Description

I am amazed at the stability and accuracy of the DMC-III. I can use it to engrave 1mm letters on a gold plate with extremely high precision. The machine is better than any system in the market, including Minitech.

*1 This micro-step controller was developed by ACT. We guarantee no lost-step errors in the normal operation. We have tested these machines at full speed (rapids rate) in all axes continuously for many hours at a time; the motors did not get hot at all, nor was there any loss of position. There are 5 processors in each controller: one for each of the three axes , one for the spindle motor control and one for the coordination of all motions. The electronic system is thoroughly tested subject to temperature variations and vibrations for reliability and lasting life. Please see our \\\\\\\"the technologies page.\\\\\\\" page in our website for details.

*2 Options to choose different size of motor with up to 50,000 RPM maximum speed. Any off shelf small spindle can also be easily installed in the machine. We can provide the custom made fixture to secure any spindle user preferred on the machine.

*3 4th axis rotary table is a high precision table with zero backlash, 7.2 arc sec (0.002 degree) resolution.

Ball Screw Cover Installation

The ball screw cover can be installed on the x axis to protect the ball screw and rails from debris during the cutting. The travelling distance of x axis will be reduced when the cover is installed. The cover can be easily take out and put on as needed. You need to take out the cover for \\\\\\\"homing\\\\\\\" action.

Instruction for the installation

  • Peer the plastic and place the sticker on the machine frame as shown in Fig 1.
  • The cover is attached to the sticker with fabric cloth as shown in Fig 2 which can be easily put on of off.
  • The plastic guided way is placed inside gap as shown in Fig.3
  • The protection covers the ball screw and the rails as shown in Fig 4.

Compact PC with installed Mach3 CNC software for the turnkey operation. The PC requires 25 pins parallel port with Window XP operation system. User can select to use their own PC if you are familiar with Mach3 software.
Standard ER11 spindle for tool bits up to 1/4\\\\\\\" in diameter. User can choose from. ER11 is a smaller spindle with higher precision and higher manufacture cost. We offer the same price as ER16 spindle to our customer.
Standard ER16 spindle for tool bits up to 3/8\\\\\\\" in diameter. User can choose from. We allow user to choose either ER11 or ER16 spindles for the same price.
Optional small high speed brushless digital motor drive M2 (2\\\\\\\" diameter) for spindle driver. The motor speed is 1,000 to 12,000 rpm.
Small high speed motor,M2, connects to the spindle through pulleys and belt. The gear ratio from motor to the spindle is 2 for ER11. Therefore, it provides 24,000 rpm for ER11 spindle maximum speed.
Standard high torque motor, M3 (3\\\\\\\" diameter) connect to spindle through pulleys and belt. The standard M3 motor speed is 1,000 to 6,000 rpm. The gear ratio from motor to the spindle is 2 for both ER16 and ER11. Therefore, it provides the maximum speed of 12,000 RPM for both ER16 and ER11.
Large precision T slot table built by cast iron for precision and rigidity. It provides large working space with the simple operation instructions posting on the table for users convenience.
This is the most advanced digital controller for all 3 axes and the spindle motor speed control integrated into a single box. The dimension of the box is 22\\\\\\\" X 7\\\\\\\" X 3.5\\\\\\\". There are 5 CPU micro-process chips inside to achieve 2 micron motion precision and the variable spindle speed. We have spent 4 years to optimize and finalize this product through thoroughly tested. The regular power supply (120V or 240V) is used. This controller box is integrated with the machine into a single piece of the machine. No any additional box need to be connected to the machine except the PC. please refer to the technologies page for the details.
We guarantee the product for lasting life.
High precision (0.00008\\\\\\\") infra rate optic sensors are used for home switches for all axes. This is a non contact sensor which can provide precision and reliability for many years.
The emergency stop button on the machine to shut down the system.
Showing the input ports for DMC-III machine controller box: a 25 pins parallel port (printer port) for the PC, 4th axis port which can also be used for the tool sensor or digitizer inputs and Aux port for the liquid cooling pump system.
4 heavy duty handle bars provided to bolt on the machine for easily moving.
Custom made fixture to secure any spindle user choose, such as NSK 50,000 rpm spindle, to the DMC-III machine.
Optional item to install liquid coolant pump system. The coolant pump on and off is controlled through CNC program.
The machine is bolted on a wooden pallet for shipping.
