Page 10: Standard Features
1.1.2. Wet Cut The ASR1200 rotary stage has a standard wet cut rotary union that is used for fluid delivery (@ 100 psi max pressure) in wet laser cutting applications. A 1/4" NPT tapped hole is supplied on the rear of the rotary to allow for connections of different length pressure vessels depending on the tube length being cut. -
Page 11: Optional Features
1.2.1. Mounting Plate ASR1200 stages can be configured to include a mounting plate that can use either M6 or 1/4-20 bolts. The bot- tom of this mounting plate is precision machined and verified for flatness. If the mounting plate is not selected, a custom mounting option can be attached using the (Qty-4) M6 tapped holes in the bottom of the stage. -

Overview ASR1200 Rotary Stage User's Manual 1.5. Safety Procedures and Warnings The following statements apply throughout this manual. Failure to observe these precautions could result in serious injury to those performing the procedures and damage to the equipment. This manual and any additional instructions included with the stage should be retained for the lifetime of the stage. - Page 15 ASR1200 Rotary Stage User's Manual Overview Do not expose the stage to environments or conditions outside the specified range of oper- ating environments. Operation in conditions other than those specified can cause damage to the equipment. The stage must be mounted securely. Improper mounting can result in injury and damage to the equipment.

Page 17: Chapter 2: Installation
Allowing the stage to stabilize to room temperature will ensure that all of the alignments, preloads, and tol- erances are the same as they were when tested at Aerotech. Set the stage on a smooth, flat, and clean sur- face. -
Page 18: Preparing The Mounting Surface
The mounting surface should be flat and have adequate stiffness in order to achieve the maximum per- formance from the ASR1200 stage. When a stage is mounted to a non-flat surface, the stage can be dis- torted as the mounting screws are tightened. This distortion will decrease the overall accuracy of the stage. -
Page 19: Securing The Stage To The Mounting Surface
(see Figure 2-2). The stage must be mounted securely. Improper mounting can result in injury and damage to the equipment. Figure 2-1: ASR1200 Stage Showing Mounting Plate (Top View) Figure 2-2: ASR1200 Stage Without Mounting Plate (Bottom View) www.aerotech.com... -

Page 21: Changing Asr Workholding Devices
2.5. Changing ASR Workholding Devices ASR1200 stages are equipped with an ER16 style collet. It is important that only the collets designed for a particular collet holder are used. Aerotech collet chucks are designed for use with ER collets manufactured to DIN6499 specifications. - Page 22 Installation ASR1200 Rotary Stage User's Manual Figure 2-3: Installation of Collet into Collet Nut Chapter 2 www.aerotech.com...

Page 24: Electrical Installation
N O T E : When operating the ASR1200 it is recommended that 5 psi be supplied to the collet at all times. This will act as an air purge and help prevent contaminants from entering rotary union. -
Page 25: Chapter 3: Operating Specifications
Use the system in a low vibration environment. Excessive floor or acoustical vibration can affect stage and system performance. Contact Aerotech for information regarding your specific appli- cation. Dust Expo- The ASR1200 stages have limited protection against dust, but not water. This equates to an sure ingress protection rating of IP50. Indoor use only Do not expose the stage to environments or conditions outside the specified range of oper- ating environments. -

Page 28: Load Capability
Contact Aerotech directly if part load requirement exceeds specifications. ASR1200 stages will contain a rotary union attached to the end of the rotary shaft, as pictured below in Fig- ure 3-1. A 1/4" NPT tapped hole is provided on the end of the rotary union shaft to allow for connecting a pres- sure vessel or extension tube. -
Page 29: Chapter 4: Maintenance
Although the ASR1200 is designed to be low maintenance, there are a few items that may require pre- ventative maintenance during the lifetime of the stage. This chapter will detail the lubrication, inspection, and replacement process of various components. -
Page 30: Cleaning And Lubrication
Contact Aerotech customer service for more information. After inspection and cleaning, grease the chuck taper and collet taper with a small amount of lubricant and insert the collet. Table 4-1 shows the lubricants recommended by Aerotech. Table 4-1: Recommended Lubricants... -
Page 31: Seal Replacement
4.3.1. Piston Seal Change Procedure The collet chuck on the ASR1200 is equipped with o-ring piston seals that are designed to last many collet chuck (open/close) cycles. However, due to regular wear, the seals may require replacement during the life- time of the product. - Page 32 Figure 4-3). A long pick or thin screwdriver will be necessary to remove the o-ring and replace it. Contact Aerotech for the appropriate o-ring size and type. 6. Re-insert the ringseal into the inner collet housing and tighten it into position.

Page 33: Wet Cut Rotary Union Seal Replacement
4.3.3. Wet Cut Rotary Union Seal Replacement There is a rotary seal in the wet cut rotary union that requires periodic replacement. Aerotech recommends replacing this seal before 1000 hours of stage run time. Contact Aerotech for obtaining appropriate replace- ment seals. - Page 34 Maintenance ASR1200 Rotary Stage User's Manual 1. Remove power and disconnect water from the stage 2. To access the rotary union seal assembly, first remove the water inlet fitting (see Figure 4-5). Figure 4-5: Rotary Union Hardware Removal 3. Remove the six seal assembly screws from the rear end of the rotary union (see Figure 4-5).
- Page 35 If the shaft and sealing surface are undamaged, clean both the shaft and seal assembly surfaces with a lint-free rag and isopropyl alcohol. If the shaft sealing surface is scratched (you can feel it with your fingernail), contact Aerotech customer service.
- Page 36 Maintenance ASR1200 Rotary Stage User's Manual 7. Lubricate the new seal with a generous amount of Parker O-Lube and press it uniformly into its housing. 8. Reattach the seal retainer to the end cap and tighten all screws in a cross pattern.

ASR1200 Rotary Stage User's Manual Maintenance 4.4. Wet Cut Rotary Union Removal If the rotary union shaft becomes scratched or damaged, it will be necessary for the rotary union to be replaced in order to properly seal the system. Figure 4-9 shows a view of the rotary union assembly. The pro- cedure for replacement is as follows. - Page 38 3. Remove shoulder bolt and bushing (see Figure 4-10). 4. Using two 19 mm wrenches (one on rotary union shaft nut, the other on ASR1200 shaft flats) coming in from the top of the carriage, unscrew the rotary union from ASR1200 shaft (see Figure 4-10).
