Tool Life x 3 Times in SUS SIM Card Holder Machining with Ultrasonic

At present, there is an rat race in the consumer electronics industry, leading to the further demand upgrade of terminal market, high-end development of electronic products, as well as higher quality, higher efficiency and lower cost machining.

SIM card holder is one of the indispensable precision components in mobile phones. Although its machining technology has been relatively mature, it is still a big challenge to realize high-efficiency and high-precision machining. In this issue, we will share a successful case of machining stainless steel SIM card holder with Conprofe Ultrasonic-Green Machine Tool, which improves tool life nearly 3 times.

Customer’s Challenge

1、Workpiece: Mobile Phone SIM Card Holder

2、Material: SUS 316

3、Machining feature: Grooving and Drilling

This time we need to machine SUS 316 mobile phone SIM card holder, and its machining requirement is to groove and drill on the stainless steel sheet. Under the traditional scheme, customer suffered poor tool life.To solve the problem, Conprofe machines it by using Ultrasonic-Green Drilling and Tapping Center AMT-500 with ultrasonic machining system and SmartGuy 4th axis rotary table.

Ultrasonic-Green Drilling and Tapping Center AMT-500

Main Features:

1、Equipped with ultrasonic machining system and Minimum Quality Lubrication (MQL) system, which is environmental friendly without coolants

2、Optional BBT-30 ultrasonic through-spindle cooling, with maximum speed up to 24,000rpm

3、Multiple tool magazine options (21T/26T/30T/36T/30T+14T)

4、Distance from the spindle nose to worktable is 150-500mm

5、Optional 5th axis rotary table

Machining Advantages:

1、Effectively reduce the main cutting force and temperature

2、Reduce the subsurface damage (SSD) and machining stress of hard-brittle materials

3、Reduce roughness

4、Extend tool life

5、Improve surface integrity of the workpiece

Main Features:

1、High precision, heavy load, large torque, high rigidity, no backlash, safe and reliable

2、Conprofe Machining Solution’s Advantage

3、Compared with the original scheme, the Conprofe machining advantage is more outstanding. Ultrasonic machining increases the average tool life by 286%, effectively reduces tool change times and cost, improves machining efficiency, and also optimizes surface quality. Eventually the customer satisfies with Conprofe solution and positive effect.
