. Universal measuring equipment with 14" screen optical comparator with 20X & 50X magnification lenses to inspect thread / spline forms. 
6. CNC Thread grinding machine, to grind special thread rolling dies, to roll components like 11.1125 pitch x 4 starts.  The very special feature of this machine is, it can also grind thread rolls with number of starts like 11, 13, 17 and 19 etc. 
7. Rack grinding machine to grind racks for rack rolling machine. 
8. Internal grinding machine to grind bores of spline / thread rolling dies.   


Main strengths of Threadaid:
1. We use a high precision Swiss made 'Dixi' jig mill to machine all important components required for our machines. 
2. All machines and components are designed with the help of AutoCAD. 
3. We have developed our own software to design circular spline rolls and racks for rack rolling machine. 
4. One of our main strength is we conduct seminars on spline designs and standardizing splines for customers.   This standardization helps customer to minimize the tool cost and helps avoid the use of several hobs and broaches. 
5. Records are meticulously maintained of all the rolls manufactured and reground by us.
6. Our customers use our machines and tools to manufacture and supply components to manufacturers like Suzuki-India, Honda-India, Tafe, TVS, Metro Rail, two wheeler manufacturers, aircraft manufacturers (HAL) We also supply machines and rolls for manufacturers of Fluted rolls for textile machinery and components for home appliances like washing machine, mixers etc.
7. We supply various tonnage machines according to the customer requirement for their jobs up to 60 ton capacity.



Our Sister-Concerns are:
a. Splinetech (Proprietor - Mr. B. Subbas Desappa) - manufacturers of circular spline rolling dies, spline rolling racks and special thread rolling dies for components like special brake screws for Metro Rails. 

The racks manufactured by Splinetech are used in CNC Rack Rolling machines manufactured by Threadaid, to roll components for Suzuki, Japan as well as Honda, Japan for their latest vehicle.  We have also supplied Racks for Rack Rolling machines at Hyundai.

b. Rohri Industries (Reena Charles) - Software Development.

c. Spline Racktech (Proprietress - Mrs. Yashodhra Desappa) - supplying components for Threadaid.
