Straightening Machine

Metal Stock, such as wire, rods, bars, profile and tubes, is formed by rolling, drawing and otherwise shaping the metal both while it is a relevant temperature and after it has cooled. The metal stock cools and cures in a heterogeneous manner such that a degree of warpage and curvature typically develops in the stock. In the prior art, the stock has been straightened in machine known as metal stock straighteners.


Cross Roll Tube Straightening Machine

Meraj multi-cross-roll straightening machine allows the tube to be rounded straight during straightening.

The Meraj multi-cross-roll tube straightening machines provide all the advantage and meet the requirement of modern industries. Meraj offers two types of straightening machine with 6 roll and 10 roll design respectively, each of which meets a particular requirement of straightness tolerance.

The 6 roll tube straightening machine caters to straightening tolerance of 1mm in 1 Mtr length and the 10 roll tube straightening machine caters to straightening tolerance upto 1mm in 5 Mtr lengths depending on material specifications

Bar / Rod Reeling Machine

Precision round bar straightening & polishing machines manufactured by Meraj Engineering are of the “two roll, adjustable angle” type.

These machines are recognized for the potential to precisely straighten ferrous and non-ferrous round bars.

All machines are supplied with Automatic (hydraulic), Semi-Automatic & Manually operated system which prevents damage to the rolls or machine structure. This feature allows the operator to pre-set the load that is applied to the bar is it passes through the machine.

The mechanical design of each model of the machines is suitable for heavy duty applications.

With their extensive knowledge of metal straightening, our engineers are able to solve the majority of round bar straightening problems.

Parallel Roll Tube & Rod Straightening Machine

Meraj Engineering two-plane geared roll straightener is capable of feeding and straightening accurately thin walled tubing from 1X4" to 5" OD X 1mm wall.

Power driven feed rolls advance the tube or bar stock through two sets of rolls, eight rolls to a plane.

The tube does not rotate during passage, thus eliminating stock damage such as spiraled burrs, or operator injury due to rotating tubes.

Rolls are designed for each particular requirement. They may be supplied for square or hexagon as well as round. Drive roll spindles are mounted on Timken bearings. The idler rolls rotate on needle bearings.

Gear boxes are totally enclosed with hardened steel gears bathing in oil.

Meraj Engineering Machines can be built for a speed range to meet the customer's requirements. Feed roll speed is controlled using an inverter duty motor and an engineered AC Inverter Drive.

The roll housings are mounted on a welded steel base. Centerline may be altered to meet customer specifications

Material for Straightening: ferrous and non-ferrous metals such as copper & copper alloy, brass, aluminium, ss, ms etc.
