We manufacture and supply a wide range of welding rotators, which are extensively used in heavy and light fabrication shop. Welding rotators are used to rotate or position the cylindrical jobs for circumferential welding (tig / mig / sub arc) or for intricate assemblies. It incorporates ino drive unit and ino idler unit and control panel with pendant. It is equipped with ac frequency variable drive that is used for stepless speed variation. The rollers in the machine are made as per the customers requirement, either made of steel or moulded with polyurethane. These welding rotators find applications in welding of pipes, api pipes, boilers, heat exchangers, pressure vessels, mounted vessels, lpg bullets, barrels and tanks. They are sometimes called are useful accessories in welding fabrication workshops, designed to keep in place and to rotate heavy cylindrical parts around a horizontal axis, at a constant and steady turning speed in front of a welding head. Alternatively they may be rotated in steps until a needed position is reached, and then locked in place for making a longitudinal weld with a welding head mounted on a traveling carriage. Turning rolls permit to perform circumferential welds in a vertical plane. They are also used for surfacing (cladding), or depositing by welding a filler metal of useful properties on the external or on the internal surface of a hollow cylinder. turning rolls are usually arranged in sets including a pair of identical rolls, one of which is rotated by an electric motor through a reduction gear box, known at the powered or drive unit while the other is idle, so arranged that the distance between the rolls can be adjusted to accommodate cylinders of different diameters, and mounted on a fabricated frame of simple shape. Usually a pair of such frames must be arranged on the shop floor at some distance from one another, to accept the cylindrical body in need of welding.

We offer welding positioners we essentially manufacture five types of welding positioners – 1.standard welding positioners: positioners ranging from our standard range of 50kg to 30,000kg, larger capacities and special requirements can be manufactured to suit customer’s specific requirements. The primary function of positioning range of machines is to assist the welding operator to rotate the work piece through 360° to reposition the component for inspection or welding. a positioner gives the added advantage of a tilting function to tilt the work piece from horizontal to vertical to better position the component for down hand and automatic welding. Low load positioner is ideal for rotating and tilting lightweight work pieces.  the speed is step less adjustable.  low voltage foot pedal with start/stop function. For daily work, these positioners offer perfect solutions.  the positioner have 2-axis( rotating & tilting)  200kg positioner have manual tilting adjustment while 500kg, 750kg and 1000kg positioner have motorized tilting.  the 2-axis operation guarantees the ideal ergonomic working position.  mechanically and electrically the positioners have been designed for easier maintenance and a small number of spare parts as well.  200kg, 500kg, 750kg and 1000kg positioner are available in llp range. We also supply higher capacities as per customers requirement. 2. Elevating welding positioners: the primary function of it is to assist the welding operator to rotate the work piece through 360° to reposition the component for inspection or welding. a positioner gives the added advantage of a tilting function to tilt the work piece from horizontal, to vertical to better position the component for down hand and automatic welding. The added advantage of the elevating machine is to enable large and odd shaped components to be raised and elevated whilst being rotated and tilted to reposition the component to the correct position prior to welding. 3. Rotilt type welding positioners: ro-tilt type positioners ranging from our standard capacities of 500kg &1,000kg. Larger capacities and special requirements can be manufactured to suit customer’s specific requirements. The advantage of using a ro-tilt type positioners is that it allows the operator to tilt the work piece through 360 degrees. This type of equipment offers the welder greater maneuverability of the work piece by rotating and tilting it into the best possible position, before the welder carries out his work. We offer the option of a fully manual operation, fully motorized option, or a combination of manual and motorized rotation and tilt functions. cnc control can also be provided. 4. 5 – axis positioner: our 5-axis positioner provides ergonomically friendly positioner height. This positioner gives the flexibility to rotate your work, providing access to reach difficult areas. Features:  high capacity dual positioners are rated at 750 kg / maximum load offset of 90 mm (3.5 inches)  turntable exchange axis vs. Free wheel style exchange axis eliminates labour platforms, material platforms, and platform fencing  suited to longer parts such as final exhaust assemblies  tilting axis allows complex geometries to be welded in 1f position  positioner base is angled to provide ergonomic load height  heavy duty table support  innovative center axis drive arrangement  controls solutions available

We offer cnc router for wood, stone, plastic and fibre boards. Routers are usually associated with carpentry, which is why cnc routers are usually associated with woodworking only. However, there are many other materials that can be cut. so, if your answer to question one was any of the following: wood particle board plastic foam composites glass aluminum* stone then it is safe to assume that a router could still be the machine for you products desktop cnc routers - 2 ft x 2 ft - 2 ft x 3 ft - 2ft x 4ft large platform single spindle cnc routers - 4 ft x 4 ft - 4 ft x 8 ft - 5 ft x 10 ft automatic tool change cnc routers desktop toolchange machines - large platform toolchange machines

We are offering cnc plasma cutting machines - unique digital height control reliably controls the height of the torch. - precision servo motors utilize optical encoder feedback for closed-loop operation. - closed-loop servo controller achieves superior accuracy, speed and acceleration (compared to open-loop controllers, such as stepper motor drives), providing perfect positioning even in demanding conditions. - all speeds are adjustable during operation. - automated cutting machine can automatically slow down when cutting around corners and holes. - for maximum accuracy, the gantry is synchronously driven at both ends. - moving parts are rigid, without excessive weight. This enhances performance providing fine, detailed cutting and high productivity through fast cut speeds. - rugged cnc plasma cutting machine with strong drive train is built to perform in heavy production. Drive train and electronics are protected from plasma dust, and guide rollers move unobstructed. - durable steel frame with integral cutting grate. (we loaded up a machine with over 10,000 pounds of metal and couldn't make it collapse!) - cutting grate precisely aligns to the frame, with stops that perfectly position material for indexing and utilizing sheet edges in long parts. - wide plasma cutting torch compatibility with a simple, easy-to-install interface. Works with common hand torch (machine torch not needed). - includes specialized plasmacam design and control
