Proxxon MICRO miller MF 70

NO 27 110

1. Handwheels with zero adjustable scales, 1 revolution = 1mm, 1 division = 0.05mm.
2. Continuously variable speed from 5,000 – 20,000rpm, perfect for even the smallest milling cutter.
3. Cutter clamping in MICROMOT system collets.
4. Table of stable aluminium. Both axes are fitted with adjustable dovetail slides.
5. MICROMOT steel collets, triple slit and hardened, from 1 to 3.2mm.
6. Stable cast iron base.
7. Supplied complete with stepped clamp blocks of steel.

 

The accurate miller for delicate projects. Spindle speeds 5,000 – 20,000rpm. For work with extremely small cutters.

Stable grey-cast iron machine base, vertical guide and compound table. Free from play, readjustable dovetail gib in all axes. Die-cast aluminium arm housing, with 24-pin special motor (balanced). For vibration-free work at high speeds.

The triple slit, hardened steel MICROMOT collets cover 1, 1.5, 2, 2.4, 3, 3.2mm (1/32, 1/16, 5/64, 3/32, 7/64, 1/8inch). The table is fitted with 3 T-slots of the 12 x 6 x 5mm MICROMOT norm. An adjustable ruler scale eases the positioning of the workpiece.

Technical data:
230V, 100W, 50/60Hz. Spindle speeds 5,000 – 20,000rpm. Table 200 x 70mm with X-Y travel of 134 and 46mm respectively, with vertical travel 80mm. Footprint size 130 x 225mm and overall height 370mm. Weight approx. 7kg.

The clamping blocks depicted are included too, but not the workpiece! (nor are the 3 Tungsten milling cutters NO 27 116)

Electro-Voice TL806

The Electro-Voice TL806 low frequency loudspeaker system is a vented-box (bass-reflex) design with gross internal volume of 1.3 cu. ft. (36.8119005696 Liters) The system has been designed for use with the Electro-Voice EVM12L 12 inch loudspeaker. The usable frequency range of the TL806 is roughly 60 to 1600 Hz. The efficiency of the TL806 is 6% (half-space load, 100 to 800 Hz, 8 ohm nominal impedance) and as a result will generate outputs of 6 acoustic watts at the rated input of 100 watts.

The design provides a selection of two different low frequency response curves by the optional use of a removable port cover. In the normal configuration (port cover off) the response is flat down to the lowest possible frequency. In the step-down configuration (port cover on) the response exhibits a sloping gradual low frequency rolloff but with about a one-half octave extension of low end response. The step down mode of operation is intended to be used with simple before-the-power-amp equalization to flatten the response (only 6 dB maximum boost required, equalizer details available on request).
