High ram travel speeds are desirable for final mixing, re-milling, and for ram "bumps" that are typically used late in the masterbatch mixing cycle.
High accuracy is guaranteed by means of the dynamic RAM compensation system and optimal guiding system, both vertical and RAM travel. They are equipped with four linear guides and are symmetric to the column.
Other features include: 7-inch horizontal ram travel; 2.75-inch diameter horizontal ram; quick change head and air motor; standard l/4-inch or optional 3/8-inch long collets; 5-wire control--retrofit to Bowman or Kangaroo wiring; air dryer purges cutter interior motors; and four ram sizes provide 1 1/2 to 4-inch vertical travel.
Ram travel (Z-axis) is 12", while orbit travel is 400".
* ability to allow a mid-stroke ram travel (for ram cleaning or batch turnover), reducing overall cycle time;
It also features an EDM-specific display for ram travel, definable retract point and relays, simultaneous absolute and incremental display for table positioning, approaching-zero indicator, and bolt-hole calculator.

This travel distance was divided into four equal fractions of one-fourth inch (0.635 cm) each for four different zones for measuring viscosities at four different ram travel speeds (shear rates) (ref.
Today, users of press brakes want to control as many machine functions as possible; computer-controlled functions include: * Regulation of the stroke (amount of ram travel used for a given job).
Ram Travel (Inch): 12 Number of T-Slots: 3 Maximum weight of work piece: 750lbs.
A hydraulic ram travels laterally in a channel built into the bottom of the hopper and pushes material into the rotor.
