The MWL701 Jack and Translation Stage has been designed for the vertical and horizontal positioning of crystal orientation devices and samples. The jack assembly consists of three rugged ball screw jacks and durable aluminum housing with a track of 2" width (50 mm). The stage and jack assembly will easily accommodate a weight load to 110 lbs (50 kg). Precise positioning of samples is easily accomplished with the MWL 731 6-axis, joy stick controlled motor driver which is required to operate this stage. Horizontal range of travel = 4" (10 cm), vertical range of travel = 2.7" (6.7 cm).

| The MWL703 Motorized Orientation Base with removable front Barrel Holder assembly. The Barrel Holder holds the sample safely in the x-ray beam while the Motorized Orientation Base tips (orients) the crystal into its final, precise alignment. Then the Barrel Holder can be removed (by loosing the two horizontal screws on either side of the Barrel Holder) and pulled out of the Orientation Base. The Barrel Holder can then be mounted in a machinist "V" block (not shown) and bathed by a water-cooled diamond saw or immersed in oil during electrical discharge machining as the surface is sawn along the oriented plane that is perpendicular to the Barrel axis. [The 3-axis stage can not do this as it has precision electric motors permanently attached that are not designed for such rough service]. Further product details: The Power Pod contains two DC motor driven Allen wrenches in the power pod that tip the front plate along horizontal and vertical axes. The motors are torque limited to eliminate damage. The automated barrel holder base is mounted on a standard x-ray track (as shown). The spring loaded and motorized Allen wrenches engage the barrel holder automatically when the barrel holder is inserted into the power pod. The barrel holder can accommodate crystals to a maximum weight of 2.2 lbs (1 kg) and can tilt the crystal plus or minus 7 degrees on both orthogonal axes. This unit is designed to operate with the MWL731 automated motor driver which can produce a 0.04 degree step size with adjustable speed of 0.04 to 0.8 degree/second. The power pod can be manually rotated through 360 degree about the barrel holder axis. A manually adjustable allen key locks the front plate of the barrel holder when orientation has been completed on a crystal. This is the ideal way to mount a crystal in preparation for a final orientation cut on an external saw. | ||||||||||||||||

The MWL705 Three-axis Rotation Goniometer provides remote alignment of crystal samples within a radiation enclosure. This goniometer is ideal for sample manipulation over large angular ranges. The MWL705 is operated through the 6-axis MWL731 motor driver.

| The MWL731 6-Axis Motor Driver with joy-stick control has 6-axis capability to drive 12 or 28 VDC motors at up to 2 amperes per motor. A joy-stick controls the motors a pair at a time. The rotary switch allows selection of one of three of the pairs. The motor speed is varied by changing the rate at which full voltage pulses are delivered to the DC motor. This ensures full motor torque even at low motor speeds. Light emitting diodes on the joy-stick pod indicate the return motor current. | ||||||||||||||||
