CNC industry growing significantly

February 12, 2015 2:24 pm

The engineering industry in India has grown significantly across all segments. Let us explore how this growth is fuelling the demand for quality CNC machine tools
——————–The machine tools sector has been seeing revolutionary technologies now instead of the evolutionary technologies which were used earlier.
Keshav Khurana, Executive Director, Wohlhaupter India IntroductionIn earlier days focus of machine tool industry was mainly for mass production and automobile industries. However, in recent days the focus is being shifted to technological products like aerospace industries, boring machining, energy sectors like turbine machining, wind mill, railways crank cases. High speed machining with lot of accuracies possibilities with double ball bearing technology spindles has really created an interest for end users who really want to compete in this market with technological products.
The Indian machine tool industry has been able to meet the growing demand with a mix of local made CNC machine tools and imports.
Recent developmentsGlobal machine tool builders have now set up offices and manufacturing bases in India and this influx of technology and investment is driving the industry to newer heights.
“The machine tools sector has been seeing revolutionary technologies now instead of the evolutionary technologies which were used earlier. Robust designs, quick and precise machining these are all advantages which the customer hence gets,” says Keshav Khurana, Executive Director, Wohlhaupter India Pvt. Ltd.
 “The business environment in India is also being simplified with a clear focus from the government to reduce duties and taxes and bring these in line with global norms. This is also helping both Indian and foreign machine tool builders looking to grow in the Indian market,” says Terrence Miranda, Managing Director, HAAS Automation India Pvt. Ltd. and also describes two major driving factors as follows:• CNC machine tools: Machining centres and turning centres are becoming faster, more accurate and capable of more complex machining tasks every day.
• Automation: The extensive use of automation can be seen nowadays. Rrobots loading/unloading parts or automatic pallet systems or barfeeding systems is a clear trend that is being seen in India.
The need to machine a complex component in a single set-up is also growing. CNC turning centres with 3, 4 and 5 axes and CNC machining centres with 4 and 5 axes are contributing significantly to enhanced accuracy, reduced part handling and overall productivity.
Initiatives taken Wohlhaupter has come up with a fine boring head which covers boring range from diameter 6 mm to 128 mm. It can be adjusted in 2 microns diametrically. The body is serrated for a strong clamping and comes in through coolant arrangement; it is balanced at 12,000 RPM. This boring head comes in a cost-effective kit which ensures customers get the same Wohlhaupter quality at an enticing cost.
“The boring range covered by us of diameter 0.4 mm to 3,255 mm is the largest range in the industry. We also give servicing support at our Delhi head office, all tools can be serviced at the specially set up service facility,” informs Mr Khurana.
“Simple innovation and providing true value to our customers is a mantra at HAAS,” says Mr Miranda. “In line with this philosophy we have launched a number of new products recently which provide simple, innovative solutions to the machining needs of our customers.
HAAS offers a range of high performance 5 axis machining centres in vertical or horizontal configurations to machine a range of complex components such as impellers, blades, cylinder heads, cylinder blocks etc. in a single set-up.
The new UMC-750 five-axis Vertical Machining Centre offers a generous capacity of 762 x 508 x 508 mm in the X, Y and Z axes respectively. It features a two-axis, 630 x 500 mm integrated trunnion rotary table with +110 and -35 degrees of tilt and 360 degrees of rotation to provide excellent tool clearance and large part capacity up to 300 kg. Also featured is a 40+1 side mount tool changer and a 40-taper, 22.4 kW, 12,000 rpm direct drive spindle.
The new ST series CNC turning centre from HAAS set the standard for quality and affordability in complex CNC turn mill applications and provides high end options such dual spindles, C axis, Y axis and powerful live tooling, all at an affordable price.
Present challengesThe global business environment continues to be uncertain and this continues to challenge industrial recovery in India as well. Infrastructure in India continues to improve with major reforms in power, roads and rail sectors to name a few. This along with reforms in regulatory and tax framework needs to continue at a rapid pace if India is to be a manufacturing hub for the world.
“There are operational challenges in every business and we are no exception to this. We have focused on setting up a world class sales, service and applications team backed by infrastructure and the latest CRM systems and processes which all contribute to us providing unbeatable value for our customers,” says Mr Miranda.
