FF-series --- Friction Welding Machine

| Friction Welding Machine FF-series (Standard Model)

Since its foundation in 1966, NITTO SEIKI has been manufacturing and selling FF-series to a large number of customers all around the world. As a result of repeated improvement, research and development, FF-series has become an icon of friction welding machines.

FF-series has many features such as 1) high performance and great structure which enable high-quality welding, 2) easy operation, and 3) powerful new functions. All such accumulated experiences and newest technologies grow into one and brings users an innovative welding experience that has never been experienced before. Because of its high standard performance, this is the machine recommendable for those users who could not satisfy with up-to-now welding.

Structure
 
Machine base

Spindle

Sliding table

Machine base To resist high forge force and to have higher welding precision, it has tough welded steel plate construction. It supports high-quality friction welding process with high endurance. Spindle The original design of bearing which resists high-speed rotation and high forge force achieves outstanding endurance. The endurance of a spindle cabinet made of cast iron is secured by fixing it to the main body base. (Except for special models such as movable head models) Sliding table By installing a horizontal vise clamp which is lighter than the spindle cabinet on the table, it reduces sliding resistance and achieves a long lifetime. The rail has linear guides and keeps the sliding resistance as low as possible. 
Disc brake
Spindle drive system

Sliding table positioning detection

Disc brake To secure stable dimension accuracy, it is equipped with hydraulic disc brake that has high reliability in controlling accuracy. It has an easy structure in changing break pad and makes the maintenance easy. Spindle drive system The drive of the spindle transmits directly to the material through power belt by the variable motor. The spindle rotation speed can be set at any speed by inverter control. Sliding table positioning detection Installed with high precision magnetic scale, positioning can be detected precisely and also can easily be set by inputting numerically. Neither complicated adjusting nor maintenance is needed with the non-contact high precision magnetic scale.
Chuck unit

Clamp unit

Hydraulic control

Chuck unit The chuck unit on the rotating side can be selected either from 3-jaw power chuck or collet chuck, depending on the shape of the work. The jaw can be designed specially to fit to the workpiece. Clamp unit The material on the fixed side is clamped by a hydraulic horizontal vise clamp of both sides open-close wick adjustment. 
The original structure made high precision and stable grip possible.
Hydraulic control In friction welding, control of forge force has a great influence on weld quality. Controlled by originally programmed electromagnetic proportional valve, high-precision welding can be achieved.
Good legibility from central arrangement of pressure gauges

Front Sliding Door

Good legibility from central arrangement of pressure gauges By arranging each pressure gauge centrally, high legibility is secured. Front Sliding Door It prevents scattering of swarf and secures the safety of the operator. 


Operatability

Operational panel

Touch panel

Revolving operational panel

Color LCD touch panel is a standard feature and is excellent in legibility. It also responds instantly to the changes in setting.

Equipped with 10.4inch large color display, a great deal of information can be displayed.
Data can be operated directly with the touch panel.
Entry of the setting can be done with interactive screen menu.
Instant change of setting is possible by calling for a conditional data.
In case of trouble, error can be detected by alarm display.
Revolving operational panel It can revolve to easily operational angle.


Data input support
 
Data input and call function of welding condition --------------- Up to 100 data can be stored.
Numerical setting of the sliding table position  --------------- High-precision non-contact magnetic scale is installed for accurate detection of the position and easy maintenance is achieved.
Automatic forge-force calculation function --------------- Forge force is calculated and set automatically by inputting the value of the welded major diameter, minor diameter and pressure.
Automatic spindle-circumferential speed calculation function --------------- Circumferential speed is calculated and set automatically by entering the value of the welded major diameter, minor diameter and the spindle rotation speed.


Quality confirmation
This is the function to monitor the parameters which affect the welding quality by detecting actual values after each welding cycle and by comparing with maximum and minimum monitored values. Historical results from detection can be recorded in external USB memory.
 
Friction time Spindle rotation speed
Friction pressure (P1) Brake time
Upset pressure (P2) Material length
Total loss Complete length


Convenient fuctions
 
Forge force high-low changeover switch  ------------------- Low forge- force controlling area expands approximately 5% more compared to the past.
Automatic warm-up operation ------------------- Warm up of a spindle and a sliding table is done by an automatic program.
Energy-saving pump operation ------------------- Not operated for a certain period of time, pump stops and saves energy.


Maintenance
Automatic refueling
to the sliding surface


Replace of brake pads

Central arrangement of devices

Automatic refueling to the sliding surface Each sliding surface is greased automatically and protected by an intermittent refueling of lubricant.
For easy maintenance, filler is placed left front of the machine.
Replace of brake pads Brake pads are consumable goods. For easy maintenance, it has a structure that enables the user to replace pads easily through caliper attachment bracket hole. Central arrangement of devices1 Central arrangement of devices2
Hydraulic devices and air devices are arranged centrally for easy maintenance.
Power belt

Pressure monitoring
for spindle lubricant


Oil cooler

Power belt Tension of the power belt which transmits the drive of the motor to the spindle can be checked through maintenance window on the front of the machine base.
Pressure monitoring for spindle lubricant Supply of lubricant to the spindle has two important roles; keeping the lubrication and also cooling down.
The pressure switch monitors the fall in supplying pressure and secures the endurance of the spindle.

Oil cooler

For a stable operation, temperature management of active oil and spindle lubricant is an important factor.
Energy-saving inverter controlled oil cooler has less change in temperature and controls oil temperature.

Alarm display

Immersion heater


Standard tools

Alarm display Immersion heater To prevent excess decline in oil temperature in cold area, an immersion heater is installed and reduces start -up time greatly.
Standard tools Tools necessary for set-up changes and daily maintenance are attached standardly.
Any trouble on the machine will be shown as an alarm display on a touch panel screen. Such history will be displayed as an error log.
