What is Screw Machine Automatic Turning?

Screw Machine Automatic Turning, also known as Swiss Turning, is an efficient process for creating small components with an extremely high level of precision. It uses a lathe where the material is turned and rotated around its axis while exposed to a cutting tool. This cutting tool removes unwanted material from the spinning workpiece, while at the same time forming the desired shape.

The process begins by placing the bar stock into the chuck of the lathe. The bar stock is then held in place by clamps and cut offs are completed by a pre-set automatic tool that is fixed to the lathe. The automatic tool then works to shape the bar stock into the desired product.

Benefits and Advantages of Screw Machine Automatic Turning

Quality Swiss Type CNC Machining Services

Ming Xiao Manufacturing is an experienced supplier of customized precision turned parts and offering quality swiss type CNC machining services with the capability to satisfy your accuracy, complexity and quantity requirements worldwide.

What is Swiss type CNC lathe?

Swiss type CNC lathe – the full name of the center walking CNC lathe, also known as the spindle box mobile CNC automatic lathe, economical turning and milling compound machine tool or slitting lathe. It belongs to precision machining equipment, which can complete compound processing such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch processing of precision hardware and special-shaped shafts.

Features and advantages of Swiss type CNC lathe:

(1) Shorten the product manufacturing process chain and improve production efficiency. Swiss type CNC machining can realize all or most of the machining processes in one loading, thus greatly shortening the product manufacturing process chain.

In this way, on the one hand, the production auxiliary time caused by the change of the loading card is reduced, and at the same time, the manufacturing cycle and waiting time of the tooling and fixture are also reduced, which can significantly improve the production efficiency.

(2) Reduce the number of clamping and improve the machining accuracy. The reduction in the number of card loadings avoids the accumulation of errors due to positioning fiducial conversions. At the same time, most of the turning-milling composite processing equipment has the function of online detection, which can realize the in-situ detection and precision control of key data in the manufacturing process, thereby improving the processing precision of products.

(3) Reduce the floor space and reduce the production cost. Although the price of a single turn-milling compound processing equipment is relatively high, due to the shortening of the manufacturing process chain and the reduction of equipment required for the product, as well as the reduction of the number of fixtures, workshop area and equipment maintenance costs, it can effectively reduce the overall fixed assets. The cost of investment, production operation and management.

Design Features Of Swiss CNC Lathe:

Since the structure of the Swiss type CNC lathe is different from that of the traditional CNC lathe, the processing efficiency and machining accuracy of the Swiss type CNC lathe are higher than those of the CNC lathe.

The machine adopts two-axis arrangement of tools. This design greatly saves the processing cycle time. By shortening the tool exchange time between the arrangement of tools and the opposite tool table, the overlapping functions of multiple tool tables and effective axis movement of thread chips are realized. , The direct spindle indexing function during the secondary processing shortens the actual and empty travel time.

Cold Forging Services Make Steel Parts More Cheaper.

Ming Xiao as a metal parts manufacturer custom cold forging parts many years,we produce standard welding nuts,locking nuts with metric threads, and use cold forging process to produce rough parts for our turning parts and machining parts to save the material cost.

The cold forging process also known as cold heading, it’s one of the new processes for processing metal cutting without cutting.

It is a method of processing the required parts or blanks by utilizing the plastic deformation of the metal under external force and by means of the mold to redistribute and transfer the metal volume. The cold heading process is best suited for the production of standard fasteners such as bolts, screws, nuts, rivets, pins.

The equipment commonly used in the cold heading process is a dedicated cold heading machine. If the production volume is not too large, it can also be replaced by a crank press or a friction press.

Accuracy of cold forging

The most difficult thing to control in cold heading machining is the length tolerance, and the current market precision is about ±0.1mm.

Other inner or outer diameter tolerances are easily controlled within ±0.05mm. With the advancement of technology, the current continuous die precision forging process can control the length tolerance of cold heading machined parts to about ±0.02mm, but it depends on the size of the product.

We can provide punch press deep drawing & hydraulic press deep drawing services,can satisfied different deep drawn parts processing requirements.

What is the difference between hydraulic press and punch processing?

We have to understand the difference between the punch and the hydraulic press: the punch is rigid and cannot be adjusted in speed. In the case of a large amount of extension, the punch may crack.

Therefore, in terms of product processing difficulty, hydraulic presses are usually used to process workpieces with large dimensions, more deeper drawing, complex shapes, and high precision requirements. Punch presses are generally used for smaller, round,less deep drawing and less precise workpieces.

There are different uses, power and principles. Most of the punches are used to punch thin plates. The finished products are also hydraulically used to punch plates with better plasticity in one plane, while the three-dimensional finished power punches are usually electric. The big one is also the hydraulic hydraulic system principle, the punch shearing principle, the hydraulic plastic deformation.

What Is Stamping?

Stamping is the forming process of the workpiece (stamping part) by applying external force to the plate, strip, pipe and profile by press and die to produce plastic deformation or separation. Stamping and forging belong to forming processing (or pressure machining). The stamping materials are mainly hot rolled and cold-rolled steel plates and steel strips.

Stamping is the production technology of product parts with a certain shape, size and performance by using the power of conventional or special stamping equipment to make the sheet metal directly deformed and deformed in the mold. Sheet metal, mold and equipment are the three elements of stamping process.

Hot Stamping And Cold Stamping

According to the stamping temperature, it can be divided into hot stamping and cold stamping. The former is suitable for sheet metal processing with high deformation resistance and poor plasticity, while the latter is carried out at room temperature, which is a common stamping method for thin plates. It is one of the main methods of metal plastic processing (or pressure machining), and also belongs to material forming engineering technology.

The Stamping Die For Sheet Metal Forming

The die used for stamping is called stamping die, or die. Punching die is a special tool for batch processing material (metal or non-metal) into the required stamping parts. Punching die is very important in stamping. Without the punching die that meets the requirements, mass stamping is difficult to carry out. Without advanced die, the advanced stamping process can not be realized. Stamping process and die, stamping equipment and stamping materials constitute the three elements of stamping process, only if they combine each other to get stamping parts.

The Steps Of Stamping Process

Stamping is mainly classified according to technology, which can be divided into two categories: separation process and forming process.

The separation process, also known as blanking, aims at separating the stamping parts along the contour line and ensuring the quality requirements of the separation section.

The purpose of forming process is to make the sheet metal plastic deformation without breaking the blank, and make the workpiece with the required shape and size. In actual production, many kinds of processes are usually applied to a workpiece. Blanking, bending, shearing, stretching, bulging, spinning and straightening are the main stamping processes.

Separation process

(blanking)

It is a basic stamping process using die separation material. It can be directly made into flat parts or for other stamping processes such as bending, drawing, forming and so on. It can also be cut and trimming on the formed stamping parts. Blanking is widely used in automotive, household electrical appliances, electronics, instrumentation, machinery, railway, communications, chemical industry, light industry, textile and aerospace and other industrial sectors. Punching process accounts for about 50% to 60% of the whole stamping process.

Forming process

Bending: plastic forming method for bending metal plates, fittings and profiles into a certain angle, curvature and shape. Bending is one of the main processes widely used in stamping parts production. The bending of metal material is essentially an elastic-plastic deformation process. After unloading, the workpiece will produce elastic recovery and deformation, which is called springback. Springback affects the accuracy of workpiece, which is the key technology that must be considered in the bending process.

Deep drawing Of Stamping Process

Deep drawing also known as drawing or calendering, is a stamping process using moulds to make flat billets into blanks after punching. The deep drawing process can be used to make cylindrical, stepped, tapered, spherical, box shaped and other irregular shaped thin-walled parts. If combined with other stamping processes, parts with extremely complex shapes can also be manufactured.

In the stamping production, there are many kinds of drawing parts. Because of its different geometric features, the position of the deformation zone, the nature of the deformation, the distribution of the deformation, and the stress state and distribution of each part of the blank are quite, even the essential difference.

Therefore, the determination of process parameters, procedure number and sequence, and the design principles and methods of mold design are different. According to the characteristics of deformation mechanics, all kinds of deep drawing parts can be divided into four types: straight wall rotary body (cylindrical part), straight wall non revolving body (box body), surface slewing body (surface shape part) and surface non revolving body.

The tensile force is applied to the sheet material by the drawing die to produce uneven tensile stress and tensile strain, and the bonding surface of the plate and the drawing die gradually expands until it is completely fitted to the drawing model. The main object of the drawing is the hyperbolic skin with a certain plastic, large surface area, smooth and smooth curvature, and high quality (accurate shape, smooth streamline and stable quality). Because the process equipment and equipment are relatively simple, the drawing cost is low and flexible, but the material utilization and productivity are low.

Process Used For Deep Drwaing

Spinning is a metal rotary processing technology. In the process of processing, the billets are actively rotated with the spinning die or spinning head around the billet and the spinning die actively, and the spinning head is fed by the core die and the blank. The blank revolving parts are obtained by the continuous partial deformation of the blank.

Shaping is the two trimming of the shape of the product using the shape of the tool. It is mainly reflected in the pressure plane, the bullet and so on. In view of the elasticity of some materials, it is impossible to guarantee the quality of the forming.

Bulging is the processing method of obtaining parts by using die to make sheet metal thinning and increasing surface area. It is commonly used in the form of undulation, bulging of cylindrical (or tubular) blanks and stretching of flat blanks. Bulging can be realized by different methods, such as bulging, rigid bulging and hydraulic bulging.

Flanging is a plastic processing method to bend the material in the narrow strip area of the edge of the blank or the edge of the blank on the curve or straight line. The flanging is mainly used to strengthen the edge of the parts, remove the cutting edges and make the parts assembled and connected with other parts on the parts or the three-dimensional parts with complex specific shape and reasonable space, and improve the stiffness of the parts. In large sheet metal forming, it can also be used as a means to control breakage or crease. So it is widely used in automobile, aviation, aerospace, electronics and household appliances.

Necking is a stamping method that reduces the diameter of the flanged hollow part or the open end diameter of the tube blank. The change of the end diameter of the workpiece before and after the necking should not be too large, otherwise the end material will wrinkle because of the severe compression deformation. Therefore, it is often necessary to shrink the necks from smaller diameters with larger diameters.

China CNC Turning Services Custom Turned Parts

CNC Turning is a machining technics that widely use in machine parts production, it’s on a lathe and using the rotation of the workpiece and tool motion in a straight line or curve motion to change the blank shape and size, it processed into conform to the drawing requirements.

And the lathe machines are different for different workpieces, low precision & normal quantity turned parts should be made by manual lathe, some small turned parts & with high volumes should work on automatic turning lathe, and some parts with very high precision request(such as in 0.05mm),that we shall consider use CNC lathe to work.

CNC Precision Turning

CNC lathe machining is a high-precision, high-efficiency machining method for controlling the displacement of parts and tooling with digital information for automated machine tools. It is an effective way to solve the problems of variety, small batch size, complex shape and high precision of aerospace product parts and realize high efficiency and automatic processing.

CNC lathes are one of the most widely used CNC machines. CNC lathes are mainly used for machining rotary parts such as shafts and discs. Through the operation of the NC machining program, the cutting process of the inner and outer cylindrical surface, the conical surface, the forming surface, the thread and the end surface can be automatically completed, and the work of the groove, the drilling, the reaming, the reaming, and the like can be performed. The turning center can complete more machining operations in one setup, improve machining accuracy and production efficiency, and is especially suitable for machining complex-shaped rotary parts.

Some ordinary machine tools can not or inconveniently process parts, the processing quality is stable, and the labor intensity of workers is reduced.
