Machineries

• Power feed for the X and Y axis with digital power controller results in efficient milling operation and consistent fine surface finish.
• The Machines can be modular and extendable, so can be modified and used according to available space constraints.
• The use of pneumatic and hydraulic drives for the milling head results in high spindle torque for milling at the same time keeping the weight at the operating point to a minimum.
• A combination of high-powered hydraulic drives and heavy-duty spindles helps in the rapid milling of surfaces.
• The machine can be made to specific requirements with additional provisions like tilting facility to required angle, grinding head, drilling attachment, etc

Types of portable milling machines:

1. Linear milling machine

Linear Milling Machines have one longitudinal guideway with a cross slide of limited stroke and tool feed on Z-axis

Longitudinal Stroke length - 500mm to 3000mm

Cross Slide stroke length - 200mm

Z-axis tool feed - 150mm

2. Gantry type milling machine

Gantry-type milling machines have two guideways for longitudinal travel and a crossway between the two longitudinal guideways on which the milling head moves during operation. Travel along the X, Y, Z axis can be configured to specific requirements.

Machines can be made according to customer requirements from 1000mmX500mm to 20000mmX6000mm

Options of power feed and Servo controls for X, Y, and Z- axes are available.

• Our grinding technology and tools are not only user-friendly but also are capable of grinding the crank shaft to close dimensional and geometric tolerance.
• Our grinding tools are portable and can be easily carried by technicians to the site whether it is a remote power plant or a ship stranded in mid-sea.
• In addition to the grinding tool, machining attachment can also be used for machining of crankshaft according to situation and requirement. In cases where the material removal is high, a machining attachment can be used to bring down the repair time.
• Training form an integral part of the Product. Training for on-site removal of bend in the crankshaft and the use of Non-destructive testing equipment in the inspection of Crankshaft is provided.

• The hydraulic motor and power pack gives smooth drive power with high torque over a wide range of speed. This is ideal requirement for difficult cutting conditions where the hardness of the material or condition of damage makes it impossible to set a high speed. The even power given throughout the operation by the hydraulic power pack helps in getting a very fine surface finish.
• More importantly at the point of drive, that is at the driven end of the boring spindle, the weight is very less when compared to direct electric drive. As the power pack is provided with heat exchanger it can be continuously run for longer periods.
• The different type and range of fixture provided with the machine helps in setting up the machine according to site requirements.  Even an intentional offset can be made to the centerline as per the requirement of situation and application. In case of boring operation where alignment of bore are not under close tolerance a simple centering fixture can be used.
• The Feed unit and tool holder of the machine are unique and helps in achieving close control of operation, accuracy and surface finish.
• The feed unit for the line-boring machine is a special type, which can be used for manual feed as well as auto-feed. The feed unit is capable of giving very fine feeds which help in attaining very fine surface finish. Another important feature of the feed unit is that the feed length is not restricted with the feed unit length.
