 |
VMC-127H
 Shorten the Distance Between Work Piece and Operator
1. An indented foot space allows operators to get closer to the table and work piece.
2. The location of the Y-axis servomotor is at the back of the machine to shorten the distance between the operator and table for
greater work area access.

Innovative Design Enhanced By Scientific Analysis
Finite Element Analysis is used to supplement traditional machine design by strengthening areas generally overlooked by designers. |
 |
Rigid Spindle Design
1. Heavy duty precision spindle bearings.
2. A direct drive, 50-taper, 10,000 RPM spindle headstock mounts to a linear guide way Z-axis slide, enabling a rapid traverse speed of 30 meters/min (1.180 in/min)
|
 |
Superior Structure
1. C-Frame column with heavy duty roller-rail guide ways on the Z-axis.
2. The VMC-127H uses a hydraulically activated nitrogen counterbalance system instead of conventional counter weights to help minimize vibration during rapid Z-axis movements.
|
 |
Temperature Control System For Each Ball Screw
1. All ball screws are air-cooled through the center to reduce thermal growth and enable better machine accuracy.
2. X and Y-axes have hardened way construction. The Z-axis uses roller-rail linear guide ways.
|
 |
Ball-Bar Testing
Each machine goes through telescoping ball-bar tests to check contouring accuracy and uncover any geometric errors. This testing ensures the machine structure is both square and parallel. |
 |
Calibration with Laser Interferometer is Performed and Certified by PMC
All of our machines are calibrated according to the "VDI 3441 3σ" standard. Calibration is performed for full travel length for each axis. Each measurement is taken six times to ensure the most consistent and accurate readings. . |
 |
Hand Scraping
To ensure consistent high quality. each slide way is hand-scraped. Each axis saddle has Turcite material on it and a special "*" design is used along with a "Z" pattern for efficient oil troughs. There is an excellent distribution of oil to all axes, so settling time after rapid movements is eliminated, and stick-slip during cutting is minimized. |
 |
Friction Coefficient Testing
After the exclusive "*" pattern hand scraping, technicians inspect the results using torque measurements to make sure the ratio of contact region is over 50% and it is uniformly distributed. In addition, all contact points have a similar size, which helps maintain even static and dynamic resistance over the entire travel range of each axis. |
 |
Coolant Thru Spindle (C.T.S.)(Option)
Coolant through the spindle with pressure of 20-bar(150 -psi) effectively reduces tool wear because of heat and the slow evacuation of metal chips.
CTS with higher pressure is also available.
|
 |
Simple Tool Length Measurement (Option)
Used mostly for drilling and tapping, the Metrol system T-208 probe only measures tool length, This simple cost effective system greatly reduces tool length values once the probe touches the tool.
|
 |
Linear Scales for lmproved Repeatability (Option)
Linear scales on the X and Y-axes offer an exceptional positioning accuracy of up to 0.005mm over the full axes strokes. Only Heidenhain linear scales with a thermal behavior similar to that of the machine are selected so that thermal expansion can be compensated for further enhanced repeat-ability. Sealed encoders with durable aluminum housings offer improved reliability and service life.

Forceful Cleaning Spray-Gun
Equipped on the right front side of base this unit along with the assistance of a high-pressure coolant and air mixture helps increase table cleaning speed.
|
 |
Automatic Lubrication System
All AGMA machines use a pressurized central lubricating system. The PLC controlled system allows all three axes to be lubricated evenly to maintain accuracy and prolong machine life.
|
 |
Oil Circulating Cooling System for Spindle
A high efficiency spindle cooling system dissipates running induced heat generation in order to maintain spindle accuracy and prolong spindle life. |
 |
Electrical Cabinet
1. All electrical components are in compliance with all safety rules and regulations.
2. All components inside the cabinets are clearly labeled and identified for ease of troubleshooting.
|
 |
There Chip Auger Design
Instead of using a costly chip conveyor, the special three-chip auger system efficiently removes metal chips produced during machining.
|
 |
Hinged-Belt Chip Conveyor(Option)
This allows for rapid and efficient chip removal during machining in order to maintain a clean machine.
|
 |
Pressurized Oil Distributor
Lubricating oil is evenly distributed to the sliding surfaces of the machine by using Showa oil distributors along with hard-plumbed. low maintenance oil lines.
|
 |
24 Tools Magazine
A rapid arm-type tool changer is driven with a precision cam, maintaining tool changing accuracy of 0.01mm, which in turn will help maintain long-term spindle-clamping accuracy.
