CNC Drilling Unit.30 (Type 2)
There are elements of the machine tool that are responsible for providing power and rotation speed of the chip tool. This product is used for drilling, bracing, grooving, forehead cutting, etc.
The unique features of Fragaman Sanat Paydar spindle unit are:
➤ Conventional machining spindle units use six-series bearings or roller bearings, which causes the spindle to be inaccurate enough. Meanwhile, in the manufacture of the company's spindles, precision bearing of grade P2 or P4 of seven series has been used, this has increased the rotational accuracy to 0.002 to 0.005 mm. Using this series of bearings requires sufficient knowledge in how to use and arrange the bearings and also calculate the preloading forces of the bearings in order to make the spindle stiff while working.
➤ On the other hand, it has provided an increase in transmission torque and rotational speed up to 3500 rpm
➤ The ability to transfer cooling fluid from inside the spindle and no vibration and high rigidity are other features of the product.
➤ On the other hand, spindles are produced in the form of separate couplings and by precision grinding method, which also causes weight gain, modulation, easier repairs and easier assembly.
➤ Also, unique bearing arrangement and force calculation for each spindle, including drilling, hammering, milling, forehead cutting and CNC in order to withstand the forces and no vibration, operation without looseness and also making super precise parts of spindle and housing spindle and assembly knowledge. The types of bearings to create the necessary rigidity, including the complexity of these products
