Working Principle of Swiss Type CNC Lathe

The Perfect Combination of Structural Innovation and Extreme Precision

What is Swiss Type CNC Lathe (Swiss Lathe)?

Swiss Lathe, also known as Sliding Headstock Lathe, is a kind of CNC equipment specialized in processing small-diameter, high-precision parts. It was first used in the Swiss watch industry and was born out of the need for extreme precision in miniature parts. Nowadays, the equipment has been widely used in medical devices, aerospace, electronic communications, automotive parts and other fields.

 The structural differences with the traditional CNC lathe

1. Spindle and guide sleeve structure

Traditional CNC lathe: the workpiece is fixed in the chuck, the spindle rotates, the tool moves along a number of axes for cutting, and the position of the workpiece itself does not move.

Swiss-type lathe: the spindle drives the workpiece to move axially and provides strong support through the synchronized guide bushings, so that the tool can be machined at the very near end of the workpiece, effectively avoiding jerks and oscillation. 2.

2. Tool Layout

Swiss type lathe adopts multi-axis tool arrangement structure, equipped with main tool row, sub-tool row and back machining tool, which can carry out turning, milling, drilling and other processes at the same time, and greatly improve the machining efficiency.

The role of synchronous guide sleeve

Synchronous guide sleeve is one of the core components of the Swiss-type lathe, and its main roles include:

Provide strong support: there is a guide sleeve next to the cutting area of the workpiece, so that the long and thin workpiece is always processed in a supportive state.

Avoiding deformation: greatly reducing dimensional errors and surface defects caused by overhanging or jerky workpieces.

Enhance precision and surface quality: especially suitable for microfabrication of slender, soft or difficult materials.

Advantages of Swiss-type lathe in high-precision machining

1. Ultra-high dimensional stability

The guide sleeve structure makes the workpiece always be machined in stable support, and it can realize ±0.002mm or even higher precision, which is far more than that of traditional lathe.

2. One clamping, multi-process completion

can complete turning, milling, drilling, tapping and other processes in a single clamping, avoiding errors caused by multiple positioning, greatly improving the processing efficiency and yield rate.

3. Suitable for mass production

Its high automation, together with the feeder to realize unattended operation for a long time, is very suitable for small diameter, high precision, large quantities of parts of continuous machining.

4. High space utilization rate

The machine has a compact structure and a small footprint, which is suitable for the layout of automated production lines in precision manufacturing enterprises.
