ROLLING
Source document graphic
Shaft/spline rolling is one of the most popular and economical manufacturing processes for creating an involute tooth form.
This cold forming process offers many advantages in the manufacture of automotive and power transmission shafts, motor shafts, pump shafts, axles and other parts where there is a need to transmit torque.
Rolling is the preferred method for producing strong, smooth, precise, and uniform external thread. Thread rolling is different from other types of threading processes like cutting, grinding, and chasing.
Rolled threads have improved physical characteristics, greater accuracy and a high degree of surface finish. They are uniformly produced at high rates of production with no wasting of material.
Advantages of thread rolling are material savings, improved surface finish, better fatigue and ultimate strength, and above all economy of manufacture. Savings of 75% of threading time are common when thread rolling replaces hobbing, milling, and die head threading. Even greater savings result when rolling replace thread grinding and single point threading. Also, rolled parts are more efficient and run smoother and quieter than cut-thread parts because of their superior surface finish.
Advantages of rolling:
Higher precision-Accuracy of the tread profile is excellent
Higher quality of surface finish
Superior wear resistance against deformation of the contact surface – reducing friction, allowing less working effort as well as reduced motor absorption.
Increased resistance to corrosion.
Greater resistance to fatigue
Quieter motor & reducer operation.
Production time & cost less than other methods

GRINDING
Source document graphic
Grinding is a machining process that uses abrasive cutting to remove material from a workpiece. Gear grinding is the process of finish grinding gear teeth and is a critical step when manufacturing high precision gearing. Gears with precision ground teeth run more quietly and wear more evenly than gears with cut teeth.
It is widely known to be the most accurate way to finish a high precision gear, offering a more precise tooth finish than gear cutting.
They can also handle higher loads and are useful when large amounts of torque are required. For these reasons, they are often found in types of equipment that demands high performance and reliability.
Our gear grinder includes the latest technology including CNC control, integrated grinding wheel dressing, onboard gear measurement, power dressing, double flank anti-twist grinding, adaptive grinding and Opti-Grind.
We have all measurement instruments to control the shapes, roundness, cylindricity, concentricity, straightness, roughness...

MILLING - WHIRLING
Source document graphic
Source document graphic
Source document graphic
Thread Whirling is a form of the Thread Milling process with the exception that the cutters are mounted on the inside of a Cutting Ring or Cutter Holder rather than the outside of a milling tool.
Planetary milling (whirling process) is a machining process in which is multi-point rotary tooltips (cutters) removes material by passing over the rotating workpiece and advancing at the lead to produce a helical form. ... Threads of a worm are generated as a result of the tool holder rotating at high speed around a slowly rotating workpiece. Whirling is a fast method of producing worms.
Our state-of-art manufacturing unit and the usage of contemporary techniques, we can present a comprehensive range of Milling Machines of the Shaft. Keeping in mind the latest market development, this shaft is perfectly manufactured by our diligent engineers employing quality assured raw material with the help of cutting-edge techniques as per the defined industry standards.
Advantage of whirling:
Increased productivity due to prolonged tool life and quick tool changeovers
Superior surface finish
Burr-free threads

TURNING
Source document graphic
Source document graphic
Source document graphic
Turning is a machining process in which a cutting tool, typically a non-rotary tool bit, describes a helix toolpath by moving more or less linearly while the workpiece rotates. When turning, the workpiece (as metal) is rotated and a cutting tool is traversed along 1, 2, or 3 axes of motion to produce precise diameters and depths. Turning can be either on the outside of the cylinder or on the inside (also known as boring) to produce tubular components to various geometries. Although now quite rare, early lathes could even be used to produce complex geometric figures, even the platonic solids; although since the advent of CNC it has become unusual to use non-computerized toolpath control for this purpose.
The turning processes are typically carried out on a lathe, considered to be the oldest machine tools, and can be of four different types such as straight turning, taper turning, profiling or external grooving. Those types of turning processes can produce various shapes of materials such as straight, conical, curved, or grooved workpiece. In general, turning uses simple single-point cutting tools. Each group of workpiece materials has an optimum set of tools angles which have been developed through the years.

HOBBING
Source document graphic
Hobbing is a machining process for gear cutting, cutting splines, and cutting sprockets on a hobbing machine, which is a special type of milling machine. The teeth or splines are progressively cut into the workpiece by a series of cuts made by a cutting tool called a hob.
The main advantage of the method is the higher production rate of the gears.
Compared to other gear forming processes it is relatively inexpensive but still quite accurate, thus it is used for a broad range of parts and quantities. It is the most widely used gear cutting process for creating spur and helical gears and more gears are cut by hobbing than any other process as it is relatively quick and inexpensive. A type of skiving that is analogous to the hobbing of external gears can be applied to the cutting of internal gears, which are skived with a rotary cutter (rather than shaped or broached).
