Cold Cut off System

The Cold Saw is an essential part of our tube mill, which enables cutting of the tube to the preset length with no burr. Its function determines the overall productivity.

The Cold Saw Cut-off system can easily handle all types of tube profile - circular, square and rectangular. The synchronization is achieved with the use of AC Servo motor control system for fastest response time and best results. This is an online milling operation.

An HSS blade at controlled rpm and feed goes through the properly clamped tube without any heat or spark generation as all the heat gets transferred to the chips. This process called cold cutting, results in clean cutting of the end without the need for any end facing or de-chipping even the hollow section. It is the most modern technology in flying cut offs across the world. The machine is totally Numeric Controlled and highly user friendly.

Details of the Equipment

 

This equipment consists of a steel fabricated track fitted with solid machined alloy steel rail for smooth vibration free running of trolley.
The trolley is a steel fabricated structure - rigid but light weight, fitted with antifriction heavy duty bearings.
Cutting arm and clamping assemblies are hydraulically operated, vibration free and have rigid design.
The trolley Drive is through Rack & Pinion made of alloy steel material duly hardened for long life trouble free operation. The pinion is driven through an imported AC Servo Motor with in built zero back lash planetary gear box
Blade drive is through 15HP AC Motor through a Zero back lash helical reduction Gear Box, specially designed in compact form for Cold Sawing application.
The Saw Blade is made of coated HSS material with special tooth profile for cold sawing application.
The complete equipment can be designed to suit your existing mill.

 

Rollform has enjoyed the distinction of being the largest supplier of Cut �offs in India.
