MW120GT Offers High Accuracy,
High Performance for Hard Turning Applications
By Larry Pellegrini
Sr. Director-Operations
Muratec's MW120 GT is designed for automated, medium- to high-volume tight tolerance turning requiring fast part cycle time. This automated CNC turning center features twin horizontal spindles and two independent turrets with eight tool stations per turret. 
The MW120GT provides the ability of producing higher accuracy and higher part surface finish on materials with hardness of more than HRC45 to achieve lower cost manufacturing in minimal space.
The MW120GT has separate bed construction
to eliminate transfer of vibrations from one spindle
to the other.

This compact machine is designed for continuous automatic unattended production and offers an accessible, operator-friendly design for safe, fast workpiece setup. MW120GT owners can expect improved part quality, 95% machine uptime, reduced total process time, reduced in-process inventory, and reduced labor, setup, jig, and tooling costs.
Actual customer example: MW120GT with post process gage, A-A operation (i.e., same operation on both spindles), cycle time = 15.5 seconds for 2 parts, 1.67 Cpk requirement on ±.010mm ID tolerance with Rz6 surface finish.

Post Process Gauging Optimizes Production Efficiency
By Blake Savoy, Electrical Engineer
Are you looking for a way to optimize production time while ensuring quality results? A post process gauge, often referred to as a PPG, is an excellent solution. A post process gauge is used to measure the critical features of a part after it has been machined, generally using touch probes or air sensing, with a resolution to the thousandth of a millimeter. Some common part features that a PPG is used to inspect are diameter, thickness, grooves, threads, depth of holes, length, and flatness.  When used in conjunction with a machine that has a gantry loader, such as the MW120G, the PPG process becomes part of the machine's automatic cycle. Once the PPG gauges a part, the measurements are transmitted to the machine in order to automatically offset the process of the next part when needed.

This continual compensation causes parts to remain within their tolerance specifications while minimizing the downtime associated with manually gauging and adjusting tooling offsets. Adding a PPG reduces rejects, diminishes the risk of not recognizing a part that should be a reject, and cuts the labor cost of manual part inspection without compromising quality, thus optimizing overall production efficiency.

APC Alarms
By David Smith, Field Service Engineer-Trainer
In this issue, I want to talk to you about APC alarms. Even though something as simple as changing batteries might seem unimportant, it can greatly affect the bottom line by causing down time and wasted manpower.
Problem: Whenever machine is powered down and powered backup you keep getting a . . .
"DS0300 : APC ALARM : NEED REFERENCE RETURN"
(31i controls)
or
"300 APC ALARM : Nth-AXIS ORIGIN RETURN"
(18i or earlier controls)
Cause: Servo axis absolute position retaining batteries are bad Solution: Replace batteries Explanation: Murata turning centers have two sets of retaining batteries. One set retains the absolute positioning of each servo axis. This is the information that tells the machine where it is positioned at all times.
When the machine is turned off, the batteries supply a current to the encoder which stores all the positioning information while powered down. These batteries are usually (8) "D" Cell batteries installed in (2) battery cases located on the backside of the machine.
If at any time while the machine is powered down these batteries lose their charge, all information stored on the encoders will be lost. You must then go through the process of re-establishing the home positions for all of your different axis which can be time consuming and unnecessary.
We recommend changing these batteries once a year or whenever you get a "LOW BATTERY ALARM," whichever comes first. Click here to see pictures of where the batteries are located and the procedure for changing the batteries. | |

 The End is Near!
2009 Tax Savings Ending Soon
With the recession and the 2009 tax savings ending soon, now is the perfect opportunity to save before time runs out.
Tax incentives given to businesses to help pay for manufacturing equipment under the American Recovery & Reinvestment Act of 2009 will end December 31, 2009.
What can the American Recovery & Reinvestment Act of 2009 do for your company?
- Significantly reduces you tax liability!
- Gets Uncle Sam to help pay for your income producing equipment!
How does this Economic Stimulus Plan benefit your company?
- The Government increased the Section 179 deduction to $250,000.00. This can be on new or used equipment.
- In addition, the left over balance above this $250,000 may qualify for the 50% Bonus Depreciation in the first year. This is only on new equipment.
- In addition, companies can deduct their Standard Depreciation (usually over 7 years) on the adjusted basis after the Section 179 and Bonus Depreciation.
Example with Equipment Same purchase
Cost of $450,000 in 2009: in 2010:
Section 179 Deduction: $250,000 $128,000
Bonus Depreciation (50%) $100,000 $0
First Yr. Standard Depr. $14,290 $46,013
TOTAL TAX SAVINGS $364,290 $174,013
More simply put, in 2009 if your company is in a 34% tax bracket, its actual savings would be $123,858.60. This savings could make up to 15 to 20 months of payments based on a five to seven year loan or finance lease.
For more information on the American Recovery & Reinvestment Act or for a finance quote on your next purchase, call: 877-626-9300 Ext 101 or 102 |

In Closing . . .
Thank you for reading this issue of Murata News.
We're taking a break the next couple of months during the holiday season, but we'll be back in January for the new year!
