CHARACTERISTIC

 

High-Rigidity Structure

  1.  All three axes have a hardened box-way design . In addition, the spindle headstock, cloumn, saddle, base, and table are all made of high-quality Meehanite cast iron.
  2.  All slide-ways are heat-treated and precision ground to maintain high precision.
  3. Double guide-ways and a counter-balanced design prevent unexpected vibration from the Z-axis drive. which helps achieve a quality surface finish.
  4. Strategically placed ribs help enhance the spindle headstock structure. The spindle headstock also has the proper proportion of contact with the column, which creates strong spindle support.

 

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.

 

Direct-type Drive Spindle
  1. Each spindle uses angular contact ball bearings for higher speeds and greater precision.
  2. Lower noise and vibration can be expected from the direct-type drive spindle designs that can reach 10,000, 12,000, or 15,000 rpm.
24 Tools Magazine (Option)
  1. 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.
  2. A cam type mechanical magazine ensures high precision tool rotation. Using oversized tools to ensure smooth rotation tests each machine.
Enhanced Base Design

The base of the VMC-95/115 has 4-hardened ways that allow for greater stability and accuracy even with heavy loading. In essence, the design fully supports the saddle and table along the entire travel lengths of the X and Y-axes.
High-Stiffness Belt-Driven Spindle

The cartridge-type spindle enables speeds of 6,000, 8,000, or 10,000 RPM using a belt drive assembly. Bearings at the spindle nose end are well supported by a shaft sleeve and casting structure. The optimized bearing arrangement in combination with the rigid spindle headstock reduces cutting-induced vibrations, virtually guaranteeing a better work piece surface finish.
Short-Nose Spindle
  1. The 1:1 ratio of headstock to column contact surface enhances cutting rigidity.
  2. The spindle headstock has incresed rigidity due to the wide stance design of the z-axis ways and the long surface contact between the headstock and way bars. This translates into reduced cutting-induced vibrations, longer spindle life. and lower cutting tool costs.
  3. Equipped with an exchange arm-type ATC for shorter tool change time.
  4. The unique floating tool release mechanism minimizes any pressure exerted on the spindle bearings to enhance the durability of the spindle.
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 the full travel length of each axis. Each measurement is taken six times to ensure the most consistent and accurate readings.
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.
Automatic Lubrication System

All AGMA machines use a pressurized central lubricating system. The PLC controlled system allows all the three axes to be lubricated evenly to maintain accuracy and prolong machine life.
Hand Scraping

To ensure consistent high quality, each slide way is hand-scraped. Each axis saddle has Turcite material on it and also has a special "*" design that is used along with a "Z" pattern for efficient oil troughs. There is an excellent distribution of oil to all axes, so setting time after rapid movements is greatly reduced 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.
Double Stoppers Design

To prevent any deviation between the servomotor housing and ball screw bearing housing, each axis is equipped with two stoppers to guarantee absolute axial alignment.

Stiff Ball-Screw Design for Greater Axial Support

All three axes use ISO C2 Class precision ground pre-loaded ball screws with pre-tensioned supports on both ends to minimize backlash and compensate for thermal-induced error.
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 easy of troubleshooting
Volumetric Oil Distributor

Lubricating oil is evenly distributed to all the sliding surfaces of the machine via volumetric oil distributors. All stationary lines are made of rigid alloy pipe and hard-plumbed for low maintenance operation over the life of the machine.
