Process automation is crucial to increase productivity. Using bars as stock material is very common in turning world and although the use of barfeeders is extended, the automation gets more complicated...

All CMZ lathe models are equipped with a standard chip breaking function. Using a different feed rate during the same pass the chip is broken. As federate is changed the surface quality is affected and...

Chip accumulation is a common problem with external and internal thread turning. The fact that the chips do not break can create long tangled chips that can damage the surface of the part or stay inside...

Thread milling with helical interpolation is a process that allows the ability to machine threads as an alternative to rigid tapping. Sometimes, rigid tapping is not feasible due to the power requirements...

Machining stainless steel, duplex or super duplex requires that the machine tool used is robust, stable and with an adequate power due to the mechanical characteristics of these materials. The lathe TD...

Measurements during the manufacturing process are required for long machining runs where tool wear must be corrected and compensated during the machining operations. It is also required in order to remove...

Every machining process can be a challenge in itself. With CMZ's recently expanded automation solutions for loading and unloading components, you will find the answer to improve the productivity of your...

With this configuration, customers can machine parts in the main-spindle with the tailstock engaged using the upper turret, while simultaneously machining parts in the sub-spindle with the lower turret....

The latest Fanuc Plus control allows to import DXF geometries directly into the CNC lathe. Just import the file into the machine, select the origin of the part, working plane and contour and define the...

Machining gears has always been a challenge. For years it has required a dedicated machine and an additional operation to machine the teeth in the part. However, in recent years different options for machining...

One of the most critical aspects in many machining processes is chip formation. Long and entangled chips are formed mainly in turning operations due to constant cutting conditions. This issue requires changes...

The TTS and TTL Series make up the multi-turret family of machines for bar work. This is the smallest lathe in the whole product range. Its precision and reliability guarantee the quality of this machine,...

Normally several clampings would be needed to finish the parts, or in some cases very specific transfer machines could also be used, but the investment would be much higher. To allow this indexation and...

WHAT IS MILLING? Milling is a chip removal manufacturing method that mainly consists of cutting material using a multi-edge rotary tool. Performing milling operations on a CNC lathe allows the spindle's...

This video shows two internal broaching processes with static and live toolholders. Making the keyways with broaching toolholders on a CNC lathe reduces time since the part is made in a single operation,...

We would like to welcome helical gear hobbing in a CNC lathe and say goodbye to the dead time that occurs when you have to turn and hob on two different machines. The range of possibilities is very broad...

The geometry of the gear in the gear hobbing process is obtained by the synchronised movement between the spindle and the live tool. The limit to manufacture gears in a CMZ CNC lathe is around the hob...

Usually in components where lubrication or coolant is necessary deep holes can be found in the workpiece to access required positions. The question is often if it is feasible to do it in a CNC lathe....

Manufacturing processes usually require different type of machines to finish a component. In order to ease the movement between machines and ensure precision, clamping fixtures can be used. CMZ has developed...

It is quite usual that we find features like internal and external keyways, hexagons or torx in our drawings. Sometimes these are done in a separate operation in a standalone broaching machine or they...

This powerful 66mm bar capacity twin turret twin spindle CNC lathe can cut with 3 or even 4 tools simultaneously making the TTL a great machine for producing higher volumes of complex parts. Superimposed...

Chatter must be avoided at all costs. Chatter not only produces a poor surface finish on diameters but also seriously limits tool life. Long slender shafts, extended boring bars, thin walls and so on,...

This system is not limited to billets, CMZ manufacture gripper heads and workstockers both for billets and shafts. The combination of a barfeeder and Gantry Loader can be a very effective way to manage...

Machining processes sometimes require different machines to produce a part. Although CMZ offers automation solutions with the gantry series which are valid for many components not always they adapt to the...

Material is a considerable percentage in component cost. In order to avoid large material waste on the cut off, the blades are usually very thin and long, which often lead to vibrations and bad surface...

Our TD series of lathes are ideal to machine this type of component. When equipped with a travelling steady accuracy and surface finish can be maintained along the entire length of long and slender diameters, supporting...

Thread rolling may be your solution. This process forms the thread by shaping the metal, without removing chips. This is done using rollers that are the "negative" of the thread being produced. The machining...

This system gives a pressure up to 70bar, being able to select different pressures by M codes. It uses so called elementless filters that are a hybrid between centrifugal separators and liquid cyclones....

Integrated motors on both turrets offer a combination of two 12-station turrets (24 live positions) and 14kW/42Nm driven tool power with spindle speeds of up to 12,000 rpm, a massive advantage for achieving quicker...

When the geometry of the part allows it, it is even possible to cut with four tools at the same time performing a double balance cutting process.  One of the turrets and the subspindle (TOOL 1+TOOL 2)...

CMZ presents their new CNC lathe series TTL.  This a new generation of lathe that can be included in the multiturret range together with the TX series. Its rapid speed of 30m/min, milling capacity up...

We can often find features in our drawings where an angular machining operation is required. With standard toolholders these features are not achievable because only operations in X and Z directions are...

In the current industrial scenario Industry 4. 0 is a trend that many companies are adopting. In CMZ we are working to help our customers achieve their goals into this matter. All CMZ CNC lathes equipped...

Does your application require in-process measurement? CMZ offers an accessory that can help you with this challenge. This application is usually used in long series runs where the tool wear has to be adjusted...

Do you need to automate your production process to reduce idle time and improve yield? CMZ offers various possibilities for automation. The GL 20II Gantry Loader has been designed by CMZ to automate short...

A solution to automate the process of machining shafts in your CNC lathe.  Our GL20II gantry loader system combined with the WS700 workstocker for shafts allows you to leave you machines running unmanned....
