Let’s discuss the question: how to machine splines on a shaft. We summarize all relevant answers in section Q&A of website Activegaliano.org in category: Blog Marketing. See more related questions in the comments below.
How is a spline machined?
The splines are cut into the shaft by a process called straddle milling. The indexing fixture holds the shaft of the spline steady while a groove is cut by the rotating milling cutters along its length. Depending on the depth of the spline, multiple passes along the same groove may be needed.
What machine is used to cut splines?
A milling cutter with a reverse form of the involute is used to machine involute splines. The last method is called shaping which is used to make both internal and external splines. Both the cutter and workpiece roll together with the cutter removing the material from the workpiece when in down stroking action.

How spline shafts are made?
Metal spline shafts are formed through either hot rolling or cold rolling. Both processes use pressure to roll and shape the metal into the form required for the specific spline design. However hot rolling uses high temperatures to help form the metal and creates a product with greater workability and formability.
What is the difference between a spline and a gear?
Splines and gears are both purposed to transmit torque and both feature external teeth that lock into place with a mating component. Splined shafts differ from gears as they use all teeth or grooves simultaneously to transfer torque. Gears in contrast, utilize one tooth at a time to transfer torque.
What is an involute spline?
A spline is a set of narrow generated longitudinally around the circumference of a shaft or grooves generated on the inside bore of a workpiece. The externally splined shaft mates with an internal spline that slots, or spaces, formed in the reverse of the shaft’s teeth.
Which method is used to cut teeth on gear cut splines on shaft flutes on drill?
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 of the gear are progressively cut into the material (a flat, cylindrical piece of metal) by a series of cuts made by a cutting tool called a hob.
Which method is used to cut teeth on gear?
The most common gear-cutting processes include hobbing, broaching, milling, and grinding. Such cutting operations may occur either after or instead of forming processes such as forging, extruding, investment casting, or sand casting.
Can Moser axles be shortened?
All popular bearing sizes and bolt pattern combinations are available. If your future plans call for a narrower rear, Moser Custom Alloy Axles can be shortened and resplined to fit your needs and bolt pattern changes can also be made.
Which type of side and face cutter has the teeth on one side only?
A plain side milling cutter has teeth on both sides and on the periphery. When teeth are added to one side only, the cutter is called a half-side milling cutter and is identified as being either a right-hand or left-hand cutter. Side milling cutters are generally used for slotting and straddle milling.
What are the types of splines?
- (1) Parallel: Parallel spline shaft would have ridges or teeth that have a square profile.
- (2) Involute: This kind has tapered ridges along the shaft, which help in lowering the stress concentrations during gear operation.
- (3) Crowned: …
- (4) Serrations: …
- (5) Helical:

What is a helical spline?
A helical spline broach — also known as a spiral broach or continuous engagement broach — is a type of broach that creates an internal spiral in a pre-drilled hole. Several applications use helical spline broaches, including automotive transmission and firearms manufacturing.
What is spline cutting?
Spline cutting is the process of machining internal or external splines (ridges or teeth) onto shafts, gears and other mechanical power transmission components, which mesh with grooves in a mating piece allowing power to be transmitted from one to the other.
Are splines interchangeable with gears?
A splined shaft can come with square-sided or triangular splines, while the teeth of a gear can have curves. Because of this, the usage of splined shafts and gears are not always interchangeable.
What are axle splines?
The spline of an axle is the teeth or peak that are machined on the end of the axle and mesh with the differential or spool inside the pumpkin of the rearend.
How are splines measured?
Typical involute SAE/ANSI spline teeth are specifies as two numbers: a numerator that specifies the tooth thickness in diametral pitch (DP) and the second number that specified the tooth height in diametral pitch (DP). Thus an 8/16 spline has the tooth thickness of 8 DP and a tooth height (whole depth) of 16 DP.
How do you create involute splines?
Calculate involute spline
On the Design tab, click the arrow next to the Splines Type edit field to select the spline and enter the spline dimensions. Switch to the Calculation tab. Select the method and type of strength calculation. Enter the calculation values.
How do you get a spline module?
a spline for a 50mm OD spline with say a module of 2mm would have a PCD (D) of 50 – 2 = 48mm. The number of teeth = D/m and as an whole number of teeth is required a value of D = 48mm is easily selected with number of teeth z =24 teeth.
What is a spline pressure angle?
The pressure angle of a spline is the angle between where the pitch diameter meets the involute curve and a tangent point on the base diameter (fig. 4). There are three major pressure angles used in the spline rolling industry today. These angles are 30, 37.5 and 45 degrees.
How does a gear hobbing machine work?
Gear-hobbing machines use a rotating, multiple-tooth cutting tool called a hob for generating teeth on spur gears, worm gears, helical gears, splines, and sprockets. More gears are cut by hobbing than by other methods because the hobbing cutter cuts continuously and produces accurate gears at…

Who invented hobbing machine?
Various other patents followed until 1897 when Herman Pfauter of Germany invented the first hobbing machine capable of cutting both spur and helical gears. Through the 20th century, various types of machines developed.
