The milling machine is one of the most versatile and widely used machine tools in metalworking. From simple flat surface machining to complex mold cavity work, from single-piece repair to mass production, milling machines handle the majority of non-rotational machining tasks in manufacturing.

As an engineer-driven, integrated manufacturing and trading machine tool provider, Botai Industrial Equipment has built a complete milling machine product line covering universal, CNC, turret, milling-boring, drilling-milling, gantry, horizontal CNC, and custom special configurations — delivering proven, cost-effective milling solutions for 7 core manufacturing industries.

Botai Milling Machine Naming System and Product Overview

Botai milling machines follow a unified naming system: B stands for Botai, M for Milling Machine, and the third letter indicates the type: U for Universal, C for CNC, T for Turret, B for Milling & Boring, D for Drilling & Milling, G for Gantry, and H for Horizontal CNC. Subsequent numbers indicate the worktable width or primary specifications.

Eight categories covering the full spectrum of milling operations:

CNC Milling Machines (BMC): The Backbone of Precision Machining

The CNC milling machine is the core equipment of modern machining shops. Botai CNC milling machines are available in three models — BMC-25, BMC-32, and BMC-36 — with worktable widths from 250mm to 360mm, accommodating parts of various sizes.

Structural Features:

• High-Rigidity Cast Iron Components: The base, saddle, worktable, column, and spindle head are all built from high-rigidity cast iron using resin sand molding and aging treatment, ensuring long-term dimensional stability.
• Dovetail Guideway Design: All X, Y, Z axis guideways use dovetail design, eliminating low-speed crawling and ensuring smooth feed motion.
• High-Precision Ball Screws: All three axes use high-precision, high-strength ball screws for fast feed rates and high positioning accuracy.
• Comprehensive Protection: Guideways and ball screws are fully enclosed, ensuring lasting transmission and motion precision. The exterior features a full-enclosure design for safety and reliability.

CNC milling machines are widely used in mold making, automotive parts, and general mechanical component precision machining.

Turret Milling Machines (BMT): The Flexible Choice for Multi-Angle Machining

Turret milling machines offer exceptional machining flexibility through their unique swivel-head design. Botai turret milling machines come in three models — BMT-23, BMT-25, and BMT-30 — with worktable widths from 230mm to 300mm.

As 3-axis CNC milling machines, the BMT series provides broad versatility with a rich selection of accessories, capable of milling, boring, and drilling operations. Their greatest strength is the ability to machine complex workpieces without dedicated fixtures — such as cams, profiling plates, and complex-shaped jigs — making them ideal for mold repair, new product prototyping, and multi-variety small-batch production.

Milling & Boring Machines (BMB): Combined Milling and Boring for Housing Parts

The Botai milling & boring machine, model BMB-101, adopts a single-column, side-mounted layout. The worktable uses four-point positioning with manual rotation. X, Y, Z axes are CNC-controlled for 3-axis simultaneous motion; the boring spindle feed can be servo-motor controlled for automatic extension and retraction.

The core advantage of milling-boring machines is combined milling and boring in one setup, making them ideal for hole-system machining of housing components — such as gearbox cases, pump bodies, and valve bodies where positional accuracy is critical.

Drilling & Milling Machines (BMD): Multi-Function Economical Machining Equipment

Botai drilling & milling machines come in two models — BMD-24 and BMD-32 — suitable for small-to-medium part machining, with particular strength in non-ferrous metals, plastics, and nylon.

Functional Features:

• Multi-Function Capability: Drilling, milling, boring, grinding, and tapping in one machine
• Flexible Adjustment: Spindle head swivels 90° left/right in the vertical plane; worktable rotates 45° left/right in the horizontal plane
• Automatic Feed: Worktable longitudinal auto-feed significantly improves machining efficiency
• Stable Structure: One-piece cast iron base for enhanced stability and precision

Drilling & milling machines are widely used in single-piece and small-batch mechanical manufacturing, instrument industries, construction decoration, and repair departments — making them an extremely cost-effective universal machining solution.

Gantry Milling Machines (BMG): Efficient Machining of Large Complex Parts

The Botai gantry milling machine, model BMG-80, features an 800mm worktable width and a gantry structure with outstanding rigidity and load capacity.

The gantry milling machine performs CNC milling, boring, drilling, and tapping operations on steel, cast steel, and cast iron workpieces. Using accessory heads, the machine can complete drilling, milling, boring, reaming, and tapping on various disc, plate, housing, and mold components in a single setup. It is especially suited for efficient machining of small-to-medium batches, with clear advantages for complex, high-precision parts. It can also be integrated into automated production lines for mass production.

CNC Horizontal Milling Machines (BMH): Specialized Equipment for Deep Cavities and Grooves

Botai CNC horizontal milling machines come in two models — BMH-32 and BMH-40 — with worktable widths of 320mm and 400mm respectively.

Horizontal milling machines feature high structural rigidity and precise stability. All three primary guideway pairs incorporate wear-resistant measures for long-lasting accuracy retention and service life. They are suitable for cylindrical, circular, angular, form, and face milling cutters for machining flat surfaces, inclined surfaces, angles, grooves, and edges.

With accessories such as dividing heads installed, horizontal milling machines can also machine gears, reamers, spiral grooves, cams, and drum-shaped workpieces — widely used across all machining industries.

Universal and Custom Milling Machines: Covering Broader Demands

Universal Milling Machines (BMU) provide economical and reliable manual milling capability for startup workshops, training, and repair scenarios.

Custom Special Milling Machines represent Botai's "integrated manufacturing & trading" differentiation. Our technical team collaborates with partner factories to develop application-specific milling machines or combined processing solutions based on your part drawings and process requirements — from non-standard workpiece adaptation to production line integration. Your requirements, our engineering.
