Meraj Engineering

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.

Meraj Engineering two-plane geared roll straightener is capable of feeding and straightening accurately thin walled tubing from 1/4" to 3" O.D 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.

The operation of straightening and other machinery has a critical dependency on the entry & exit equipment to feed the product into the machine and collect it as it comes out on the exit side. The main purpose of this equipment is to safely handle the product and do so without causing damage or marking.

At Meraj Engineering we have extensive archives detailing many different handling equipment schemes which have been used successfully for decades. We assure you that we can provide the best entry & exit handling equipment to straighten a very diverse range of products.

Meraj offers in modern times with technological progress all round, there is a demand from buyers and users of tube for greater degree of straightness and roundness free from markings or ripples. From the view point of manufacturers of tube, the benefits of a well-straightened tube becomes a clearly visible disaster. Hence the straightening process makes the tube either saleable or scrap.

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

Features:

• Machines comprise of six / ten work rolls arranged in pairs.
• Rolls are quickly and easily adjusted angularly to give a perfect contact between the tube and roll over the maximum effective roll profile.
• Setting of the machine for different sizes of tube is simple.
• All rolls are driven by two identical electric motors.
• Machines are fitted with indicators for vertical and angular setting of rolls.
• Accuracy
• Long-life straightening rolls
