Amin Machinery Private Limited

We manufacture premium quality columns and boom manipulators with a much better deflection figure than any of our competitors in the market. Our range of column and boom is correct with controlled deflection relative to height, boom travel and weight to be carried. Thus it offers optimum performance and reliability.   
 
Salient features:
 
The columns of both the RC and TRC types are supported on precision cross roll bearings. These bearings are sourced from SKF/Rollix, who is the leading bearing manufacturers. The larger machines have preloaded cross-roll bearings, to eliminate the free play, and which is extremely important since any play in the cross-roll bearing is considerably increased at the end of the boom when it is in the fully raised and fully extended position.
 
Column rotation can be motorized, but in any case all machines have a manual locking arrangement to lock the column in any of the 360° positions. The boom saddle, or carriage, is fitted with rollers which travel along the machine slide-ways. Each of the rollers is fitted with 2 preloaded Taper Roller bearings carried on eccentric shafts. The Rollers can be adjusted for wear and tear and also for precision and vibration-less travel
 
Boom elevation is through high torque AC geared motor incorporating an electromagnetic brake, the final drive being through rack and pinion. Other competitors employ chain elevation which is not very compatible and doesn't eliminate bounce. Bounce accumulates particularly where a welders platform or lay trough is fitted and is aggravated by any movement of the welder. Other competitors in the market still use lead-screw elevation, which is not very viable since flux, dust and others accumulate and the lead-screw then becomes locked in the lead-screw nut.

AMIN PANELS, one of the biggest manufacturer of Low Voltage Electrical & Electronic Control Panels, started its operation in 1974. The plant is located on a 5Km site at Anand (V.U.Nagar), near Baroda /Ahmedabad (Gujarat). It commands a major market share in its product range category.

Major strength of Amin Panels are modern manufacturing facilities which include sheet metal workshop equipped with Shearing Machine, Plate Bending Press Break Machine, Painting technology with bake up oven, tool room, quality control systems including Test Benches as per IS and IEC standards and well equipped design center. In addition to above modern equipment & machinery, we have skilled manpower, highly qualified experienced Engineers, supervisors, Inspector & service technicians for providing prompt & best service after sales requirement, also we have design center, which design the panel to meet the client's requirement. We can therefore, state that we are in a better position to under take manufacturing & supplying of Panels exactly to design / specifications and drawings of ultimate customers and in accordance with exact project requirement. In addition to above, we manufacture panels strictly adhering to the relevant IS / IEC standards, electricity rules and other applicable specifications prevalent and as updated from time to time in this respect.

We have also an advantage of getting time to time help and assistance from our associates unit M/s. AMIN MACHINERY PRIVATE LIMITED, an ISO 9001-2000 certified company, who are engaged in manufacturing of welding automation equipment's like Rotators, Positioners, Column & Boom manipulator etc.. in technical collaboration with world famous Mis. F.Bode & Sons Ltd., U.K. It also under takes manufacturing Industrial & Laboratory Sigma Kneder / Mixer machines of immense to use Chemical processing units. It also makes custom build machinery and equipment. All the electrical work for above products like control panel, machine wiring, Installation & testing etc. shall be done by Amin Panels.

We offer premium quality positioners, to move work-piece or weldment in order to position the work-piece. It enables down hand welding to be conducted in whichever position required or possible. There is an alternate to positioner, the work-piece can be moved physically by crane. Positioners reduce the fabrication time by 40%.                  
 
The Conventional Type Positioner - fitted with table rotates through 360 deg and tilt through 135 deg.  There are certain types of Positioners to tilt the table backwards by 45 deg and forwards by 90 deg. The latter tilting range is specifically designed to suit in the fabrication of cladding of certain work-piece.
 
Positioners offered by us are rugged design and are self-supporting, thus they do not need to be fastened to the floor, in order to make these moved by crane from one position to another as and when required. In some exceptional cases, which apply to machines in the 50 T and above capacity range, where center of gravity is high and it is advisable for the machine to be anchored in Positioner.
 
Tables of Positioners are rigidly fabricated. To prevent the table from deflection, underside of the table is provided with stiffeners. The table is stress relieved and precision machined. To assist the clamping of work-piece, the tables are provided with radial slots and concentric rings. It is supported on a heavy shaft, which is fabricated from EN9 steel and rotates on pre-loaded taper roller bearing.
 
To maintain the shaft and bearing in a preloaded condition, the rear of the spindle is threaded with a fine thread and equipped with precision locking nuts.
 
Machines of 5 Tons capacity and above up to 35 tons capacity are provided with imported preloaded cross roll bearings (slewing ring) that in comparison to large diameter ball bearings have no deflection under load. The large diameter bearings provide a more rigid support to the larger tables fitted to the heavy duty machines than is the case with a center shaft. Hence if the work-piece is negligently loaded off center there is less risk of damage to the table than where a center shaft is used.
 
There is another advantage in using slewing (bearings) on the larger machines, since there is no center spindle, a larger diameter hole through the center of the table is provided for services. It is used in gas pre-heating and in many others. 
 
The variable speed table rotation drive is achieved with the help of a thyristor controlled DC motor and suitable reduction gearing. Machines of up to 10 Tons capacity and above are fitted as standard with thyristor table rotation. These offer a speed regulation of ± 1.0% or 0.05% of base speed, depending upon requirements.
 
Positioners with thyristor variable speed rotation drive incorporate the drive arrangement mounted underneath the cross head to support the table. The DC motor is directly connected to the heavy duty reduction gear box, which in turn drives the table through the large spur gear on the periphery of the table thus reducing backlash to a minimum.
