TOOLHOLDERS INSTRUCTIONS

Thank you for choosing our products.

For best results, please follow below instructions.

GENERALITIES

Each toolholder has passed a QC test and has a documented specification, attesting his geometric precision.

Our toolholders are equipped with high-quality sealed bearings that ensure a long service life. The grease that is used is Kluber or Isoflex.

Each toolholder is checked for temperature and vibration parameters on the test bench. This means that the toolholder is ready to start working in the production process!

PLEASE NOTE

Keep these instructions, with care, to have them whenever needed for consultation.

Be aware of any state law to avoid accidents for yourself and others by using live toolholders. Be careful when handling the toolholders to prevent it from falling, which could cause injury to yourself and others. Until the toolholder is attached to the turret, use rubber or plastic tool sleeves to avoid injuries caused by the tool cutting sharp edges.

If the toolholders are overloaded, there may be major damage in the operation of the product. In this brochure it is using symbolic representations. Some accessories shown are not included, as standard, with delivered toolholders.

1. INSTALLATION AND FUNCTIONING

1.1 Cleaning and care

For cleaning, use a soft cloth. Do not use compressed air to clean the toolholders.

To achieve a long life of toolholders, please do not use strong chemical cleaners. Protect the surfaces of the toolholders with oil or other anti-corrosion products during storage.

1.2. Transmission, bearings and lubrication

Bearings and gears are lubricated with high quality lubricants for the lifetime of toolholder. Any additional lubrication is not required under normal operating conditions.

Additional data such as torque, maximum speed, etc. can be taken from the product datasheet.

1.3. Fixing on the turret

In principle, in order to guarantee an optimal function of the toolholder, a clean surface of the turret interface and the couplings is required. Only this ensures the highest possible accuracy in the cutting process.

1.3.1. Mounting the toolholders on the turret

Please inspect the contact surface of the turret (7). It must be clean and without chips.

Please check that the ring O-ring (8) is not damaged.

Insert the cylindrical part of the toolholder into the turret. Please ensure that the drive shaft (9) engages with the turret drive.

Enter the toolholder inside turret until the interface contact is well done. Ensure the toolholder is firmly tightened.

BMT turret: Mount the holder on turret and firmly tighten the bolts (4).

In order to remove the toolholder from the turret, just rotate the two set screws (5) clockwise. After the toolholder is released, you must rotate back the set screws until they are positioned below the mating surface of the toolholder with the turret, see picture above.

Okuma BMT turret: Mount the toolholder on turret and slightly tighten the bolts (4). The toolholder will be centered by tighten the screw (6). Tighten firmly the screws (4).

VDI turret: mount the holder on turret and tighten the rack screw with the hexagon key (10) firmly.

NOTE: The coupling of toolholder must be aligned with similar coupling from inside turret interface. If the toolholder cannot easily be inserted into the turret, then remove the toolholder from the turret surface. In this case, please use the machine's operating instructions.

Particular case: for Live Toolholders with coupling type DIN 5480, for making coupling, toolholder’s shaft need to be in locked position, so no rotation. This position is realized when ring beak (33) is in position from this picture.

1.3.2. Aligning the VDI angular toolholder

The angular toolholders can be equipped for alignment with one of the following systems:

The toolholder will be set as follows: gently squeeze the toolholder on the turret through toothed rack in the recess by tightening a hex key (10) to allow the alignment. Align the toolholder with a dial comparator clock (14), by displacing it along the whole length of aligning area (surface), using for adjusting threaded pins (12). Once you have aligned the toolholder, you must tighten the threaded pins (12) and secure them with nuts (13), then firmly tighten the rack screw with the hexagon key (10).

At the end of alignment operation check again position set-up.

1.3.3. Aligning the Okuma BMT toolholder

The toolholders do not need any setup, but if from some reasons you need to fine tune the position of the toolholder then you have 2 screws (13), to do this job. You must do this setup before the final tightening of the screws (4).

1.4. Variable Angle Toolholder - Angle setting

The screws (15) will be loosen. Set the desired angle and firmly tighten the screws (15). Check the set angle, with a Digital Angle Finder or a Protractor, measuring by comparison the angle between the cutting tool and axle of the spindle (chuck).

1.5. Clamping the tool

1.5.1. Fixing the cutting tool in collet

Insert the collet (16) into the ER clamping nut (17) until it enters inside locking way.

Firmly tighten the ER clamping nut using 2 (two) keys, as in bellow picture.

1.5.2. Fixing the cutting tool in Weldon output

Insert the cutting tool (18) (with the milled surface against the retaining pin) into the shaft hole and lock with the threaded pin using the hexagon key (19).
