SL280 Features

Lathe Machine
Uni-Block Cast Iron - True Slant Bed	Single piece, true slant bed and foundation casting.  Provides large mass in a small footprint. More mass means higher rigidity and better heat dissipation.
Slant Bed Design	This 35 degree 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. Slant bed offers improved operator access to chuck and work table - easier for set-ups.
1.89” Spindle Bore	Generous spindle bore allows for an easy pass through of large diameter stock. Easy access for optional pneumatic or hydraulic chuck.
Full Enclosure	Machine is completely enclosed with a sliding front access door and easy access panels on the tailstock end and machine back side. Coolant and chips are enclosed and properly recycled. Electromagnetic lock keeps operator safe.
Gang Tool Plate	A nice set of tool holders is included. Gang tool turning is the fastest, simplest and most economical of turning methods. Set-up is extra convenient with the slant bed design.
Pneumatic Collet Closer w/Foot Actuator	Collet system is air actuated and can be operated from the auxiliary panel or with the foot actuator. Easy access actuator options improve efficiency and safety for the operator, while reducing operator fatigue.
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.
Foundation Pads	Heavy machined leveling pads which adjust the height to keep your machine aligned and balanced. Solid multi-point contact with shop floor reduces vibration, and increases accuracy.
Drive System
5 HP Servo Spindle Drive	Plenty of power and torque to match the machine’s capacity.  Capable of rigid tapping and spindle positioning.
50-3000 Spindle Speed Range	Infinitely variable speed ranges, from 50 to 3000 RPMs. No need for changing gears or belts.
Schneider Electrical Components	One reason we can offer an 18 month machine warranty is because of the recognized quality and reliability of Schneider Electrical components. Highest reliability rating - highly efficient design reduces power usage.
Bosch Rexroth Ball Screws	German designed and built, world-class standard ball screws - efficiently transmit rotary motion to linear motion; allowing for high-speed, and highly accurate axis movements. Accurate ball circle diameters throughout length of ball screw assures consistent drag torque and low noise.
1100 IPM Feed Rates on X and Y	High quality linear guides and ball screws turn this lathe into a high speed machine. The Siemens industrial control and servo drive system provide the power and control that allows for higher speeds - many times faster than competitive CNC lathe systems.
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 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 predetermined 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 and 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 reduced significantly, while feed and cutting speeds may 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 resistant to impacts and vibrations.
Tri-Color Alarm Light	Green light turns red when the 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	A closed loop system directly monitors axis 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 - with 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 the push of a button.
Simple & Intuitive Interface	Well designed conversational programming functions and Wizards from Siemens 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 panel design is well matched to AutoMate CNC Lathes & Mills.
USB Connector - Easily Handles Large Files	This unique Siemens function allows for the streaming of large program files direct from a USB.  Machining large program files is no longer a concern with this unique Siemens level of operation.  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.
