Two large milling centers for the turkish leader in agricultural machine manufacturing
10 Mai 2021
JUARISTI builds two new milling centers for the largest Turkish agricultural machine company, making a total of five JUARISTI brand machines in the multinational’s facilities. The two new centers are characterised by the multiple automation options they include.
Hisarlar is a large Turkish company that manufactures agricultural machines. It was founded as a family company in 1973. It currently employs more than 800 people and has facilities that are more than 97,000 m2. It quickly consolidated as the principal manufacturer of tractor cabins in Turkey and became a supplier for world renowned heavy machinery manufacturers. And in 1985, it started its own production and added implements like seeding machines and foraging equipment to it catalogue.
In 2017, it was acquired by the Indian automotive multinational Mahindra & Mahindra, whose agricultural division is one of the principal tractor manufacturers in the world, with a production of around 15,000 units a month. The acquisition, a milestone in Mahindra’s strategy for dominating the Turkish market, was accompanied by an ambitious growth strategy that included expanding facilities and renewing equipment. In the framework of that strategy, Mahindra wanted to acquire two new milling centers for machining medium and large components for their machines. JUARISTI customers since 2006, they already had a TS1 compact boring machine, three TX-S boring and milling centers and an MX5 moving column boring-milling machine. Thanks to the good results of the previous machines, they once again trusted JUARISTI with their new project through Teknikel, their habitual contact, which is a well-known company with a branch for distributing machine tools that has represented JUARISTI in the country for more than 40 years.
Subsequently, a join project was begun where JUARISTI experts analysed the production needs of Hisarlar. JUARISTI and Teknikel representatives travelled to the Hisarlar facilities in Turkey to study the pieces that needed to be machined, which were notable for their large size and complex shape and would require milling operations from different angles. JUARISTI recommended two T type milling centers with rotating tables and integral automation.
Reliable Performance and Maximum Productivity
The TX series stands out for its thermo-symmetric design with a head centered on the column, which provides maximum precision and rigidity while machining. Furthermore, all the structural elements are made of pearlitic cast iron to absorb vibrations better.
The Hisarlar solution includes an ACD1 universal head with 1°x1° automatic positioning, high power (40 kW) and 1,400 Nm spindle torque with automatic lubrication of the high precision main gears.
The center also provides very high productivity, with 30 m/min feeds on the X, Y and Z axes. It has two 1,600×2,000 mm pallets and a load capacity up to 8,000 kg to facilitate machining.
The table rotation has hydrostatic guiding and is driven by a double motor and double pinion with a master-slave system for eliminating backlash. It also has external and internal cooling.
In the automation section, the machine has an automatic pallet changing system (APC) and an automatic tool change (ATC) system with a capacity of up to 60 tools and the ability to make changes horizontally or vertically.
The pre-acceptance of the first machine happened at the JUARISTI headquarters with the attendance of five engineers from Hisarlar and two from Teknikel. After the geometric verification was complete, JUARISTI gave all the engineers training that included advice about the operability of the machines and its accessories, handling the CNC control and aspects of maintenance for the mechanical, hydraulic, electrical and CNC areas.
JUARISTI in Turkey
JUARISTI started its expansion into Turkey in the 80s. Since the beginning it has cooperated with Teknikel, the leading company in the Turkish machine tool industry. They have main offices in Istanbul and Ankara and they have local agents in most of the industrial areas in Turkey.
The engineers at Teknikel have visited the JUARISTI headquarters in Spain several times and they have received training on different boring and milling machines and in technologies included in JUARISTI machines. The Teknikel engineers participate in all JUARISTI projects in Turkey and they travel to the JUARISTI headquarters to attend the machine pre-acceptances with the customers. Furthermore, they are in charge of installing and commissioning the machines in their country and they ensure rapid responses and integral professional services to all the company’s customers.
The more than 40 years of cooperation between Teknikel and JUARISTI has been a factor in the company’s success in Turkey. During that time, JUARISTI has supplied milling and boring machines to highly prestige customers like Hisarlar, Hidromek, Akdas, Ford, Polat, Eregli-Erdermir, Yilmaz, etc…
