Helical
Broaches

Yes, Super Tools manufactures helical broaches fully customized as per customer drawings and specifications. Broaches are designed based on required helix angle, spline or serration profile, material, tolerance, and application needs. This ensures accurate fit, smooth cutting performance, and reliable results for automotive and industrial components. 

Key specifications include helix angle, module or DP, number of teeth, tooth rise per pitch, broach length, and tolerance class. Material selection such as HSS, PM-HSS, or carbide impacts performance and durability. Cutting direction and load distribution are carefully engineered. These parameters ensure stable cutting and consistent profile accuracy. 

Yes, helical broaches are highly suitable for high-volume production due to their smooth, progressive cutting action. They offer consistent accuracy, excellent surface finish, and long tool life across repeated cycles. This makes them ideal for mass production of automotive, transmission, and precision industrial components. 

• Yes, helical broaches generally provide a better surface finish than straight broaches.
• The helical cutting action spreads the load across multiple teeth, reducing chatter and cutting forces.
• This results in smoother finishes, improved profile accuracy, and longer tool life.

Proper alignment and rigid fixturing are essential during installation to maintain profile accuracy. Regular inspection and correct lubrication help extend tool life. Helical broaches can be re-sharpened multiple times while maintaining geometry. Professional regrinding and recoating services are recommended. 

Helical broaches are typically used on vertical or horizontal broaching machines. Machines must provide adequate stroke length, pull force, and alignment accuracy. CNC broaching machines can also be used for controlled operations. Proper machine selection ensures safe and efficient broaching. 

Yes, helical broaches are highly suitable for high-volume and mass production. Their single-stroke operation ensures consistent cycle times. Long tool life and repeatable accuracy reduce downtime. This makes them ideal for automotive and industrial manufacturing. 

Cutting load depends on material hardness, tooth rise, helix angle, and cutting length. Machine rigidity and lubrication also influence load distribution. Optimized geometry ensures balanced forces. This prevents premature wear and distortion.
