Summit #3 Series Milling Machine

The Summit #3 series milling machines are designed to provide extreme accuracy with high reliability in a heavily constructed versatile machine. The heavy cast iron construction makes these mills the ideal choice for job shops, maintenance shops and tool and die shops, said Summit. They can be successfully used for single piece, small lot or high production applications. The large choice of spindle speeds coupled with infinitely variable feed rates provide for optimum cutting conditions in ferrous and non-ferrous metals.

"A few of the outstanding design features include; an alloy steel main spindle that is thermally treated and precision ground then fixed on high accuracy bearings; a heavily proportioned saddle assembly that travels on precision ground ways that assure rigidity and stability under extreme loads; and an automatic lubrication system that ensures consistent lubrication of the spindle. Spindle speed change is easily accomplished using the clearly identified levers and charts mounted on the column or the overarm. The feed rate is infinitely variable and controlled by a potentiometer on the conveniently located control panel," said a Summit spokesperson.

"The engineering excellence, fine workmanship, quality materials and robust specifications of the Summit #3 Series Universal Horizontal Mills assures users greater production and trouble free operation for years to come.

"Three different vertical heads are available on the #3 series mills. The 3UH offers a universal head that can be fixed to and driven by the horizontal spindle; the 3UH-POA-U incorporates a universal head that is mounted to the over-arm and is driven by a separate 5.5-HP motor; the 3UH-POA-Q incorporates a universal head with a moveable quill that is mounted to the over-arm and is driven by a separate 5.5-HP motor. The addition of the vertical head allows the

#3 series to be used as vertical mills adding to their versatility. The 50 taper allows users to use all of their standard tool holders in either spindle.

"The variable frequency drive enables immediate response to the infinitely variable cutting feed rates, in either the high or low range on the table, so that feed rates can be tweaked up or down during a cut to optimize tool life and part finish.

"The column is designed with box ways for vertical movement of the knee and the knee is designed with box ways for cross movement of the saddle. The ways are widely dimensioned to provide rigidity and reduce vibration. The infinitely variable feed motor and two range gearbox is mounted on the right side of the knee.

"The electrical controls are located on the lower side of the column in a separate box which protects them against humidity and dust. They are easily accessible. The controls are supplied with 24 volts to meet safety standards. All electric motors are protected against overloading and short circuits," said the spokesperson.
