Wide experience has enabled us to offer newly designed 'NE' series machines. These machines are equipped with compact geared type feeding system. Thousands of our 'N series machines are satisfactorily working in our country as well as abroad. Like our earlier 'N' series machines, these machines are capable of producing different types of nail heads and points.

OPERATION:
The wire form wire coil passes through straightening rolls and fed intermittently into the gripping dies which close firmly head of the nail. The grip is loosened now and the required length of wire is fed forward. Then the cutting tools cut the point a little forward of the grip leaving sufficient wire projecting to form the head of the next nail. This sequence of operations is repeated at each revolutions of the machines and the nails are produced constantly.

CONSTRUCTION:
The frame of the machine is extremely rigid, all moving parts are of ample dimensions and precisely made from quality material under strict quality control, which ensures the smooth running of machine in spite of high rate of output.

DRIVE:
Keeping in view to-day's technology, our machines are equipped with well proven 3 shaft system. The main shaft controls Heading, while two side shafts control Grapping, Cutting operations and nail length operation, through gears, which ensures the accident-free motions.

WIRE FEED:
The wire is feed through connecting-rod. The setting of the desired length obtained quickly and easily.

PHOSPHORUS BRONZE:
The bush are made from Phosphorus Bronze and are of ample dimensions. While manufacturing, care has been taken and provided with continuous approach of oil which ensures the smooth running and long life.

Phosphorus Bronze containing Copper - 87 % , Tin - 12 % & Remaning Others etc. which ensures the smooth running and long lasting.

TOOLS:
The setting of the machine is made very easy and less time consuming; even unskilled operators are able to handle the machines without difficulty after a short time observation. Their special feature is round type Gripping dies which gives 8/10 times the service of common flat dies normally used in similar machines.

CRANK SHAFTS:
The main crank is counter-balanced and runs in 4 bush in oil bath chamber. Even smooth running and equal distribution of loads ensure long life.

LUBRICATION:
The bevel gears and the crank shafts are totally enclosed in oil chamber and require no attention, except periodical checks.

Due to policy of continuous improvements, we reserve the right to alter or amend the design of machine without prior notice.

POLISHING BARREL

Wire Nails are produced by wire Nail Making Machines. The Nails are to be polished as well finished products. The quality of the Nails produced depends upon the wire used on the Machine. Generally, the wire received from the supplier is found dull due to Wire Drawing process and also some times gets rested due to weather effects. The wire for process of cutting Nails is not so bright as a result, the Nails produced do not have brightness and shining. Such finishes are never acceptable to the buyers. Thus, the Nails do require polishing which results in an attractive finished products.

To overcome this difficulty, the machine known as Polishing Barrel has been devised. The polishing barrels are available in three size viz. 500 kgs. , 1000 kgs. and 1500 kgs. Capacities per charge.

INSTRUCTIONS :

1) Load the polishing barrel with wire nails 3 to 4 inches above the half size of the barrel and remaining portion with Saw Dust. If the Nails are found rusty, it is advisable to Mix a little quantity of paraffin oil (Half liter Kerosene) prior to loading of Saw Dust. Rotate the barrel with blind lid on, for about 10 minutes. After this process, load the barrel with Saw Dust and rotate the barrel for about 30 minutes fixing blind lid-take out blind lid and fix up perforated lid to take out Saw Dust from the barrel by rotating. Continue this process again for about 40 minutes loading the barrel with fresh saw dust. This will result into bright shining look of Wire Nails. The Saw Dust used in second sequence can be re-used for the first cycle of the same process in next batch. This ensures economy of Saw Dust and solving the storage space.

2) If the mirror finish is required on the Nails, it is advisable to use SOFT LEATHER PIECES in second sequence of polishing instead of Saw Dust, 15 to 20 kgs. of such LEATHER PIECES are required for out 500 kgs. Capacity Polishing Barrel. These LEATHER PIECES can be applied again and again for about 15 to 20 cycles till they become very oily.

TOOL GRINDER

The Cutter tools of the Nail Making Machine become blunt and they require re-grinding. We have developed a special Cutter Grinder for grinding all the profiles of cutters. These machines are provided with special type jigs fixtures and even semi-skilled worker can grind (re-sharpen) the cutting tools easily after brief training. It takes only few minutes to grind the cutting edges of the cutting tools
