Klingspor is entering the diamond cutting blade market by investing in a state-of-the-art production facility for its Ukrainian factory

Klingspor, the German manufacturer of coated abrasives and bonded abrasives, is entering the diamond cutting blade market by investing in a state-of-the-art production facility for its Ukrainian factory. Easily re-dimensioned, this site is designed to accompany the manufacturer in its planned growth at global level.

Having commenced manufacturing of abrasives at the very end of the 19th century, today Klingspor is a global manufacturer in this industry with twelve manufacturing locations and generating a turnover of more than 260 million Euros with 2,700 employees. Recognised for its product lines of coated abrasives and bonded abrasives, until recently the Group was virtually absent in the diamond sector, where it only offered a small product line, which it sourced from partners.

Since May 1st 2015, the situation has evolved considerably with the introduction of the first diamond product line designed and manufactured by the German firm; for this opportunity Klingspor has invested in a high performance facility for its Ukrainian plant in Velyki Mosty, located 50 kilometres north of Lviv, near the Polish border.

Manufacturer or nothing

Committed to a strong industrial strategy, the Klingspor Group has manufacturing at the heart of its DNA and offers a product line consisting almost exclusively of items that it produces in-house. Diamond cutting blades, a product line that accounts for only 3% of its turnover, had a particular position and the question was finally raised of investing in the firm's own means of production. Thus, three years ago the decision was made to expand in the diamond cutting blade market, and since this date the firm has been looking towards a global market in which it should become one of the major players.

To date, the first three steps have been taken, and the subsequent steps are already in the business plan to accompany the growth of the activity.

German development, Ukrainian production

The first phase of the Velyki Mosty plant was erected in 2010 to manufacture flap wheels, abrasives that require many manual operations and that have a definite economic justification in the Ukraine. As the facility had available capacity and the presence of qualified personnel in the Lviv region, the site was chosen in 2012 to accommodate the Group's diamonds, within a unit that would be dedicated exclusively to production.

Therefore in 2012 the Klingspor Group decided to expand its Velyki Mosty plant in the Ukraine, which was constructed in 2010 to produce flap wheels, by erecting a second production facility dedicated to diamonds on a 100,000 m² building lot. The following year the first machines were received, others were received in 2014; machines which likewise would be devoted to production of the first diamond cutting blades. Finally on May 1st 2015, the new Klingspor line of segmented diamond cutting blades was launched with the series 300 Extra for the low end, 600 Supra for the price-performance ratio and 900 Special for the high end and the intensive applications.

As emphasised by Wolf-Dietrich Pflaumbaum, the senior executive responsible for the diamond project at Klingspor, "This is a long-term approach that will ultimately make Klingspor one of the big names in diamond cutting blades on a global level ". Ramp-up of the plant has been programmed in this direction with the successive investment phases, in terms of infrastructure, purchase of machines and training of personnel.

In fact, the Klingspor research and development service, with its own production line for diamonds, is based in Germany at Haiger, with employees that include Ukrainians to facilitate exchanges with the Velyki Mosty plant. All of the studies are implemented in Germany and as soon as the products are certified, large-scale production will start in the Ukraine, where supplemental tests will be executed in the course of manufacturing and at the end of the manufacturing process. Moreover, in line with this concept, all the components are tested in Germany before they are used for manufacturing in the Ukraine.

Competitive European plant

With regard to organisation, the Velyki Mosty plant pursues the principles that guide the diamond disc production sites, however with optimisation of each phase in accordance with the local environment; thus partial automation can selectively be preferred over total automation due to the Ukrainian cost of labour. At the same time the process involves state-of-the-art production machines to manufacture high performance cutting blades at competitive prices, with constant concern for the total safety of the finished product (thus all the segments are laser-welded), the production process is executed in a work environment that is comfortable for personnel – no waste discharge, air conditioning with hourly air change, etc.

The diamond cutting blades are shipped to Germany twice a week (where a new logistics platform will open in the first half of 2016), a small portion are directed to Poland and a last portion are reserved for the domestic Ukrainian market.

Three tier product line

The product line manufactured by Klingspor extends from 100 mm to 500 mm diameter with three quality levels, which are, in ascending order, the 300 Extra, the 600 Supra, and the 900 Special. The product line is organised in different series that are identified by colour coding: Asphalt (black), tiling (green), refractory bricks (blue), concrete (red) and universal (white).

Designed in Klingspor's R&D laboratory, the different compositions, binder blends and diamonds (coated with titanium or not coated with titanium) and geometries are specific to the brand and enable very high performance. "There is no modelling, but rather the expertise which the brand was endowed when we accepted the challenge of diamond and experimentation", recalls Wolf-Dietrich Pflaumbaum, who adds, using the DT 600 U universal cutting blade as the example

“We want to be superior to other brands, like with this cutting blade this is the optimum of what a customer can expect due to its characteristics, service life and cutting speed". This quest for quality is directly linked to the brand's determination to establish itself in the international market of premium diamond cutting blades. Thus Klingspor's approach, oSa certified, is to offer only high quality, laser-welded diamond cutting blades at competitive prices. "We are positioning ourselves just below the market price of the major players with a proven superior quality". Moreover, manufactured in Europe, this product line is differentiated from the numerous Asian products that are marketed on our continent, in particular through the advantage of product availability that is much more efficient.

Marketing support

In parallel, Klingspor provides all the required commercial support, with technical consulting and training offerings, accompanied tours, participation events and open houses, telemarketing, implementation of personalised promotions with a mix of abrasives and diamonds, or promotions specifically devoted to diamonds.

Klingspor also has effective marketing in which diamonds will be totally integrated from now on. Thus the brand is developing self-service presentations (1 to 8 meters) profiled with the distributor main building diamond signage that presents the 20/80 of the product line and enables immediate commencement with the brand and requires minimum space in the store.

The Velyki Mosty plant has a surface area of 5,760 m², of which a 1,440 m² hall is for the diamond business. It employs 150 people; one third are involved in the production of the diamond cutting blades - two teams at present with a third team planned for the future. As emphasised by Wolf-Dietrich Pflaumbaum, Klingspor senior executive, "the people are very loyal and interested in our project. They have ideas and this works very well for the enterprise".

The raw materials (diamonds) are stored in a room where access is protected by biometrics (fingerprints). The manufacturing progresses, starting with mixing the diamond with its binding agent to transform it into granules with dimensions, weights and naturally the shapes that are precisely known. In the subsequent phase this knowledge makes it possible to precisely prepare the segments and to effectively calculate the cold pressing that must be applied to mould them in a homogeneous manner - good granulate produces the perfect segment. Blending and granulation are executed in a controlled atmosphere, including strict humidity control; humidity must remain under 50%. Klingspor has two machines for granulate weights up to 20 kg.

The segments are moulded by cold pressing in machines that produce six segments at a time; 20,000 segments are produced in an 8 hour shift, compared with 6,500 segments using conventional machines. This machine makes it possible to form the segment and its lug very precisely. These elements are then welded to the steel core or welded again to place three hardnesses of different binders in the same segment to perfect the performance for certain specific applications.


The segments are laser-welded onto the steel core, which has been degreased beforehand. After welding with these machines, which are the most advanced in the world, with a tolerance of one hundredth of a millimetre, with inspection of the entirety of the weld, all of the segments are tested with a destructive test on the first blade of a series at 200% of the DIN specifications, and a test for compliance with the DIN specification is performed on the subsequent blades.


Segments are deburred at the level of the lug to guarantee the precise shape of its radius, as well as the precise height of the piece.


The manufacturing process for the diamond cutting blade is almost concluded. The large discs with a diameter greater than 300 mm are balanced. For the small diameters the segments are sharpened automatically and for the large diameters the segments are sharpened semi-automatically. The disc is polished and coated with a varnish for a better appearance. Finally, all the information concerning the blade, such as the batch number, is engraved and applied in the centre part of the blade, using 5 colour pad printing which replaces the traditional paper label. Random tests follow these final operations. The random tests are for quality control of the blade, they test "for the existence of any geometry or safety problem that has not yet been detected"

Klingspor has test equipment that tests the interior and exterior of the diamond cutting blades to determine the performance of their blades and competitor's blades (speed, wear over x cuts, regeneration of the diamond, etc.). Notably Klingspor has a test area with different surfaces: Steel reinforced concrete 16 mm in diameter, steel reinforced concrete 12 mm in diameter, steel reinforced concrete 6 mm in diameter and asphalt. In the test area a thermal chainsaw mounted on a carriage for cutting asphalt is equipped with a DT 602 A disc 350 mm in diameter, and the same machine used to cut a concrete edge is equipped with a DT 600 U disk 350 mm in diameter.


The Velyki Mosty plant also accommodates flap wheel manufacturing, the site's initial activity since 2010. Some 15,000 flap wheels are manufactured daily, in accordance with a process. In the first step the coated abrasive belts are cut in to pieces and placed in the circular profiles. Then the resin flows to the centre which additionally receives the shaft. The plant also laminates the velour backing on the jumbo (a large roll of coated abrasive product).
