Product Details:

These are vertical push-down broaching machines being most simple machines and are commonly used for the hand tool plants for broaching of spanners & wrenches etc., cycle part manufacturers for broaching of various cycle parts and also by electrical and general engineering industries. These machines are available with capacities of 10 to 100 tons, strokes up to 1550 mm and broaching speeds up to 12 m/min.

Product Details:

These Machines have certain advantages over conventional standard vertical internal BMC eve avoiding very deep installation of machines, avoiding of a very high platform for the operator to stand at a very high level to operate the machine and also minimizing the job handling as the machine table is at the workable height.

Description:

• Table-Up Broaching machines are improved automatic versions of Vertical Pull-down and Vertical Surface Broaching Machines with lots of advantages over the conventional machines like no requirement of the pit and/or raised a platform for operator. In these machines the job is placed on the machine table which moves up with the job, the broach remaining stationary, and the operations are carried automatically without any manual handling of jobs and Tools.
• These Broaching machines are available in various versions like Single station and multistation designs including Internal Broaching and Surface Broaching in the capacities of 6 to 200 tons, strokes of 600 to 3000 mm and cutting speeds up to 16 m/min.

Product Details:

Description:

• CNC Table-Up Broaching Machines are an advanced version of Conventional Hydraulic Table-UP Broaching Machine with lots of advantage over Conventional Machines like no need of Hydraulic Power pack and Hydraulic oil. Being Servo Motor Driven, they are highly automation friendly and also the consumption of power is much less.
• These Machines are available in various versions like Single Station and Multistation design including internal & surface Broaching in the capacity up to 45 ton and stroke up to 3000 mm with totally variable cutting speeds as required.

^Description:

• These machines are generally used by the automotive and heavy engineering industry for broaching of external surfaces like the matching surfaces of connecting rod big end, steering racks sector gears, and turbine blades, etc. These machines produced are in standard and table-up versions.
• These Broaching machines are available in different versions like Single station, Multistation and Special Purpose Custom Built-in both types, Horizontal and Vertical. Vertical Surface Broaching Machines are available in either Standard design or in Table-Up design (and even with more than one ram occasionally) in the capacities ranging from 6 to 100 tons, strokes of 600 to 3000 mm and cutting speeds up to 16 m/min. Following are some examples of components broached on the vertical internal pull-down broaching machines:

Product Details:

These are the most common type of machines and about 60% of machines in existence are of this type in the machine the work is placed on top of the table and the broach is pulled through the job. These pull-down machines are capable of holding internal shapes to closer tolerances by means of locating fixtures on top of the work table. These Broaching machines are available in various versions like Single station and multistation designs with options of manual, Semi Automatic and Automatic machines with Winged Automation, in the capacities of 3 to 200 tonnes, strokes of 600 to 3000, and speeds up to 16 m/min. We also offer an Innovative Low® Height Broaching as below. Following are some examples of components broached on the vertical internal pull-down broaching machines:

Product Details:

Horizontal Surface Broaching Machines are available in a wide variety of types for internal broaching, surface broaching and special applications. These can also be provided as tooled-up ready to use machines. These machines are available with the close-grained, high-tensile, one-piece cast iron heavy structure or with continuously welded and thermally stressed relieved fabricated steel structure. Each is designed and constructed to assure the rigidity and stability required for precise tool tracking and uses high-quality parts and components; in the capacity range from 6 tonnes to 100 tonnes, stroke range from 800mm to 3000 mm and cutting speeds up to 16 m/min

Product Details:

These machines are mainly used by the automotive, auto parts manufacturers and defence organizations for broaching of Helical/Spiral serrations, grooves or spline. In these machines, a special broach with spiral successive teeth is pulled or pushed and simultaneously a relative rotary moon is produced to create the spiral pattern. These machines are available in the capacities of 6T to 100T, strokes of 600 to 3000 mm and speeds up to 10 m/min. Some Helical Broaching examples are shown below:

Crane-Bel offers user friendly, simple and highly productive Broaching Machines requiring minimum maintenance and Mending her applications to a wide field of applications. The range includes Vertical pull type, Multi-stadon, Low height, Table-up, Surface broaching, Push down/C-frame type, Horizontal and Pot broaching machines. These machines are available In a wide range of capacities ranging from 3 tonnes to 75 tonnes and strokes ranging from 600 mm to 2500 mm.

Product Details:

Description:

• These are high output production machines, specifically suitable for surface broaching and open ended broaching operations in small components like door fings, cylinder locks automobile locks and many other components where very high accuracies and very tight tolerances are not required and the productivity is main criteria. The key to the productivity of these machines is that the components continuously pass through the broach tool and there is no return stroke, hence the cycle me is very short, perming very high production rate.
• Crane-Bel continuous chain-broaching machines have rigid horizontal frame with special design slides and guides and unique carrier and cars to offer the challenging production rates.

In the age of global competition, there is more attention towards the automation by way of machining centres and multi-function Turning centres. Broaching has the positive advantages like high productivity and repeatable product quality.

Productivity improvement to ten times or even more is not uncommon, as the speed of metal removal by broaching is vastly greater. Roughing, Semi finishing and finishing of the component is done just in one pass by broaching, and this pass is generally accomplished in seconds. Thus Broaching has proved to be a most simple, highly productive cost effective and practical machining operation. It requires lesser manpower, extending its use in wide fields of applications with exceptional savings on machine and tooling cost.

Broaching is highly productive Metal Cutting Process, in which the metal is removed by successive action of number of cutting teeth incorporated in the tool called Broach.

Broaching is a significantly superior process having certain positive advantages like:

• Short Cycle Time with High Accuracy.
• Complicated irregular shapes can be easily cut.
• Remarkably Stable Process Accuracy.
• Superior Finished Faces.
• Extremely Economical.

Crane-Bel Broaching machinery have earned an outstanding reputation for their productivity, reliability and economy. This reputation has been won by their unrivalled design, quality and manufacturing technology based on long experience in the field and strenuous efforts to offer a distinguished Broaching machine to the industry.
