LS 180/280 Gear Shaping Machines & LC280DC Gear Integrated hobbing and gear reversing machine

LS 180/280 Gear Shaping Machines

The machine design is characterized by a high degree of flexibility and can be tailored to the requirements of mass production.

The use of a mechanical gear shaping headstock increases the economical processing of workpieces.

LC280DC LC280DC Gear Integrated hobbing and gear reversing machine

Each design is just to bring you higher production quality and efficiency!!!!!!

Equipment features:

1. The integrated design of Gear hobbing and reverse gear greatly saves customers' investment in equipment and reduces the space occupied by equipment!!

Liebherr customers can equip independent chamfering cutting unit in the machine tool. The solution is two-in-one machine, which saves investment in special chamfering machine and necessary automation unit. It is not necessary to purchase a Gear hobbing machine and a reverse gear machine respectively for hobbing and reverse gear processing. Only one machine can meet the requirements. The initial investment can be reduced by about 10%, and the equipment space can be reduced by 30%!

2. The integrated design of Gear hobbing and chamfering does not increase the cycle time required for workpiece processing, but reduces the process length and makes the layout more reasonable!

The Gear hobbing and reverse gear processing is designed as a dual-station. The equipment duplex can be used for Gear hobbing and reverse gear processing at the same time. The processing does not interfere, and the reverse gear processing will not occupy the processing cycle time of gear hobbing!! Chamfering is carried out synchronously in the gear hobbing cycle, without additional beat; Even shorten the beat, because other suppliers need to do a roll-back roll (install a hob and chamfer cutter on a cutter bar, first rough roll, then chamfer, and then fine roll, which will cause the production beat of the whole workpiece to become longer because of the short length of the hob), or chamfer, which we do not need!!

The double-knife design used by the equipment is longer than the traditional round knife equipment. The service life of the chamfering tool is very long, which makes the customer's single cost extremely low. Each pair of tools can process about 130000 to 140000 pieces of new energy workpiece. On average, it can greatly save the total production cost of each product of the customer and improve the competitiveness!

4. The latest chamfering process, non-traditional chamfering process, avoids secondary burr, improves production quality and significantly reduces production waste!

Liebherr rolling-down machine adopts the latest double-tool cutting chamfering process, which is not used by other competitors, and has the following advantages:
I.  The burr can be avoided from being squeezed onto the production workpiece for the second time by the edge extrusion process, resulting in the generation of workpiece scrap!
II.  The chamfering process adopts the upper and lower blade cutting process, so the cutting surface is smooth and flat, and the workpiece surface produced by the chamfering process is rough and uneven!
III.  The chamfering process can perfectly avoid the problem of material processing stress, and the chamfering process will make the processing of the workpiece with material stress, and the chamfering angle of the workpiece will be deformed!
IV.  Mechanical interference has little impact on chamfering process, so the relative customers can achieve a wide range of angle process requirements when chamfering, and the chamfering process can achieve a relatively small range of angle due to interference.

5. The chamfer angle is adjustable, and the interference with the equipment is small, and the range of processes that customers can choose is wider!

Compared with the equipment of competitors, Liebherr selects the double blades for chamfering process cutting, which are relatively thin, but will not cause interference problems. They can cover the workpiece, especially the interference shaft parts, and for chamfering processing, the root of the tooth root can be perfectly processed. The range of customers can choose from 0.2-0.6 degrees is also large, and the tools used by competitors are relatively thick, Therefore, there will be interference problems, which will easily cause defects during tooth root processing. The angle range that can be selected is only 0.3-0.4 degrees, so many special workpieces cannot be produced.

6. High-precision processing quality to produce better products for customers!!

The angle and shape of the inverted teeth can be designed and adjusted on the operation interface, and the automatic program of the equipment will also automatically compensate and fine-tune to make the processed workpiece more high-quality and consistent in size and quality!
