Major Functions of the Machine Tool

GP6020 semi-automatic spline shaft milling machine is designed to process straight-slot long spline shaft through hobbing. It can also be used to process straight gear shaft.

Major Performance and Structural Features of the Machine Tool

This machine, by applying electrical hydraulic control, could realize semi-automatic one-time work cycle, automatically completing the following action: Rapid approaching of milling head; vertical cutting of the slide; rapid return of the milling head; rapid return of the slide

The machine has a mechanism that could eliminate the gap between feed screws and nuts, and perform hydraulic control against tensioned workpiece at down milling tailstock

1. Lathe Bed

The lathe bed is a rectangular box with sufficient rigidity. On the left side of the bed locate the electrical box, the main motor and the fast motor. On the right side of the bed locates the hydraulic control equipment. The cooling pump motor and coolant tank are located in the middle of the hydraulic oil bath.

2. Lathe Head

The lathe head is equipped with the components of the index feed rapid transmission mechanism. Open the rear door of the lathe head, there is the exchange hanging wheel for milling cuter speed indexing and feeding. Its major function is to transmit the indexing movement to workpiece supporting workpiece, transmit the feeding movement to the feed screw and transmit the milling cutter rotary movement to the feed rod.

Understanding Splines:

A spline is essentially a shaft featuring a series of teeth that match the spaces of a corresponding shaft. This unique design allows for the efficient transfer of rotational movement and force along the same axis, dictated by the designed form and fit. Splines can be either external or internal, offering versatility in their applications and tooth shapes.

The Hobbing Process:

In the realm of splines, teeth are generated through the hobbing process. Using a specialized cutting tool known as a hob, teeth are produced as the hob turns in synchronicity with the workpiece. This simultaneous cutting of flats along the tooth profile ensures the productive generation of multiple teeth, optimizing efficiency.

Internal Splines:

Internal splines are produced using methods similar to internal gear production, including shaping, form-milling, or power-skiving. Additionally, due to their straight-toothed nature, internal splines are often efficiently broached for production.

External Splines:

For external splines, tooth profiles can be cut using various methods such as shaping, hobbing, form-milling, or power-skiving. Hobbing, in particular, strikes a balance between productivity and flexibility. Shaping methods are also employed, especially in applications with sweepout clearances and tight part features.

Spline Fits:

The design of an involute spline can be tailored to major diameter fits or side fits by adjusting the depth of the hobbing cut. Major diameter fits control the fit by varying the major diameter of external teeth, while side fits, which are self-centering, control the fit by varying the tooth thickness. This helps equalize stresses at the bearings of all teeth.

Spline Forms:

Side-fit involute splines may take a flat-root or fillet-root form. A flat-root spline hob generates a chamfer on the tooth to provide clearance at the major diameter, while a fillet-root spline hob features a smooth radius, avoiding a hard chamfer on the spline teeth tips.
