As spline shafting suppliers, we can manufacture a spline shaft with an outer diameter of 0.25″ to 18″, and a length of 0.50″ to 48″. Module measurements range from 0.5 module to 12 module.
AmTech's shafting manufacturing capabilities include the production of spline shafts for axles, power transmission, gearboxes and other motion control applications. Automated CNC machines give our manufacturing team the versatility to machine or cold form splines. We have extensive experience with meeting the most challenging shape dimensions and tight tolerances.
Our quality raw materials such as carbon steel, alloy steel, stainless, bronze, aluminum and competitive pricing provide the best value in today's market.
To assure that a spline achieves a proper fit, we request that gaging be included in the budget presented to us. We also recommend full complement gaging for involute splines, especially in difficult to reach splines and harder grades of material. The alternative requires measurement between wires, which frequently is impractical.
For small lot quantities and reverse-engineering solutions where gaging may not be practical, the mating part, either male or female, can be used as the standard. Otherwise, we would have to consider making both parts and researching and developing different possibilities.
Shaping and broaching are two of the most efficient methods to produce keyways and internal splines. Maintaining the tight tolerances is one of the most critical factors when performing keyway shaping and broaching services. Our manufacturing facility is well-equipped to handle all types of customer specific requirements.
For shaping, we can cut a width from 1/16″ to 3/8″, with a depth of 0.032″ to 0.5″ and a length up to 6″. If the customer chooses our broaching service, we offer a width capacity from 0.063″ up to 1″, with a depth from 0.031″ to 0.5″ and a maximum length of 5″.
Internal straight-sided spline shafts may require manufacturing either by broaching or by shaping. Broaching is generally the best solution, depending on the quantity and length/size of spline. Shaping can be more costly since it normally requires fabrication of a special cutter, or a single cutter to feed and index each slot.
External straight-sided splines require a specially designed hob in order to produce the proper key and root width.
Advantages of rolled threads and splines in shaft manufacturing:
- Best suited for high volume production
- Economical
- Improved surface finish
- Versatile
- Rolled splines are stronger than machine cut splines
- Increased strength and durability
