Is it possible to use milling angel head on any kind of machine tool?
Heads are designed for boring and milling machines with taper shanks SK40 and SK50. If spindle is tipped up in other angel than 0° or 90° than adjustable heads PVI or PVM need NC, CNC machine with continuous control.
What are conditions for putting the milling angle head on machine tools?
Necessary is to choose suitable machine and beside spindle install retaining block which holds case of head. Block is a part of head accessories. Distance from machine spindle centerline is given by modification of arresting arm. (spot height A)
What is necessary to consider before purchase of milling angel head?
Usage measure of head, its necessity (head is for filigree not for stocking). Real possibility of head setting on the machine.
Is it possible to use inner coolant by these heads?
No it is impossible. Heads are not designed for this type of coolant. If you would need it, firm NAREX MTE is able to offer you special solution which will make inner coolant possible.
What to avoid during using this head?
First of all you must avoid its overloading what has main influence over shortening bearings and bevel gears durability. We recommend the cooling fluid (especially by adjustable heads) not to spray in bigger size on head case. The fluid can get inside the case and destroy bearings.
What are the most frequent failures of milling angel heads?
Worn bearings on the spindle what will be manifested by marked higher run-out and higher vibration.
Usability and possibility of function test by form of loan.
Usability and possibility of function test by form of loan.
What are demands on machine tool?
A - clamping spindle cavity must be in such condition that the clamping is accurate and rigid. B - spindle and machine table seating must has necessary rigidity to prevention undesirable vibration during machining
With what accuracy is possible to clamp tools to the spindlespeeder?
Measured untrue running clamped in diameter "d" in distance 2,5 d from the collet edge: In diameters range d 1,0 - 10,0 mm is maximum 0,02 mm In diameters range d 10,0 - 20,0 mm is maximum 0,025 mm.
How is service life limited?
Machine has lasting grease packing with service life 2.500 running hours. During run in groove should not be the temperature higher than 60°C and noisiness 80 dBA/1m. Spindle run-out should not be higher than 0,025 mm for collet on the cavity edge and axial clearance must be zero everytime.
