RUGGED CONSTRUCTION ASSURES OPTIMUM RIGIDITY AND STABILITY

The major structural parts are manufactured from high-quality Meehanite cast iron (FC-30), hardened to over HB190 and tempered to relieve stress.

Box ways on the three axes. Way surfaces are hardened to, over HRC55 with over 2 mm depth.

Three axes are equipped with class C3 and 40mm (QV117 / QV127 / QV147) and 50mm (QV159 / QV179 / QV209) diameter precision ball screws.

Counterbalance weight moves on a guide shaft for added stability and straightness accuracy.

COUNTER WEIGHT BALANCE SYSTEM

Exclusively designed counterweight balance system. The counter-balance weight moves on a guide shaft to assure movement straightness accuracy. There is no vibration in the forward/backward and the right/left directions. This creates superior workpiece surface accuracy to meet various mold machining requirements. Patented in Taiwan and China.

RIGID, PRECISION SPINDLE ASSURES HIGH-QUALITY MACHINING

• Supported by superior precision P4 class bearings, the spindle provides an extra wide range of machining capacity and high speed.
• Floating unclamping system assures unclamping tool force will not transmit to the spindle bearings. It provides stable tool clamping and unclamping with the spindle and extends the spindle bearings' life.
• The spindle is a cartridge-type.
• Choice of various spindle speeds - 6,000 rpm (ISO50, Belt Type/Gear Type), 8,000 rpm (ISO40/ISO50, Belt Type) 10,000 rpm (ISO40, Belt Type), 12,000 rpm (ISO40, Belt Type).
• The circulating oil cooling system on the spindle head prevents thermal expansion and offers the best precision machining environment.

CHIPS FLUSHING NOZZLES

Coolant flushing nozzles on the rear inner wall of guard prevent the jam of chips during operation.

COUPLINGS

Directly connected with ball screw and AC servo motors, the high precision flexible couplings offer the best rigidity and keep the accuracy of axial linear assembly under high-speed movement.

AUTOMATIC LUBRICATION SYSTEM

The Lubrication System automatically measures and accurately distributes the oil to the slide ways, ball screws, and bearings.

CONTROL SYSTEM

The centralized control panel employs a touch sensing screen for user-friendly operation. The humanized designed control panel has an elegant appearance. Various controllers can be chosen - Mitsubishi, Heidenhain, Fanuc and Siemens.

SPLASH GUARD

The full-enclosed splash guard meets environmental protection and CE requirements. It offers users a comfortable working environment.

Triple Processes for Multiple Rigidity

Superb Mechanical Structure features outstanding damping coefficient. All the key structural components are made from Meehanite cast iron.

1. The melted iron is annealed in the furnace.
2. The cast iron is stress released in the electric over at 600
3. High-frequency induction hardens the slide ways

Four Slide Ways: To maintain absolute rigidity and to keep motion controls extraordinary sensitivity the machine base with four slide ways is the best technical solution. This is incorporated in Pinnacle machines.

The ISO50 direct drive spindle of QV series is powered by a high-torque dual winding servo motor, featuring smooth, high-speed power output for the quality surface finish of the workpiece.

It is designed for high volume chip removal performance; the Pinnacle QV series machine is your mightiest equipment for mold making or mass production jobs. From high-speed ISO40, 15000 rpm to high torque output of ISO 50 gear box, the QV series machines satisfy your machining demands effectively.
