Perencanaan Mesin Poles untuk Proses Metalografi (CD + Cetak)
The polishing machine planning developed for the metallurgical laboratory is tailored to the needs of practicum students. The series of machine elements in the polishing machine are designed and calculated according to the specified forces and loads. The purpose of planning is to determine the dimensions and strength of the construction. The solution for calculating the strength of the associated machine elements is calculated according to standard calculations including calculating the strength of the frame. The power of the electric motor installed is 0.5 Hp, from the calculation of the transmission system for a polishing machine, the electric motor power is used which is used 0.116 hp to move the belt and pulley with engine speed of 1400 rpm and 700 rpm. The results of the calculation of the disk drive shaft diameter (d = 25 mm) the shear stress (σs) 2.8 kg / mm2 deflection (θ) 2.65 mm. The calculation result of the frame made of angled profile steel (40x40x3) with the maximum moment load received is 181073.107 N.mm, then the maximum load that can be accepted is 498.152 N. The dimensions of the bolt on the M-12 bracket with the load received by each bolt 9.06 kg experienced shear stress on the base plate (σs) 0.10 Kg / mm2.
