Historical background

Swiss screw machining rises as an incredible solution to watch industries in the year 1870. Jakob Schweizer in creating fine parts for watches developed a lathe featuring moving headstock. His efforts clearley reflects that why the world renowned watch maker company Rolex has its foundations in Switzerland. After the development of lathe the Schweizer idea widespread around the globe just within a decade. In todays age the look and physical appearance of the swiss machine is far beyond than what they seem earlier one and a half century ago. Both in the efficiency and effectiveness Swiss machining surpasses the older machine although with same objective to develop thinner, and intricate components.

What is Swiss Machining?

Another name of the Swiss cnc Machining is Swiss screw machining or swiss turning. You can define it as a process which help you manufacture complex, smaller parts without compromising precision and accuracy. Using this process you can make parts with incredible tight tolerances. The Swiss type cnc machining is completely different from the standard lathes. In swiss machines the tool stay stationary while component moves and vice versa in lathes. With Swiss cnc machining you can create pins, screws, medical components, etc.

Main Components and Their Functions That Make Up CNC Swiss Machining

Sliding Headstock

The workpiece is clamped in the sliding headstock and is transported to and fro through the guide bushing. This motion allows the workpiece to machined closer to the cutting tools, which gives greater stability and accuracy.

Guide Bushing

The guide bushing holds the part secure as it passes through the machine, eliminating deflection and maintaining accuracy, particularly for longer, thinner parts.

Cutting Tools

Shapes the workpiece with various cutting tools like turning, milling and drilling tools. They can run concurrently improving efficiency.

Tooling Plates

Cutting tools are held in place by tooling plates. These plates are highly customizable in CNC Swiss machines for different tool setups.

CNC Controller

The brain of the machine is the CNC controller, which guides the entire single operation with extreme precision. It takes over the movements of the headstock, cutting tools, and guide bushing.

6. Collets

To clamp the work piece securely while it’s being machined, collets are employed. This tightens the grip and helps to maintain the part stable during the process.

Chip Conveyor

Metal shavings (called chips) produced during machining are removed by the chip conveyor. This allows you to keep the workspace clean and the workpiece from getting damaged.

Coolant System

The coolant system circulates liquid around the cutting tools and workpiece to keep them from overheating and producing a smooth finish.

Spindle

It spins the workpiece and drives the headstock. In Swiss machining it is often synchronized with the guide bushing for best control.

Sub-Spindle

Secondary operations, such as additional milling or drilling, are often performed on a sub-spindle that is mounted on the main spindle without removing the workpiece from the machine.

Bar Feeder

Raw material (in bar form) is given to the machine by the bar feeder, so the machine can run continuously without the need for manual intervention.

Tailstock (Optional)

The long parts are supported by the tailstock, which also helps reduce deflection while machining.

How Swiss Lathe Machining Works

Swiss lathe machining consists of a series of steps operated under careful control. Here’s a step-by-step explanation:

• Loading the Workpiece: The bar feeder passes a bar of raw material into the machine and stops the collets in the headstock.
• Guide Bushing Support: Guide bushing allows the workpiece to pass through, stability and deflection especially for long parts.

• Cutting Operations: Moving the workpiece, several different kinds of cutting tools varying from lathe (or turning), milling and drilling tools shape the part. These tools work at once and time is saved.
• Sub-Spindle Operations: The workpiece is then transferred to the sub spindle should the machining require additional cuts or drills but the part will not be removed from the machine.
• Chip Removal: The chip conveyor removes chips generated from cutting from the machine keeping it clean and accurate.
• Cooling: The coolant system throughout the process keeps the tools and the work piece at the best temperature to avoid distortion or damage.

Common Swiss Machining Operations

1. Turning

Turning cuts away the outer layer of the workpiece to reveal cylindrical forms. This operation plays a key role and falls into a fundamental category of Swiss turning machining.

2. Milling

Complex elements such as slots or grooves are created through the milling process. The workpiece can be turned while Swiss machines handle milling tasks simultaneously.

3. Drilling

Swiss machining drilling offers high accuracy and precision for making tiny and precise holes in the workpiece.

4. Threading

Creating internal or external thread shapes is part of the threading process. Swiss machines effectively perform both types of threading with superior accuracy.

5. Boring

Boring widens an existing hole to reach a specified diameter. This technique is utilized whenever there is a need for detailed precision on a specific hole size.

Common Tools Used in Swiss Machining

Several specialized tools make Swiss screw machining possible:

1. Guide Bushings

Guide bushings keep the workpiece in place while it traverses the machine to minimize deflection.

2. Cutting Inserts

These inserts are designed to conduct specific cutting tasks such as turning milling and boring which delivers a sharp and accurate cut.

3. Collets

The collets securely hold the workpiece so it remains stable and precise throughout machining operations.

4. End Mills

End mills complete milling tasks to customize the workpiece. They vary in size and form based on the challenge at hand.

5. Threading Tools

Tools that create threads are utilized to form threads on the workpiece being internally or externally threaded.

6. Reamers

Reamers ensure an immaculate appearance on the openings by providing them with the necessary dimensions and surface standards.
