Centroid has been building CNC Mill and Lathe Controls in Howard, PA for over 30 years. Now available is the Remedy R21i Industrial built by Remedy for our Industrial Machine tool applications and it is the only Centroid Control offered on Remedy Machine Tools. The name indicates R for Remedy, year new of 2020+, Windows operational software, and rugged Industrial hardware for extended reliability. Remedy CNC controls are built as heavy duty industrial controls for reliability and endurance offering years of hassle free operation. Using only industrial grade Computer hardware that is designed for the harsh environment’s which are found in shops and factories.
We provide a complete 2 year parts and labor warranty on all “R21i by Remedy controls!

Aaeon Boxer-6600 industrial hardened PC is at the heart of our control. It has a high speed processor with fast boot up and a simple design.
Aaeon Boxer-6600 industrial hardened PCOur control processor is securely mounted in a heavy duty cast industrial housing with aluminum fins improving heat dissipation, this HD build creates a stable foundation and improves shock resistance from the cutting operations of the machine tool. 24 Volt operation means Extremely low power consumption and this reduces or eliminates heat in the PC control housing for longer life. Our Control box has large fans and exhaust ports with easy change filters. Quality parts which build years of reliable operation.
Windows Operating System:
Using Windows basic, reduces unwanted software items that are not related to the operation of our R21i Control. We make sure that only the needed software is loaded into our controls. High speed Intel processor and only industrial components are in the R21i control.
LCD Sizes:
Remedy can now offer both 15 and 19 inch Color LCD Screens. Touch screens can be toggled on or off for customers that may have problems with oil and/or coolant on the operators fingers causing a false double hit. The LCD is a separate unit form the computer making it easy a (4 screw 1 plug) remove and replace servicing item. Should you ever have a problem with our R21i control most parts are plug and play, easy swap out by you the customer. Of course we are always available for your support – and 2 Years are completely covered!
Our control is listed to operate from 0–120 degrees. Our computer control as stated operates on very low voltage (24 Volts) which does not create heat. Heat being a loss of energy, over time it also causes deterioration of the electrical components inside the computer and control cabinet. Using our locally sourced industrial grade PC hardware is only one of the many improvements in the Heart of the Remedy R21i industrial control.
Control system cooling:
Air flow is very important to the life of every control and we have huge 8x8" or 12x12" industrial fan and vent units both with replaceable filters are in our control and magnetics cabinets. High air flow of 150 CFM will keep everything inside the our control cabinet cool and our filters will keep it clean. In Heavy duty Yaskawa controls we offer a 12x12 Fan and vent having 300 CFM of air flow or our choose our AC Cabinet chiller option.Our Breaking Resisters are externally mounted with a Heat shield so no additional heat is created inside our magnetics cabinet.
OPTIONAL: Remedy offers an AC Heat exchanger for machines that are not in climate controlled environments. We understand that it is important to keep all electronics under 100 degrees 24/7 for longer life and proper operation. This AC unit is also field retrofittable by your Remedy Service team for owners of our machine tools or if your needs change and you require this option.
A huge 8 gigabyte SSD and full size mSATA drive will allow you to keep hundreds of files (programs) at the machine, and easily back them up using our multiple USB ports, or use the standard LAN port. This Solid state hard drive eliminates problems from moving parts which was the case in older hard drives and these are also improvements from later flash cards that were used.
For advanced 3D machining we have high speed look ahead with super fast fiber optic closed loop Delta drives and motors. The flexibility of the Remedy R21i control system allows us to control small to heavy duty motors and to drive all size mills, machining centers and Lathes. Remedy offers Delta axis motors and drives, Spindle inverters as standard equipment on many of our machines. Yaskawa electronics is offered on our largest Heavy Duty Machining Centers.
Remedy Improvements to a Better Design:
Industrial Hardened Control with color coded electronics. All “R21i by Remedy” control components are designed for ease of service by the customer, local service technician and/or your Remedy dealer. Remedy schematics are easy to follow and show parts and numbered wires, all with power related color coding making it easier following and to locate items. We use circuit Breakers everywhere in our control, as fuses are old school. International OSHA and NFPA Color coded wiring and hardware: 24 Volt DC are (BLUE) Blue/white is 24 common, 110 VAC are Black - 110 VAC common are White - 110/220 VAC are Red Ground is Green and G/yellow stripe. We have followed the industrial electrical format making our control one step closer to OSHA code acceptance by design.

Standard equipment are Delta: Motors, Drives and Inverters. Each Axis has a single drive reducing costs over all-in-one multi axis drive units. We keep all Delta items in stock here at the Remedy PA facility for fast replacement and reduced service times if it is ever needed.
Your machine tool uptime is very important and is part of our quality commitment to you.

An affordable, accurate alternative to expensive Renishaw touch probes.Renishaw touch probes
The CENTROID DP-4 CNC Touch probe is designed for Probing
(part setup, zero location setup, and CMM type measurement of part
geometry, component/fixture/work piece setup, inspection and 3D or 2D
The DP-4 CNC Touch probe is made of stainless steel and is made in USA
with patented technology. Unlike other probes, the DP-4’s low trigger force
allows the use of small styli for maximum detail and accuracy. Commonly
used on Milling Machines, Machining centers, Router and Turning centers.
The DP-4 is a state of the art mechanical design and is compatible with
most any CNC control that has a PLC input for Probes. Previously sold
exclusively for use with a CENTROID CNC control, now the DP-4 is
available for use with other CNC controls such as Fagor, Haas,
Fanuc, Fadal, Mazak, Mach3 and many others.
DP-4 CNC Touch probe is made in USA with Centroid patented technology
The bottom photo is the original, the reproduced part (in blue wax) and G code back plot graphics of the digitizing data that was automatically created by CENTROID's CNC Digitizing directly on the milling machine that cut the part. The data you see on the screen is not manipulated raw digitizing data generated by the control, no cad/cam was used in this example. However if more extensive editing to the shape is needed it is easy to export the data to a CAD/CAM system for further editing. Note: Files can be transferred to other centroid equipped machines as well. So you can digitize on one machine and cut the digitized file on multiple machines at the same time for mass production.Example
ExampleTT-1 Conductive tool measurement.
Set up your tools in a quarter of the time that it would normally take! If you often machine short-run parts and are always setting up and tearing down for a new job, the TT-1 Auto tool set will save you time while more accurately setting your tool height offsets. With the TT-1 you can create more parts per hour since the tool setup is so much faster. You'll even save time when you have to replace a dull tool with a new one in the middle of a job. The TT-1 is completely automatic. Press "measure" and the tool will automatically touch off the TT-1 and set the tool height offset in the tool library.
ExampleCoordinate System Rotation: CSR matches the machine to your vise.
This option is made specifically for the machinist who is constantly breaking down and setting up new fixtures and vises or very large parts. By simply touching off two points along the edge of your fixture, the control will automatically rotate the machine coordinate system to match your fixture/part angle, saving you time and money. With CSR your vise, fixture or part does not have to be lined up square with the machine, CSR eliminates aligning the vise with an indicator. CSR is very accurate. Job set in minutes. Both automatic (with the CENTROID DP-4 Probe) and manual touch off set up can be used.

Motors and Drives:
Lathe controls are normally 2 axis with the additional tool changer. The 3rd axis is normally used for side machining where the spindle is used as a rotational C Axis. Remedy does not offer this ability at this time and may in the future on Centroid controls. Remedy uses Delta motors, and drives on our lathes as standard equipment and they mirror the Mill control hardware.
Dual hand wheels:
Easily move your Z or X axis with our dual hand wheels.
Spindle Motor:
The spindle motor is inverter and encoder controlled so that we can exactly control the RPM and spindle and also position the spindle for quality surfaces in all threading cycles. Our High power AC Spindle motor provides smooth speed changing throughout the entire RPM range.
