LWN 120 Whirling Machine

In the traditional process of bit thread machining, the machining scheme adopted by most of the existing customers is

Turning + sandblasting

Weakness

Because the efficiency of lathe processing is very low, under the premise of increasing production capacity, resulting in the huge amount of lathe overall investment, and the increase of plant space will also be a challenge.
Due to the poor accuracy and consistency of the turning, the amount of sandblasting polishing will increase, the finished product precision will be difficult to control, and it will also bring some metal powder pollution.

 

 

LWN120 Whirling Machine

 

 

In the face of more equipment input and labor cost brought by traditional technology, Leistritz launched LWN120 whirling machine in the face of increasing requirements of the bit industry:
 

   

Advantages


1. The spiral lead Angle can be up to 45°, which is suitable for the helix Angle requirements of most bit threads;
2. Dry air cooling, more environmentally friendly;
3. Extremely high surface quality, subsequent processes may be omitted (depending on final surface requirements);
4. Diameter range of 9 mm to 48 mm, basically covering the mainstream bit diameter range;
5. Thread length from 200 to 1300 mm, automatic mode;
6. Under manual operation, ultra-long length processing can be achieved, and the maximum length can be produced to 3000mm;
7. According to the type of drill bit, the drill screw deburring, more flexible processing;
8. According to the type and geometry of the bit, the processing time can be reduced by at least 50% compared with the milling process.
