Rotary-Vane Vacuum Pump (2X)
Classification of gantry type Milling Machine Gantry Type Milling,Gantry Type Milling Machine,Gantry Milling,Gantry Milling Machine,Gantry machining center Jiangsu Hoston Machine Tools Co., Ltd. , https://www.hosdunmachinetools.com
Applications & Features:
1.Starting up directly from Atmosphere Pressure for Evacuation.
2.Used either solely as Rough Pumps, or in combination with other high vacuum pumps as Backing Pumps.
3.They find wide application in the fields of metallurg, chemical, light industry, medical, electronics and LSI industries.
4.They can not be used for evacuating the oxygenic, poisonous and explosive gasses and gasses with can react with pump oil easily. Neither can they be used as compressor and transmission pump.
5.Such series XD of progressional vacuum pump is one of the indispensably equipments of light industry, food industry, delicate chemical and products of draught plastics.

(1) Divided by form
According to whether the gantry is moving, it is divided into a gantry fixed table mobile type (about 90% or more) and a gantry mobile type (also called bridge type).
The bridge type gantry milling is characterized by a small footprint and a large carrying capacity. The gantry travels up to 20 meters, making it easy to machine long or heavy workpieces.
According to whether the beam moves on the column, it is divided into two types: moving beam type and fixed beam type; the beam moving on the elevated bed is called overhead type.
(2) Divided by system
It is divided into ordinary type and CNC type. There are also manufacturers to develop digital intelligent gantry milling with ordinary milling and CNC Milling – one button conversion, which is more flexible and practical.
(3) Divided by capability
It`s divided into light, medium and heavy (super heavy) gantry milling.
Performance characteristics
The gantry milling machine has sufficient rigidity, high efficiency, convenient operation, simple structure and comprehensive performance.
The specific performance characteristics vary according to the type, model and manufacturer, and have a lot to do with the technology used.Taking the SK series three-axis CNC gantry milling mentioned above as an example, its performance characteristics are:
1. The vertical milling head is equipped with TX400 heavy-duty gantry milling head, double rectangular guide rail, with strong rigidity;
2.Milling head mounted ball screw, pneumatic broach device, servo motor drive;
3.The side milling head is equipped with a V5 gantry milling head with an independent lubrication device. The lifting is driven by an ordinary reducer, and the frequency control is adopted;
4.Universal milling/CNC milling one-button conversion three-axis CNC system, which can be programmed and operated manually by the expansion panel, which is extremely implementable in the actual machining process;
5.The bed is advanced and retracted, the beam is up and down, and the vertical milling head is equipped with a Taiwan ball screw, which is driven by a servo motor;
6.With timing belt and synchronous wheel;
7.Hand-held electronic handwheel unit for easy three-axis tool setting;
8.Unique beam lifting safety interlocking device to ensure the repeatability of the machine tool;
9.The station standard cycloid pump group is continuously lubricated with low failure rate.
