Q1. We are using brushed stainless steel tubes, do you think the tube surface will be damaged, or holders of the tube should be protected with plastic holders or something similar?
A1：a. When the station hits towards the pipe, the clamp will not slide, so no strains. As long as the clamp groove is clean, no rubbish(like iron chippings, etc) in it, the surface of the pipe will not be damaged. Otherwise, the pipes might have pit after end forming.
b. In case the clamp groove got dirty, you can use a dishcloth to wipe the clamp groove( or a high-pressure air gun). Just pay more attention, no big problem.
c. We can’t use engineering plastic clamp here, that would be way too soft, can’t resist the impact force from the station. This is decided by the end forming technology.
Q2. Does this machine have a back stopper?
A2：Yes. All our tube end forming machine comes with a back stopper, it’s the standard configuration. But the position is adjustable. And it’s also optional, you can choose to remove it if you have very long pipes to process.
Q3. Is it any coolant liquid?
A3: (a) For end forming machine, we usually use drawing compounds lubricant, it mainly plays the role of lubrication and cooling during the processing process, which improves the workpiece finish, effectively extend the tooling life; and it’s easy to clean. (b)We usually manually brush it to the pipe surface. (c) The machine is equipped with a water cooling system, which can cool down the machine’s hydraulic oil temperature to make sure it works under long time.
Q4. I want the machine which works quickly. Servo the motor works quicker? In what he is better, than hydraulics?
A4:The main difference between servo motor control and hydraulic control is accuracy, not speed. If use servo motors, the mold shifting accuracy could reach ±0.015mm, hydraulic controlled mold shifting accuracy reaches ±0.1mm. Usually, for products that require multi-station(at least three stations), we would recommend using servo motors. The servo motor is more expensive.
Q5.What is the tube end forming machine vice clamp length?
A5:The standard vice clamp length is 165mm. If your pipe is shorter than this, we will customize the tools according to your product. Q6.I need air cooler on the machine, I don’t want water-cooled radiator, can you do that?
A6:Yes. Our standard machine is equipped with a water cooling system. If you want, we can make the air cooler for you.
Q7. For PLC, servo motor, servo drive you are using this of Mitsubishi so why don’t you use Panel view of Mitsubishi?
A7:There are two reasons for this. 1. Mitsubishi panel price is 3-5 times that of WeinView (we currently using from Taiwan), while displaying effect is same, so no manufacturers choose Mitsubishi here. 2. Mitsubishi Panel programming is very complicated, while WeinView is much easier. We have been adopting WeinView for many years, it’s mature and stable.
