choice of tools for CNC turning small precision parts

The commonly used CNC turning tools are generally divided into three categories: forming tools, pointed tools, arc tools and three types. Forming turning tools are also called prototype turning tools. The contour shape of the processed parts is completely determined by the shape and size of the turning tool blade. In CNC turning processing, common forming turning tools include small radius arc turning tools, non-rectangular turning tools and thread tools.

CNC lathe parts processed by milling and cutting

Processing features: side milling, slotting on the shaft surface. For the two parts, four cylinders protruding longitudinally on the shaft surface are milled on the side, and curved grooves on the shaft surface are milled on the side. CNC lathe processing with power tool head, the tiny milling blade mills out flats or grooves of various sizes.
The two products on the left are made of brass. Nickel-plated connector parts are the connectors of data network cables, and the connection plugs of computers or video equipment are common. The outer diameter is 16mm and the length is 25mm. The other copper part is the copper valve core of the flow control valve, with a maximum diameter of 11mm and a total length of 30mm.

CNC Lathe Turning Complex Shape Parts Groove

An example of a larger CNC lathe turned part.
The left part of the picture is a larger stainless steel turning part. Material SUS304, hexagonal opposite side H (height) 45mm, turning thread, turning inner wall, two-level through hole. Although the shape and installation are simple, the machining volume of turning is large. The big picture is attached.

cnc turning of industrial connectors

Machining method of CNC slitting automatic lathe:
It is suitable for processing complex geometric shapes and high-precision connector parts. The equipment is easy to adjust and replace parts. But the cost of the machine is high
Applicable batch parts: small batch manufacturing

CNC Turning Precision Parts Service

CNC lathe processing is a high-tech processing method of precision hardware parts. Various types of materials can be processed: 316, 304 stainless steel, carbon steel, alloy steel, alloy aluminum, zinc alloy, titanium alloy, copper, iron, plastic, acrylic, POM, UHWM and other raw materials. It can be processed into a complex structure of square and round parts.

Custom Copper Precision Turning Parts

Our company is good at turning all kinds of copper parts, all kinds of valve parts, electrical bronze parts, brass nuts, mobile phone antennas, external knurling (straight grain / twill / net grain) and so on. The picture on the left shows a turned copper core. Used in valves, the material is C3604 fast-cutting steel brass, and the copper turning parts customized according to customer requirements are used as the valve stem and valve core. Used in valves of internationally renowned brands. Automatic turning and forming, after the head milling edge and the rod milling edge, the angle is 60 degrees. Slotted head. The outer diameter is 12.7mm, and the total length is 70mm. The forming turning tool has been used many times in the processing of this copper precision part. In order to solve the accuracy of the R angle and chamfering of the inner groove, CNC machining was initially adopted. Later, in order to save costs, automatic lathe processing was used.

Fixture and tool setting of lathe turning parts

Clamping of turning tools
1) The shank of the turning tool should not extend too long from the tool holder, and the general length should not exceed 1.5 times the height of the tool shank (except for turning holes, grooves, etc.)
2) The center line of the tool bar of the turning tool should be perpendicular or parallel to the cutting direction.
3) Adjustment of the height of the tool tip:

Lathe turning precision copper electrical parts

The picture on the left shows a copper turning part with internal and external threads. Wait, something seems wrong. . . . . . Is this copper?
That’s right, this is a copper turned part, made of C3604 fast-cutting brass, the surface is electroplated, and the plating is nickel-plated, so it looks like stainless steel.
This product has both internal thread and external thread, internal thread is M4, external thread is M6. While the outer threaded upper flat sided milling, and thread to ensure 100% compliance.
How do we lathe such internal and external threaded products? You can refer to this address, the first product on this page is the semi-finished product of the product on the left (unmilled, unplated, copper color):

Precision turning of earphone metal fittings

Machining of copper and aluminum parts of earphones
1. The processing route of earphone metal fittings has great uncertainty. A component or product can have multiple processes, and the production process requires a wide variety of machinery and equipment and fixtures.

Precision turning process of large threaded shaft

Ordinary lathes sometimes experience bed saddle vibration when turning large-pitch threads forcefully. Lighter ones will cause ripples on the machined surface, and severer ones will break the knife. When cutting off, there are often knife sticking or broken tools. There are many reasons for the above problems. This phenomenon and its solution are mainly discussed through the analysis of the force of the turning tool.

Turning is a process by which material is cut to create round shapes, typically using a CNC Lathe. The workpiece is placed inside the lathe and rotates while a cutter removes material until only the desired shape remains.

Turning is ideal for cylindrical parts and is primarily done using round rod material, but square and hexagonal bar stock can also be used.

The primary objective of CNC turning is to machine parts having shapes that can be formed by feeding a cutter into a rotating bar of raw material. Turning can also be used to reduce the diameter of a workpiece to a desired dimension. Lathe turning is mainly used for shaping metal or wood.
