Overview
Product Overview
The Vertical Broaching Machine Pull Type is a hydraulic production machine designed to pull a broach vertically through a supported workpiece. Its upright arrangement provides a compact floor footprint and controlled alignment for machining suitable internal forms.
Available configurations cover a listed maximum pulling-force range of 3,000 to 25,000 kg and stroke range of 400 to 2,000 mm. Work-table sizes range from 400 x 400 to 600 x 600 mm, with table bores from 80 to 200 mm to suit different workpieces and tooling arrangements.
The hydraulic system provides cutting speeds from 2 to 5 m/min and return speeds from 15 to 20 m/min. Supported broach data includes shank diameters from 12 to 63 mm and broach lengths from 500 to 1,600 mm, with listed loader strokes from 800 to 1,200 mm.
Typical applications include producing keyways, splines, slots, polygonal bores and other internal profiles in suitable components. Final machine selection should be based on the component drawing, work material, profile, stock allowance, broach design, required force and stroke, production rate, fixture arrangement and surface-finish requirement.

FAQs
Frequently Asked Questions
What is a vertical pull-type broaching machine used for?
It pulls a broach vertically through a supported workpiece to produce suitable internal profiles such as keyways, splines, slots and shaped bores.
What pulling-force range is available?
The supplied specification lists maximum pulling-force configurations from 3,000 to 25,000 kg. The required capacity must be calculated for the work material, profile and broach design.
What is the available stroke range?
The listed maximum stroke range is 400 to 2,000 mm, depending on the selected machine configuration.
What broach sizes are supported?
The source lists broach shank diameters from 12 to 63 mm and broach lengths from 500 to 1,600 mm. Compatibility must also be checked against puller, stroke and force requirements.
What are the cutting and return speeds?
The hydraulic cutting speed is listed as 2 to 5 m/min, while the return speed is listed as 15 to 20 m/min.
What work-table sizes are available?
The listed work-table range is 400 x 400 to 600 x 600 mm, with table bore options from 80 to 200 mm.
Are fixtures and broaches supplied with the machine?
Tooling and fixture scope should be confirmed for the order. Broaches, pullers and fixtures normally need to match the component drawing, material and production requirements.
What information is required for machine selection?
Provide the component drawing, material, profile dimensions and tolerances, stock allowance, broach details, production quantity, required cycle time, fixture concept and available electrical supply.
