Bar Feeder

The LNS Quick Load Servo 80 S2 Bar Feeder allows for continuous machining with little or no operator intervention. With quick changeovers from one part run to another and a library of up to 500-part programs this servo driven bar feed will drastically increase productivity.

Equipped with an automatic diameter changing system, centerline and bar loading fingers adjust automatically as the new bar diameter is entered, no manual adjustment is required reducing changeover time to a minimum. The LNS servo motor control technology guarantees accurate bar feedout control with or without turret help and prevents hitting the turret with its soft touch positioning.

 

Bar Puller

Royal®Compact CNC Bar Puller with ¾″ shank. Easily automate your TCSi with a compact bar puller. CNC bar pullers are inexpensive and require minimal setup, improve productivity and free up operators to handle other tasks.

 

 

 

Collet Chucks

ROYAL QUICK-GRIP™ PULLBACK CNC COLLET CHUCK. Traditional pullback design utilizing Royal QG-65 collets allow for a bar capacity of 2.66” and runout on the closing angle within 0.0002" TIR.

ROYAL QUICK-GRIP™ PULL-TO-A-STOP CNC COLLET CHUCK. Adjustable stop guarantees precise, consistent z-axis part positioning and enables very aggressive cutting. Utilizing Royal QG-65 collets allow for a bar capacity of 2.66” and runout on the closing angle within 0.0002" TIR.

ROYAL LOW-PROFILE 5C PULLBACK CNC COLLET CHUCK. Traditional pullback design provides a simple, low-cost method for utilizing popular 5C collets, guaranteed to run within 0.0002″ TIR. Compact dimensions allow for superior tool clearance and Z-axis travel.

 

 

Part Catcher

The fully programable TRAK Part Catcher is deployed to catch a finished part as it is cut off to aid with unattended machining. The parts are collected in a bin for easy access while the machine is running.

 

 

 

 

Oil Skimmer

The TRAK Oil Skimmer is operated by a button on the control panel or may be integrated into your program with the use of M code.

 

 

 

 

High Pressure Coolant

The TRAK high pressure coolant system allows coolant at 220 psi to be delivered directly through the turret and cutting tool efficiently dissipating chips and heat from pockets and holes during machining. This greatly enhances cutting performance, accuracy, surface finish and tool life.

 

 

 

 

Transformer

The TRAK Transformer for the TC820 transforms from S/B 208v to 408v, factory mounted in an enclosure on the top of the machine.

 

 

 

 

Chip Cart

Chip cart that fits under the chip conveyor to collect chip remains. Wheels, coolant drain and dumping system for ease of use.

 

 

 

 

Toolholder Kit

Bolt-On Toolholder Kit; includes 8 wedge clamps for 0.75″ tooling, 3 boring bar holders with 1.25″ bore, 1 slide tool holder and accompanying coolant fittings.

 

 

 

 

TRAK® USB Memory

The USB Memory option consists of an industrial-grade Delkin® Thumb drive. This device is unsurpassed for reliability and speed of file access and is the storage of choice for our own software engineers.

 

 

3D Simulation (P25)

3D Solid digital twin of your part, faithful in every programmed detail. You can check your program by close inspection of each detail using the touchscreen operation of the 19″ screen of the SINUMERIK ONE.

CNC Memory, 5.1 GB (P12 & P77)

A combination of Siemens options that, together, adds internal memory to the SINUMERIK ONE to bring in and integrate large files (such as CAD and CAM). Extends the internal CNC memory by 1.8 GB.

DXF Reader (P56)

Open DXF files on the SINUMERIK ONE to easily transfer data into your program. Program faster and reduce errors on programming dimensions. Open and use elements of multiple DXF files in the same program. Works within all the programming methods. Easily command specific features from drawing elements. Set your own part reference independent of the drawing origin.

Handwheel Run (M08)

Run the programmed moves by turning the handwheel. You control the feedrate by moving the Manual Pulse Generator on the control panel and the actual programmed path is moved. Adjust the relationship between the handwheel turns and the feedrate with 4 different resolution settings. Seamlessly go between Handwheel Run and fully automatic CNC run. Great for setups and for confidence making that first part!

Execution from External Storage (P75)

Enables the use of an external memory device for running and editing programs. Allows your memory device to function like an expansion of your internal SINUMERIK ONE memory, without any restrictions on programs, subprograms, commands or even transferring to another machine.

Simulation Run During Machining (P22)

3D Solid model graphics real time while running a program. It is a great way to check the progress of your job, especially when you are running a lot of coolant.

ShopTurn (P17)

True conversational programming you can do right on the shop floor. Write complete part programs or insert a feature within another program. With guidance from Animated Elements, Tool Tips, Dynamic Graphics, Canned Cycles and Context-Sensitive Help to guide you can create programs with ease. You won’t have to go back to the person who programmed the part to fix or add to your program.

Residual Material Detection (P13)

The SINUMERIK ONE automatically recognizes Rest Machining situations. Simply call up the Residual Machining canned cycle, enter a few simple inputs and the control does the rest.

Match the tool to the operation for fastest machining: large tool for hogging, smaller tool for regions the large tool won’t reach. Multiple Residual Machining cycles in the same feature gives you the flexibility to minimize cycle times.

Access MyMachine OPC UA (P67)

The OPC UA (Unified Architecture) standard is particularly suitable for data exchange across different levels as it is independent from specific operating systems, has secure transfer procedures and better semantic description of the data.

OPC UA not only makes data available, but also provides information about the data (e.g. data types). This enables machine-interpretable access to the data.
