STH6 Feature

Lathe Machine
True Slant Bed - Heavy Cast Base	One piece cast iron foundation is a true 30 degree slant bed casting, providing large mass in a small footprint. More mass means higher rigidity and better heat dissipation.
Slant Bed Design	A slant bed lathe allows for better chip flow. A slant bed lathe can handle a large volume of chips, while protecting the ways from chips and debris. Also provides easier access to chuck and cross-slide - making set-ups easier and faster.
1.89” Spindle Bore	Generous spindle bore allows for easy pass through of large diameter stock. Easy access for optional pneumatic or hydraulic chuck.
Solid Box Ways	Traditional way design has several advantages - including the ability to take heavy cuts and handling heavier work pieces. Induction hardened and ground for precision and long life.
Manual 6” Chuck	With American Standard A2-6 spindle nose chuck mount. Manual 6” scroll chuck is standard option - adaptable for pneumatic chuck or 5C collet holders.
4-Turret Tool Post	Electric indexing tool post allows for convenient tooling changes, by using lower cost standard size tooling. Useful in small part run operations, machine shops and prototyping - situations where you are changing tooling more often.
Extra Tool Gang Plate	Located directly behind the turret tool post, this BONUS gang plate allows you to add additional tooling to your operation. Not limited to tooling you can fit in the 4-tool turret tool post.
Tool Box and Tools	A set of the basic tools required for maintenance are included with this lathe. Gives you what you need to get  up and running and for routine maintenance.
Manual Tail Stock	With nearly 12” of travel on the tail stock and 4” of quill travel, this manual tail stock expands the capabilities of the STH6 to allow for turning extra-long stock or work pieces.
Foundation Pads	Heavy machined leveling pads that adjust the height to keep your machine aligned and balanced. Solid multi-point contact with shop floor reduces vibrations and increases accuracy.
Drive System
5 HP Servo Spindle Drive	Plenty of power to match the machine’s capacity. Provides higher torque - PLUS, rigid tapping and spindle positioning capabilities.
50-3000 Spindle Speed Range	Servo driven spindle provides rapid speed changes, from 50 to 3000 RPMs in a single speed range. No need for changing gears or belts. Constant torque rise, even at low RPM are assured with the servo drive.
Feed Rates: 320 IPM on X / 480 IPM on Y	Faster speeds equals higher production rates. The Siemens industrial control, and axis servo drive system provide the power and control that allows for higher speeds - many times faster than competitive systems.
PMI Ball Screws	World-class standard ball screws that efficiently transmit rotary motion to linear motion.  This allows for high-speed, highly accurate axis movements. Accurate ball circle diameters along full length of ball screw assures consistent drag torque and low noise.
Safety/Operation
Ergonomic Control Panel and Operator Interface	Machine control panel adjusts and rotates up to 90 degrees. High tactile buttons, manual pulse generator, and convenient cycle start buttons improve operator convenience, efficiency, and safety.
Auxiliary Cycle Start	Easy access buttons allow the operator to operate pneumatic or hydraulic chuck with the push of a button. Having a second E-Stop within easy reach also adds to the safety features of this lathe.
Manual Pulse Generator	Handheld pendant that allows the operator to be independent from the main control panel. The rotating knob generates pulses that are sent to the machine control, allowing the operator to move the lathe in a pre-determined distance with each click of the knob detent.
Automatic Lubrication System	Lubricates all wear points during machine operation at continuous time intervals. Benefits include: reduced labor, material costs and significant extension of bearing life.
Programmable Coolant System	Control coolant flow at the control panel using standard M-Codes. Cycle times can be significantly reduced, while feeding and cutting speeds can be significantly increased. Proper cooling extends life of cutting tools.
Work Light	Focused lighting elements increase operator efficiency and reduce fatigue. This light is flicker resistant, waterproof, and resistant to both cooling and lubricants. It is also resitant to impacts and vibrations.
Tri-Color Alarm Light	Green light turns red when control alarm recognizes a machining error or machine malfunction. An operator standing away from the machine is visually alerted by the activated alarm light when machining cycle is finished or machine errors out.
Siemens 808D CNC Control
Closed Loop System	System directly monitors motor position and velocity in real time. The system then automatically makes corrections to assure correct tool positioning. High accuracy and maximum parts quality ensure a minimal rejection rate. Also assures smoother surface finishes.
Siemens Servos and Drives	Achieves rapid acceleration and higher speeds - maintains high torque throughout speed range. Motor is highly efficient - and it stays cool. Quiet at high speeds while having a vibration free operation.
Ideal for CNC Beginners	Ideal for entry level CNC users, the innovative, integrative start-GUIDE from Siemens provides an on-line digital help function on every screen. Helpful instructions are available anytime - at a push of a button.
Simple & Intuitive Interface	Well designed conversational programming functions and Wizards from Siemens, that help streamline programming at the control panel. All Siemens 808D controls come standard with this SINUMERIK Operate BASIC functionality.
Compact and Robust	Industrial panel design with hardened features is ideal for harsh environments. Small compact design matches smaller machines tools like the AutoMate CNC line.
USB Connector - Easily Handles Large Files	This unique Siemens function allows for the streaming of large program files direct from a USB. Large files are no longer a concern - other CNC systems lack this robust level of functionality.
Built-In Helps	Several Siemens provided “assists” help streamline programming functions. One example would be Hot Keys. With the Hot Key function, machine operators can easily access commonly used screens using operator defined hot keys.
