The Mini-Max (GT-30) is a flatbed design gang lathe with a footprint of 52” length and 44” width. This small footprint lathe has a Servo C-Axis Spindle motor and can deliver rapid duty cycles. The electrical component suppliers provide the highest-grade hardened CNC controls, liquid-tight motor cables that are available for machine tool manufacturers. This 5-axis system is from GSK CNC systems with the capability to perform indexing and interpolation functions through the use of an integrated C-axis. Servo driven spindle motors and drives have much greater low rpm torque and rapid duty cycles than vector type spindle motors and drives.

GSK 980TDi CNC Control:

GSK is the second largest CNC control builder in the world. They are producing approximately 500 CNC systems per week. The control is not a PC based system, but a hardened CNC with the software built directly into the hardware providing maximum reliability.  The modular design of the products allows quick replacement of major components if or when required. GSK provide complete CNC systems which include all required motors, drives, cables, and controls. The NEW 980TDi CNC control with updated software/hardware is a very aggressive full-featured control with 2ms block processing and programs with G-codes and M-functions. This control uses the GSKLINK bus technology, matched with 17bit absolute encoders that carry out automatic recovery of the system power-on no-block mechanical zero return, servo parameter on-line modification or servo state on-line diagnosis, etc.  We are using a servomotor and drives on the spindles to perform C-Axis functions. The system provides the best performance and number of duty cycles per minute and facilitates the use of live tools. We have available post processors in Fusion 360 for the GSK CNC controls. Standard Features: 4-Axis simultaneous control, 5-axis digital feed control, 2-axis analog feed control, LAN interface Ethernet Port, complex curve surface machining speed: 8m/min optimum machining speed: 4m/min, Max. Positioning speed: 60m/min’ max. Feedrate: 15m/min 1000 block look-ahead and spline interpolation, Excellent high-precision and high-speed interpolation, Supports macro programs (Macro B) more concise programs, Supports PLC online monitoring, edit, compile and signal follow functions, Supports multiple languages with a change of a parameter, Supports RS232, USB and network interfaces and data transfer, DNC machining and USB on-line machining, Color LCD monitor with 800 X600 resolution 8.4” or Optional 10.4”, Rigid tapping, graphic programming, run and test program by hand wheel, 208v (Range 190-240) 3-phase system electronics. 64M program space 60Mb user storage (program capacity).

C-Axis servo motor and spindle drive option:

CNC New, Inc. is offering the C-Axis servo spindle motor and drive with the GSK CNC control manufacturers. The C-Axis option with live tools can mill and turn parts off center. Slots, cross-holes, bolt-hole circles, and many other secondary processes traditionally requiring a milling machine/machining center can be performed with the C-Axis option. This spindle option provides increased duty cycles per minute for high production turning with a bar feed or loader. We are providing a 3.7 kW motor or 5 with this model lathe.

Work Holding Options:

We offer a wide range of standard work holding options for ATA-S systems. ATS-S offers both the pull-back style collet chucks, and also provides dead length (or true length) collet chucks for all models, in addition to Warner & Swasey style chucks, S style collet chucks, and a broad range of other chucks.

Machine Tool Riser Plates:

Each model of GT has a low table height from the original flat table, which has three t-slots. Original table heights of the machines are as follows. GT-30 MINI-MAX is at 45 mm or 1.77”, GT-7 begins at 55 mm, or 2.1”, the GT-10 starts at 70 mm or 2.7” center height, and the GT-15, which starts at 96 mm, or 3.77” center height. The riser plates are offered in 12” or 17” to cover the entire table for the GT-30 MINI-MAX and GT-7. The 17” riser covers the entire t-slot or the original table. We offer 14” riser plates for the GT-10 and GT-15 models. The machines original table is 24” so if you want to use ¾” tool holders on the entire travel of the models you would purchase two 12” risers that would cover the original t-slot of the machine. This flexibility allows us to install much larger live tool spindles and grinders on the machines and allows us to offer much stronger tool holders and tooling to compliment the larger motors and ball screws of the GT Series. (Optional ½” center height riser tool plate tables available on request.)

Single Bar Hydrodynamic Feeds:

CNC New is now providing a very price competitive solution for single bar hydrodynamic bar feed system. There are many benefits to operating a hydraulic system over pneumatic and mechanical systems. A hydrodynamic bar feed is safe, quiet and provides quick-change overs. This bar feeder can handle material to 1-3/4" diameter. We are offering a range of feed tubes to facilitate a broad range of sizes with less than 5-minute feed tube changeover. We are offering two sizes of Hydrodynamic systems to consider. The FB system can accommodate sizes from 4 mm to 26 mm, and the larger FT system ranges in sizes from 7 mm to 45 mm. The feed tubes are engineered to work with an 8mm range of material.

An example is that the 18mm feed tube could work with material down to 10mm diameter. These are approximate estimations and are impacted by the type of material and straightness of the bars. CNC Hydrodynamic system is 12.5' overall length and can accommodate material to a maximum length of 8.2'. We also recommend spindle liners with this item to maximize the support of the material and quiet & safe operation of the system.
