1. 3500/HWL7/HWS7/HWL12 Special Compound Slide and Spindle Module
Hydraulic driven slides for three axis of motion. Travels X-Axis-3", Y-Axis-4", Z-Axis-6". Application: Plunge mill two pads on an aluminum part.

2. Special Compound Slide and Spindle Module
Lower slide is a three-position type. End mounted hydraulic cylinder has a double rod, with one end used as an in-line adjustable positive stop. Hydraulic cylinder mounted under the saddle extends the balance of the travel, using the stop rod assembly for positive depth control. Upper slide has an internal mounted cylinder assembly. Mounted on the saddle are two 4000 belt gear driven spindle assemblies.
Application: Advance lower slide to center position, cross feed upper slide to mill face of two parts. Feed lower slide to hollow mill same two parts. Retract lower slide to starting position, retract cross feed slide and index parts.

3. HWL9/HWL15 Special Compound Slide Module
Lower slide assembly is designed to accept a ball screw and nut assembly. Upper slide assembly is designed for a hydraulic cylinder with adjustable forward stop. On this module the customer will furnish the power drive assemblies.
Application: Facing and boring.

4. HWS15 Special Compound Slide Module
Both axes are supplied with ground ball screw and nut assemblies to be motorized. Lower axis used for positioning. Upper axis has a R.H. and L.H. ground ball screw so the saddles can be moved toward and away from each other.
Application: Compound slide assembly for special lathe.

5. HWS9/HWS12 Special Compound Slide and Spindle Module
Both slide axes are hydraulic cylinder powered. Lower axis used for three positions. Upper slide rapid traverse feed, to a depth stop and retract. Spindle is a 4000 series special gear drive.
Application: Three position slot milling.

6. HWS7/4000 Special Slide and Spindle Module
Slide has DC motorized belt driven ball screw assembly. Spindle nose end designed for special boring tool holder. Spindle belt driven with AC motor and electronic variable speed controls. Slide is supplied with accordion way
covers, multiple limit switch assembly and a welded
steel angle bracket.
Application: Precision boring of parts on dial
boring machine.

7. HWL15/HWS24 Compound Slide Module
Lower slide is equipped with ball screw and nut assemblies to be motorized and programmed for three stops. The saddle has hydraulic retainer locks to secure the positions. Three HWL15 slides are machined in the saddle, two of which are supplied with ball screw and nut assemblies, the other to be lead screw powered and gear driven from customers tapping head.
Application: Drilling, chamfering, and tapping of stationary part.

8. HWV24 Special V-Type Hardened Steel Way Slide
Ideally suited for your precision boring applications. Available in sizes 7" to 24".

9. DC12/HWS15/HWS18 with Rotational Sub-Plates
Special three-axis assembly, complete with programmable controller capable of two axis simultaneous operation. Travels, HWS18 Axis-28", HWS15 Axis-19", DC12 Axis-12", with precision ground ball screws and preloaded nuts in both hardened way axes.
Application: Special lathe compound for turbine machining.

10. 8000C-X3M-50-G-D3 Special Motorized Vertical Travel Spindle Mounted to HWS32/HWS32
Travels in Z-Axis-20", X-Axis-12", Y-Axis-28". Precision ground screws and preloaded nuts — all axes. 15 H.P. spindle drive with two-speed manual transmission.
Application: Three-axis machining with customer engineered and assembled CNC control.

11. HWS24/HWL20/4000 Special Slide and Spindle Module
Lower axis slide has internal mounted hydraulic cylinder assembly. Top slide is a low profile base with ball screw assembly and hydraulic drive motor. Four spindles are in a cluster, each pair driven by an electric gear motor.
Application: Milling four separate surfaces of a part at one time.
